山东棉田杂草组成及其群落特征
Species Composition and Community Characteristics of Weed in Cotton Fields in Shandong Province
摘要
Abstract
The inverted W-pattern method was used to survey the weed species in cotton fields in Shandong Province.And the weed species diversity was analyzed.Then the weed species and community characteristics were definite.The results showed that the weed in cotton fields in Shandong Province had 81 species,belonged to 24 families,57 genera.Among these species,gramineous weeds was the most,there were 18 species belonged to 10 genera.Compositae weeds was second with 13 species belonging to 11 genera.The dominant weeds were Eleusine indica,Portulaca oleracea,Digitaria sanguinalis,Eclipta prostrate,Phragmites australis,Chenopodium album,Acalypha australis,Calystegia hederacea and Sonchus arvensis.The regional dominant weeds,common weeds and normal weeds had 7,4 and 61 species,respectively.From the regional distribution,the Margalef richness index,Shannon-Wiener index,Simpson index,Pielou index of cotton fields in Wucheng,Kenli,Xiajin,Guangrao and Hekou County were higher than those in other counties.From the cluster analysis,the cotton weed community change had a close relationship with space distance,geographical environment,planting patterns and other factors.The Euclidean distance between Huimin and Gaotang was the minimum of 6.04.The Euclidean distance between Gaoqing and the other counties was the biggest of 23.41.关键词
