Buckwheat as a nutritious, health-care crops, more and more favored by people. It has a short growth cycle, adaptability. In the stubble land and early potato planting, you can get good economic benefits. Fine ground preparation of buckwheat seedlings poor surface soil capacity, root development is weak, high requirements for ground preparation, so first pay attention to the link of plowing and ground preparation. Buckwheat short growing period, 667 square meters (1 mu) should be additional phosphorus and potash fertilizer 8 to 10 kg and well-rotted organic fertilizer as a base fertilizer.

The timely sowing of buckwheat like warm and cool, afraid of frost, sowing too early and too late will affect the yield. The first crop harvested in a timely manner after the ground, at the end of July or early August sowing. Sowing method to sow the main, can also be used sow sow. Sowing depth of 3 to 4 cm, seeding volume of 667 square meters 4 kg. Variety of buckwheat, plant height of 60 to 70 cm, growing period of 70 to 80 days. Before sowing, first in the sun for 2 to 3 days, then soak the seeds in warm broth and select the seeds.

Buckwheat varieties are used after summer crops and before winter crops, in the middle of the shorter growing season, or as a replacement crop after a disaster. Although the requirements of the previous crop is not strict, but leguminous and cultivated crops are suitable, can increase the yield of 15% to 30%. Buckwheat grows rapidly in the seedling stage, and covering the ground with stems and leaves prevents evaporation of soil moisture and inhibits weed reproduction. It is also a good crop rotation starter crop. Buckwheat growing period is short, generally 60-80 days to maturity, fertilization should follow the "full base fertilizer, early top fertilizer, appropriate application of phosphorus and potassium fertilizer" principle.

Mu 850-1000 kg of farmyard manure, calcium superphosphate 15-30 kg as a base fertilizer, seeding should be appropriate application of bone meal, grass ash, chicken manure and other phosphorus and potassium fertilizer, because the buckwheat root system can secrete organic acids, not easy to dissolve the phosphorus fertilizer has a special ability to absorb. 3-4 months of the true-leaf period of the seedling is weak, 15-30 kg of seedling urea per acre, the first flowering of the first acre of available potassium dihydrogen phosphate 0.15-0.2 kg, 0.5-1 kg of urea to 60-75 kg of water sprayed 2-3 times to ensure adequate supply of nutrients, reduce buds and flowers, and improve the seed set rate.
