The amaranth flower is also called éŸèŠ±, which refers to the white flower clusters born in the autumn éŸ white, how can the leeks grow high yield? For this reason, Hui Nong.com compiled the planting techniques and management methods of leeks, and listed them in detail. The majority of growers have reference. First, the cultivation technology of chives: 1. Seeding time of amaranth planting: The amaranth flower can be bred by two methods: seed and ramets. At present, seed sowing and breeding are the mainstays in our province, and seeding in October is appropriate. 2. Disinfection method of amaranth seed: Before seeding, immerse the seed in 800-1000 times solution of potassium permanganate for 4 hours, pick up and wash with water, then soak it in water for 24-48 hours, remove it and put it into the bag. Or cover the container with a cloth and place it at 20 °C for germination. It should be washed twice a day with water during germination, and 20% of seeds can be sown after 2-3 days. 3. Selection and treatment of amaranth seedlings: The planting of amaranth should be selected from the micro-acidic sandy loam where irrigation and drainage are convenient, water-preserving and fertilizer-preserving. The former is not a planting bed of onion and garlic, and the seeding amount per mu of seedbed is 4 kg. Before sowing, the seedbed is turned over and finely grounded, and the appropriate amount of decomposed organic fertilizer, calcium magnesium phosphate fertilizer and grass ash is applied in combination with the preparation of the ground. The weed bed with more weeds can be sprayed with butachlor for 2 days before sowing. 4. Sowing and management methods of amaranth seedlings: Spread the dried amaranth seeds evenly on the noodles, then cover a layer of thin soil, the thickness of the covering soil should be uniform, cover the kneading surface with a sunshade net, and pour water after sowing. After the seeds are germinated and unearthed, the shade net is uncovered. In the seedling stage, it is necessary to strengthen management, so that watering, thin fertilization, early weeding and early disease prevention can be used to facilitate early emergence, emergence of seedlings and emergence of seedlings. 5. Treatment of the transplanting place of amaranth: The planting of amaranth should be carried out in a loam with deep soil, rich organic matter, loose and fertile, and convenient irrigation and drainage. Deeply turn before planting, apply 2000 kg of decomposed organic fertilizer per acre, 50 kg of calcium, magnesium and phosphate fertilizers, mix the base fertilizer and soil thoroughly, and level the ridge. The width of the raft is 1.5 m wide and the height is 30 cm. 2 kg of Miller granules are applied per acre in combination with the soil preparation to prevent underground pests from biting the roots. 6. Time and method of transplanting amaranth: When the seedling age of the amaranth flower is about 50 days, the height of the seedling is about 20 cm and 3-4 leaves can be planted. The seedlings that are pulled from the seedbed should be cut off a part of the roots and leaves before planting. 2-3 seedlings were planted at each hole, 4 rows per seedling, the row spacing was 40 cm × 30 cm, 3600-4000 holes were transplanted per acre, and the root water was drenched after transplantation. Second, the management points of planting chives: 1. Amaranth flower requires a large amount of fertilizer due to its long growth period, and it is a fertilizer-tolerant vegetable. The nutrient supply in a timely and sufficient manner can make the plant grow robustly; when the fertilizer is insufficient, it is easy to prematurely decay, and the flower stem becomes fine. 2, in the winter and spring after the establishment of leeks and flowers in the strong growth period, it is necessary to topdress in time to cultivate the roots and leaves thick and increase the tiller. After planting, the fertilizer is usually applied once every 7-10 days, and 5-15 kg of compound fertilizer is applied per acre. 3. When the leek flower enters the harvesting period, attention should be paid to the rational application of NPK fertilizer. It is advisable to apply organic fertilizer, apply 200-500 kg of organic fertilizer per acre and 10-15 kg of compound fertilizer, and combine topdressing and weeding to carry out topdressing. 4, the amaranth should keep the soil moist throughout the growing season, long-term drought will reduce tillering, leaves and flower buds shrink, affecting yield. Therefore, water should be watered in time when it is dry, or water can be diverted to the ditch for seepage irrigation, but the water level of the ditch should be lower than 25 cm above the surface. 5, such as rainfall should pay attention to timely drainage and flood control, such as long-term exposure to severe flooding, will cause root rot, yellow leaves, sharply reduced tillering, causing plant death in severe cases. Pay attention to weeding and weeding, and transplant the soil at appropriate time. Pay attention to the alternate rotation of pesticides when controlling pests and diseases.

It is a type of phospholipid, which is a molecule that is composed of two fatty acids, a phosphate group, and a nitrogen-containing base.
