玉米田杂草综合防控措施探究

Research on Comprehensive Control Measures of Weeds in Corn Field

本文综述了国内外玉米田杂草研究现状及群落动态变化,并探讨不同耕作方式、灌溉方式、耕作制度等综合防控措施对玉米田杂草群落变化的影响,指出合理的杂草综合防控措施能改善玉米与杂草之间的关系,有效控制一些优势杂草的发生,可维护玉米田杂草生物多样性和生态平衡.随着农业可持续发展的实施和深入,结合地方特点了解玉米田杂草群落结构的变化趋势以及优势杂草种群的确定是今后研究方向的重点和难点,能够有效减轻杂草对除草剂的抗性演变,可为玉米高产高效栽培奠定理论基础.

This article reviews dynamic changes of weed communities in corn fields at home and abroad.The present study explored the impacts of different farming methods,irrigation methods,farming systems and other field management measures on the characteristics of weed communities in corn field.It was pointed out that rea⁃sonable comprehensive control measures of weeds can improve the relationship between corn and weeds,effective⁃ly control the occurrence of some dominant weeds,and maintain weed biodiversity and ecological balance in corn field.With the implementation and deepening of sustainable agricultural development,understanding the varia⁃tion tendency of weed species and the determination of dominant weed species in combination with local charac⁃teristics are the critical and basic process for further research.It can effectively reduce the evolution of weed re⁃sistance to herbicides and lay a theoretical foundation for high-yield and high-efficiency corn cultivation.
