标准施药机械玉米封闭除草减量试验

Experiment on Closed Weeding of Maize by Standard Application Machinery

为发展生态质量效益型农业,提高农产品质量和市场竞争力,通过应用标准施药机械、标准喷头和喷头体,选用当地实际生产常用的除草方法和除草剂种类,进行玉米田土壤封闭除草减量试验。结果表明:应用标准施药机械和农民自制牵引式喷杆喷雾机更换标准喷头、喷头体,可实现除草剂减量10%～20%。

In order to develop ecologically efficient agriculture and improve the quality and market competitive-ness of agricultural products, tests for the reduction of soil herbicides in maize fields will be conducted by ap-plying standard application machinery, standard sprinklers and sprinklers, and selecting commonly used wee-ding methods and herbicide types used in local actual production. The results shoned that the standard sparying machine and the homemade drag rod sprayer made by famers could reduce the dosage of herbicide by 10%-20% by changing the standard nozzle and sprinkler body.
