Apply sufficient base fertilizer to mung bean
Although mung bean rhizobium has the ability of nitrogen fixation, the application of farm fertilizer and phosphorus and potassium fertilizer can obviously increase the yield. Before sowing, 2500 kg of farm manure, 20 kg of phosphate fertilizer and 1 kg of biological potash fertilizer were applied as base fertilizer per mu. For example, in the field where it is too late to apply base fertilizer, 7.5 kg of ternary compound fertilizer is applied per mu in the early stage of growth, that is, the branching and early flowering stage, in order to enhance the nitrogen fixation ability of rhizobium and increase flower bud differentiation.

Mung bean from emergence to flowering and sealing line, to adhere to diligent ploughing and weeding, generally not less than 4 times, mid-ploughing depth from shallow.

In case the seedlings are weak. Excessive humidity is one of the important causes of stunting disease, so the appropriate humidity should be controlled at seedling stage. Irrigation before sowing should be appropriate, too large, high humidity, and lower soil temperature; too small, the seedling stage to increase the number of watering, not only labor-consuming, but also increase humidity. In the early stage of seedling emergence, fine soil can be sprinkled on the bed.
