摘　　要：防治稻田杂草过分依赖除草剂,使杂草抗药性增强,对生态环境造成破坏,因而开展了浮萍与稻糠控制稻田杂草效果试验。结果表明,水稻种植早期撒施浮萍、稻糠对稻田单子叶、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,对单子叶、双子叶杂草株防效和总鲜重防效在70%左右。The control of weeds in paddy fields relies heavily on herbicides,which in creases the resistance of weeds and causes damage to the ecological environment.Therefore,the experiment with the effect of duckweeds and rice chaff on weeds control in paddy field were carried out.The results showed that the application of duckweed and rice chaff on the monocotyledonous weeds and dicotyledonous weeds in the paddy field had obvious ecological control in the early stage of rice planting.The stem control effect,fresh and heavy control effect of rice chaff can reach more than 50%,but the control time was short,and the inhibitory effect on late-born dicotyledon weeds was limited. In contrast,duckweed had a longer holding period,and its stem control effect,fresh and heavy effect on monocotyledonous weeds and dicotyledonous weeds was about 70%.
