摘要

To effectively control the stored grain pests, the technology of phosphine re-circulation under plastic sheet for grain fumigation by placing aluminium phosphide (AlP) in airducts was researched. First, the aluminum phosphide tablet was placed in air-ducts,then reacted with moisture in the atmosphere and released phosphine. Meanwhile, phosphine was blown into grain bed by the circulation fan. In this way, the phosphine dispersed and distributed uniformly throughout the grain in the warehouse. All stages of stored grain pests were controlled by an effective concentration of phosphine held for enough time. In fact, this technology was the combination of "phosphine re-circulation fumigation under plastic sheeting" and "placing AlP at air-duct", which has many advantages, such as flexible and safe operations, functional, economical, reduced pollution to grain.
