闽中地区再生稻田杂草种类及其群落特征
Composition and Characteristics of Weed Community in Regeneration Rice Fields in Central Fujian
摘要
Abstract
Surveys were conducted on the weeds grown in the regeneration rice fields at 1 1 affiliated villages in 5 townships of Youxi Country in central Fujian by the sampling method of inverted W.A total of 1 7 species belonging to 1 1 families were found.Among them,3 were of the Gramineae and Cyperaceae families,and two of the Lythraceae and Onagraceae families.Based on their dominance and diversity in 6 villages,such as Maoze,8 species were considered the dominant weeds, which included Echinochloa crusgalli , Euphorbia lathyris , Eclipta prostrata , Lindernia procumbens , Rotala indica , Ammannia rotundifolia , Monochoria vaginalis , and Heleocharis plantagineiformis . The weed community mainly consisted of M. vaginalis , E . lathyris , E . crusgalli,E .prostrata,R.indica and L.procumbens .The species richness,diversity and evenness of the communities in the fields at Peng,Geqiutou and Maze villages were higher than those of the others.Significant differences on the composition of the weed communities were observed among the surveyed villages.The variations might be attributed to the differences on the local ecology,as well as the history of rice cultivation and applied herbicides in those fields at Youxi.关键词
