近年来,各地大力推广低容量施药防治农作物害虫,取得了可喜的效果。但是,应用低容量施药防治水稻病害,是否也有效果?因此,我们在1984年晚稻期间用低容量喷雾防治水稻纹枯病,结果表明,应用小孔径片低容量施药技术,同样可以防治水稻病害。 一、材料与设计 1.试验材料 用工农—16型背负式手动喷雾器,喷头片孔口直径有1.3毫米和0.7毫米两种规格;5％井岗霉素水剂在晚稻品种754田内喷施。
In recent years, various localities have vigorously promoted the application of low-volume pesticides to control crop pests and achieved encouraging results. However, is it effective to use low-volume pesticides to control rice diseases? Therefore, we used low-volume spray to control rice sheath blight during the late rice season in 1984. The results showed that the application of low-capacity small-aperture tablet technology could also control rice Diseases. First, the material and design 1. Experimental materials with a worker-peasant -16-type hand-held sprayer, nozzle orifice diameter of 1.3 mm and 0.7 mm two specifications; 5% Jing Kongmycin agent sprayed in the late rice varieties 754 fields.
