Pineapple cultivation technology
I. Garden
1. Garden selection Choose convenient transportation southeast or south-facing slopes to build a garden, if the selected plot of land is not a road, you should first open up the road; slopes less than 15 ° of the plot of land can be planted directly, the slope is greater than 20 ° of the terraces should be built on the same level of height.
2. Seedling selection Fengzhu pineapple to planting sand flooded Yue mainly, choose to grow strong crown buds or descent buds, which is the key to early results, to achieve high-quality cultivation.
3. Planting can be cultivated all year round, with April to May planting is the best, the survival rate is higher. Choose a sunny day planting, first turn the ground 30 cm deep, 1500 kg per mu of rotted chicken manure, calcium magnesium phosphate fertilizer 50 kg, and then do the bed, bed width 140 cm, bed spacing of 100 cm, plant, row spacing of 35 cm, planting 2,500 per mu; planting first according to the size of the plant will be the buds separated, and then peeled off the base of the 2 ~ 3 leaves, and 25% carbendazim 800 times the solution of the buds dipped in the base of 10 minutes. minutes, dry and plant. Planting depth of crown buds for 3 ~ 4 cm, descent buds to 6 ~ 7 cm is appropriate, after planting found dry, rot, missing plants to replant in a timely manner.
Second, soil management
1. Fertilization
① Seedling. After planting survival, with 0.3% urea plus 1% potassium chloride leaching solution for 2 to 3 times of extra-root fertilizer; the second year in the spring and autumn, each fertilizer 1 time, each time per mu of urea 15 kg, Barnett Bicar compound fertilizer 10 kg, magnesium sulfate 1.5 kg, zinc sulfate 0.5 kg.
② fruiting period. When the heart of the plant "red", inflorescence differentiation and development, timely application of good pre-flowering fertilizer, per mu of rotted chicken manure 800 kg, urea 15 kg, 15 kg of potassium chloride, magnesium sulfate 1.5 kg, zinc sulfate 0.5 kg, can increase inflorescences, increase the number of florets, increase the size of the fruit, increase yield. Timely fertilization after fruit picking, 500 kg of burnt soil, 700 kg of rotted chicken manure, 15 kg of urea and 10 kg of Bika compound fertilizer per mu, to restore the tree's strength and promote the growth of sucking buds, so that the tree can blossom and bear fruits in the following year at a suitable period. Winter low temperature before the arrival of discretionary fertilizer, potash-based fertilizer, can enhance the plant's cold resistance, reduce frost damage.
Pineapple with aerial roots, extra-root fertilizer can promote its growth and results, to achieve high-quality cultivation, so according to the needs of growth and results, with 0.2% potassium dihydrogen phosphate plus 0.3% urea mixed or with 1% potassium chloride leachate for many sprays, increase plant nutrition.
2. Plowing and weeding 1 time each in spring and fall. It can promote soil loosening and aeration, so that sucking buds produce a lower position, both to promote the growth of results, but also for the next year to lay the foundation for high yield.
3. Soil cultivation Combined with fertilizer cultivation after harvesting the fruit, promote root growth, so that the remaining sucker buds grow strong.
4. Covering In summer and fall, in order to maintain the soil moisture structure, increase soil organic matter, inhibit weed growth, and reduce soil temperature, cover with straw or weeds.
Three, plant management
1. bud treatment Timely and good selection of buds and bud retention, can focus on nutrition, promote fruit growth as well as the retained buds grow strong, improve yield and quality, for the next year's high yield to lay a good foundation.
① Crown buds. In the flower 50% to all open, crown buds grow to 5 ~ 6 cm high, left hand to support the fruit, the right hand will be small crown buds twisted and folded down, remove the crown buds must be carried out on a sunny day. If the rainy day pick buds, often due to the wound water, causing the fruit heart black rot, affecting fruit growth. If you stay in the crown bud for seedling use, should be 15-20 cm high crown buds, leaves open, brown dots in the axils of the basal leaves when removed.
