| 摘 要： | 稻田杂草过分依赖除草剂,使杂草抗药性增强,同时对生态环境造成破坏。笔者通过田间试验表明,水稻种植早期撒施浮萍、稻糠对稻田单、双子叶杂草有较明显的生态控制作用,稻糠对杂草的株防效和总鲜重防效可达50%以上,但控制时间较短,对晚发双子叶杂草的抑制作用有限。相较之下,浮萍持效期更长,对单、双子叶株防效和总鲜重防效在70%左右。

| Abstract: | The Effect of Duckweeds and Rice Chaff on Weeds Control in Paddy Field
ABSTRACT: With over dependence of herbicides in paddy field, the weeds resistance and serious environmental problems were increased. The results of field experiments showed that the application of duckweeds and rice chaff at early stage of rice planting could obviously control monocotyledons and dicotyledonous weeds in paddy field. The control effect of rice chaff on weeds more than 50% in number and total fresh weight, but the control time was short, and the control effect was limited on late-growing dicotyledonous weeds. In contrast, duckweeds had a longer duration period and better control effect on monocotyledons and dicotyledons in number and total fresh weight, which were both more than 70%.
