摘　　要：为探究豫南地区麦后直播稻田间杂草化除的有效技术方法,通过对豫南地区麦后直播稻田的杂草种类、数量进行调查分析,开展了不同除草剂对杂草的防除效果和对直播稻生长的影响试验。结果表明:豫南地区麦后直播稻田杂草草相复杂,优势杂草种类多;麦后直播稻田杂草的有效防除可显著提高直播稻产量。重点做好直播稻田芽前土壤封闭处理,芽后田间杂草防除要根据田间草相有针对性地选择除草剂。In order to explore the effective weed chemical control technology in direct seeding rice field after wheat in southern Henan Province,this study investigated and analyzed the species and quantity of weeds in direct seeding rice field after wheat in southern Henan Province,and studied the control effect of different herbicides on weeds and the influence on the growth of direct seeding rice through field experiments.The results showed that the weeds were complex,and there were many dominant weeds in direct seeding rice field after wheat in southern Henan Province.Efficient control of weeds in direct seeding rice field after wheat could significantly increase the yield of direct seeding rice.Emphasis should be placed on the soil sealing treatment before the sprout in direct seeding rice field,and herbicides should be selected according to the grass in the field for weed chemical control after the sprout.
