Tomatoes like to be cold and dry, but it is hot and rainy in summer, and tomatoes that grow indefinitely are easy to grow white, resulting in unbalanced fertility.

In order to regulate the growth and development of tomato in summer, cultivate healthy plants, enhance the plant's ability to resist pests and diseases, increase yield and improve quality, on the basis of appropriate sparse planting and reasonable fertilizer and water management, precise pruning is also particularly important. 1, single stem pruning to remove the buds of the organs, and remove the axillary buds under the lower nodes and flower spikes as soon as possible.

For varieties with small seedlings and strong growth potential, three axillary buds should be left to regulate growth. But it should be noted that if you leave too much, the first ear will bear poor fruit.

After the third ear blooms and bears fruit, the axillary buds are gone. Especially the axillary buds under the flower spike should be removed as soon as possible.

2. After the ear bud harvested by coring plan is confirmed, when the ear below it blooms, leave two leaves on the bud for coring. Because the ovary at the top of the core is full and bears good fruit, you can get big and excellent fruit.

Be careful not to delay. 3. There are two kinds of picking leaves, one is picking leaves when the growth is too strong.

According to moderate leaf picking, growth can be inhibited. When the fifth ear blooms, no fruit can be seen from the working path, indicating that the vegetative growth is too vigorous.

Remove the leaves covering the fruit to inhibit growth. Because when the growth is too strong, the leaves must be big and long, covering the fruit, which is the main reason for the formation of hollow fruit, so it is best to remove the compound leaves covering the fruit or half a leaf.

The other is picking leaves to prevent the occurrence of pests and diseases. After the harvest begins, remove the leaves under the harvested ear to make it well ventilated and prevent the occurrence of pests and diseases, but leave about 10 for each plant, and do not pick the leaves excessively. Remove closed leaves with overlapping leaves.

In addition, pruning and leaf picking should be carried out on sunny days as far as possible. Tips for increasing tomato yield Layered cultivation can increase tomato yield, especially in greenhouse.

The method is to leave 1 ~ 2 lateral branches at the bottom of the main branch after the tomato tops the peak. When the equilateral branches grow to 23 cm -26 cm high, remove two-thirds of the leaves, bend them to the ground, fix them with soil strips, and expose 2 -3 leaflets at the top. After all the lateral branches in a border are fixed, water them once.

Under suitable temperature conditions, strong roots will grow in the earth pressure part. After the main branch of tomato decays, cut the main branch from the upper part of the compressed side branch immediately and strengthen management, and the side branch will soon blossom and bear fruit.

In winter, after tomatoes are layered in plastic shed or greenhouse, the temperature in greenhouse or indoor can be controlled at 20℃-25℃ during the day, 10℃- 15℃ at night, and the soil humidity is 45%-55%. This will not affect the growth of the fruit in the late stage of the main branch, but also help the lateral branches to take root.

The tomato varieties with good topping and pruning benefits should be hybrids with disease resistance, high yield, high fruit setting rate and high quality. Suitable stubble can be stubble in early spring, late autumn and wintering.

Sowing dates suitable for local conditions should be selected. After soil preparation and fertilization, 8,000 kg of high-quality decomposed farmyard manure, 50 kg of diammonium phosphate, 35 kg of potassium sulfate and 40 cm depth of urea 10 kg were applied to make a concave ridge with a width of 1.2 m and a height of 20 cm, and the center of the ridge was watered and ditched.

When planting in autumn and winter, it is necessary to ensure that the greenhouse film is not damaged and has the function of rain protection and cooling. Single row planting per border, spacing between plants 35 cm, per mu 1800 plants.

Pruning method Continuous pruning of greenhouse tomatoes can obviously increase the harvest of high-quality fruits. The main supporting techniques are as follows: first, when the first inflorescence of the trunk of the basic branch is in full bloom and the second inflorescence is about to bloom, two leaves are left on the upper part of the second inflorescence to be picked as the first basic branch; At the same time, leave a lateral branch at the lower part of the first inflorescence of the first basic branch, and knock off the rest; When most of the first inflorescence of this lateral branch blooms and the second inflorescence is about to bloom, leave two leaves on the upper part of the second inflorescence as the second basic branch; Then leave a side branch under the first inflorescence of the second basic branch as the third basic branch; Picking five times in turn, surrounding five fruiting branches, each bearing 10 ear; After the second inflorescence has blossomed and is treated with the anti-falling agent, hold the base of the first inflorescence with the right hand, twist it outward by 85 to 90 degrees, and then gently press it down to make it nearly perpendicular to the last basic branch, which meets the requirements of twisting the branch.