② Descendant buds. Only select the fruiting peduncle at the base of the descent buds to stay as seedlings, the selected descent buds in the mother plant to grow to 18 ~ 20 cm high when taken, each plant to stay 1 ~ 2 descent buds, especially strong plants can stay 3; do not stay at the base of the fruit and fruiting peduncle in the middle of the descendants of the shoots, these descendants of buds in the growth of 3 centimeters high should be removed, removed in 2 ~ 3 batches.
③ Suction buds.
④ tuber buds. General tuber buds should be thinned out, but if the location of each sucker bud is relatively high, then stay tuber buds instead; there is no tuber buds have to stay high sucker buds, to be the next year after the flowering and fruiting of the plant collapsed, digging pits in the collapsed parts of the stem buried and mulched, prompting the latent buds of the stem to draw out to get the low sucker buds, to extend the life of the orchard.
2. Tree protection
① Protect the fruit from sunlight. In summer, the fruit around the 4 to 5 leaves bunched up or covered with straw on the fruit sunscreen, reduce sunburn, improve quality.
② cold and frost prevention. Low-temperature frost before the advent of straw to cover the plant, to protect the growing point, or smoked in the orchard to prevent cold.
Fourth, the application of plant growth regulators
1. flower catalyzing Timely flower catalyzing, to promote flowering and fruiting, can extend the fruit supply period, to meet market demand, improve economic efficiency. When the number of leaves on the plant reaches 35 or more, it can promote flowering. Flowering with 500~750 mg/kg 40% ethylene glycol or 15~20 mg/kg naphthalene acetic acid (sodium), take 20 ml of diluted solution to irrigate the heart, the higher the temperature, the lower the use of concentration, 25~28 days on the bud.
2. Promote fruit growth Combined with extra-root fertilizer, use Banetta Bicar potassium dihydrogen phosphate plus 0.3% urea plus 50~100 mg/kg gibberellin or 200 mg/kg naphthalene acetic acid (sodium), in the bloom of 50% and after flowering each spray 1 time, increase nutrition, promote fruit growth, improve quality.
Fifth, pests and diseases
Pineapple pests and diseases are less, the disease is mainly pineapple heart rot, bud disinfection with 25% carbendazim 800 times the solution of the seedling base dipped for 10 minutes after drying and planting, the onset of the early spraying of 70% thiophanate 1000 times the solution of the prevention and control; pests are mainly pineapple mealybugs, occurring in serious cases, the available turpentine synergistic (10 times the solution of the winter, 20 times the solution of the summer) spray.

2. pineapple head how to plant method pictures
Selected pineapple with a knife after the top bud cut off, tear off the lower layer of bracts, there is a shade outside the static 3 days, such as the incision is dry, put a few days and then hang the main plant is to collect a little bit of water is not so easy to rot.
?
Step 3: Take a transparent bottle filled with about half of the water, the top buds inserted into the root, about 7 days to see the tip of the root, turn on the pot planting. Pineapple in pots has no special requirements for soil, watering is not too diligent, see dry before watering. Rooting agent with or without can be, because the pineapple is easy to grow plants, 30 cm diameter pot enough.
?
Step 4: potted pineapple planted to ensure adequate sunlight, half a year of good management can start buds, from flowers to fruits about 200 days. Winter should be outdoor temperature of about 5 ℃ into the room for the winter, keep the light and often leaf surface moist, and so on the spring moved to the outdoors on the line.
?
Extension: pineapple growth habit
1, soil: pineapple on the soil adaptability is wider, due to the shallow root system is good gas, it is loose, well-drained, rich in organic matter, pH value of 5 ~ 5.5 sandy loam or mountain red soil is better, barren, sticky, poorly drained soil and high water table are not conducive to the growth of pineapple.
