Keyword:  除草剂高粱不同时期除草效果;
Abstract: [目的]探讨3种除草剂在高粱不同生长时期施用的除草效果及对高粱生长和产量的影响.[方法]使用农达、38%琇去津、史它隆3种除草剂对泸糯8号和泸州红1号2个高粱品种在移栽前7d、移栽前、移栽成活后和中耕期进行除草处理,观察3种除草剂在不同施用时期的除草效果及对高粱生长和产量的影响.[结果]除在移栽成活后、中耕期施用农达有强药害外,其余各处理基本无药害,除草效果以农达最好,史它隆仅对宽叶杂草效果较好,38%琇去津药效较慢.相对于清水对照,在移栽前7d施用农达、移栽成活后施用38%琇去津对杂交和常规高粱的产量及其生长性状的增加效应最明显.[结论]为高粱地杂草的防治提供了理论依据.