Are you talking about tomatoes in summer?

The growing season of summer tomato is in high temperature season, the epidemic of diseases such as virus disease, stem rot and cotton wilt, the outbreak of pests such as aphids, whiteflies and mites, and the influence of high temperature, strong light and dry environment often make the planting management of summer tomato difficult and make vegetable farmers nervous.

In view of the past experience and lessons, two problems should be paid attention to in the process of tomato cultivation and management in summer.

1. Change flat border cultivation to ridge cultivation. Flat border cultivation is not only easy to cause waterlogging in the border, but also easy to cause the prevalence of soil-borne diseases, so flat border cultivation should be changed to ridging cultivation. If there is already a shed for flat border cultivation, it can be combined with soil cultivation to turn the border center into a ridge back several times. Generally, it is completed in 2-3 times, so as to avoid too much soil covering at one time affecting root growth and reducing absorption capacity.

Second, change the pruning method. It is hot in summer, and the problems caused by pruning straight stems, such as excessive plant growth and poor fruit, can be solved by continuous topping, changing heads to dry and pruning for three months. When the first and second inflorescences bloom one after another, leave two leaves above the second inflorescence for coring. Choose one of the most robust lateral branches to keep and continue to grow up as the middle trunk. By using this method, continuous coring treatment can form a curved and compact plant shape, which is beneficial to reduce the damage of strong light and high temperature, with higher yield and better quality.

Tomatoes are commonly known as tomatoes

The best time to plant tomatoes in a year is at the end of March, that is, the end of winter.

Steps for planting tomatoes:

You can buy some bagged tomato seeds. Or, you can pick some seeds from tomatoes while eating, then rinse them with water and dry them for later use.

2. Find some empty yogurt pots, put some mixed fertilizer in them, plant tomato seeds in the center of each pot, slightly below the surface of the fertilizer, bury them and gently pour some water.

Put a clear label on the jar and put it on the sunny windowsill. Check it every day, water it as needed, and the amount of water is appropriate to feel wet every time you touch the fertilizer with your fingers. Remember not to over-water. You should be able to see the unearthed buds in a week:)

4. After four weeks, the buds will grow into buds. Gently take these seedlings out of the jar, try to keep the roots intact, and pay attention to avoid damaging the roots of the seedlings. Transplanting the tender seedlings into a larger flowerpot, which is filled with seed mixed fertilizer. Pay attention to movement when planting plants and fixing their positions.

5, regular inspection, watering. You can see the flowers in a few weeks. Backward flowers will leave small green tomatoes.

6. When your tomatoes are bright red and soft to the touch, it means they are ripe. You can pick it and eat it.

How to grow tomatoes?

1. Planting management: When planting tomatoes in autumn and winter, the ground temperature is high. After planting, you can not cover the plastic film first, water it in time, spray a new high-fat film to keep moisture and keep warm, improve soil permeability and promote tomato root system to be deeply rooted.

2. Field management: After tomato planting, topdressing and watering should be done in time according to the growth demand, pruning and raking should be done in time, and the old diseased leaves at the lower part should be removed, so as to improve the microclimate environment in the field. At the same time, the vegetable fruit Zhuangdiling should be sprayed before flowering, young fruit stage and expansion stage of tomato to increase nutrient transport, promote rapid fruit development and improve plant disease resistance and stress resistance.

3. Disease control: Tomatoes planted in autumn and winter are prone to early blight, leaf mold, gray mold, late blight and other diseases. It is necessary to spray targeted chemicals in time to kill, and spray a new high-fat film to form a protective film, which greatly improves the utilization rate of effective components. Pay attention to the application of drugs on the back of leaves when spraying drugs.

How to grow tomatoes

1. When sowing and raising seedlings, the land must be watered. Sow when the soil is slightly dry. After sowing, cover the surface with 0.5 cm soil (before sowing, soak the seeds in warm water at 50~55℃ 10 ~ 12 hours, take them out and sow them directly in the ground, usually 10 ~ 12 hours.