2, temperature: pineapple originated in South America tropical high temperature and arid areas, like warm, in the average annual growth of 24 ~ 27 ℃ is the most suitable, 15 ~ 40 ℃ range are able to grow, 15 ℃ below the growth of slow, 10 ℃ below the basic stop growing, 5 ℃ is the critical temperature of the cold damage.
3, water: pineapple drought tolerance, soil water shortage pineapple plants have the function of self-regulation, reduce the intensity of transpiration, slow down the respiration, saving water stored in the leaf to maintain life activities. Severe water shortage, the leaves are reddish-yellow, must be timely irrigation to prevent drying out. Excessive rainfall and high soil moisture will cause root rot and plant heart rot or withering.
4, light: pineapple original growth in the semi-shaded tropical rainforest, more shade-tolerant, due to long-term artificial cultivation and domestication of light requirements increase, sufficient light growth, fruit sugar content, good quality. Insufficient light is slow growth, high fruit acid content, poor quality. Light reduces 20%, yield drops 10%. But too much light, coupled with high temperatures, the leaves become reddish-yellow, the fruit is also easy to burn.
3. How to plant pineapple head the right way
Pineapple cultivation technology a, build the garden 1. Garden selection Choose convenient transportation to the southeast or south of the slopes to build the garden, if the selected plot of land without roads, should be the first to open up the road; slope less than 15 ° of the plot of land can be planted directly, the slope is greater than 20 ° of the terraces should be built on the same height.
2. Seedling selection Fenzhu pineapple is mainly planted in sandy flooded Yue, choose the crown buds or descent buds with robust growth, which is the key to early fruiting and realize high-quality cultivation. 3. Planting Cultivation can be carried out throughout the year, and it is the best to be planted in April~May with a higher survival rate.
Choose a sunny day to plant, first turn the ground 30 cm deep, 1500 kg per mu of rotted chicken manure, calcium magnesium phosphorus fertilizer 50 kg, and then do the bed, bed width 140 cm, bed spacing of 100 cm, plant, row spacing of 35 cm, planting 2,500 per mu; planting first according to the size of the plant will be the buds separated, and then peeled off the base of the 2 ~ 3 leaves, and 25% carbendazim 800 times solution of the base 10 minutes. Dip the base of the sprouts in 25% carbendazim 800 times for 10 minutes, dry and plant. Planting depth of crown buds for 3 ~ 4 cm, descent buds to 6 ~ 7 cm is appropriate, after planting found dry, rot, missing plants should be replanted in a timely manner.
Second, soil management 1. fertilizer ① seedling. After planting survival, with 0.3% urea plus 1% potassium chloride leaching solution for 2~3 times of extra-root fertilizer; the second year in the spring and autumn, each fertilizer 1 time, each time per mu of urea 15 kg, Barnett Bicar compound fertilizer 10 kg, magnesium sulfate 1.5 kg, zinc sulfate 0.5 kg.
② fruiting period. When the heart of the plant "red", inflorescence differentiation and development, timely application of good pre-flowering fertilizer, per mu of rotted chicken manure 800 kg, urea 15 kg, 15 kg of potassium chloride, magnesium sulfate 1.5 kg, zinc sulfate 0.5 kg, can increase the inflorescence, increase the number of florets, increase the size of the fruit, increase yield.
Timely fertilization after fruit picking, 500 kg of fire soil, 700 kg of rotted chicken manure, 15 kg of urea and 10 kg of Bika compound fertilizer per mu, to restore the tree's strength and promote the growth of sucking buds, so that the tree can blossom and bear fruits in the following year at a suitable period. Winter low temperature before the arrival of discretionary fertilizer, potash-based fertilizer, can enhance the plant's cold resistance, reduce frost damage.
Pineapple has aerial roots, and extra-root fertilizer can promote its growth and fruiting to achieve high-quality cultivation, so according to the needs of growth and fruiting, use 0.2% potassium dihydrogen phosphate mixed with 0.3% urea or 1% potassium chloride leaching solution for several sprays to increase plant nutrition. 2. Plowing and weeding In the spring and autumn seasons, each plowing and weeding for one time.
