Abstract: In order to explore the orchard sprayer and its use technology for the standard orchards, 5 kinds of advanced orchard sprayers commonly used at home and abroad were screened on the basis of extensive investigation and investigation of plant protection machinery and the application technology from domestic and foreign standard orchard. The experimental research on the technical parameters such as atomization, deposition and drift of pesticides showed that FEDE type in the orchard sprayer, the distribution of fog between 0.4~2 m was more uniform; the distribution of 3WFX-400(W2)  in the tree crown was the better uniform, the coefficient of variation was the smallest, which was 18.3%;the ground loss of various types of sprayers was FEDE(W5) > the 3WG-1200A(W4) > SSA-E501DX(W1) > 3WFX-400(W2) > plant protection unmanned aerial vehicle(W3)(P<0.05). Above results provided reference for fruit growers to choose plant protection machinery and orchard sprayer manufacturers for product structure design and performance optimization.
