摘要: 随着栽培方式的日益简化,草害成了水稻减产的重要因素,笔者以常规除草剂除草方式为对照,研究了转基因抗草铵膦杂交早稻香125S/Bar68-1在直播、抛秧和机插3种栽培方式中草铵膦的应用效果。研究结果表明:在3种栽培方式中,草铵膦除草效果都优于常规除草,尤其在杂草较多的直播田优势更加明显;虽然个别产量相关性状在不同年份存在显著差异,但草铵膦除草剂除草对转基因早稻的实际产量没有显著影响。

Abstract: With the simplification of rice cultivation, weeds have become an important factor which could cause yield loss. In this paper, the application effects of non-selective herbicide glufosinate on early season rice hybrid Xiang125S/Bar68-1 under three cultivation patterns (direct seeding, throwing seedling and mechanical transplanting) were studied, and convention herbicide was used as control. The results showed that the weeding effect of glufosinate treatment was superior to that of convention herbicide treatment among the three kinds of cultivation patterns, and the superiority was more apparent, especially in direct seeding field with more weeds; although a few yield-related traits were significantly different among different years, the yield of transgenic early season rice under glufosinate herbicide treatment had no significant difference to that under convention herbicide treatment.