It can promote soil loosening and aeration, so that the location of the sucking buds is lower, not only to promote the growth of the results, but also to lay the foundation for the next year's high yield. 3. soil cultivation Combined with fertilizer cultivation after harvesting the fruits, to promote the growth of the root system, so that the retained sucking buds grow healthy.
4. Covering In summer and fall, in order to maintain the soil moisture structure, increase soil organic matter, inhibit the growth of weeds, and reduce the soil temperature, it is necessary to cover with straw or weeds. Third, plant management 1. bud treatment Timely and good selection of buds and bud retention, can focus on nutrition, promote fruit growth as well as the retained buds grow strong, improve yield and quality, for the next year's high yield to lay a good foundation.
① Crown buds. In the flower bloom 50% to all open, the crown buds grow to 5 ~ 6 cm high, the left hand to support the fruit, the right hand will be a small crown bud twisted and folded down, remove the crown buds must be carried out on a sunny day.
If the rainy day pick buds, often due to the wound water, causing the fruit heart black rot, affecting fruit growth. If you stay in the crown buds for seedlings, you should wait until the crown buds are 15-20 cm high, the leaves are open, and there are brown dots in the axils of the basal leaves.
② Descendant buds. Only select the fruiting peduncle at the base of the descent buds to stay as seedlings, the selected descent buds in the mother plant to grow to 18 ~ 20 cm high when taken, each plant to stay 1 ~ 2 descent buds, especially strong plants can stay 3; do not stay at the base of the fruit and fruiting peduncle in the middle of the descendants of the shoots, these descendants of buds in the growth of 3 centimeters high should be removed, removed in 2 ~ 3 batches.
③ Suction buds. Selected to stay in the bearing part of the low, robust growth of the sucker buds, in place of the mother plant, each plant to stay sucker buds 1 ~ 2, the other sucker buds sub-subsequent thinning, each thinning buds 2 ~ 3.
④ tuber buds. General tuber buds should be thinned out, but if the location of each sucker bud is relatively high, then stay tuber buds instead; there is no tuber buds have to stay high sucker buds, to be the next year after the flowering and fruiting of the plant collapsed, digging pits in the collapsed parts of the stem buried and mulched, prompting the latent buds of the stem to draw out to get the low sucker buds, to extend the life of the orchard.
2. Tree protection ① fruit protection from the sun. In summer, the fruit around the 4 to 5 leaves bunched up or covered with straw on the fruit sunscreen, reduce sunburn, improve quality.
② cold and frost protection. Low-temperature frost before the advent of straw to cover the plant, to protect the growing point, or smoked in the orchard to prevent cold.
Fourth, the application of plant growth regulators 1. flower catalyzing Timely flower catalyzing, to promote flowering and fruiting, can extend the fruit supply period, to meet market demand, improve economic efficiency. When the number of leaves on the plant reaches 35 or more, it can catalyze flowering.
Flowering with 500~750 mg/kg 40% ethylene glycol or 15~20 mg/kg naphthalene acetic acid (sodium), take 20 ml of diluted solution to irrigate the heart, the higher the temperature, the lower the use of the concentration, 25~28 days on the buds. 2. Promote the growth of fruits Combined with the extra-root fertilizers, with Barneda Bicar potassium dihydrogen phosphate plus 0.3% urea plus 50~100 mg/kg gibberellins or 200 mg/kg naphthalene acetic acid (sodium), in the flowering 50% and after the flower shedding each spray 1 time, to increase nutrition, promote fruit growth, improve quality.
Fifth, pest control pineapple pests and diseases are less, the disease is mainly pineapple heart rot, bud disinfection with 25% carbendazim 800 times liquid dip seedling base 10 minutes after drying planting, the early stage of the disease sprayed with 70% thiabendazole 1000 times liquid control; pests are mainly pineapple mealybugs, occurring in serious cases, available turpentine synergist (10 times liquid in winter, 20 times liquid in summer) spray.
