Guangdong's bean vegetables mainly include kidney beans, kidney beans (bean pods), sweet peas, and Dutch beans. Beans are rich in nutrients, rich in protein, carbohydrates, vitamins and minerals, and have high economic value. Legumes are stored and transported at high temperatures. The respiratory intensity is very high. The grains in the soybean meal grow rapidly. The degree of fibrosis of the soybean meal increases and ages, and the quality is reduced. In severe cases, the food value is lost, so the beans are difficult to keep fresh vegetables. The use of low-temperature storage, generally only 2 to 3 weeks storage, non-refrigerated conditions can only be stored within 1 week. 1. Harvesting of legumes and vegetables harvested in a proper period should be carried out before the seeds have been fully developed. When the grains in soybean meal are fully developed, the soybean meal becomes fibrosis and becomes tough and cannot be used for storage. In harvesting shipments, damage to the pods should be minimized, especially the tip of the pods. Do not damage the left inflorescence or young pods when harvesting cowpeas. Second, pre-cooling and packaging harvested soybean meal should be removed as soon as possible field heat, reduce respiratory effects, post-harvest immediately into the pre-cold or cold storage, so that the temperature of beans down to about 10 °C, and in the pre-cooling storage within the selection, classification, Baskets (bags). The beans and beans can be packed in plastic baskets or corrugated cartons. Each basket (box) can be loaded to 3/4 of the capacity. The upper part of the basket is covered with a layer of kraft paper, which is then moved into a storage tray and covered with a plastic sheet. Sweet peas and Dutch beans are added. Multi-purpose foam cream packaging or use of polyethylene film bag small package for spontaneous air-conditioning storage. Third, storage and transportation of beans and vegetables storage temperature requirements 7 ~ 10 °C, relative humidity 85% ~ 90%, bean storage requirements at higher humidity (90% ~ 95%) is not easy to wither, but it can not be too high, Otherwise it will cause serious rot. During storage and transportation, excessive temperature fluctuations should be avoided. Cowpea and kidney beans are less susceptible to chilling than 6°C storage and higher than 14°C, they are rapidly fibrotic. When transporting legumes, it is best to cool them with a refrigerated truck or on the top of the truck and around the outside of the box to keep the temperature as low as possible at about 10°C. When using controlled atmosphere storage, the carbon dioxide concentration is 1% to 2%, and the oxygen concentration is 6% to 10%. China Agricultural Network Editor
