随着农业生产的发展,近年来改革了棉花种植方法。原来每厢棉田宽2.64米,均分播种四单行,现在则种植三大行,每一大行由两紧靠着的小行组成,故实为三大组六小行,简称“三组六行”。为了解决棉田耕作制度改革后安全喷洒农药问题,我们在公安县荆华大队进行了喷药方法的卫生评价。 With the development of agricultural production, cotton planting methods have been reformed in recent years. The original cotton per box width of 2.64 meters, are sowing four single line, and now planted three lines, each line by the two close to the composition of small firms, it is actually three groups of six small firms, referred to as “three groups of six lines ”. In order to solve the problem of safe pesticide spraying after the cotton farming system reform, we carried out the health evaluation of the spraying method in Jinghua Brigade, Public Security County.