4. Polo`s head planting method
Pineapple honey planted after many years of non-fruit, or nutritional growth is too strong to affect the flowering and fruiting, seriously affecting the fruiting rate.
To improve the fruiting rate of pineapple honey, it is necessary to physically control the tip and chemical flower promotion two ways and use. The traditional method is in the trunk, the main branches of the bark ring peeling or ring cutting, so that more nutrients are accumulated in the above ground branches, peacock fish, to promote the pumping of fruiting branches of the flowering and fruiting; or in the trunk of the main branches of every 30cm carving (with a knife, axe can be chopped), but also can achieve the effect of promoting flowering and fruiting.
To the extent that stabbing the cortex does not hurt the xylem, the outflow of latex does not have to be wiped away. The traditional method of ring peeling, chopping wound healing is slow, encounter rainy weather is easy to rot, triggering a variety of diseases.
To make many years of fruitless pineapple honey more flowers and fruits, and does not hurt the tree, can be used to ring cuts coated with "flower king No. 2" cream way to improve the fruiting rate. Flower bud differentiation period, in the trunk of the smooth place ring cutting, coated with "Flower King 2" cream in the ring cutting mouth, it can enter the tree transmission system, activate the tree anion, a large number of plant electrons and foliar photosynthesis burst out of high-energy electronic polarity induction, impede the transport of photosynthetic products downward, resulting in the transformation of the growth function of the tree to the reproductive function, and strengthen the flower genes and the flower organ. The healthy flower genes and flower organ ovary, breeding a large number of high-quality flower buds and promote differentiation, more flowers, more fruits, carrots, stable yields and high quality for many years.
5. Planting pineapple head need to wait for the incision to dry
Planting pineapple head does not need to wait for the incision to dry, and there is no need to cut the planting.
Pineapple (scientific name: Ananas osus) is one of the famous tropical fruits. Fujian and Taiwan is called pineapple, the area of New Malaysia is called yellow pear, the mainland and Hong Kong is called pineapple. There are more than 70 varieties, one of the four famous fruits of Lingnan.
Pineapple is native to South America, Brazil, Paraguay, along the Amazon River basin, the 16th century from Brazil to China. It has now spread throughout the tropics. Its edible part is mainly composed of fleshy enlarged inflorescence axis, spirally arranged in the periphery of the flowers, flowers usually do not bear fruit, persistent perianth lobes surrounded by a cavity, the cavity hides the shriveled stamens and styles. The fibers of the leaves are very tough and can be used for fabrics, rope making, netting and papermaking.
Pineapple and pineapple are biologically the same fruit. In the market, pineapple and pineapple for different varieties of fruit: pineapple peeled after the "inner thorns" need to be removed; and pineapple eliminated after the outer skin does not have the "inner thorns", do not need to be used to cut out a groove.
6.
Bromeliad, also known as pineapple flower is the most popular indoor foliage plants, it is strange flowers, beautiful patterns, make people wonder.
Bromeliad: belongs to the bromeliad family. Mainly distributed in South America rainforest areas to rocky coastal forests.
There are epiphytic and non-epiphytic bromeliads. The leaves of the plant are richly colored, some species have longitudinal stripes or horizontal bands of interlocking colors, and some have mottled powder or downy hairs.
Bromeliads bloom almost year-round, and before and after flowering, 2-3 or more daughter plants grow from between the leaves at the base of the plant, which can be removed and planted separately after a certain amount of growth. This family of plants is light-loving, like high temperature and humidity, like good drainage, like containing humus and coarse fiber culture soil.
