农户应用磷化铝熏蒸贮粮害虫,过去采用布包药片留线投药法,实践证明有诸多缺点,不仅施药深度不易掌握,且施药操作时间长。为了提高安全性,我们创制简易施药工具-竹筒施药器。 取直径2—2.5cm竹杆一根,根据容器内粮堆高低和施药量截取适当长度,分节用刀刮去竹杆节间对应两侧,留下的侧孔(大小以装进药片为宜),然后将竹杆下端削成楔形,使用时,根据用药量,分节装药后插入粮堆,熏蒸结束拔出施药器取出药片残留物可再次使用。
Farmers use aluminum phosphide fumigation of stored grain pests, past the use of cloth bags tablets line administration method, the practice has proved that there are many shortcomings, not only the depth of application is not easy to grasp, and the application of long operating time. In order to improve safety, we create a simple application tool - bamboo tube applicator. Take a diameter of 2-2.5cm bamboo pole, according to the level of the container inside the container and the amount of pesticide interception appropriate length, the section with a knife scrape off the bamboo on both sides of the corresponding on both sides of the left side hole (size to fill the tablet Suitable), and then the lower end of the bamboo cut into wedges, when used, according to the amount of medication, the section after the charge into the food pile, fumigation pull out the applicator to remove the tablet residue can be re-used.
