井冈山市茶园主要危害性杂草调查

Investigation on Main Hazardous Weeds in Tea Plantations of Jinggangshan City

为了有效控制井冈山茶园杂草,2018—2019年调查了江西省井冈山主要茶叶产区高山、低丘陵茶园的杂草密度与种类及生活型,分析杂草危害特点。杂草种类调查结果表明:井冈山市茶园有杂草112种,共涉及45科,杂草区系丰富,其中以菊科、禾本科、豆科、旋花科占比高,分别为14.29%、9.82%、5.36%和5.35%;杂草生活型及危害特点结果表明:低丘陵茶园杂草以禾本科等一年生杂草为主;高山茶园以多年生杂草为主,防治难度更大。通过对井冈山茶园杂草多样性分析,为茶园绿色防草技术提供依据。

In order to effectively control weeds in tea plantations of Jinggangshan City,the density,species and life forms of main hazardous weeds of tea plantations in high mountains and low hills of Jinggangshan tea producing areas in Jiangxi Province were investigated from 2018 to 2019,and the characteristics of weed damage were analyzed.The results of weeds species investigation showed that there were 112 species of weeds in tea plantations of Jinggangshan City,involving 45 families,and the weed flora was rich,in which Asteraceae,Gramineae,Leguminosae and Convolvulaceae accounted for 14.29%,9.82%,5.36%and 5.35%respectively;the results of life forms and harm characteristics of weeds showed that annual weeds such as Gramineae were the main weeds in low hilly tea plantations,and perennial weeds were dominant in high mountain tea garden,which is more difficult to control.Through the analysis of weed diversity in tea plantations of Jinggangshan City,this paper provided the basis for ecological control technology of weed in tea plantations.
