Abstract: Weeding is an important link in fruit tree management. Timely and effective weed removal is conducive to reducing orchard pest and disease infection, improving fruit yield and fruit quality, and increasing orchard economic benefits. Mechanical weeding has the characteristics of low energy consumption, safety, high efficiency and green environmental protection, which are the current research hotspot and the direction of fruit tree management. This paper reviews and summarizes the current research status of weeder at home and abroad from the aspects of suspension traction type, self-walking caterpillar type and intelligent type, and expounds the research progress of key components such as cutting device and copying device of orchard weeding equipment, as well as innovative breakthroughs in key technologies such as navigation and obstacle avoidance. There are some problems in Chinas orchard mechanical weeding equipment, such as poor integration of agricultural machinery and agronomy, low level of R & D and manufacturing, low degree of intelligent mechanization, and insufficient application of high and new technology. It is pointed out that the development of agricultural machinery and agronomic integration technology is an important driving force to promote the application upgrade of intelligent weeding equipment and improve the management level of orchards, and it is clear that Chinas intelligent weeding robot is entering a period of rapid development, and it is also a key opportunity for China to quickly follow up the international leading technology. This provides suggestions for technological innovation, performance improvement and equipment research and development of orchard weeding machinery in China.
