种植不同冷季型草对稻田冬闲田杂草群落的影响
Effect of Planting Different Cool-season Grasses on Weed Community in Fallow Paddy Field
摘要
Abstract
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.关键词
