摘要
Abstract
A location investigation on the occurrence and hazard of autumn weeds in Yixing hilly tea gardens in Jiangsu province was carried out by using M -shape 9-point sampling method .There were 82 main weed species in 72 genera of 40 families .Among them ,there were 66 species of broadleaf weeds ,occupying 80 4.9% of the total weed species ;there were 9 species of gramineous weeds ,accounting for 10 9.8% .As for the life form of these weed species ,annual weed species ac‐counted for 50% ,biennial weed species accounted for 13 4.1% ,and perennial weed species occupied 36 5.9% .Through data analysis ,we found that the dominant weeds with the relative abundance of over 10% in autumn included Digitaria sangui‐nalis ,Geranium carolinianum ,Oxalis corniculata ,Rubus hirsutus ,Vicia sativa and Conyza canadensis .The composite and gramineous weeds were the dominant weed populations in autumn in Yixing hilly tea gardens .关键词
