PH_3+5%CO_2用于高仓熏蒸研究

FUMIGATION WITH PH_3 MIXED 5%CONCENTRATION CO_2 IN LARGE WAREHOUSE

在重庆铜梁国库进行了PH3+ 5 %CO2 膜下环流熏蒸杀虫试验。试验结果表明 :在AlP用量相同的条件下 ,加入 5 %的CO2 可提高同期的PH3浓度和CT值 ,确保杀虫效果。

Recirculation fumigation with PH 3 mixed 5% concentration of carbon dioxide under film was tested.The results showed that at the same dosage of ALP,mixed with 5% concentration of carbon dioxide can raise the concentration of PH 3 and CT in the same period,and ensure the effect of controlling stored grain insects.After fumigation,no PH 3 residue was found.
