Mung bean has strong adaptability, resistance to drought, drought, tolerance, and delay, and the following techniques should be adopted for the production of autumn mung beans:
1. Choose a variety. Autumn mung beans should be selected with short growth period, high yield and good quality, and the maturity period should be controlled within 90 days. "E-Green No. 1" and "E-Green No. 3" can be selected.
2, timely broadcast early. Autumn mung beans can be planted before and after the beginning of autumn, but the earlier the sowing, the longer the flowering and podding time, the higher the yield, the timely land preparation and early sowing after the water is removed.
3. Reasonable close planting. Mung bean shade can be set with autumn corn. Single planting should be broadcast or on demand. The row spacing is 15-17 cm × 40-50 cm, the acre is 1.5-2 kg, and the density is 8000-10000. Seedlings are planted early after emergence.
4. Add fertilizer. Although mung beans are legume crops, it is necessary to increase the fertilizer production for the high yield of autumn mung beans. In particular, attention should be paid to top dressing from emergence to flowering to promote nodule formation. Generally, 20 kg of phosphate fertilizer is applied to the acre, 12.5 kg of potassium fertilizer is used as the base fertilizer, and 2.5 kg of urea is used as the seed fertilizer. In the seedling stage and the early flowering stage, the seedlings are promoted and controlled, and the flowering period is good.
5, pay attention to grass shortage. The mung bean field grassland is usually heavier, and it is necessary to combine the cultivating and weeding to remove the weeds in time.
6, prevent pests and diseases. Mung beans are more harmful to leaf spot, pea pods and buds. Leaf spot disease can be sprayed with 3% leafhopper powder 1.5-2 kg per mu, or 2-25 ml with 25% enemy killing emulsion, or 25% insecticidal double 250 g with water 50 kg. Bean pods can be controlled with 6000 times enemy killing solution or 1000 times killing solution in the pod stage. Aphids can be controlled with 40% dimethoate 1500 solution.
7, timely harvest. Mung bean pods are prone to violent seed, and should be harvested in batches to reduce losses.
