旋耕刀盘逆转旋切被认为是一种在压实土壤中有效的开沟作业方式,对于提高果园机械化程度具有重要意义。目前,对该类型装置研究多以大田开沟及浅耕松碎土作业为主。为探讨压实、深切条件下土壤的破碎及排抛问题,围绕逆旋开沟机械-土壤耦合作用机理,从土壤剪切破坏模式及其影响关系、旋耕刀—土壤互作机理及分析模型的建立、土粒团的运动力学分析与建模、逆切旋耕刀结构优化与减阻降耗等4个方面进行综述,指出了现有（理论）研究存在的主要问题,讨论了土粒高效排抛的基本要求,分析了可能影响压实土壤旋切开沟作业性能的关键因素及其主要研究方法。

Reverse cutting of rotary cutter is considered to be an effective way of trenching work on compacted soil, which is of great significance to improve the mechanization degree of orchard. In order to discuss the problem of crushing and dumping of soil under compaction and deep conditions, this paper focusing on the mechanical-soil coupling of reverse ditching and ditching mechanism, provides a brief review of current researches from the following four aspects： the mode of soil shear failure and its influences, the establishment of rotary tiller-...
