据专家预测,PH_3是目前和以后一定时期内防治储藏物害虫的主要熏蒸剂,甚至不可能用其它熏蒸剂替代,因此延长PH_3使用寿命,提高和改进AlP的使用技术,将是一项战略性工作。利用探管熏蒸,可以提高熏蒸剂的钻透性和扩散性,但也存在着AlP分解时间太长、不易完全分解、管壁结露等缺陷。为解决探管在使用中存在的这些问题,我
According to the experts’ prediction, PH_3 is the main fumigant for the control of stored pests at present and in the future, and it is even impossible to replace it with other fumigants. Therefore, extending the PH_3 service life and improving and improving the use of AlP will be a strategic jobs. The use of probe fumigation can improve the permeability and diffusivity of fumigants, but there are also defects such as AlP decomposition time is too long, not easy to completely decompose, condensation on the wall. To solve these problems in the use of the probe, I
