Mung bean preferred seed retention technology

Mungbean is a common miscellaneous grain, and the market demand is large, but the variety is miscellaneous and the quality is poor. Doing a good job in the retention of mung bean can not only increase the output, but also ensure the quality of mung bean production, and the economic benefits are high, which is worth promoting in all regions. When mungbeans are reserved, they must select good varieties with strong resistance, or excellent local varieties. Timely sowing, strengthen management mung bean is a short-day warm temperature crops, the minimum temperature of seed germination can not be lower than 8 °C, the optimum temperature is 25 °C, therefore, sowing should not be too early, slightly later than field crops, generally May 15 The most suitable sowing is on the 25th. In order to meet the demand for nutrients during the whole growth period of mung bean, in addition to the application of base fertilizer, it is also necessary to top-dress fertilizer in time to prevent falling flowers and plants, and to prevent and treat diseases and insect pests in time. Two listing methods are selected in the field. Two selections are made according to the typical traits of the original variety. The first time the mungbean is in the flowering and poding stage, the traits of the mung bean will be strong and healthy, the plant shape will be good, the knot will be moderate, and it will collapse. Excellent single plants with strong resistance to pests and diseases are listed; for the second time, within three days before mung bean maturation, on the basis of the first selection, selections for maturity, high yield, lodging resistance, resistance to stress, and resistance to blasting are carried out. Select single plant listings. The selected excellent plants were harvested in time and transported to a dry and ventilated place for 2 days after threshing, with the exception of net impurities and bagged for preservation. • In the case where there is not much seed to be used in a single selection method, within 4 days before Mungbeans mature, in the fields with high yield traits, choose plants that are robust, moderate branching and fruiting, high seed setting rate, the same maturity, and full grain. Anti-loft, anti-fried, resistant to pests and diseases, with the characteristics of the original species of the excellent single plant listing, bundled after harvesting in a dry and ventilated place to dry for 2 days, and then threshing, removal of impurities packed in a single, for the species Use, this method is more time-saving, labor-saving. • Since the mungbean pods are easy to explode after ripening, they must be harvested in time, and the signs must be carefully checked at the time of harvest. The signs are unclear or incomplete and cannot be mixed to ensure purity. During the preservation of seeds, we must pay attention to moisture, heat, pests and rodents, and constantly check to ensure the quality of the seeds.
