In order to use chemicals in paddy fields in addition to barnyardgrass, to save labor, save time, reduce labor intensity, improve economic efficiency, from the plant protection station of Jiangxi Provincial Department of Agriculture and Animal Husbandry, Yichun Agricultural Bureau of Plant Protection Branch, Fuzhou Agricultural Research Institute, Taihe County Bureau of Agriculture plant protection station presided over in 1983 in Wanli County Leisure Town Lianxing Brigade, Taihe County Plant Protection Station, Fuzhou Regional Agricultural Science and other three barnyard grass more rice areas, respectively, in the early and late rice seedling and Daejeon “Wo strong” except barnyard test demonstration. A total of 92.9 acres of pilot demonstration area, of which seedling demonstration area of 22.6 acres, Honda pilot demonstration area of 70.4 acres. Now the experimental results of each point are summarized as follows:
