Weeding is a key link in agricultural production. Intelligent mechanical weeding is recognized as environmentally friendly, and it profoundly alleviates labor intensity compared with manual hand weeding. While intelligent mechanical weeding can be implemented only when a large number of disciplines are intersected and integrated. This article reviewed two important aspects of intelligent mechanical weeding. The first one was detection technology for crops and weeds. The contact sensors, non-contact sensors and machine vision play pivotal roles in supporting crop detection, which are used for guiding the movements of mechanical weeding executive parts. The second one was mechanical weeding executive part, which include hoes, spring teeth, fingers, brushes, swing and rotational executive parts, these parts were created to adapt to different soil conditions and crop agronomy. It is a fact that intelligent mechanical weeding is not widely applied yet, this review also analyzed the related reasons. We found that compared with the biochemical sprayer, intelligent mechanical weeding has two inevitable limitations: The higher technology cost and lower working efficiency. And some conclusions were commented objectively in the end.
除草是农业生产中的关键环节。智能机械除草被认为是环保的，与人工除草相比，它极大地减轻了劳动强度。然而，智能机械除草只有在多个学科交叉融合时才能实现。本文综述了智能机械除草的两个重要方面。第一个方面是作物和杂草的检测技术。接触式传感器、非接触式传感器和机器视觉在支持作物检测方面发挥着关键作用，它们用于引导机械除草执行部件的运动。第二个方面是机械除草执行部件，包括锄头、弹齿、指状部件、刷子、摆动和旋转执行部件，这些部件是为适应不同的土壤条件和作物农艺而设计的。事实上，智能机械除草尚未得到广泛应用，本综述还分析了相关原因。我们发现，与生化喷雾器相比，智能机械除草有两个不可避免的局限性：技术成本较高和工作效率较低。最后对一些结论进行了客观的评论。
