摘  要：
选择长沙、宁乡、湘阴三个地区的双季稻田,从2012年至2013年,以冬闲田为对照,冬季种植黑麦草、燕麦、紫云英、白三叶和油菜,研究不同冷季型草对冬闲田杂草群落结构的影响。结果表明,与冬闲相比,种植不同冷季型草后杂草群落均有所减少,其中种植黑麦草小区杂草种类与数量最少,宁乡试验点减少3个种类共552株,长沙试验点减少6个种类共718株,湘阴试验点减少7个种类共452株。种植不同冷季型草对防控稻田冬闲田的杂草均有一定效果,而以种植黑麦草效果最佳。而种植燕麦后杂草群落数量分布较均匀,最有利于保护杂草多样性。

摘  要：
The effects of planting different cool-season grass species including ryegrass,oat,milk vetches,white clover and oilseed rape on the structure of weed community in winter-fallow paddy field were investigated in typical double-cropping paddy fields in Changsha,Ningxiang and Xiangyin from 2012 to 2013. The results showed that weed communities in all the experimental sites were decreased after the planting of different cool-season grass species,as compared with the winter-fallow paddy field. The least weed species and lowest weed number was in the sites of planting ryegrass. The weed communities were decreased by 3 species with 552 plants in Ningxiang,and decreased by 6 species with 718 plants in Changsha site,and decreased by 7 species with 452 plants in Xiangyin. In general,planting different cool-season grasses,especially ryegrass can effectively protect and control the weeds in winter-fallow paddy field. While planting oat can significantly balance the number and distribution of weed communities,which is beneficial to protect weed diversity.
