贵州茶园杂草种类有66科300多种,一年四季均有发生。生产茶园,春季杂草便萌发滋生夏季马唐、狗尾草、蟋蟀草等遍地皆是;幼龄茶园中茅草、蕨类与茶竞长,管理稍有疏忽,则草比茶茂。多种杂草的发生,既大量剥夺了茶树的养分,又给茶树病虫的滋生、繁殖提供了场所,对茶树生长影响甚大。为了保护茶树的正常生育,从幼龄茶园至茶树封行郁蔽之前,每年必须进行几次除草,而幼龄茶园的要求更为迫切,在夏季由于工作繁多,为了除草更加剧了劳力的紧张程度。茶园中对一般杂草的防除,每亩每年须花人工8～12个,仅工资即达12～18元。因此试验研究茶园中经济、有效、快速的除草方法,便成为茶叶生产现代化中一个急待解决的问题。 There are over 66 species of weeds in Guizhou tea gardens, all of which occur throughout the year. The production of tea plantations, the spring weeds will germinate in summer Cotatum, Setaria, cricket grass everywhere; young tea garden thatch, ferns and tea competition long, the management of a slight negligence, the grass than tea. A variety of weeds occurred, both a large number of deprived of tea tree nutrients, but also to tea plant diseases and insect pests breed, provide a place for breeding, a significant impact on the growth of tea. In order to protect the normal growth of tea trees, it is necessary to carry out weeding several times a year from the young tea plantations to the closure of tea trees. The demand for young tea plantations is even more pressing. In the summer, due to a great deal of work, labor stress is exacerbated by weeding degree. Control of weeds in the tea plantation, per acre to be artificial each year 8 to 12, that is, wages alone amounted to 12 to 18 yuan. Therefore, the experimental study of economic, effective and rapid weeding methods in tea plantations has become an urgent issue in the tea production modernization.
