Abstract:

In recent years, the damage caused by weeds in paddy fields in Zhejiang Province has continued to intensify, becoming a key limiting factor affecting stable and high-yield rice production. To clarify the current characteristics of weed infestations and develop effective management strategies, this study conducted a systematic survey of 2,883 paddy fields across 11 prefecture-level cities in Zhejiang Province from 2020 to 2024. The research focused on analyzing weed community composition, the severity of damage, and its underlying causes. By integrating these findings with the practical realities of rice production in Zhejiang, we propose region-specific comprehensive management recommendations, aiming to provide a scientific basis for advancing sustainable weed control in paddy fields.

Key words: rice, weeds, occurrence characteristics, management strategies

摘要：

近年来，浙江省稻田杂草危害持续加重，已成为影响水稻稳产高产的关键限制因子。为明确当前草害发生特点并制定有效治理策略，本研究于2020—2024年对浙江省11个设区市共2 883块田块进行了系统调查，重点分析杂草群落组成、危害程度及成因，并结合浙江省水稻生产实际，提出具有区域针对性的综合治理建议，以期为推进稻田草害可持续治理提供科学依据。
