Abstract: In order to improve the efficiency of fruit picking and fruit tree pruning in hilly area, a small-scale orchard electric operation platform was developed based on pid control algorithm theory.The platform has the advantages of simple structure and convenient operation.The results of field experiments show that the platform has stable performance and strong endurance, and can be used in 0-10 slope orchard for high-altitude farming.The pruning efficiency can reach 4.5 times of pure manual pruning efficiency,which meets the agricultural requirements of orchard operation and improves the operating efficiency of orchard Labor cost saving.