Suitable for planting in semi-shade and half sunny places. Bromeliad is native to Central America and the West Indies, is a perennial evergreen grass, the flower has many varieties, plant height 20-35 cm, leaf clusters tightly embraced into a funnel shape, inflorescences drawn from the center of the plant, higher than the leaf surface, beautiful and imposing, is a good flower for indoor decoration.
Bromeliads need to be trimmed off after flowering, if there is forked growth at the base of the mother plant, when the twigs are about 6 centimeters, use a sharp knife to cut them down, cuttings in the river sand, placed in a sheltered, high humidity, warm and hot environment, that will send out new roots, can be potted. Bromeliad seedlings should be potted in time, adult bromeliads about 2-3 years to change pots 1 time, cultivation soil is suitable for selection of peat, rotting leaves, river sand and other quantities of mixed and become, potted or change pots should be watered thoroughly.
Bromeliads need bright light, need 3-4 hours of direct light per day, summer temperature 20 ℃ -30 ℃, appropriate more watering, preferably more watering foliage water, winter to maintain more than 10 ℃, give water should not be too much. Bromeliad in March-October for the growing period, can be about every 20 days to apply light liquid fertilizer 1 time, bromeliad fertilization to spray foliar water or irrigation of the heart of the leaf is very effective, often liquid fertilizer irrigation in the leaf clusters, winter dormant often do not need to fertilize.
7. cut off the head of the pineapple can be planted pineapple
A, cut off the head of the pineapple can be planted pineapple, but to check the head of the pineapple leaf clusters there is no moth, gently pull the leaves, if it is very easy to ***, it proves that this pineapple is too ripe, not suitable for planting.
The planting method is as follows: Step 1: cut off a pineapple head Step 2: prepare to plant crown buds. The so-called crown buds, that is, the top part of the pineapple fruit, it is the most nutritious, so used to plant the best! Some people will acquire pineapple gear chipped off the crown buds used to plant.
To cut off the crown bud, just cut at the junction, leaving no flesh. You will see dots on the cut surface, which are root primordia from which roots will grow later.
Step 3: Rooting the Crown BudsSet the crown buds overhanging the mouth of the bottle, as close to the water as possible but avoiding contact. If they are submerged directly in the water, there is a risk of rotting.
Keep them moisturized and out of the sun during this time. Part 4: Transplant the crown buds.
When the roots have grown to 0.5cm they are ready to be transplanted into a clay pot. Always keep the soil slightly moist, but not wet (this will promote rot) and not dry.
It will take six to eight weeks for the stem to really send out strong roots. Don't rush this process and avoid watering and fertilizing diligently.
Second, note: pineapple head avoid direct light, the soil has a wide range of suitability, but should not be neutral or alkaline soil, clay or unstructured chalky sandy soil, requiring PH5-6. In the annual rainfall of more than 1,000-1,500 millimeters, and the time of precipitation is more evenly distributed (100 millimeters per month) of the place is more suitable for pineapple growth.
Groundwater level of 30-50 cm is conducive to root growth. Third, after the seedling planting survival, with 0.3% urea plus 1% potassium chloride leaching solution for 2-3 times of extra-root fertilizer; the second year in the spring and autumn each fertilizer 1 time, each time per mu of urea 15 kg, ternary compound fertilizer 10 kg, magnesium sulfate 1.5 kg, zinc sulfate 0.5 kg.
Fourth, the fruiting period when the heart of the plant "red", inflorescence differentiation and development, timely application of good pre-flowering fertilizer, per acre of rotted chicken manure 800 kg, urea 15 kg, 15 kg of potassium chloride, magnesium sulfate 1.5 kg, zinc sulfate 0.5 kg, can increase the inflorescence, increase the number of florets, increase the size of the fruit, increase yields. Fertilizer Fertilization in a timely manner after fruit picking, 500 kg of fire soil per mu, 700 kg of rotted chicken manure, 15 kg of urea, 10 kg of ternary compound fertilizer, to restore the tree's strength and promote the growth of sucking buds, so that the tree can blossom and bear fruit in the following year at the appropriate period.
