The growth process of mung bean has three stages: seed initiation, sprouting and leaf extraction.

Mung beans are temperature-loving, with suitable temperatures for emergence and growth ranging from 15 to 18 degrees Celsius, and requiring higher temperatures during the reproductive period. Germination starts at 8 to 12 degrees Celsius. During flowering and podding, the temperature is generally 18 to 20 degrees Celsius is the most suitable. Higher temperatures and excessive stem and leaf growth will affect flowering and podding. Mung beans are not frost tolerant in the later stages of reproduction, and when the temperature drops below 0 degrees Celsius, the plants will freeze to death and the germination rate of the seeds will be low.

Cultivation techniques:

Because the mung bean is a dicotyledonous crop, cotyledons out of the soil, seedlings topsoil ability is weak, if the soil is stagnant or too much bumpy soil, prone to cause lack of seedlings broken or uneven emergence of the phenomenon. Therefore, before sowing, require deep plowing and fine harrowing, fine ground preparation, harrowing soil bumps, so that the soil is loose, water retention and moisture conservation, to prevent the soil from knotting, on the virtual reality, in order to facilitate the implementation of seedling rotation stubble.

The principle of fertilization of mung bean, should be based on organic fertilizer, inorganic fertilizer, organic fertilizer and organic fertilizer mixed use; adequate basal fertilizer, appropriate fertilizer policy. Fertilizer technology: mung bean's short reproductive period, barrenness, its root system and *** raw nitrogen fixation capacity, production often do not fertilize, but in order to improve the middle and low production plot of mung bean yield, should be increased fertilizer.

Generally mu seed fertilizer diammonium phosphate or nitrogen, phosphorus, potassium compound fertilizer about 10 kg. Mung bean fertilizer is best in the flowering period combined with sealing together. Each hectare can be chased with ammonium nitrate, urea and other nitrogen fertilizers 40-60 kg, potassium sulfate 100-120 kg.
