一种由气流、电和光电系统操作的自动间歇式喷雾器已经被研究成功,并用于行作作物的病虫防治。通过对比试验(防治洋白菜、花花椰雾、胡椒等的病虫害)表明,这种喷雾器节省农药。在防治作物病虫害时,应尽量使用较少的农药以减少环境污染。但许多行作作物,其行间空隙较大,且在其生长期内要多次喷药,很容易浪费农药,造成环境污染。为了减少药物
An automatic batch-type sprayer operated by air flow, electricity and optoelectronic systems has been successfully researched and used for pest control of crop plants. By contrast test (prevention and treatment of diseases and pests of cabbage, flower coconut fog, pepper, etc.) show that this sprayer to save pesticides. In the control of crop pests and diseases, should try to use less pesticide to reduce environmental pollution. However, many rows of crops, which have large gaps between rows and are sprayed many times during their growth period, can easily waste pesticides and cause environmental pollution. In order to reduce the drug
