当磷化铝和水或空气中的水份作用后就放出PH_3.根据其分布情况,PH_3比空气稍重.不论在稻谷仓库还是在密闭的空仓中,PH_3向底部沉.在密闭空仓中,PH_3在水平方向的分布是均匀的.在台湾,有几种方法适宜用于稻谷的贮藏.一种常用的方法是在仓库里对稻谷打探管,深4米.把磷化铝片放在稻谷探管的不同深度,以防治仓库害虫.每吨稻谷用5片磷化铝,把磷化铝片放在粮面以下,1和2米的地方结果其防治效果为100%.当把磷化铝片放在4米深的地方,则大多数PH_3停留在
When aluminum phosphide and water or water in the air after the release of PH_3. According to its distribution, PH_3 slightly heavier than the air. Whether in the paddy warehouse or in a closed empty position, PH_3 sink to the bottom. In a closed empty space, PH_3 In the horizontal direction, the distribution is uniform. In Taiwan, there are several methods that are suitable for the storage of rice. One common method is to probe the rice in the warehouse at a depth of 4 meters. Place the aluminum phosphide on the rice The depth of the tube to prevent storage pests.Every ton of paddy with 5 pieces of aluminum phosphide, the aluminum plate on the surface of the grain below 1 and 2 meters of the results of its control effect of 100% .When the aluminum phosphide Placed in a 4-meter-deep place, most PH_3 stays there
