通过对比试验,农泰等草甘膦类除草剂和克无踪等百草枯类除草剂对杀灭免耕稻田杂草和再生稻苗都有较好的防效,对未萌发的落粒谷苗防除效果不明显;晚稻免耕抛秧用41%农泰的适宜用量为6 000~7 500 g/hm2,伏草灵等大田除草剂在立苗后拌第1次追肥撒施效果较好。 Through comparative experiments, herbicides such as glyphosate and other herbicides such as Nongtao et al. Have good control effects on the weedless and regenerated rice seedlings in non-tillage paddy fields, The effect of seedling control was not obvious. The suitable dosage of 41% Nongtai in no-tillage and sowing rice for late rice was 6 000 ~ 7 500 g / hm2. The field herbicide such as fenbazole was the best .
