随县是一季中籼稻地区,大部社队田多劳少,往往因缺少劳力而使下少田塊草荒严重,特别是鸭舌草、荆三稜、稗草和牛毛毡等杂草,不仅数量多,而且不易薅死,与秧苗争水、争肥、争光,严重者使稻谷减产一两成。为了寻求适合在本地区耕作栽培制度条件下使用的除草剂,并为今后大面积推广使用创造经验,1964年我们在环城公社八一大队作了五氯酚钠的除莠试验,现将试验情况和结果简报于后。 Suixian is a seasonal mid-season indica rice area, most of the community team work more and more less, often due to lack of labor and make Xiaodan lord grassland serious, especially the weeds, Jing Triangulation, barnyard grass and cattle blankets and other weeds, not only the number More, but not easy to die, fight water with the seedlings, fight fat, win glory, serious, one or two cut rice production.
