摘要
为明确50%异甲·特丁净乳油在花生田的应用前景,采用田间小区试验、取样考种的方法,观察了其对花生田主要杂草的控制作用和对花生产量的影响。结果表明,50%异甲·特丁净乳油对花生田马唐、牛筋草、反枝苋、马齿苋等多种一年生杂草均有好的防除效果,随用药量的增加防效逐渐提高,药后40d株防效在85%以上,鲜重防效在90%以上,好于异丙甲草胺、特丁净两药剂单用常规剂量处理的防效,显著提高了花生的产量。
The weed control effects of metolachlor+terbutryn 50% EC,subsequent dynamics in peanut fields and the effect of metolachlor+terbutryn 50% EC on crop yield were studied to evaluate the application prospect of metolachlor+terbutryn 50% EC.The result showed that there was a good control of metolachlor+terbutryn 50% EC to digitaria sanguinalis,eleusine indica,amaranthus retroflexus,portulaca oleracea and many other annual weeds.The effect was gradually higher along with increasing of the dosage. 40 Days after treatment, the plant and the fresh weight control effect were 85% and 90% respectively.It was better than the routine dose treatment of metolachlor and terbutryn. The peanut yields were improved obviously.