2. When the tomato seedlings grow to three or four leaves, you can dig out the seedlings, and be careful not to hurt the roots when digging out. Leave some soil at the roots of the seedlings, then plant them directly in the ground, straighten the plants, and then water them until they are thoroughly watered.

3. When planting tomatoes, water them once and thoroughly, and then water them every 3 to 5 days. Tomatoes need to be watered before they bear fruit. Just keep the land moist after they bear fruit.

4. After planting in the ground, it needs to be watered and fertilized for 10 days, and decomposed chicken manure, sheep manure or pig manure can be applied before flowering.

It can promote flowering and fruiting by properly raking out new buds.

5. When the pruning time is higher than 80 cm, the top should be topped and the top leaves should be removed. Because the bearing capacity of tomato seedlings is limited, too many fruits will be overwhelmed and fall down. In order to ensure the quality and shape of fruits, pruning is necessary.

Tomato, the scientific name of tomato, contains rich and varied nutrition and has a beautiful and charming appearance; Not only the food is delicious, but also the fruit is beautiful. It has many functions and is called the magic fruit in dishes.

Tomatoes, like watermelons, can be used to relieve summer heat and quench thirst. However, the content of vitamin C in tomato is about 10 times that of watermelon. Moreover, due to the protection of organic acids, the vitamin C contained in it is not easy to be destroyed during storage and cooking, and the utilization rate of human body is very high. Therefore, eating tomatoes often plays an important role in treating scurvy, allergic purpura, colds and promoting wound healing.

The sugar content of tomatoes is also very high, about 1.5%-4.5%, and most of them are glucose and fructose which are easily absorbed directly by human body. Tomatoes are also rich in carotene and vitamin B family, including rutin, which has a certain effect on protecting vascular health and preventing hypertension.

The content of various vitamins is 2 -4 times higher than that of apples, pears, bananas and grapes. It contains various minerals accounting for 0.6% of its total weight, among which calcium and phosphorus are more, followed by zinc and iron, and trace elements such as manganese, copper and iodine. These minerals are especially beneficial to the growth and development of infants and children.

How to grow persimmons?

Persimmon cultivation technology Persimmon belongs to the genus Persimmon of Persimmon family, which is an ancient economic tree species widely cultivated in China. There are many varieties. Generally, according to whether it can be naturally astringent before maturity, it can be divided into two categories: sweet persimmon (completely sweet persimmon, incomplete sweet persimmon) and astringent persimmon.

Sweet persimmon is favored by people because of its astringency, good taste and rich nutrition. Persimmon cultivation in our state has a long history. The main varieties are local large flat persimmon (also known as seedless persimmon), fire persimmon, water persimmon and so on. In recent years, a large number of Japanese sweet persimmons have been introduced and planted.

Persimmon is a deciduous tree, tall, with a natural semicircular crown, oval, oval or inverted leaves, 6- 18 cm long and nearly leathery. The surface of the leaves is dark green and shiny, and the back of the leaves is light green. Monoecious or dioecious, the berries are ovoid or oblate, orange or bright yellow and red.

The flowering period is from May to June, and the fruit ripens in September-165438+ 10. Persimmon has good economic and physiological characters, the yield per plant can reach more than 100 kg, and it is resistant to storage and transportation. It can be used in brewing industry and has high medicinal value. It is a tree species with high economic benefits.

The main ecological factors affecting the growth and fruiting of persimmon trees are temperature, light and water. The altitude is above 1000m, and the most suitable condition is the annual average temperature 13- 19℃. The area with an average temperature of 20-25℃ in September and 10/6℃ in October is suitable for development, and the area with an annual average temperature lower than 9℃ is damaged by freezing.

Hi-light, especially in the fruit expansion period, requires sufficient light, and the requirement for water is that the annual rainfall is not less than 500 mm, and it is resistant to waterlogging and barren. 1. Garden construction (1) Garden selection should be built on a gentle slope with convenient transportation, concentrated contiguous land, deep and fertile soil layer, good drainage, clay or sandy loam soil and sunny lee.

(II) Variety Selection Persimmon varieties suitable for planting in our state are Fu You, Jiro, Zen Temple Pill, Flat Persimmon, Fire Persimmon and Water Persimmon. The first three are sweet persimmons, followed by astringent persimmons. Sweet persimmon varieties should be planted with pollinated trees, and all three varieties can be pollinated trees, and the ratio of pollinated trees is about 8∶ 1.

