摘要
使用一种PH3发生器。PH3气体由发生器出气孔经毒气导管送入通风地槽，借助气流使PH3气体自下而上在粮堆中均匀扩散和分布，以杀死害虫。结果表明，熏蒸10天后未发现活虫与螨类，成虫试点死亡率100％，1个月后仅在一死角发现锈赤扁谷盗1头／kg。
A PH3 generator was used in the trial. PH3 Ras was piped into underground aeration passage and diffused and distributed eveniv with the aid of the air flow from the bottom to the top in grain bulk. The results showed that no live insects and mites were found,the motality of adults was 100% after 10 days. Only 1 insect/kg of Cryptolestes ferrugineus was found after 1 month
