Mung bean, also known as green beans, is named after its greenish-green color. It has been cultivated in China for more than two thousand years. Because it is rich in nutrients and has many uses, Li Shizhen called it "a good dish in the dish." However, despite its nutrient-rich and well-loved people, the storage of green beans is a headache. Because the original mung bean was not properly preserved, it is vulnerable to mung bean harm. Mung bean also known as "bean beef", it breeds rapidly, extremely destructive power, great harm to mung bean, so the key to safe storage of mung bean is to eliminate mung beans. The reporter interviewed Gao Xiaoli, a doctor and associate professor of Crop Cultivation and Tillage at the Agriculture College of Northwest Agriculture and Forestry University. She gave some suggestions on how to kill mung bean in mung bean in winter. Low temperature treatment Using natural winter cryogenic larvae to kill larvae After selecting the cool and cold weather after the strong cold wave transited, the green beans were spread on the cement field into a thin layer of about 6-7 cm thick, flipped once every 3-4 hours, and covered with a 1.5-meter-high shed cloth at night. To prevent frost, it is conducive to radiation cooling, after 5 days and nights, remove the frozen body and impurities, cold storage, close the doors and windows, you can achieve the purpose of freezing dead larvae. Use a refrigerator, freezer or cold storage to kill insects After the mung bean is placed in a cloth bag, the bag is tightly closed and placed in a freezer. The temperature is controlled below -10°C, and the larvae can be frozen and chilled after 24 hours. This method can also be used for other beans. Pharmaceutical treatment Aluminum phosphide treatment When the temperature is 25°C, 1 m3 of mung beans are treated with aluminum phosphide and fumigated under confined conditions for 3 to 5 days. Then they are exposed to sunlight for 2 days and filled with wheat bran, pressed and sealed tightly for 15 days. The pest control rate can reach 98%-100%, and the best control effect is achieved. This can kill insects and kill eggs without affecting the activity and consumption of mung bean germs. Be sure to seal tightly to ensure that the place is dry. The alcohol fumigation is poured into a small cup with one or two alcohols. The small cup is put into the mung bean barrel and sealed. After 1 week, the alcohol evaporates and the small insects can be killed. Dichlorvos fumigation Put dichlorvos in the vial, seal it with gauze, place it on the surface of mung beans, seal the mung bean for 5-7 days, remove the dichlorvos bottle, and seal it. This method kills more than 95%. For every 100 kilograms of green beans stored, use 80% of 10 millilitres of dichlorvos EC. In the storage of mung beans after pest control, Gao Xiaoli particularly emphasized that after the mung bean is disinfested, it must be isolated and stored, and the warehouse should be sealed so as to prevent the oviposition of foreign insects from causing oviposition again.
