Cultivation techniques of buckwheat

Buckwheat (also known as black wheat, flower wheat or Triticum triticum) has a short growth period, usually only 70-80 days, and has strong adaptability, so it is an ideal replanting crop after the disaster. The main points of planting techniques: buckwheat preparation is not strict on soil conditions, regardless of sandy loam, light loam, acid soil, slightly alkaline soil and newly reclaimed land, can be planted. Deep ploughing and fine raking are required before sowing to loosen the soil. Fertilizing buckwheat is a crop that needs more fertilizer. Every 100 kg buckwheat needs to absorb 3.3 kg of nitrogen, 1.5 kg of phosphorus pentoxide and 4.3 kg of potassium oxide. In addition, according to the study, buckwheat root system has a strong ability to absorb phosphorus and potassium fertilizer, especially for insoluble phosphate fertilizer, has a special utilization ability, the application of phosphorus and potassium fertilizer can significantly increase buckwheat yield; nitrogen fertilizer should not be applied more, otherwise it is easy to lodge. The base fertilizer is mainly barnyard manure, phosphate fertilizer and plant ash, and appropriate topdressing during the growing period. Before sowing, select large and full seeds and dry them in order to promote post-ripening and improve germination energy and germination rate. The sowing rate is 2kg / mu, and the sowing time can be extended to the middle and late July. Sowing methods include sowing, on-demand sowing and strip sowing, with row spacing of 35 cm to 50 cm and sowing depth of 3 cm to 4 cm. When the soil is dry, it can be deepened to 5 cm to 6 cm. After management and sowing, suppress according to soil moisture, hoe and kill grass after emergence to prevent water evaporation; combine soil cultivation and topdressing before flowering to carry out the second intertillage. The flowering period of harvested buckwheat is very long, the seed ripening is very inconsistent, and the grain is easy to fall off, so the suitable harvest time is very important; generally, when most plants have 2 + 3 fruits turn brown, it is the suitable harvest time. Harvest time is best chosen in the morning when the dew is not dry, and pay attention to light cutting and light handling, in order to reduce the loss of falling grains. If you encounter frost damage or windy weather before harvest, you should seize the harvest. Click to get more buckwheat planting techniques click to get more food crop planting techniques