(3) Seedling colonization 1, colonization time: from defoliation to germination, sooner rather than later. The suitable planting time in our state is from June 165438+ 10 to February of the following year.

2. Planting density: the plant spacing is 3 m *4 m ~4 m *4 m, and the planned close planting is 2 m *3 m, giving priority to the promotion of planned close planting. 3. Planting method: the flat land is square, the dense planting is rectangular, and the mountain area is triangular or planted along the contour line.

The size of planting holes should be different according to the soil quality. Generally, planting holes should be 0.8 meters square. Before planting, apply 3000 kilograms of farm manure per mu for about 10 day, and fill it into the planting hole after fully mixing with the topsoil. Grafted seedlings with robust growth and diameter above 0.6 cm are selected and planted in winter from 1 1 2 to 12 and in spring from February. When planting, the seedlings are vibrated and filled with soil, so that the soil can fully flow into the gaps in the roots, and the seedlings are gently lifted and aligned along the line. The best planting depth is that the soil grain of the nursery is parallel to the ground of the planting pit, and the soil is compacted while filling the soil.

After the seedlings are planted, dry them 60 cm from the ground. 2. Garden management (1) Rational fertilization 1, young tree fertilization: the first fertilization is completed before the defoliation dormancy, and farm manure 15 ~ 20kg, compound fertilizer 0.3kg and calcium superphosphate 0.5kg are applied in the furrow.

The second fertilization was carried out in early May, with farmyard manure 10 ~ 20kg and urea 0. 2 kg and potassium sulfate 0. 35 kg per plant. 2. Fertilization of fruit trees: the first fertilization is completed before the defoliation dormancy, and each plant is applied with 20-30 kg of farm manure, compound fertilizer 1 kg and calcium superphosphate 1 kg, and applied into the annular ditch.

Apply secondary fertilizer after physiological fruit drop to promote fruit hypertrophy. 30-40 kg of human excrement and urine, 0 .6 kg of urea and 0 .6 kg of potassium sulfate were applied to the plant, and several * * * were poured into the tree tray. The third fertilization is carried out after the fruit is harvested, mainly applying nitrogen and potassium fertilizer to supplement the nutrient consumption of the tree. Apply 20-30 kg farm manure, 0. 1 kg urea and 0 .2 kg potassium sulfate to the tree tray.

3. Fertilization method: The absorption root groups of persimmon are concentrated in the middle and outside of the crown, and the soil layer is less than 40 cm. Fertilization should be applied at the periphery of the crown. When fertilizing on the flat land, the topsoil inside and outside the crown should be peeled off, shallowly turned 6~ 10 cm, and thoroughly poured back to the soil; Taking the trunk as the center, several radial fertilization ditches with shallow inside and deep outside were opened.

Fertilization in mountainous areas mainly adopts hole application or furrow application. Dig a pit or furrow between the plants inside the terrace or outside the canopy to fertilize, and then cover the soil.

(2) The ideal soil conditions for persimmon cultivation are deep soil layer, strong water and fertility conservation and good drainage. However, persimmons are generally planted on hillsides, and the physical properties of the soil are poor. The common disadvantages are more gravel, high hardness of clay, weak water retention and serious erosion. In view of the above shortcomings, it is most effective to directly use organic materials (such as peat, bark compost, etc.). ) Not easy to decompose. Planting grass or interplanting green manure can also be used to gradually achieve excellent physical properties or topsoil mulching and drip irrigation to achieve the effect of soil and water conservation.

Alkaline calcareous soil can be used to neutralize acidity and applied once a year after fruit picking or dormancy. When the pH value is less than 4 .2, it can be applied twice a year. The application of calcareous materials should be gradual, not excessive at one time, and should be carried out with composted organic fertilizer to increase the content of soil organic matter and improve soil fertility. Third, the persimmon with sparse buds, flowers and fruits is easy to bear fruit in the second year, the fruit becomes smaller and the commodity value is low. It is advisable to sparse buds, flowers and fruits.

Generally, the fruit in the middle of the fruiting branch is large, mature early, well colored and high in sugar content. Therefore, when thinning buds and flowers, all tips and late flowers of fruiting branches should be thinned out, and 1 parallel buds should be removed, leaving only 1~2 buds from the base to the middle of fruiting branches, and the rest should be thinned out.

