摘要
对加拿大一枝黄花(Solidago canadensis)在复耕麦田的发生与防除技术进行研究。结果表明,复耕麦田加拿大一枝黄花2月中旬开始出苗,3月初进入出草盛期,至4月下旬出草基本停止。加拿大一枝黄花对小麦产量有较大影响。抛荒地经翻耕复种小麦后可减少加拿大一枝黄花出苗51.3%,麦子生育期拔草1次可降低加拿大一枝黄花地下根茎鲜重75.6%。20%使它隆EC 750 mL/hm2与10%甲磺隆WP 75 g/hm2混配,于加拿大一枝黄花木质化前苗期处理,对地上部分株数和鲜重防效可达93.8%和97.6%。
The occurrence and control of Solidago canadensis in resumed wheat field were studied during 2004-2005. The result indicated that the emergence of Solidago canadensis started in the middle ten days of February, went into a peak period in early March and stopped in the last ten days of April. It had a great influence on wheat yield. Resuming tillage in waste land and planting wheat could reduce the emergence of Solidago canadensis by 51.3%, and weeding by hand for one time at the growth stage of wheat could reduce the fresh weight of Solidago canadensis roots by 75.6 %. Applying the mixture of 20 % fluroxypyr EC 750 mL/hm^2 and 10 % Methsulfuron-methyl WP 75 g/hm^2 to the plantlets of Solidago canadensis before lignification could effectively control Solidago canadensis, and the control efficiency was 93.8 % or 97.6 % in terms of plant number or above-ground fresh weight.
