| 摘 要： | 为明确氯吡嘧磺隆与烟嘧磺隆混用对玉米田杂草防除效果及安全性,采用田间药效试验方法对其进行了研究。研究发现:氯吡嘧磺隆(15、17.5、20、22.5、25 g a.i./hm2)与烟嘧磺隆(45、52.5 g a.i./hm2)混用对香附子、藜、铁苋菜、苘麻、马唐均有较高的防效,总体鲜重防效大于95%,尤其对香附子鲜重防效大于97%。氯吡嘧磺隆和烟嘧磺隆混用对玉米是安全的,通过氯吡嘧磺隆与烟嘧磺隆的混用,玉米产量增产率均高于10%。本研究结果表明,氯吡嘧磺隆与烟嘧磺隆混用可有效防除香附子、藜、铁苋菜、苘麻、马唐等夏玉米田常见杂草,尤其是对香附子具有优异的防除效果,并且对玉米安全。

The Mixture of Halosulfuron-methyl with Nicosulfuron: the Effect and Safety of Weed Control in Maize Fields |
| |
| Abstract: | To determine the weed control effect and safety of the mixture of halosulfuron- methyl with nicosulfuron in maize fields, a field experiment was conducted to evaluate the weed control spectrum of single herbicide, the joint effect type and the selectivity index of the mixture. The results showed that: the mixture of
halosulfuron-methyl (15, 17.5, 20, 22.5, 25 g a.i./hm2) with nicosulfuron (45, 52.5 g a.i./hm2) could effectively control Cyperus rotundus, Chenopodium album, Acalypha australis, Abutilon theophrasti and Digitaria sanguinalis in maize field and the overall fresh weight control effect was over 95%, especially the effect on
Cyperus rotundus (more than 97%). The result of safety experiments showed that: the mixture was safe to maize and could increase yield by 10% compared with the blank control treatment. This study shows that the mixture of halosulfuron-methyl with nicosulfuron can effectively control some common weeds in maize field such as Cyperus rotundus, Chenopodium album, Acalypha australis, Abutilon theophrasti, Digitaria sanguinalis, especially Cyperus rotundus and is safe to maize. |
