The high yield of mung bean also requires the application of good fertilizer. In the past, the reason why the yield was not high was that mungbeans had rhizobia and they could be absorbed and used by the fixed nitrogen. Little application of fertilizer was a misconception. Mung bean is very sensitive to phosphate fertilizer. Increasing phosphorus fertilizer can promote the healthy growth of seedlings, increase branching and scarring rate, and increase yield. Basal fertilizer is mainly farmyard manure, generally 2500-3000 kg of fertilizer per acre, 20-25 kg of superphosphate, and appropriate amount of potash fertilizer, evenly applied to the plot to be sown, in order to ensure the entire growth and development stage of phosphorus and potassium nutrition. Demand. Mungbean seedling root growth is underdeveloped, Rhizobium bacteria incomplete nitrogen fixation, absorption of nutrients is limited, to obtain high yield must be timely application of Miao Fei, usually topdressing urea 3 ~ 4 kg per mu, in order to promote the healthy growth of seedlings. In the flowering and poding period, spraying with potassium dihydrogen phosphate and boron fertilizer for 1 or 2 times can achieve the effect of increasing grain growth.
