手动喷雾器是目前农村主要施药工具。据北京农业大学试验,把手动喷雾器大孔径(直径1.3mm)喷头片换成小孔径(直径0.7mm)喷头片,将大容量(HV)喷雾法(每亩喷液量大于40升,亦称常规喷雾法),改成低容量喷雾法(每亩喷液量1—10升),工效可提高倍十左右,且用药少,防效好。1982年我们应用低容量施药技术,对水稻害虫纵卷叶螟、稻飞虱、浮尘子进行了防效试验,现将情况报告如下:
Manual sprayer is currently the main pesticide application tool in rural areas. According to the experiment of Beijing Agricultural University, the large sprayer with a large aperture (diameter 1.3mm) is replaced with a small aperture (diameter 0.7mm) Conventional spray method), into a low-volume spray method (spray volume per acre 1-10 liters), work efficiency can be improved about 10 times, and less medication, good control effect. In 1982, we applied low-capacity pesticide application technology to control pest-borne leafrollers, planthoppers and floating dusts. The report is as follows:
