【摘要】 大豆玉米带状复合种植是稳粮增油的重要举措。为探索大豆玉米带状复合种植田杂草的有效防治模式，2022年—2023年全国农技中心重点在黄淮海地区组织开展大豆玉米带状复合种植杂草田间试验和防效考察活动。本研究根据复合种植田杂草发生种类多、危害重等特点，聚焦杂草“治早防小”的关键环节，研究提出“封闭处理+”为主的除草技术模式，并指出目前复合种植除草工作面临着可选有效药剂少、缺乏专用施药机械、残留药害影响后茬生产等问题。针对上述问题提出加快新药登记上市、研发配套农机装备、研究杂草演替规律、做好科学指导等对策建议，为有序推广大豆玉米带状复合种植工作提供了技术依据和模式借鉴。更多还原

【Abstract】 Soybean and maize strip compound planting method is an initiative way to increase the production of grain and oilseed crops. In order to explore the effective weed control mode of soybean and maize strip compound planting,National Agro-Tech Extension and Service Center focused on conducting field trials of weeds in compound planting fields and examining the effectiveness of control in the Huang-Huai-Hai region during 2022-2023. According to the characteristics of compound planting method with many types of weeds and high level of hazard, we focus on the key link of early weed control and small prevention, the "closed treatment +" based weed control technology model was proposed,the problems of fewer effective agents available for weed control, the lack of special application machinery, and the impact of residual damage on the production of later crops were also sorted out. Some countermeasures and suggestions are put forward, such as accelerating the registration of new herbicides, developing agricultural machinery and equipment,researching on the law of weed succession and scientific guidance, which all provides technical basis and model reference for the orderly promotion of composite planting.更多还原
