摘　　要：概述了国内外杂草与棉花竞争作用的研究进展和现状,归纳总结了杂草种类、杂草密度及杂草与作物的不同共生期对棉花产量、生长发育、品质、农事操作等影响。但现有研究主要集中在棉花最终产量和最终生长指标的分析上,而对棉花生长发育动态影响,尤其是内在机制的研究还比较少。因此,进一步细化研究棉花生长发育动态的形态指标和生理生化指标及与环境之间的关系,才能全面分析杂草与棉花的竞争作用,探明棉花响应杂草竞争胁迫的内在机制。Recent developments and the current status of research on the competition between cotton and weeds are summarized,including the influence of weeds on cotton production, growth, quality and farming operations. The main measures used to reflect the competitive relationship between weeds and cotton include the species composition, density and competition period,and researches have focused on analyzing the final yield and growth indicators of cotton. However, studies on the inherent mechanism of competition between cotton and weeds are scarce. Thus, it is essential to clarify the morphological changes in cotton and explain the physiological and ecological mechanisms of the cotton response to weed stress on both the external environmental and internal physiological levels, and then further explore the variation mechanism of competition between cotton and weeds.
