First, the variety selection Different varieties are used according to the habits and consumption habits of different season varieties. In winter and early spring, red leeks and safflower varieties with strong cold resistance are used. In other seasons, it is resistant to pests and diseases, red cabbage and whole green amaranth. Generally, from late February to late March, it is advisable to use early-maturing and cold-tolerant varieties of sharp-leaved red rice bran and sharp-leaved red glutinous rice. From the beginning of April to the end of May, it is advisable to choose red sorghum, Dahongpao, white rice bran, and willow stalk. From the first half of June to the beginning of August, the summer and autumn cultivation should use more heat-resistant white rice bran, willow stalk, red sorghum and other varieties. Second, the cultivation season Amaranth can be cultivated from spring to autumn without frost. Open field cultivation can be planted from late March to early August; and greenhouses and small arch sheds can be planted for early 20 to 30 days, that is, planting begins in late February, and can be carried out for about 30 days in the morning. In addition to early spring cultivation, it is generally available in about 35 days after sowing. Third, cultivation techniques Soaking seeds and germination Amaranth seeds are soaked in cold water for 24 hours, and need to be washed several times during soaking to facilitate water absorption. In the winter and early spring, the soaked seeds are taken out, washed with water, removed and drained, wrapped in gauze with good permeability, covered with a wet towel, and germinated at 15-20 °C. When 30% - 50% of the seeds are white, they can be sown. Other seasons are cultivated by direct sowing. 2. Planting on the ground It is advisable to choose plots with less weeds. The soil requirements of leek are not strict, but the soil is loose, fertile, fertilizer-preserving and water-retaining. It applies 5000 kg of decomposed organic fertilizer per acre, 50 kg of 25% compound fertilizer, and intensive cultivation. It is made into a sorghum with a width of 1 - 1.2 meters, a groove width of 0.3 meters, and a groove depth of 0.15 - 0.2 meters. Seeds of sowing amaranth are small, and sowing with some fine sand or fine soil can make the seeding even. The amount of seed per acre is 0.25-0.5 kg. It can be spread or broadcasted in a flat manner. The four-toothed scorpion can be used for shallow or sloppy (damp seasons with heavy rain). The stalker can be slightly deeper in spring, shallower in summer, shallowly covered with soil, and then repressed, watering, waiting for emergence . In the winter and early spring, a thin layer of straw is moisturized, and then covered with a layer of film insulation, the greenhouse is covered and the temperature is raised. Cover the sunscreen in summer. 3. Field management Temperature management In winter and early spring, the mulch and covering are uncovered after watering. After watering, a small arch shed is built in the greenhouse to facilitate heat preservation. When the outside temperature is low, a layer of straw curtain is added to the shed in the evening. After the emergence of the summer, cover the sunscreen in time, take the early cover and expose it. Fertilizer management should keep the soil moist in winter and early spring. Watering should be done with small water, try to choose watering in the sunny morning, and apply a 0.2% urea aqueous solution after the seedlings, and then apply it once every 7-10 days. Promote growth. Appropriately increase the amount of water in the summer, usually watering in the morning and evening. In addition to the application of the base fertilizer, it is necessary to carry out multiple topdressing. Generally, when the seedlings have 2 true leaves, the first fat is chased. After 10-12 days, the second fat is chased, and after each harvest, the topdressing is performed once. The type of fertilizer is mainly nitrogen fertilizer, and each time per mu, there can be 1500-2000 kg of thin human excrement urine and 5-10 kg of urea. Weeding and timely manual weeding. After the sowing, about 7-10 days after emergence, the weeds should be taken before and after emergence, and the stalkers can carry out inter-row cultivating and weeding. 4. Pest control Agricultural control uses high-quality (cold) disease-resistant varieties, rational layout, rotation with other crops or rice in a certain period of time, clean the pastoral, reduce the number of pests and diseases, cultivate strong seedlings, improve resistance, increase organic fertilizer, balance Fertilize and apply less fertilizer. Spray foliar fertilizer (such as Golly) in bad weather. Physical control uses yellow plates to trap aphids, black light to trap moths. Biological control uses natural enemies to deal with pests, select pesticides with low lethality against natural enemies, and create an environment conducive to the survival of natural enemies. Antibiotics (agricultural streptomycin, etc.) are used to control diseases (soft rot). Disclaimer: Some articles on this website are transferred from the Internet.
