摘要
2008年,在冀西北坝上地区莜麦田进行除草剂筛选试验。结果表明:72%2,4-D丁酯乳油、巨星(75%苯磺隆干悬浮剂)、20%二甲四氯可溶性粉剂都可有效杀灭莜麦田间阔叶杂草。几种除草剂的建议使用浓度为:72%2,4-D丁酯乳油为750mL/hm2,巨星(75%苯磺隆干悬浮剂)为18g/hm2,20%二甲四氯可溶性粉剂为1950g/hm2。野燕枯水剂和72%2,4-D丁酯乳油、20%二甲四氯可溶性粉剂配合使用,可以有效防除莜麦田间的阔叶杂草和野燕麦。建议使用浓度为:72%2,4-D丁酯乳油+48%野燕枯水剂为750g/hm2+3375mL/hm2;20%二甲四氯粉剂+48%野燕枯水剂为1950g/hm2+3375mL/hm2。
The abstract in 2008,the area conducts the weeding research on the Hebei northwest dam to the naked oat field weed.The result indicated：72% 2,4-D the Ding ester cream,the giant star（75% benzene sulphur do deflocculant,22% armor tetrachloride soluble medicinal powder to be possible prosperously）to eliminate the naked oat field broad-leaf weed effectively,several weed killer＇s suggestion use densities are：72% 2,4-D the Ding ester cream is 750mL/ha;The giant star（75% benzene sulphur do deflocculant is 18g/ha prosperously）;22% armor tetrachloride soluble medicinal powder is 1950g/ha.Wild Yan Ku and 72% 2,4-D the Ding ester cream,22% armor te-trachloride soluble medicinal powder coordination use,may guard against the naked oat field effectively the broad-leaf weed and the wild oat.The suggestion use density is：72% 2.4-D Ding ester cream＋48% wild Yan Ku 750g/ha＋3375mL/ha;22% armor tetrachloride medicinal powder＋48% wild Yan Ku 1950g/ha＋3375 mL/ha.
