一、简略的发展史 据各方面的报道,茶园使用除草剂(或称除莠剂),还是在近半个世纪前开始的。东北印度于五十年代在托克莱试验站进行了除草剂研究。在他们的早期试验中认为西玛津、阿特拉津对防治阔叶草是可行的。但托克莱在1961年才推广化学除草。1965～1967年他们进一步推荐了西玛津、阿特拉津、茅草枯以及百草枯等防治茶园杂草。六十年代该站采用百草枯作为茶园防治杂草的基本除莠剂;2,4—D、 First, a brief history of development According to various reports, the use of herbicides (or herbicides) in the tea plantations began almost half a century ago. Northeast India conducted a herbicide study at the Tokelai Station in the 1950s. In their early trials, Simazine and atrazine were considered feasible for the control of broad-leaved grasses. But Tokelal in 1961 to promote chemical weeding. From 1965 to 1967, they further recommended the control of tea plantation weeds such as simazine, atrazine, thatch and paraquat. In the 1960s, paraquat was used as the basic herbicide for controlling weeds in tea gardens. 2,4-D,
