1. Fine land preparation
Because mung bean is a dicotyledonous crop, the cotyledons are unearthed, and the seedlings' top soil ability is weak. If the soil is compacted or there is too much soil, it is easy to cause lack of seedlings or ridges or uneven seedlings. Therefore, before planting, deep ploughing and fine rake are required, the ground is finely prepared, and the soil is raked to make the soil loose, store water and preserve moisture, prevent soil compaction, virtual upper and lower solid, in order to facilitate the emergence of seedlings.
2. Choose good varieties
The selection of good varieties is an effective measure to increase production. Appropriate varieties should be selected according to local natural conditions, soil fertility and commodity value. At present, in the production of mung bean in our province, there are more than 20 varieties planted, which can be described as many, chaotic, and mixed, and there is no main plant variety. However, the varieties with better performance in production include Liaolu 6, Liaoyin Mungdou 1, Zhonglu 2 and so on.
3. Use the correct seeding technique
Because the growth period of mung beans is relatively short, and the suitable sowing period is long, it can be sown in spring or summer. Spring sowing in our city should be in mid-May, and summer sowing should be before July 5. There are three methods for sowing mung beans: drill seeding, hole seeding, and sowing. But it is more to drill. Drilling should prevent the soil from being too deep, the seeding is too thick and the seeding is missed. After the emergence of seedlings, it is found that there is a phenomenon of lack of seedlings and broken seedlings, and the replanting should be completed within 7 days. The row spacing is mostly 0.5～0.6m, and the plant spacing is 10～20cm. The appropriate seeding depth is 3～5cm. The planting rate per mu is generally 1.5 to 2.0 kg per mu.
4. Carry out reasonable close planting
Because the output of mung bean is composed of three parts: the total number of pods per unit, the number of grains per pod, and the grain weight. The yield is very closely related to the planting density. Therefore, the planting density of mung beans should be determined with the characteristics of the variety and soil fertility. In general, the principles of early-maturing varieties are dense, late-maturing varieties are sparse; erect type is dense, semi-vine type is sparse, and vine type is sparse; fertile land should be thin, lean land should be dense; early seeding is thin, late seeding is dense. Upright varieties, the plants develop vertically, suitable for close planting, with 8,000 to 15,000 seedlings per acre. Semi-vine varieties are erect at the base, creeping at the middle, upper or top, and should be thinner, leaving 7000 to 12000 seedlings per mu. The vine planting plants should develop horizontally and should be sparse, and the density should be 6000-10000 plants per mu. In high-fertility soil, about 8000 seedlings per mu; 8000 to 12000 seedlings in medium-fertile soil; 13000 to 15000 seedlings in barren land.
5. Scientific fertilization
The principle of fertilization for mung beans should be based on organic fertilizers, supplemented by inorganic fertilizers, and mixed use of organic fertilizers and organic fertilizers; applying sufficient base fertilizer and proper topdressing. Fertilization technology: Mung bean has a short growth period, strong barren tolerance, and its root system has the ability of symbiotic nitrogen fixation. Fertilization is often not applied in production. However, in order to increase the yield of mung bean in medium and low-yield plots, more fertilizer should be applied. Generally, about 10kg of diammonium phosphate or nitrogen, phosphorus, and potassium compound fertilizer is applied per mu. In poor soil fertility, without basal fertilizer and seed fertilizer, after the first compound leaf of mung bean is unfolded, combined with field tillage, 3kg of urea per mu, or 8-10kg of compound fertilizer can be used. It has obvious effect of increasing production. In the plots with higher fertility, the seedling stage should be controlled, and topdressing should not be carried out. Too much nitrogen fertilizer will cause excessive vegetative growth, stalks and leaves spreading, field shading, plant lodging, serious flower and pod falling, and reduced mung bean Yield.
6. Carry out field management
In order to ensure that the mung bean grows neatly in the seedling stage, the population is well developed, more buds, more flowers and more fruit, large pods and large grains, high yield and high quality, the following points should be done after sowing: (1), depending on the situation, suppression: the seeding moisture Unfavorable plots should be suppressed in time, followed by the seeds, so that the seeds are in close contact with the soil, increase the surface moisture, promote the germination and development of the seeds, and emerge early and full seedlings. (2) Check and replenish seedlings in time: after the emergence of mung bean seedlings, it is found that there is lack of seedlings and broken ridges, and replanting should be completed within 7 days. (3) Set seedlings with time: In order to make the seedlings develop well, the seedlings should be thinned after the first compound leaf is unfolded, and the seedlings should be fixed after the second compound leaf is unfolded. Remove weak seedlings, diseased seedlings, small seedlings, mixed seedlings and weeds at the set density, and leave strong seedlings. The practice of single-plant seedling retention is conducive to the healthy growth of plants. (4) Timely intertillage and weeding: not only can eliminate weeds, but also break soil compaction and loose soil, reduce evaporation, increase ground temperature, and promote nodule activity. This is a measure to increase mung bean production. Generally, after the first compound leaf of mung bean is unfolded, combined with the first shallow hoeing of thinning; after the second compound leaf is unfolded, the seedlings are fixed and the second middle tillage is carried out; the third deep middle tillage is carried out at the branching stage, and Root and soil cultivation should be carried out, and intertillage should be carried out until the ridge is closed. In cultivating depth, the principle of shallow-deep-shallow should be mastered. (5) Timely irrigation and drainage to prevent waterlogging: Mung beans are crops that require a lot of water but are not tolerant of waterlogging and are afraid of flooding. The seedling stage of mung bean is more resistant to drought and requires less water; the flowering and pod stage is the peak of water demand. At this time, in case of drought, water should be filled in time. But mung beans are also afraid of waterlogging and flooding. Excessive water in the seedling stage will aggravate root diseases and cause rotted roots and dead seedlings. In the later period, the plants suffered from waterlogging, the plant growth was poor, premature senescence occurred, the flowers and pods fell off, and the yield decreased. Therefore, mung beans should be drained to prevent stains during the rainy season.
7. Implement scientific planting methods, do a good job in efficient planting, and increase production and income
Take advantage of the short growth period of mung beans, insensitivity to light, shade tolerance, long sowing period, root nodules nitrogen fixation and fertilization, plant mung beans in the next crop of wheat and other crops, vegetables, and melons, or combine with high-stalk crops. Intercropping or mixing crops with slower growth in the early stage, such as corn, cotton, sweet potato, yellow tobacco, etc., make full use of natural resources such as light, temperature, water, and soil per unit of land area to harvest more in one place, which will increase production and income. Feed the land.
8. Implement crop rotation
Avoid continuous cropping of mung beans. Because continuous cropping has many diseases and insect pests, poor quality, and inhibits the growth of rhizobia due to the reproduction of harmful microorganisms, there is a saying in farmers that "bean fields are adjusted every year and the yield is high every year." At the same time, mung bean is also an important crop for fertile land, and is an excellent first crop for cereals. Therefore, for mung bean planting, the land should be arranged reasonably, and the crop rotation should be implemented. It is generally better to be separated from cereal crops such as corn, sorghum, and wheat by 2 to 3 years.