Fertilize as appropriate before the arrival of low temperatures in winter, with potash as the main fertilizer, which can enhance the plant's cold resistance and reduce frost damage.
Expanded Information:
The buds used as seedlings should be fully mature. Where the leaf body becomes hard and open, about 24-36 centimeters long, peeled off the base of the leaf, now brown rootlets, that is, mature buds.
Suction bud seedlings are usually picked before and after fruit harvesting for seedling use. Plants propagated by sucker buds are stronger than other sprout seedlings, and bear fruit earlier, usually 12-16 months after planting.
The size of the sucker buds and the results of the sooner or later related to the use of larger sucker buds planted in 1 year will be able to blossom and bear fruit. 2, such as the use of too large sucker buds, planted soon after the buds will be the results of the fruit, the fruit is small, should not be used.
In order to expand the reproduction coefficient, in the mother plant sucker buds about 10-15 cm high, all of them will be removed for reproduction, and then the mother plant to apply fast-acting fertilizer 1 time, to promote the base of the buds to continue to sprout, when the second batch of sucker buds grow to the above height, such as the former method of treatment, to promote the drawing of the third batch of sucker buds sprouting. In this way, in one year, the Philippines varieties of a mother plant sprouting an average of more than 40 sucker buds, such as the need to use 30 cm high old mature seedlings, each plant can only get 6-8.
3, crown buds crown buds born at the top of the fruit, also known as the top bud. Crown buds after planting leaves more, short, dense; root points, rooting fast; fruit large, flowering neat, fruit maturity also neat.
Generally, it takes 2 years to bear fruit after planting, and inferior variants such as multiple crowns, compound crowns, and fan crown buds should be eliminated. The appropriate time to remove the crown buds is about 20 centimeters from the buds on the leaf blade hardening, the upper part of the open, the base becomes narrow (commonly known as "inserted waist scattered tail"), and there are young roots.
4, descent buds born on the fruit base or fruit stalk, also known as bracket buds. Strong descent buds after planting its growth and fruit time and yield the same as the crown buds, extra large descent buds higher yield.
For more descent buds more fruit warts buds should be eliminated, can not be allowed to reproduce. 5, descent buds occur more impact on fruit development, should be removed in batches, but for the propagation of seedlings, can be appropriate to retain 2-3 robust, to be grown to 18-20 cm when planted, planted in about 18-24 months to results, but also descent buds longitudinal slice of 2-4 slices of the seedling.
8. Why pineapple head hydroponics can grow flowers
There is a part of the plant's organs or tissues, now science and technology has a way to make it regenerate, which is called tissue culture. This is called tissue culture. Through tissue culture, a plant can grow from a small part into a plant. As for the pineapple can just put into the water and grow a new plant, it depends on the specific situation. And pineapples are cross-pollinated plants, so you need to plant several more to get fruit after flowering. If you plant just one, it's unlikely to produce pineapples.
Expanded Information:
Pineapple fruit is excellent in quality and rich in nutrients. It contains a lot of fructose, glucose, vitamin B, C, phosphorus, citric acid and protease and other substances. Per 100 grams of pineapple containing 87.1 grams of water, protein 0.5 grams, 0.1 grams of fat, 1.2 grams of fiber, 0.1 milligrams of nicotinic acid, potassium 126 milligrams of sodium 1.2 milligrams of zinc 0.08 milligrams of carbohydrates 8.5 grams of calcium 20 milligrams of phosphorus 6 milligrams of iron 0.2 milligrams of carotenoids 0.08 milligrams of thiamine 0.03 milligrams of riboflavin 0.02 milligrams of vitamin C 8 to 30 milligrams of vitamin C, phosphorus 6 milligrams of iron 0.02 milligrams of riboflavin. Vitamin C 8~30 mg, 0.3 g of ash, and contains a variety of organic acids and pineapple enzymes.
