High-yield cultivation techniques of mung bean

1. Selection of land. Mung bean has strong adaptability and is not strict with the soil requirements. It is often used for intercropping with corn, sorghum, cotton, sweet potato, sesame, millet, etc. It can also be planted in fields and gaps. Mung beans avoid continuous cropping because of continuous pests and diseases, poor quality, harmful microorganisms will inhibit the development of rhizobia. Mung bean is also an important fertilizer crop, and it is a good frontier for cereals. Therefore, it is best to work with cereal crops such as corn, sorghum, and wheat dumplings. It is not appropriate to use Chinese cabbage as a forehead, and it is generally 2-3 years apart.

2. Site preparation. Since mung bean is a dicotyledon crop, the cotyledon is unearthed, and the top soil of the seedlings is weak. If the soil compaction or soil waste is too much, it may easily cause the phenomenon of lack of seedlings and ridges or emergence of seedlings. Therefore, before sowing, it requires deep plowing, fine soil preparation, and leveling of soil and soil to make the soil loose, store water and protect soil, and apply emptiness to prevent soil compaction to facilitate emergence.

3. Use fine varieties. The varieties with large size, thin skin, low solid content, good cooking, softness, taste, and high yield performance are selected, such as Zhonglv No.1, Zhonglu No.2, No.2 Green Green, and No.2 Green Green.

4. Suitable sowing. Spring sowing in late April to mid-May, summer sowing in late June. Mung bean is warm, the suitable temperature for emergence and growth is 15°C-18°C, and a higher temperature is required during the growth period. The germination begins at 8°C-12°C. During the flowering and podging, the temperature is generally 18°C-20°C. The temperature is too high and the stems and leaves grow too vigorously, which will affect flowering and scarring. Mungbeans are not tolerant to frost in later growth stages, and temperatures fall below 0°C. Plants will freeze to death and the seed germination rate will be low. Therefore, the summer sowing mung bean must pay attention to timely sowing in order to normal maturation before the onset of cryogenic morning frost. The sowing rate of mu is generally 1.5-2 kg and the seeding depth is 3-5 cm.

5. Reasonably dense planting. The planting density of mung bean should be determined by the variety characteristics and soil fertility. Generally should grasp the early maturing varieties of dense, late-maturing varieties of rare; upright dense, semi-wild type thin, creeping type more dilute; fertility should be thin, thin to close; early species dilute, late species density principle. Mung bean generally early maturing varieties, low water and fertilizer plots suitable density of 180,000 -200,000, 11-15 strains per meter rice seedlings; medium-maturing varieties, moderate water and fertilizer conditions suitable density of 150,000 -170,000, per meter Seedlings 8-10 strains; late-maturing varieties, high water and fertilizer conditions suitable density should be 120,000 - 140,000, 7-8 seedlings per meter.