The best bud thinning period is when the buds can be twisted with your fingers. Fruit thinning can be carried out at the end of physiological fruit drop, and all fruits with poor development, sepal damage, abnormal fruit, pests and diseases, and easy sunburn will be thinned.

The degree of fruit thinning must match the number of leaves in branches, and the leaf-fruit ratio is generally controlled at 15 leaf-leaf ratio 1 fruit. 4. Plastic pruning 1, young tree pruning: Young trees should be lightly pruned, with short branches as the main pruning in winter, supplemented by thinning branches, in order to increase branches, promote transformation and lay a good foundation for early high yield.

2. Pruning of fruiting trees: pruning in winter is mainly based on thinning, shortening the main branches and expanding the crown. In summer, lure the main branches and pick the long branches. For rich varieties, the fruiting mother branch cannot be shortened, and thinning more is the main skill. 3-4-year-old fruiting mother branches need to be drained and regenerated to promote vigorous fruiting.

How to grow cherry tomatoes?

Cherry tomato is a tropical crop introduced from Taiwan Province Province, also known as pearl tomato, which can be used as vegetables and fruits. The fruit is about 1 ~ 3cm in diameter, bright red, transparent, sweet, seedless, good in taste, high in nutritional value and unique in flavor. Both edible and ornamental, it is favored by consumers. The plant of this variety grows rapidly, the fruit can be matured in 70 days after planting, and the yield per mu is more than 4000 kilograms after continuous picking for 3 months, with good benefits.

How to plant cherry tomatoes;

1, timely sowing. This variety is suitable for autumn sowing. In order to prevent the spread of the virus, the seeds should be disinfected before sowing. The seeds should be wrapped in gauze and soaked in 15% trisodium phosphate aqueous solution for 10~20 minutes. Then, open the gauze, take out the seeds, wrap them with wet cloth and put them at 25~30℃ to accelerate germination. Wash the seeds with warm water 1~2 times a day. After 2~3 days of accelerating germination, the seeds can be sown and raised when they are white.

2. Soil preparation, border planting and reasonable close planting. Cherry tomatoes in Taiwan Province Province are suitable for planting in paddy fields after early rice harvest in this city, and planted in sandy loam with convenient irrigation and drainage, fertile soil and good ventilation. Before planting, deeply harrow, and apply artificial soil or mushroom soil 1000 kg and calcium magnesium phosphate fertilizer 150 kg per mu. Then, the ridge width is 80~ 100 cm, the ridge height is 30~35 cm, and the trench width is 40 cm. When the seedlings grow to 4-5 true leaves, two rows can be planted in each border with a row spacing of 35-40 cm and 2500-3000 plants per mu.

3. Fertilizer and water management. Due to the large growth, long fruiting period and high yield of tomatoes in Taiwan Province Province, the supply of fertilizer and water should be sufficient. After planting 10~ 12 days, water and fertilizer can be combined and thin fertilizer can be applied frequently. During the flowering and fruiting period, combined with ditching and soil cultivation, 50 kg of artificial compound fertilizer was applied per mu. After entering the full fruit stage, water and fertilize every 15~20 days 1 time to keep the soil moist. Combined with pest control, topdressing outside the roots and spraying 600 times of Gao 'an Susu No.4 solution for 2~3 times can achieve the purpose of improving quality and increasing yield. During the whole growth period, the amount of fertilizer per mu needs 20 kg of pure nitrogen, 25 kg of phosphorus pentoxide 15 kg and 25 kg of potassium oxide. The ratio of nitrogen: phosphorus: potassium is 1:0.67: 1.2.

The nutritional value of cherry tomatoes is better than that of ordinary tomatoes. The cherry tomatoes contain special substances such as cereal, sweetness and lycopene, which can promote the growth and development of human body, especially the growth and development of children, increase the resistance of human body and delay human aging.

How to grow tomatoes?

Tomato is the most common crop in the family garden, and it is also an indispensable vegetable in the garden. Although this summer fruit and vegetable is easy to grow, if you expect a bumper harvest and avoid pests and diseases, you must master ten skills, which can help you grow beautiful and delicious tomatoes from seedling raising to harvest. 、

1, the seedlings should be planted thinly to avoid crowding.

