小麦田常用除草剂啶磺草胺水分散粒剂(WG)作用靶标为乙酰乳酸合成酶(ALS)。石河子大学农学院通过研究新疆不同品种小麦的ALS对啶磺草胺WG的耐受性,确定啶磺草胺WG对不同品种小麦的安全浓度,筛选耐药性较好的小麦品种。科研人员利用室外盆栽法,将用清水浸泡24小时的小麦种子播种在花盆里,待幼苗长至3~4叶期后,喷施不同浓度的啶磺草胺WG,施药5天后提取 Commonly used herbicide in the field of wheatgrass sulfasalazine water dispersible granules (WG) target of acetolactate synthase (ALS). College of Agronomy, Shihezi University The safety of SLS WG to different wheat cultivars was determined by studying the tolerance of ALS to SLS WG in different wheat cultivars in Xinjiang, and the wheat varieties with better drug resistance were screened. Researchers use outdoor potting method, will be soaked in water for 24 hours of wheat seeds sown in the pot until the seedlings grow to 3 to 4 leaf stage, spraying different concentrations of sulfasalazine WG, 5 days after the application of the extraction
