苎麻、亚麻地杂草化学控害技术研究

Research on Chemical Control of the Weeds in Ramine and Flax Farmland

种植苎麻、亚麻是我区实施农业产业化结构调整的重大举措 ,近三年来发展迅猛。但是 ,杂草危害是目前困扰其生产发展的严重技术问题。 2 0 0 1年以来我们对苎麻、亚麻地进行了杂草种类及危害的调查 ,同时对采用化学方法控制杂草危害进行了专项研究 ,选择目前主要推广的 5种化学除草剂 ,掌握在苗期施用控制其危害 ,苎麻苗床除草效果达 88.47～ 91 .97% ,亚麻苗期达 82 .81～ 83.1 5 % ,控害效果良好。特别是 5 %金草克EC和 5 %精克草能EC在使用成本和效果上都值得在生产上推广应用。

Ramine and flax are important economic crop in Fuling distract.In last three year,the danmage by weed has been very serious since 2001.The species of weeds and their damage were investigated. At the same time ,chemical control method was also studied to weed breeding. In ramine farmland,the control is between 88.47%～91.97%, In flax farmland,it is between 82.81%～83.15%, Efficiency of 5% Jinchaoke EC and 5% Jinkechaoneng EC were special good, and the cost of control is lower too.