When using seeds to raise seedlings, a few more seeds are often buried in each seedling pot to ensure the germination rate. But when the seedlings grow, they must be transplanted separately, and two trees should not be crowded together, otherwise they will compete for nutrients and affect their growth. Tomato seedlings have strong vitality and high tolerance for points. As long as you see the real leaves growing, you can plant them alone in a bigger flowerpot and wait for them to be moved to the garden.

2. Strengthen before planting the vegetable garden.

Before transplanting seedlings from indoor to vegetable garden, they should go through at least one week of intensive period to adapt to the outdoor environment. Move the seedling pot outdoors in the morning, fill it with water, and put it in a direct sunlight one or two days ago to avoid burning the leaves, and then move it indoors at night. In the next few days, the time of direct sunlight gradually extended.

3. Eggshell is used as base fertilizer to supplement calcium.

Eggshell is an excellent source of natural calcium, but calcium is usually lacking in soil. Calcium can produce two functions: on the one hand, it can adjust the water demand of tomato plants and avoid peel cracking or rotten tail when the climate is too wet, too dry or irregular; On the other hand, calcium can also help the taste of tomatoes reach its peak. Before transplanting tomato plants, it is best to put a broken eggshell as base fertilizer in the planting pit and fill it with some humus soil. You can go to the cake shop to get eggshells, or you can go to the gardening center to buy calcium-containing organic fertilizer.

4. Wait until mid-May before transplanting.

Tomato is a tropical crop, and it will rot when it is cold. It must wait until the temperature stabilizes above 50 degrees Fahrenheit at night before it can be safely transplanted from indoor to vegetable garden. In high latitudes, the climate may be hot and cold in the first two weeks of May, and the transplantation will not be carried out until at least May 15. Experienced people think it's not too late to wait until June 1.

5. Change the position after planting for two years.

The spores of each plant disease have a specific host. After tomatoes are planted in the same place for two years, fungal spores causing tomato diseases are hidden in the soil, so it is best to change the planting place every two years. If the environment does not allow, we should dig out the old soil as much as possible, fill it with humus and topsoil in half ratio, or replant it in a big pot filled with fresh soil, and the diameter of the pot mouth should be at least 12 inch to 15 inch.

6. Choose the right planting place and enjoy the sunrise.

Before transplanting tomato plants outdoors, it is necessary to observe the possible planting sites, and it is ideal to let tomatoes receive the longest sunshine in the morning. If the dew stays on the leaves for too long in the morning, fungal spores are most likely to reproduce. If the planting area is exposed to the morning sun, the disease can be effectively prevented by removing the morning dew.

7. Great room for growth to prevent diseases

Tomato plants are too crowded and the air circulation between branches and leaves is poor, which is the most likely to lead to diseases. Tomato vines look petite, but they grow rapidly after being planted in the garden. The diameter of each vine of some creeping varieties is as long as 10 to 14 feet. When buying seeds, you should know the volume of the last mature plant, so as to provide enough growth space.

8. scaffolding is needed to be healthier.

If there is no support frame, it is not only messy, but also easy to make branches and leaves contaminated with fungal spores on the soil surface and get sick. Crawling tomatoes need scaffolding most, so that all the leaves can be exposed to the sun. Although the plants of clustered tomatoes are relatively straight, they are still prone to lodging when they grow up, and at least one column needs to be inserted for the plants to rely on. Many people buy ready-made "tomato cages" to raise plants. This cage is not practical and can't cope with the growth of tomatoes. It is better to build your own scaffolding according to your own needs.

9. Plant the pit as deep as possible.

Tomatoes have a feature that other vegetables don't have. Any part of branches and stems buried in the soil will grow auxiliary roots to absorb water and nutrients. According to this feature, when you transplant plants into the soil, you might as well dig the planting pit as deep as possible. After removing the leaves, two-thirds of the lower part will be buried in the pit, and only two or three inches of the ground will be exposed. In this way, the roots of deeply planted tomato plants will develop particularly luxuriantly, and the absorption capacity of water and nutrients will be greatly increased.

10, humus soil disease-resistant cover two inches.

After planting tomato plants, covering the bottom with 1 inch or 2-inch thick high-quality humus soil can not only prevent weeds and provide nutrients, but also contain countless microorganisms to prevent the invasion of germs.
