摘　　要：通过总结2022年江苏省水稻田杂草发生概况,阐明了当年水稻田杂草发生具有发生面积大、为害程度重、杂草密度高、为害持续时间长、区域间发生程度差异大、直播稻田发生重于机播田栽等特点;分析当年杂草重发的主要原因是杂草基数高、水稻种植和管理方式利于杂草发生、持续高温干旱影响除草效果、药剂选择及使用时机把握不准,并提出了强化监测预警、坚持科学防控、强化技术服务指导、强化技术储备的防控策略,为科学、合理、安全防控水稻田杂草提供依据。This paper presents a summary of the general situation of weeds occurrence in Jiangsu province in 2022.It was revealed that the prevalence of weeds in rice fields in 2022 exhibited the following characteristics:high occurrence,significant damage,high weed density,prolonged damage duration,notable regional variation in occurrence,and a greater prevalence in direct seeding rice fields compared to machine-seeding rice fields.Besides,the primary causes of serious weed occurrence in the current year were analyzed,including the high weed seed base,methods of rice cultivation and management practices,continuous high temperature and drought,and the inappropriate selection and timing of pesticide applications.The prevention and control strategies of enhancing monitoring and early warning,adhering to scientific control,and strengthening technical guidance and technical reserves were proposed to provide a scientific foundation for the rational and safe management of weeds in rice fields.
