Mung bean sowing has a high elasticity and is a good relief crop. In the area along the Huaihe River at the latest till late August, the practice of replanting seeds after years of disasters proves that replanting mungbean is one of the best options for reclaiming flooded areas along the Huai River. The cultivation techniques are as follows: 1. Selection of varieties. The available varieties are Zhonglv No. 4, Zhonglv No. 6, Minglv No. 3, Yulv No. 4, Yulv No. 5, Yulv No. 6 and Zhenglv No. 7. The growth period of these varieties is short, generally 55 - 60 days, good quality, high yield, up to 125-175 kilograms per mu, high-yielding fields can break 200 kilograms. 2, Shizuji Fei. Mungbean rhizobium has nitrogen-fixing ability, but increasing manure and phosphorus and potassium fertilizers have obvious effect on yield increase. Before the planting, 2,500 kg of farmyard manure, 20 kg of phosphate fertilizer and 1 kg of biological potash were used as base fertilizer per acre. If it is too late to Shiji Fei field, in the early stage of growth, that is, branching, beginning flowering period, top dressing compound fertilizer per acre 7.5 kilograms, in order to enhance the ability of rhizobial bacteria to fix nitrogen and increase flower bud differentiation. 3, early sowing when the rush, a reasonable dense planting. We must base ourselves on seeding and planting seedlings in order to increase production. The effective accumulated temperature of mung bean from sowing to harvesting is 1500-1600°C. The accumulative accumulated temperature in the province from August to October is mostly above 1600 days, which can fully meet its growth and development needs. Taking into account the late Tengqi autumn species, grabs along the Huaihe River in the south of the area are planted at the end of July and the beginning of August, and sowing will be completed by August 10th at the latest. The blocks with relatively late water withdrawal can be exposed first, followed by water rushing sowing, and then soaked again before sowing. The whole scorpion has a width of 2 meters and a good four-channel rake. On-demand hole spacing 40 cm 13-16 cm, 2-3 seeds per hole (remove hard seeds), per acre seeding amount 1.5-2 kg; sowing field or sowing delay field, seeding amount per acre can increase by 0.5 -1 kg. The sowing depth should be 3-4 cm. 4, field management. When mung bean seedlings reach 2 leaves and 1 heart, the seedlings are removed. When four leaves are seedlings, the spacing is 13-16 centimeters, the spacing is about 40 centimeters, and 1-1.5 million seedlings are planted per acre, and the planting time can be up to 20,000. Mung beans from the emergence to the flower seal line, we must adhere to the intensive cultivation and weeding, generally not less than 4 times, cultivating depth from shallow to deep, and then from deep to shallow. Mung bean flowering and podging stage is the peak period of fertilizer and water, in the flowering season, applying 4-5 kilograms of urea per acre, in order to increase the rate of pod formation. Potassium dihydrogen phosphate is sprayed at the beginning of Chengyu to promote full grain filling. If drought is encountered at this time, it should be watered in time to keep the soil moist. In case of rainy weather, it must be drained in time to ensure the normal growth of mung bean. Replanting mung bean after flooding is often overgrown with weeds and heavy pests. During the growing season, we must adhere to the combination of chemical prevention and agricultural control, and focus on prevention of weeds. Second, we should do a good job of prevention and control of pests such as Spodoptera litura and soybean mealworms. 5, timely harvest. The fields that need to be plucked in time for the autumn crops can be ripened around e.g. on October 15 when the local average temperature is above 15°C. Due to inconsistent maturation of mung bean, harvesting in stages can reduce losses and ensure high yields. Before harvesting, the beans were exposed to insecticides after the harvest, and the fumigation of the mung bean was performed after the storage.
