江苏靖江县柏木乡东南村农民陈树勋研制成功了一种用于农用喷雾器上的超高速旋水垫片。这种超高速旋水垫片,具有结构简单、制造方便、成本低(每个5分钱)、使用寿命长(每个能连续喷雾2000个小时左右)等特点。经上海植保总站、江苏省农科院和省植保站的有关专家鉴定认为,使用该旋水垫片喷雾,雾滴细,物理性能好;喷角大,漂移性好。花上5分钱买个垫片,安装在农用喷雾器上,可节约农药50%,省工时30%以上,一个种3亩地的农户在喷雾器上安装这种垫片。一年可节省农药费10元。同时, Chen Shu-hsun, a farmer from southeast village of Bai Mu Township, Jingjiang County, Jiangsu Province, developed a super high-speed hydrosphere gasket for agricultural sprayer. This super-high speed water shim, with simple structure, easy manufacture, low cost (each 5 cents), long service life (each can spray 2000 hours or so) and so on. By the Shanghai Plant Protection Terminus, Jiangsu Provincial Academy of Agricultural Sciences and Provincial Plant Protection Station experts believe that the use of the rotary shim spray, fine droplets fine, good physical properties; spray angle, good drift. Spend 5 cents to buy a gasket, installed in the agricultural sprayer, can save 50% of pesticides, provincial working hours more than 30%, a kind of 3 acres of land in the sprayer to install this gasket. One year to save pesticide costs 10 yuan. Simultaneously,
