Direct seeding cultivation techniques of mung bean in summer

Mung bean is one of the important minor cereal crops, which integrates nutritional value and medicinal diet value. with the improvement of people's living standard, the demand for mung bean is more and more, which makes the price of mung bean rising continuously, while planting mung bean has less investment, quick effect and high benefit. The development prospect is very broad, its high-yield and high-quality cultivation techniques are as follows: first, selection and soil preparation. The selection of excellent varieties is the key to improve the yield of mung bean. Early and middle maturing varieties such as Lulu 1 should be selected, such as compact plant shape, strong main stem, strong branching ability, lodging resistance, disease and insect resistance, high quality and high yield. The stubble should be killed as soon as possible after wheat harvest, and 1500-2000 kg of organic fertilizer per mu was applied. Second, broadcast as soon as possible. The earlier the summer sowing mung bean, the higher the yield. The best sowing time in our region is the first and middle June, the sowing amount is 1.5-2 kg per mu, the sowing depth is 3-5 cm, and the row spacing is 40-50 cm. Third, field management. The growth period of mung bean is short, and the word "early" is highlighted in field management. First, the seedlings are fixed in the morning, and the seedlings can be fixed when the second compound leaf appears, with a distance of 10-15 cm and leaving 1-12000 seedlings. The growing season of summer mung bean is the period before drought and then waterlogging. therefore, when selecting land and preparing land, it must be irrigated by drought and waterlogged, especially when sowing, when the weather is dry, it is necessary to create soil moisture before sowing. Appropriate amount of nitrogen fertilizer can be applied at seedling stage, applying 7.5-10 kg urea per mu to promote plant health. Mung bean is easy to grow weeds during the growth period, and weeding should be carried out before the first compound leaf, the second compound leaf and the budding of branches. Fourth, prevention and control of diseases and pests. When aphids and pod borer damage occurs, 40% omethoate 800-1000 times should be used for spray control. Fifth, harvest at the right time. When mung bean pods mature and turn black, they can be harvested by stages if possible. If explosive pods are harvested in batches, they can also be harvested at one time when 80% of the pods turn black.
