一九七九年我场在省民航的协助下,继飞机超低容量喷雾防治粘虫成功之后,又成功的进行了飞机低容量防治麦蜘蛛的科学试验。一般超低容量喷雾所使用的农药是一种特制的剂型,载体不是水而是油(有机溶剂),目前,这些溶剂不仅产量有限,而且价钱昂贵,购买及运输都不方便。这样就给 In 1979, with the help of the provincial civil aviation, my field succeeded in carrying out scientific experiments on low-volume control of wheat spiders following the successful control of armyworms with ultra-low-volume aerosols. Pesticides used in general ultra-low capacity sprays are a special form of formulation. The carriers are not water but oils (organic solvents). At present, these solvents are not only limited in yield but also expensive and inconvenient to purchase and transport. Give it this way
