Review on electric pruning equipments and technology in orchard

Pruning is a great part of orchard daily management,taking a great amount of labor force. Theorchard electric pruning shear has a great advantage in reducing labor intensity and cost because of itsconvenience and high cutting quality. On reviewing the research status of electric pruning shear in andout of abroad,it's classified into three kinds according to different transmission. The main parts of elec-tric pruner like blade,motor,reducer and battery are analyzed and summarized particularly on their de-velopment status and tendency. The shortages and technological difficulties of domestic electrical pruningshear have been directly pointed out and discussed,especially about blade,motor,reducer and battery.Finally,it is advised that the electric pruning shear should be developed towards more safety,multifunc-tion and higher cutting capacity,so that electric pruning equipments can play a more important role infruit production.
