In recent years, the cultivation area of ​​buckwheat has grown a lot, and the market price has been rising, and it has been sold at home and abroad. The whole body of buckwheat is a treasure. It is rich in nutrients and can be used as a variety of supplementary foods that people in urban and rural areas love. With the adjustment of the industrial structure in rural areas, the development of commodity production and the improvement of people’s living standards, buckwheat will become a good non-staple food. Therefore, the development of buckwheat production has broad prospects, but buckwheat production is not high in production. How to make a new breakthrough in the output of buckwheat? First, the selection of earthworms in the field is not suitable for continuous cropping. Buckwheat is a straight-rooted crop, roots are not well developed, and the buds are soft. Therefore, sowing should be carried out before sowing, fine soil preparation, water conservation, to create good environmental conditions for the preservation of seedlings. Second, the seed treatment 1. Selection of species to increase the yield of buckwheat should be selected seed, seed coat, seed size uniform new species. To eliminate seeds that are yellow and cannot germinate or have low germination rates. It is best to use the fine varieties of No.9 and No.10 of Jijing, and use the farm varieties as collocation varieties, and we must eliminate the farm varieties. 2. Seed soaking in warm water at 35°C for 15 minutes can increase the germination rate. 3. The first seed dressing is to take 1-5 kilograms of ash in the water immersed for 1-2 days, spray the seeds with vegetation ash liquid one day before sowing, 10 kilograms of seed ash sprinkle 1 kg. And mix the residue of plant and wood ash in the seed and mix well. After 3-4 hours, the seeds can be planted without agglomeration and can increase the yield. The second is to use 40% pentachloronitrobenzene 0.5 kg mixed seeds 50 kg, can prevent blight, ringworm disease, brown spot and white mold. Third, increasing fertilization material buckwheat is very sensitive to fertilizer reactions, especially like fertilizer. For every 50 kilograms of seed produced, 1.65 kilograms of pure nitrogen, 0.95 kilograms of phosphorus, and 2.15 kilograms of potassium should be drawn from the soil. Thus Mushi circle manure not less than 1000 kg, 80 kg of plant ash. It should be noted that although buckwheat is good for potash fertilizer, potassium chloride cannot be used because chlorine ions can cause leaf spot disease and lead to reduced yields. Mushi and 20 kg of urea and 6 kg of urea are used as base fertilizers, which are both economical and increase yield. Fourth, timely sowing of buckwheat sex hi cold and moist, warm hi flowering, flowering and wet. According to this physiology, the principle of "Autumn Blasting before the Fall" is mastered for the local climate and the best sowing date is selected. The general sowing in late June and early July is more appropriate. Fifth, rational close planting of buckwheat sown with too thin and dense will affect the yield. The production experiment proves that it is advisable to increase the seeding volume by 3.5-4 kilograms per hectare, and cover 141 thousand-160,000 acres per mu. The depth of sowing is 3-4 cm, and the thickness of earth covering is generally 3 cm. It is more difficult to unearth more than 3 cm. After sowing, if the soil is dry, it can be pressed again with wooden rakes; if the soil is wet, use a horse-drawn pole to drag it. Sixth, management management First, we must promptly loosen the soil, promote growth and development, seedlings during the three leaves, so that the distribution of seedlings evenly. When the seedlings are 9-10 cm in height, they are cultivated once every 10 days until the budding stage is closed. During the initial flowering period, 0.3% potassium dihydrogen phosphate solution and 0.1% ammonium molybdate or boric acid solution were sprayed. Full artificial pollination at flowering time is suitable from 8 to 10 am. The method is to use a rope or a wooden rod to laterally move the plants 2-3 times, every 3 days. Conditional farmers will store two boxes of bees for every 15 mu during the flowering period. Occurrence of pest control in time, the armyworm, grasshopper and hook moth can be used 90% crystal trichlorfon 1000-2000 times spray. Aphids were sprayed with 40% dimethoate 1500-2000 times. Seventh, pay attention to the appropriate period of harvest buckwheat flowering period of up to 30-35 days, 25-35 days after flowering to form seeds. Strong drop, generally loss of 20-40%. Because the time of planting and planting is different, sooner or later, maturation is not neat. Therefore, it cannot be harvested when the whole plant matures. Generally, more than 70% mature in the lower part, and there is still a small amount of flowers in the upper part that are suitable for harvesting. Pay attention to the observation and timely harvest. The best time to get it is on rainy days or in humid mornings until 11 a.m. Source: Rural Economic Information
