Technical points of replanting buckwheat

The growth period of buckwheat is short, and it can mature in 80 days. The key points of high-yield cultivation techniques of autumn buckwheat are as follows: 1. Fine soil preparation. The unearthing ability of buckwheat seedlings is weak, so we should pay attention to fine soil preparation and create an environment conducive to the growth and development of buckwheat seedlings. 2. High quality sowing. Buckwheat the Beginning of Autumn before and after sowing, buckwheat can be planted everywhere before the summer, sowing 3.5kg per mu. You can't use interannual vintage. Before sowing, the seeds can be soaked in 40 ℃ lukewarm water for 15 minutes before sowing, which has a significant effect on early emergence and strong seedlings. 3. Apply fertilizer skillfully. Buckwheat growth period is short, should be based on base fertilizer, so as to apply sufficient base fertilizer, early topdressing fertilizer, suitable phosphate fertilizer and potash fertilizer. Topdressing depends on the application of seedlings, not too much or too late, so as not to delay flowering and fruiting and lodging in the later stage. Extra-root topdressing with potassium dihydrogen phosphate or trace elements such as boron, molybdenum and manganese at flowering stage can obviously increase yield. 4. Scientific management. When the seedling height is 7Mel 10 cm, it is combined with weeding and time seedlings, and the second tillage is combined with soil cultivation to promote the development of adventitious roots. Weeding must be completed before flowering. 5. Pay attention to drought resistance and drainage.
