摘要
为江西省新建茶园杂草的绿色防控提供参考,对江西省井冈山新城镇黄夏村新植茶园基地中杂草的发生规律及危害情况进行调查与分析,并采用覆盖除草、绿肥控草和机械清草3种处理进行防除,比较不同防除技术对新植茶园杂草的防除效果。结果表明:该基地中有杂草23科46种,菊科和禾本科杂草分别占总杂草的26.09%和19.57%;危害夏季茶树生长的杂草有45种,占总杂草的97.83%,危害茶树生长春、夏、秋季的杂草有13种,占调查茶园杂草总数的28.26%。不同除草方式均能有效抑制杂草的生长,除草效果依次为覆盖除草>绿肥控草>机械清草>不除草。建议茶园杂草绿色防控采用覆盖除草、绿肥控草与机械清草相结合进行防除。
In order to provide references for green controlling of weeds in young tea plantation,in this paper the authors investigated and analyzed the occurrence and damage of weeds in the young tea plantations in Huangxia Village,Jinggangshan New Town,Jiangxi Province,and adopted three treatments to control weeds,including cloth covering,green manure planting,and machinery weeding,and the control effects of different control techniques on weeds in young tea plantation were compared.Results:There were 46 species of weeds belonging to 23 families in the base,and Asteraceae and Gramineae weeds accounted for 26.09%and 19.57%of the total weeds,respectively;There were 45 species of weeds that harmed the growth of summer tea trees,accounting for 97.83%,there were 13 kinds of weeds that harmed the growth of tea trees in spring,summer and autumn,accounting for 28.26%of the total number of weeds in the tea plantations surveyed.Different weeding methods could effectively inhibit the growth of weeds.The weeding effects ranked as mulch weeding>green manure control>machinery weeding>control.It was suggested that the green control of weeds in young tea plantations should be combined with cloth covering,green manure planting,and machinery weeding.
