High-yielding cultivation techniques of autumn buckwheat

Buckwheat is rich in a variety of minerals and vitamins and has unique nutritional value. it has become a new generation of coarse grain green nutrition and health food, and it is a kind of food crop with high nutritional value and medical value. Focus on the following six techniques: 1. Select high-yielding varieties. The improved varieties of buckwheat, West Buckwheat No. 1 and West Buckwheat No. 2, were mainly promoted. 2. Timely early sowing and mixed sowing. The Beginning of Autumn-the End of Heat should sow seeds no later than the end of August at the latest. Dry the seeds for 1 day before sowing, soak the seeds in 40 ℃ warm water for 10 minutes, then sow the seeds, strip sowing or evenly sowing and cover the shallow soil. Buckwheat is a cross-pollinated crop. Mixed sowing of 2-3 fine varieties can prolong the period of flowering and pollination, improve the hybridization rate and seed plumpness, and help to increase yield. The State Drug Administration issued an early warning for the consumption of poisonous mushrooms. 3. Increase the application of phosphorus and potassium fertilizer. The growth period of buckwheat is relatively short, so we should re-apply base fertilizer and increase phosphorus and potassium fertilizer in fertilization methods. Based on base fertilizer, 1000 kg of pig manure, 15 kg of phosphate fertilizer and 30 kg of plant ash are applied per mu. 4. Early management. Drought resistance and drainage to ensure that the whole seedling is strong. After the seedling was fixed, 5ml / mu of urea was applied as seedling fertilizer, and the main sequence growing point was removed during budding, and the branches spread at the tip. Artificial pollination was carried out for 2 or 3 times during flowering period to promote fruiting and increase yield. 5. prevention and control of diseases and insect pests. Pay attention to the prevention and control of diseases and insect pests such as blight, ring disease, brown spot and white mildew, overeating armyworm and meadow borer. 6. harvest at the right time. You can get a harvest when you do medium well.
