When the amount of mung beans is small, aluminum phosphide can be put into a small cloth bag, put into mung beans, and sealed in a bucket for preservation. If the amount of storage is large, the ratio of 1 to 2 pieces of aluminum phosphide per cubic meter of storage space can be stored in a sealed warehouse or in a fumigation chamber.
