通过研究目前葡萄植保作业特点,认为在病虫害防治过程中存在的问题主要是作业机具落后,施药方式粗放,农药有效利用率低,对人员和环境危害严重。分析了背负式机动喷雾喷粉机在葡萄植保作业中使用的可行性,并在无公害葡萄园中进行了可行性试验研究,结果表明使用背负式机动喷雾喷粉机能够降低农药用量80%以上,使叶子正反两面充分着药,既能提高作业效率,又能提高无公害葡萄的品质。
By studying the current grape plant protection operation characteristics, it is considered that the main problems in pest control are backward work tools, extensive application methods, low effective utilization of pesticides and serious harm to personnel and the environment. The feasibility of knapsack motor spray duster in grape replanting operation was analyzed and the feasibility test was carried out in pollution-free vineyard. The results show that the use of knapsack sprayer can reduce the dosage of pesticide more than 80% , So that the positive and negative leaves full of medicine, both to improve operating efficiency, but also improve the quality of pollution-free grapes.
