Strain technique of fertilization in mung bean

In order to obtain a better yield of mung bean, the suitable fertilization period and the suggested amount of fertilizer for mung bean were put forward. That is, in the early flowering stage of mung bean (the maximum effect period of fertilizer), it is better to apply nitrogen and phosphorus combined application, applying nitrogen and phosphorus compound fertilizer 10kg / mu, or spraying 1.5 kg urea and 1 kg potassium dihydrogen phosphate per mu, divided into 2 times. 0.5-1.0 kg urea and 400 kg 500 g potassium dihydrogen phosphate each time, 60-65 kg water was sprayed. Because for every 100kg mung bean seed, it needs to absorb 9.68kg of nitrogen, 2.93kg of phosphorus (P2O5) and 3.51kg of potassium (K2O). Except for nitrogen, which comes from the atmosphere, the rest of the nutrients are absorbed from the soil. The vegetative growth stage of mung bean is from emergence to flowering, and from flowering to bulging is the stage of both vegetative growth and reproductive growth, which is not only the vigorous growth period of the plant, but also the key period to determine the grain yield and quality.
