摘　　要：为了研究水肥耦合对细根形成的影响,对水肥耦合条件下细根形态的变化进行了综述,分别通过细根形态主要指示指标:直径,根长,比根长在水肥耦合条件下的不同反应,来分析细根形态的变化规律和原因,并对细根形态的研究现状提出进一步的研究方向。In this paper, changes in fine root morphology under the conditions of the coupling of water and fertilizer are reviewed. Through the different reactions of fine roots, respectively, the main form of instruction indicators： diameter, root length, specific root length under different coupling of water and fertilizer conditions the reasons and the changes of fine roots morphology are analyzed and a further research direction is proposed according to the current research state of fine roots morphology.
