Partial Pest Fumigation Technology Research for Grain Piles

摘要

Partial pest fumigation technology for grain piles has always been a very complicated problem, by using exploring tube for dosage administration,with cloth bags of aluminum phosphide buried together and by means of the pipes for partial dosage administration to kill pests. However, it never covers all the fumigation vacancies, and solves uneven gas concentration problems. Through years of practice and contrast, we find that the recirculation fumigation method fixed with fumigation tubes is the most effective in the areas of pest infestation.
