Selecting improved varieties
Selecting improved varieties is an effective measure for increasing yields. Suitable varieties should be chosen according to local natural conditions, soil fertility and market value. Correct sowing technique
Because mung beans have a short growth period and a long suitable sowing window, they can be sown in spring or summer. Spring sowing should be in mid-May, and summer sowing should be before July 5. There are three sowing methods for mung beans: drilling, hole sowing and broadcasting. Drilling is the most common. With drilling, avoid covering the seed too deeply, sowing too densely and missing spots. After emergence, if gaps or missing plants are found, reseeding must be completed within 7 days.
Because mung bean yield is made up of three parts - the total number of pods per unit area, the number of seeds per pod and seed weight - yield is very closely related to planting density. Therefore, mung bean planting density should be determined by variety characteristics and soil fertility. In general, the principles are: dense for early-maturing varieties, sparse for late-maturing varieties; dense for upright types, sparse for semi-vining types, and even sparser for vining types; sparse on fertile land, dense on poor land; sparse for early sowing, dense for late sowing.
The fertilization principle for mung beans should be organic fertilizer as the main source, inorganic fertilizer as a supplement, and mixed use of organic and inorganic fertilizers; the policy is to apply sufficient base fertilizer and topdress appropriately. Fertilization technique: mung beans have a short growth period and strong tolerance to poor soil, and their root system also has symbiotic nitrogen-fixing ability, so fertilizer is often not applied in production. However, to increase mung bean yields on medium- and low-yield plots, fertilizer should be applied. Generally, about 10 kg per mu of seed fertilizer diammonium phosphate or nitrogen, phosphorus and potassium compound fertilizer is applied. On poor hill land with poor soil fertility where no base fertilizer or seed fertilizer is applied, after the first compound leaf of the mung bean unfolds, together with cultivating, 3 kg per mu of urea, or 8-10 kg of compound fertilizer, can be topdressed. Practice crop rotation and stubble changing
Mung beans should not be continuously cropped. Continuous cropping leads to more pests and diseases, poor quality, and the reproduction of harmful microorganisms that inhibits the development of rhizobia. There is a farming saying: "Change the bean field every year, and the yield rises every year." At the same time, mung beans are also an important soil-enriching crop and an excellent preceding crop for cereals. Therefore, when planting mung beans, land should be arranged reasonably, with crop rotation and stubble changing, preferably rotating with cereal crops such as corn (2324,4.00,0.17%), sorghum and wheat, generally with an interval of 2-3 years.
