摘要: 以春玉米大田单独苗前封闭除草方式、单独苗后除草方式为对照,调查苗前封闭除草结合苗后除草施用方式对湖南省永州市玉米田主要杂草空心莲子草[Alternanthera philoxeroides (Mart.) Griseb.]、藜(Chenopodium album L.)和野艾蒿(Artemisia lavandulaefolia DC)的防效及对玉米的安全性。结果表明,苗前喷施精异丙甲草胺1 200~1 800 g/hm2封闭除草,结合苗后喷施28%烟嘧磺隆·莠去津·硝磺草酮复配剂2 100~3 000 g/hm2 除草的方式,对3种杂草在苗后除草剂施药后55 d的株防效和鲜重防效均在90%以上,总体高于单独处理且具长效性和安全性。

Abstract: Using the closed weeding method before single seedling and the single weeding method after seedling in spring maize fields as control, the effects of the closed weeding method before seedling combined with the application method after seedling on Alternanthera Philoxeroides (Mart. Griseb.), Chenopodium album L. and Artemisia lavandulaefolia DC in the maize fields of Yongzhou city, Hunan province were investigated. The results showed that the pre-emergence spraying S-metolachlor 1 200~1 800 g/hm2, combined with post-emergence spraying 28% of nicosulfuron·mesotrione·atrazine 2 100~3 000 g/hm2 , the three kinds of weeds in seedling after applying pesticide, herbicide, the control effect and fresh weight of 55 d were over 90%, the overall higher than that of individual treatment and long-term effectiveness and safety.

Key words: S-metolachlor, nicosulfuron·mesotrione·atrazine, weeds in corn field, weeding effect, long-term effect, safety
