When is the grass head planted and can be eaten? Generally divided into spring sowing, summer sowing and autumn sowing. Which month to plant depends on where you come from, mainly for the first year to plant alfalfa safely through the winter. I belong to North China, and I usually plant it from the end of May to the beginning of July. The first alfalfa crop generally needs a growth period of 50 days, the second crop needs a growth period of 35 days, and the third crop needs a growth period of 35 days. Each crop can generally float up and down for 5 days, and the growth period of the last crop is generally 20-30 days after harvest. After turning green, it can grow when the daily average temperature reaches 5℃.
How many months can I plant ginger? Ginger is usually sown from late April to early May, and it is suitable for low-heat valley areas in early and middle March. Those that have germinated or cultivated with plastic film can be advanced appropriately, but not necessarily now. Ginger is available all year round.
The harvest of old ginger is generally carried out in the middle and late June from 65438+ 10 to June 165438+ 10. When the local plants begin to wither and the roots are completely swollen and mature, ginger is harvested. At this time, the harvested ginger slices have high yield, strong spicy taste and storage resistance.

The garden should be planted in the best month before and after Qingming, with flowers and trees.
The best month for planting lotus ginger is sowing in the middle of March, and the seedling stage is180 ~ 220 d. The plant spacing on the planting ditch is 60~70cm, and the underground stems are laid flat on it, with the buds facing upwards, and the seedlings are 2.7× 104~3.3× 104 plants /hm2. After covering the soil, the stems are poured with 3.0× 104kg/hm2 fertilizer.
Poplar is best planted in spring and autumn.
Poplar cutting seedling raising techniques are as follows:
1, choose a good variety. The key to the benefit of seedling raising is to choose an excellent new fast-growing poplar variety.
2. Choose nursery land. The key to the success or failure of seedling raising lies in the selection of seedling raising place. The nursery should be a place with flat terrain, good irrigation and drainage conditions, fertile and loose soil and convenient transportation. Before winter, we should deeply plough 25-30 cm of frozen plastic film, apply 3000 kg of base fertilizer per mu, and prepare the border soil in the next spring.
3. cut and cut. This is the basis for determining the growth of seedlings. The stubble seedlings of 1 year should be selected, and the branches with no pests and diseases and strong growth should be selected as cuttings. Cutting diameter 1-2.5cm, length 15 to 18cm, preferably with 3-5 robust buds. Manual cutting should choose a sharp kitchen knife, the upper incision should be even, and the lower incision should be horseshoe-shaped, so as to avoid the incision from cracking. Cut cuttings should be stored immediately to avoid air drying and water loss and reduce the survival rate.
Step 4 cut. Poplar cuttings can be used in spring and autumn. But it should be early spring now, and the cuttings should be cut with 60 cm row spacing. The cuttings form a 45-degree angle with the ground, exposing 1-2 buds, with 4 cuttings per meter and 4,800 cuttings per 667 square meters. It is forbidden to insert cuttings backwards. Cut cuttings with different thicknesses to make them grow evenly.
5. Fertilizer and water management. It is the guarantee of seedling growth. Immediately after cutting, water is poured for the first time by small water injection method. Water once a week, and then water after the seedlings are fixed in the first half of May. After that, check the soil moisture every ten days and a half months before watering. Generally, topdressing is done twice in June and July. Water about 10 times throughout the year. Watering for the last time in early September, stopping irrigation, promoting lignification of seedlings, preventing seedlings from growing white, is conducive to overwintering. 6, weeding and picking buds. You can't loosen the soil and weed until the seedlings are fixed. Generally, weeding and loosening the soil can be done for 2-3 times. Almost every axil of poplar leaves can produce lateral branches. So get rid of the buds in time. During the whole growing period, pick flower buds at least three times. 1 The time is in the middle and late May. In principle, only one strong seedling is left for any two or more plants. The second time, at the end of June, all sprouted lateral branches were erased. The third time was in the middle and late July.
7. Control pests and diseases. When preparing soil before seedling, mix fine soil with 50% ethion granule 1.5-2kg and spread it on the nursery to prevent underground pests. Before transplanting seedlings, soaking the seed roots 1 ~ 2 hours with a mixture of 50% carbendazim and 15% thiophanate methyl at a ratio of 200 ~ 250 times of1∶1can effectively control root rot and black spot. After the cuttings germinate, spraying 50% methamidophos 1200 times liquid base can effectively prevent the buds from being bitten. In the early July and early August of the growing season, 50% phoxim 1500 times solution and 500 times solution of carbendazim were used to control pests such as poison thorn moth and poplar brown spot respectively.
When is the best time to plant pumpkins? Pumpkin has the characteristics of strong cold tolerance and low temperature growth, and can be cultivated in winter and early spring, early spring and open field in spring and autumn. Off-season cultivation in winter and spring should be covered with plastic film and multi-layer insulation facilities. In early spring, small arch shed can be used for cultivation. Try to use insect-proof nets in the early stage of autumn cultivation, and cover them with plastic film for insulation in the later stage. Different cultivation methods are adopted in different cultivation seasons. Taking early spring cultivation in North China as an example, it is briefly described as follows:
(1) Seedling raising is carried out in North China, and pumpkin seedling raising in early spring is carried out in sunlight greenhouse or sunlight bed, and the seedling raising period is generally in the middle of March. (2) Soaking the seeds to accelerate germination, scalding the seeds with hot water at 100℃ for 5 seconds, immediately cooling the cold water to 30℃, and soaking the seeds for 4-6 hours. Between them/among them
Wash the seeds with warm water at 30℃ for 2-3 times to remove the mucus on the surface of the seeds. Take out the seeds and dry them for 2 hours, and accelerate germination after the surface of the seeds is dry. When accelerating germination, the temperature is kept at 28 ~ 30℃ for about 36 hours, and the radicle of the seed is exposed, commonly known as exposure to the sun, and the seed can be sown.
