Because rice has no husk protection, nutrients are directly exposed and sensitive to external influences of temperature, humidity, and oxygen. Pests and pathogens are easy to harm directly, and they are easily hygroscopic, heat, moldy, gray, aging, insects, or explosive. Before loading the rice, the inside of the container is first ignited, dried, and sterilized with paper, and during the summer and rainy seasons to prevent moisture from becoming moldy and insects, a few slices of crab shell or turtle shell or garlic head can be placed in the rice container. If the worms should be cleared first, then pepper and fennel should be wrapped with gauze and placed on the surface of the rice. The rice cylinders (barrels) should not be covered immediately; for example, if the rice has grayed out, use water for scouring and boiling for a while before cooking. A small amount of peanut oil was cooked with rice and musty. Grain stores, grain stores rice, can use low oxygen, low temperature sealed storage, mold, insects. Before the end of summer, the rice is sealed on six sides with a 0.1 mm thick polyethylene plastic film, and 3 grams of aluminum phosphide (tablets) per 5000 kg of rice can be safely used for summer.
