旱田播后芽前使用的除草剂品种较少,进口除草剂又受到一定限制。为了解决这一问题,我场于1987年对国产60％丁草胺乳油进行了旱田播后芽前选择性试验,现将试验情况小结如下: (一)试验方法:以“苏豆1号”大豆、“抗4”高粱、“150”玉米、“村农”元麦、“早熟3号”大麦、“扬麦4号”小麦、“苏蜜1号”西瓜、“泗棉2号”棉花、“沪油9号”油菜等9个为供试作物,每一作物每一重 There are fewer varieties of herbicides used in the field before and after sowing, and some restrictions are imposed on imported herbicides. In order to solve this problem, my field in 1987, 60% of butachlor EC made on the field after sowing and bud pre-selective test, the test is summarized as follows: (A) Test Method: “Su Dou 1” Soybeans, “Anti-4” sorghum, “150” maize, “Village Farmers” Yuan Mai, “Early Maturing” barley, “Yangmai 4” wheat, “Sumei No.1” watermelon, “Simian No.2” cotton , “Huyou 9” rape and other nine for the test crop, each crop weight
