How can Chinese chive flower be planted with high yield?

How can Chinese chive flower be planted with high yield? How should Chinese chive flowers be managed after planting? Also ask experienced netizens to help introduce the leek flower, also known as the leek flower, which refers to the white flower cluster on the white leek in autumn. it is a kind of seasoning commonly eaten in the urban and rural areas of the north and south of our country. generally, the leek flower is picked when it is about to bloom, ground and pickled into a sauce to eat. Eating leek flowers has the effect of promoting appetite and promoting digestion. At the same time, leek flowers are rich in calcium, phosphorus, iron, carotene, riboflavin, ascorbic acid and other healthy ingredients. Therefore, the farming network has sorted out the planting techniques and management methods of leek flowers, which are listed in detail below for netizens' reference. 1. Planting techniques of Chinese chive flowers: 1. Time of sowing and raising seedlings of Chinese chive flowers: Chinese chive flowers can be propagated by two methods: seed and ramet, which can be sowed or propagated every year. At present, seed sowing and propagation are the main methods in our province, and it is suitable to sow and raise seedlings in October. 2. Disinfection method of leek flower seeds: before sowing, soak the seeds in 1000 times potassium permanganate solution for 4 hours, pick them up and rinse them with clean water, then soak them in clean water for 48 hours, remove them and put them in a cloth bag or container and cover them with cloth. Put them in a place of 20 ℃ for budding. During the budding period, it should be washed with clean water twice a day, and 20% of the seeds can be sown after 3 days. 3. Selection and treatment of seedling land for Chinese chive flower: the slightly acidic sandy loam with convenient drainage and irrigation, water and fertilizer conservation should be selected for planting Chinese chive flower. The plot which is not spring onion and garlic in the previous crop is used as seedbed, and the sowing amount per mu is 4 kg. Before sowing, the nursery bed was sunburned and carefully prepared, combined with soil preparation and applied appropriate amount of mature organic fertilizer, calcium magnesium phosphate fertilizer and plant ash. The seedbed with many weeds can be sprayed with butachlor 2 days before sowing. 4. Methods of seedling, sowing and management of leek flower: the sterilized leek seeds were evenly sown on the border surface, then covered with a thin layer of soil, the thickness of the soil should be uniform, cover the border surface with sunshade net, and water thoroughly after sowing. After the seeds are germinated and unearthed, open the sunshade net. Management should be strengthened at the seedling stage to achieve frequent watering, thin fertilization, early weeding and early disease prevention, so as to facilitate early seedling emergence, seedling emergence and strong seedling emergence. 5. The treatment of the transplanting site of Chinese chive flowers: the loam with deep soil layer, rich organic matter, loose and fertile soil and convenient drainage and irrigation should be selected for planting Chinese chive flowers. Deep ploughing was carried out before planting. 2000 kg of mature organic fertilizer and 50 kg of calcium magnesium phosphate fertilizer were applied per mu. After fully mixing the base fertilizer and soil, the bed was leveled with a width of 1.5m and a height of 30cm. Combined with soil preparation, 2 kg Milol granules per mu were applied to prevent underground pests such as leek maggots from biting the roots. 6. Transplanting time and method of leek flower: it can be planted when the seedling age of leek flower reaches about 50 days, the seedling height is about 20 cm and there are 4 leaves. For seedlings pulled out of the seedbed, the roots and leaves should be cut off before planting. 3 seedlings were planted in each hole, 4 rows in each row, the row spacing was 40 cm × 30 cm, and 360 000 trees per mu were transplanted, and the root water was drenched after transplanting. Second, the management of planting leek flowers: 1. Leek flowers need a large amount of fertilizer because of the long harvest period, and they are fertilizer-tolerant vegetables, timely and sufficient nutrient supply can make the plant grow strong; when there is not enough fertilizer and water, it is easy to senescence early, and the flower stem becomes small. 2. In the period of vigorous vegetative growth in winter and spring after chive flower planting, topdressing should be done in time to cultivate sturdy rhizomes and leaves and increase tillers. After planting, topdressing is usually done every 10 days or so, and 15kg compound fertilizer is applied every 5m / mu. 3. When the Chinese chive flower enters the harvest period, attention should be paid to the rational application of nitrogen, phosphorus and potassium fertilizer, and more organic fertilizer should be applied, including 200 kg per mu of organic fertilizer and 15 kg of compound fertilizer, which can be combined with ploughing and weeding for topdressing. 4. Chinese chive flowers should keep the soil moist during the whole growing period. Long-term drought will reduce tillers, shorten leaves and bolts, and affect yield. Therefore, the water should be watered in time during drought, and the water can also be diverted to the ditch for infiltration irrigation, but the water level of the ditch should be more than 25 cm lower than the border surface. 5, if rainfall should pay attention to timely drainage and waterlogging prevention, if it is under serious flooding for a long time, it will cause root rot, leaf yellowing, sharp reduction of tillers, and serious plant death. Pay attention to weeding and soil cultivation, transplant plants at the right time, and alternate use of pesticides in the prevention and control of diseases and insect pests.
