Abstract:Insects grow quickly and are hardly controlled when grains are stored in the area of high temperature and high humidity. Nitrogen filling technology can effectively control the resistant pest and solve the cross-contamination problems to ensure the storage safety of grain. It was found that using nitrogen filling technology can kill all cryptolestes ferrugineus with killing rate of 100%. In addition, it is a new development direction for green storage of grain. Application of the gas-controlled storage technology can reduce chemicals usage amount, avoid environment pollution and increase fumigation-free rate and food safety.
