以转基因抗除草剂杂交早稻“株1S/Bar68-1”为材料，常规除草剂2次除草方式为对照，探讨了草铵膦1次除草方式在水稻直播栽培中的应用效果。结果表明：与常规除草（效果表现为千金子草害）相比，灭生性除草剂草铵膦除草对供试材料株叶形态无显著影响，但使田间杂草数量减少85.3％，减少产量损失33.1％，节约成本37.5％。“株1S/Bar68-1”直播栽培中应用草铵膦除草剂1次除草的技术要点为：草铵膦有效成分0.6 g/L，每公顷用量720～960 L（有效成分剂量432～576 g/hm2），于分蘖末期紧挨冠层均匀喷雾，冒头杂草重点喷施。

The weed control effect of glufosinate in direct seeding field of transgenic herbicide resistant early hybrid rice Zhu 1S/Bar68-1 was studied with conventional herbicide as control.The results indicated that the plant type of hybrid rice was not obviously affected , but the stems of weed were decreased by 85.3%, the grain yield loss was decreased by 33.1%and the weeding cost was decreased by 37.5%in treatment of spraying glufosinate once compared to control.The key techniques of weed control by glufosinate on direct seeding rice included that the dosage of glufosinate was 432~576 g ( a.i.)/hm2 and the glufosinate should be sprayed close to rice canopy at the end of tillering stage.
