草铵膦与乙羧氟草醚复配对一年生杂草的联合作用和非耕地除草效果研究

摘要

[Aims]The study aims to confirm the coeffect of glufosinate with fluoroglycofen and the control effect of glufosinate· fluoroglycofen 20% ME against annual weeds in non-cultivated land.[Methods]The method of stem-leaves spraying was used to determine the coeffect of two herbicides indoor and Field trais were carried out on the best proportion selected.[Results]The results showed that the coeffect of glufosinate and fluoroglycofen complex with 19"1 was better,the recommended dosage for glufosinate· fluoroglycofen 20% ME was 600~900g a.i. /hm2,and the overall control effect on annual weeds non-cultivated land reaches 95. 7% ~ 97. 6% after 30 days.[Conclusions]The complex of glufosinate and fluoroglycofen was highly complementary and synergy was obvious to annual weeds. and glufosinateofluoroglycofen 20% ME can control annual weeds in non-cultivated land effectively.%[目的]为明确草铵膦、乙羧氟草醚联合作用效果和20%草铵膦·乙羧氟草醚ME对非耕地一年生杂草的防除效果.[方法]采用茎叶喷雾法测定了2种除草剂室内联合作用试验,并对筛选出的最佳配比加工成20%草铵膦·乙羧氟草醚ME进行了田间药效试验.[结果]草铵膦、乙羧氟草醚以19"1复配对非耕地一年生杂草的联合作用较好,20%草铵膦·乙羧氟草醚ME的推荐使用剂量为600~900g a.i. /hm2,药后30 d对非耕地一年生杂草的总体防效可达到95.7% ~97.6%.[结论]草铵膦、乙羧氟草醚复配互补性强,对反枝苋、马齿苋、狗尾草、马唐等一年生杂草增效作用明显,20%草铵膦·乙羧氟草醚ME能够有效防除非耕地一年生杂草.
