摘　　要：有效控制水田杂草的发生是有机水稻栽培关键技术。本田杂草控制技术的研究采用深水管理、施用米糠以及田面覆盖稻草、稻壳等有机物的方法进行水田杂草控制试验。结果表明,深水灌溉能够有效控制水田稗草的发生;施用米糠杂草控制效果可达到药剂控制的85%左右;田面覆盖稻草、稻壳等有机物对水田杂草均有不同程度的控制效果,可降低施用米糠成本。The key technology of organic rice culture is controlling the growth of weeds in ri 6100, ce field effectively. Experiment was carried out for control weeds in rice field by deep-water management, rice bran application, coverage of rice field surface with organic matters such as rice straw and chaff. The results showed that deep-water control can effectively control the development of Japanese millet in rice field. The efficiency of weed-control by rice bran application can reach 85 percent of that by herbicide. The coverage of rice field surface with rice straw and chaff can also control the growth of weeds in rice field to varying degree so that to lower the cost of rice bran application.
