杂草是农业生产的大敌,它们与茶树争夺阳光、水分与养料,严重地影响茶树生长。而大多数杂草具有较强的生命力,生长非常迅速,尤其是温暖湿润的南方茶区杂草更易生长,严重的甚至引起茶树衰亡。如广西柳江县新兴农场由于禾本科杂草铺地(?)(Panicum repens Lism)的繁殖致使200多亩茶园衰败,产量大幅度下降,为害十分严重。因此茶园杂草防治是一项十分重要的管理工作,不能忽视。过去茶园除草大多用人 Weeds are the enemy of agricultural production, they compete with the tea tree sunshine, moisture and nutrients, seriously affecting the growth of tea trees.
