摘要： 为解决山西省高粱田杂草防除难的问题，采用完全随机区组的试验方法进行了山西省高粱田土壤封闭剂和茎叶处理剂的筛选研究。结果表明：播后苗前土壤处理，莠去津、金都尔和2,4-D丁酯单剂用量分别在6750、1350、1200 mL/hm2以下时，高粱出苗安全且除草效果好；莠去津和金都尔复配组合最优配比为5250 mL/hm2+ 900 mL/hm2。苗后茎叶处理，除草单剂二氯喹啉酸、莠去津、二甲四氯、2,4-D丁酯除草效果较好且对高粱产量影响较小，使用剂量分别为750 g/hm2、2700 g/hm2、1500 g/hm2、 1050 mL/hm2；复配剂最优配比为莠去津2250 g/hm2+二氯喹啉酸 600 g/hm2、莠去津2250 g/hm2 +2,4-D丁酯300 mL/hm2和苯达松3000 mL/hm2+二氯喹啉酸750 g/hm2。

Abstract: To solve the problem of difficult weed control in Shanxi sorghum field, soil blocking agents and foliage treatment agents were screened for the application by using a randomized complete block test. The results showed that for the pre-emergence treatment, when the concentration of Atrazine, Metolachlor and 2,4-D Butyl ester was lower than 6750, 1350 and 1200 mL/hm2, respectively, there were less impact on sorghum emergence and good effect of weeding. The optimal ratio of Atrazine and Metolachlor complex combination was 5250 mL/hm2 900 mL/hm2. For the post-emergence treatment, there were good effect of weeding and less impact on sorghum yield when the concentration of Quinclorac, Atrazine, MCPA and 2,4-D Butyl ester was 750 g/hm2, 2700 g/hm2, 1500 g/hm2 and 1050 mL/hm2, respectively. The optimal ratio of Atrazine Quinclorac, Atrazine 2,4-D Butyl ester, Bentazon Quinclorac complex combination was 2250 g/hm2 600 g/hm2, 2250 g/hm2 300 mL/hm2 and 3000 mL/hm2 750 g/hm2, respectively.
