机动药械防治棉铃虫效果比较

Comparative Research on Chemical Spraying Technique for the Control of Cotton Boll

根据试验和生产实践调查 ,机动药械防治棉铃虫 ,效果显著优于手动药械 ,防治工效比手动药械高 1.3 7～ 2 .74倍 ,防治成本比手动药械低 6.4%～ 2 0 .0 %,劳动强度大幅度降低。在机动药械中 ,以泰山WFB 18BC型喷雾喷粉机综合效益最好 。

The chemical efficiency of spraying pesticides by machine was 1.37～2.74 times more than by hand in controlling cotton boll and the labor intensity was largely reduced. The sprayer (Qinshang WFB-18BC) was with the best spraying efficiency in application and was widely used.
