地面超低容量喷雾雾滴大小和空间分布对比试验

Contrast experiment on the drop size and spatial distribution of ultra-low volume ground spray with three pesticides

通过三种不同类型药液超低容量喷雾雾滴分布对比试验 ,绘制出雾滴空间分布图 ,找出不同药液类型、不同浓度在超低容量喷雾雾滴大小和分布上存在的差异 。

Contrast tests were done with diesel oil,2 5% deltamethrin emulsifiable concentrate(diluted 100 times) and Bt.flowable formulation(diluted 3 times)to find parameters for reference in use of spray technique of tiny droplet in the practice.The result showed that both the drop size and spatial distribution were different among three pesticides.The figures of drop spatial distribution were given.
