| 摘 要： | 根据杂草稻的发生情况,选择了4种除草剂进行不同剂量、不同施药方法的防治研究。结果表明,试验所用农药明显抑制水稻发芽、出苗,易造成田间缺苗,对水稻的产量有较大影响;各药剂对杂草稻的防治不够理想,但仍有一定的防治效果,尤其是Ronw(复配剂)和丙草胺对杂草稻具有较好的防控作用。建议大田生产上采取农业综合措施防治,可收到显著效果。

| Abstract: | According to the occurrence of weedy rice situation, methods adopting different doses and different application of 4kinds of weedicide have been chosen to carry out studies. The study results show that the pesticide used in the test obviously inhibits rice germination, seedling emergence and easily cause the field seedling shortage and has a great effect on the rice yield. Each herbicide agent for prevention of weedy rice is not ideal, but there is still a certain control effect. In particular, Ronw（Compound agent） and Pretilachlor have good effect on prevention and control of weedy rice. It is suggested that comprehensive agricultural control measures taken in the field production can produce significant effect. |
