水稻化感作用研究进展及展望

Progress and application of rice allelopathy

水稻种质资源中存在有化感潜力的品种,部分水稻残株对一些杂草也有不同程度的抑制作用,这种特性广泛地分布于水稻的种质库中,研究和探讨水稻化感现象,揭示化感物质及共同作用机理,有效利用水稻化感作用控制田间杂草,不仅能有效提高水稻产量和品质,而且能避免和减少化学除草剂对环境造成的危害。

There exist flee varieties with allelopathy potential in rice germplasm resourees, some rice stump can inhibit the growth of weed to stone extend and this characteristie is distributed in rice gemplam gene bank widely. To study and discuss flee allelopathy phenomena and reveal alleloehemieal and its mechanism,to effectively apply rice allelopathy to control the weed in field, not only can effectively increase the yield and quality, of rice, but also earl avoid and deerease the harm of chemical herbicide to environment.
