Through years of experience in collecting and storing grain, the author introduced to the farmers a food storage method that is safe, economical, and good to maintain the inherent quality of grain, and that is simple and easy: Zinc phosphide and vinegar are used to prevent stored grain pests. This technology is established through the slow reaction of zinc phosphide and vinegar in a confined state to produce phosphine poisonous gas causing the death of pests. This subject has passed the technical appraisal organized by the Zaozhuang City Science and Technology Commission and obtained the city's scientific and technological progress. Awards. The specific approach is: 1. Choose containers with good sealing properties such as pottery, self-made granaries, and oysters. Must be tight inside and outside, must not have gaps, holes and other breathable places, or affect the fumigation effect. 2, food and container mouth to maintain a distance of 5 to 10 cm, 2 kg of zinc phosphide per 1000 kg of raw grain, 80 grams of vinegar. The vinegar is used as a reactor in bowls, teacups, etc., placed in the grain, the mouth of the reactor is flush with the grain surface, and the zinc phosphide is wrapped in a vinegar solution with a soft paper that is breathable and absorbent. 3. Containers for foods should be immediately sealed with plastic film. The container mouth should be wiped with some paste or glue, and then tied with a string to achieve sealing. 4, after a week of deflation 1 to 2 days, and then sealed Sheng container, long-term preservation can be. The drug residue is buried deep underground. Experiments have shown that farmers using this method will not cause harm to humans and animals, and it is an economically effective, safe and reliable method of storing grain.
