摘要: 为筛选适宜在大豆(Glycine max)-玉米(Zea mays)带状复合种植田使用的土壤处理除草剂,本试验选用10种药剂,进行田间小区试验,测定除草剂对杂草的防治效果及对大豆和玉米的安全性。结果表明:在推荐剂量下,精异丙甲草胺、异丙甲草胺、乙草胺、唑嘧磺草胺、扑草净、噻吩磺隆、2,4-滴异辛酯对大豆、玉米安全;二甲戊灵对大豆有轻微药害,嗪草酮、西草净对大豆和玉米均有轻微药害,药后25 d恢复正常。推荐剂量下,精异丙甲草胺、异丙甲草胺、二甲戊灵、乙草胺对狗尾草和马唐防效在90%以上;唑嘧磺草胺和扑草净对反枝苋和藜防效在90%以上,其他药剂防效较低。在大豆-玉米带状复合种植田可优先选用精异丙甲草胺、异丙甲草胺、乙草胺防治禾本科杂草,选用唑嘧磺草胺或扑草净防治阔叶杂草。

Abstract: In order to screen out the pre-emergence herbicides suitable for soybean-maize strip intercropping field,10 herbicides were tested in the study,and the effect on weed control and the safety of Glycine max and Zea mays were determined. The results showed that S-metolachlor,metolachlor,acetochlor,flumetsulam,prometryn,thifensulfuron-methyl and 2,4-D isooctyl ester were safe for soybean and maize at the recommended dosage,but pendimethalin caused a slight phytotoxicity to soybean. Both metribuzin and butachlor caused a slight phytotoxicity to both soybean and corn,which recovered after 25 days since those herbicides application. The control efficacies of S-metolachlor,metolachlor,pendimethalin and acetochlor on Setaria viridis and Digitaria sanguinalis were over 90%. The control efficacies of flumetsulam and prometryn on Amaranthus retroflexus and Chenopodium album reached above 90%,while the others had a lower control efficacies. The results above indicated that in soybean-maize strip intercropping field,S-metolachlor,metolachlor,and acetochlor should be applied when there were a large number of gramineous weeds;and flumetsulam or prometryn is the first choice to control broadleaf weeds.
