Essentials of cultivation of buckwheat with minor grains

Buckwheat, also known as black wheat, flower wheat or triangular wheat, has strong adaptability, the growth period is very short, generally only 70-80 days; it has high nutritional value and contains a variety of amino acids and vitamins. It plays a special role in prevention and health care of hypertension, coronary heart disease, diabetes, cancer and other diseases. Key points of cultivation: soil preparation. Buckwheat is not strict on soil conditions, no matter sandy loam, light loam, acidic soil, slightly alkaline soil and newly reclaimed land, can be planted. Deep ploughing and fine raking are required before sowing to loosen the soil. Fertilize. 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. Sow seeds. 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. The sowing methods are sowing, on-demand and strip sowing, and strip sowing is better. Administration and Management. After 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. Harvest. The flowering period of buckwheat is very long, the seed maturity is very inconsistent, and the seeds are easy to fall off, so the appropriate harvest is very important; generally, when 2/3 of the fruits of most plants turn brown, it is the appropriate 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