(3) sowing? Seedling raising with 56-hole seedling tray. Before loading, mix 2 kg of 40% carbendazim powder with 1 m3 seedling substrate for disinfection. Spray the seedling substrate with clear water to make its water content reach 70%. When filling the seedling substrate, there is a space of 2 cm at the cup mouth. Sow 1 germinated seed in each seedling cup, cover with 2 cm thick expanded vermiculite, and then cover the seedling tray tightly with plastic film. You can also use the methods of accelerating germination and direct seeding in the field. The sowing date in North China is mid-April, that is, seedlings can emerge after the local late frost.
(4) After seedling management, the temperature was kept at 25 ~ 30℃ during the day and 65438 08℃ at night. When 60% of the seeds are arched, they are removed.
The plastic film is cooled to 20 ~ 25℃ during the day and to 12 ~ 15℃ at night to prevent the seedlings from growing white. When the leaves grow to 2 cm, they are white.
The temperature is maintained at 25 ~ 28℃ during the day and around 65438 05℃ at night. Spray clean water every 5 days during seedling raising. When the seedling has two leaves and 1 heart,
Planting with seedling substrate. ?
(5) Soil preparation, fertilization and planting should be deeply ploughed and aired before and after winter, which can not only weather the soil, but also eliminate some underground pests. Water should be done 10- 15 days before planting. Pumpkin has a well-developed root system and needs a lot of fertilizer, so it needs to be applied with base fertilizer again. Generally, 3000 kg of fully decomposed chicken manure, 150 kg of cake fertilizer, 50 kg of diammonium phosphate and 25 kg of potassium sulfate are applied every 667M2, half of which is applied with base fertilizer and the other half is applied into planting ditch. Ditches are 2m apart, 0.6m wide and 0.5m deep. When digging ditches, separate the upper raw soil from the lower cooked soil; when backfilling, mix the cooked soil and fertilizer evenly and fill them in the ditch bottom, and then fill the raw soil and rake it flat. Then make the ditch into a ridge with a width of 0.8 meters and a height of 0.2 meters.
It is best to grow bamboo in Baoji for several months. Can I plant them all year round? Bamboo likes a warm and humid climate, and the planting place is generally chosen in the leeward and sunny place, such as the sunny side of rockeries, hills or artificial islands. Generally, choose fertile and moist loam with good drainage and ventilation for transplanting to avoid being too sticky or sandy. The soil is slightly acidic or neutral.
Soil preparation should be carried out before planting, and the quality of planting land directly affects the quality of bamboo and the speed of forest formation. The comprehensive soil preparation method is adopted for soil preparation, that is, the planting land is thoroughly ploughed to a depth of about 50 cm. In order to ensure the growth of coarse bamboo, base fertilizer can be applied, and compound fertilizer of nitrogen, phosphorus and potassium can be selected, with 25 grams per square meter. At the same time, in order to ensure the growth of bamboo whip, some peat soil was applied.
The depth of planting holes for planting bamboo is generally 40 ~ 50cm, and the diameter of holes is larger than the root diameter of mother bamboo 10 cm. Due to the irregular growth of bamboo whips, it is impossible to dig multiple planting holes with traditional spacing, but it can be cultivated in a random and natural way.
Bamboo in early garden should be planted shallowly, not deeply. When placing the mother bamboo, make the surface of the root disk about 5 cm below the surface of the planting hole, and then backfill the soil. When filling the soil, hold the bamboo, keep the bamboo pole upright, and then step on the soil. In order to prevent bamboo from leaning or lodging due to wind or watering, some fixing devices can be installed. In order to ensure the safe overwintering of newly planted bamboos, a windbreak barrier should be erected in the northwest of bamboos in the northern region before winter, and bamboos can only be removed after 2-3 years of adaptation.
Bamboo likes fat. Persisting in fertilization is the key measure to ensure that bamboo forests grow thick and thick every year. Generally, apply fertilizer 1-2 times a year, once before bamboo shoots appear in early spring and once again in autumn and September. The application of organic fertilizer or nitrogen, phosphorus and potassium compound fertilizer specially made for bamboo can be applied in holes or spread, and the effect of hole application is the best, and the amount of fertilization at one time should not be too much, with a per square meter100 ~150g. After that, it will be applied again in September every year, and the dosage is 250 grams per square meter.
Bamboo likes to be wet, so keep the soil moist often after planting, especially when the bamboo shoots are coming out soon. After the mother plant is planted, it should be watered for the first time, that is, "fixed root water", and it must be watered enough. After the water in the planting hole permeates, it is necessary to fill the soil. After the mother plant is planted, it is usually watered for the second time in 2 ~ 3 days. At the same time, check whether the bamboo is inclined and straighten it in time so as not to affect the ornamental effect. A week later, start watering for the third time.
From April to May, the weather in the north is very dry. Besides flooding with water pipes, drip irrigation can also be used to make water fully penetrate into the soil. In June, Hsinchu entered the high growth period and needed a lot of water. When the rainy season comes in July and August, you can water it as appropriate. From September to June,165438+1October, bamboo should not be watered loosely to ensure the growth of bamboo whips and lay the foundation for the growth of big bamboo shoots and pregnant bamboo in the next year.
