Abstract
In order to improve the pesticide application efficiency and reduce the agricultural chemicals lost in fruit trees spraying, an automatic target spraying system of canopy scanning identification based on the sprayer is designed in view of excess spraying and ineffective spray at trees gaps during traditional spray operation. The ultrasonic sensors are installed on the boom of the sprayer under profile modeling spray to detect the crop canopy. Based on the sensor signals, solenoid valves by side are used to control the switch of nozzles at the corresponding position. The experiment of target spray system is worked at the six year-old landscape tree. The results show that the target spray system can effectively save the amount of application pesticides compared with continuous spray. The target spray system can save pesticides 47.8% at the travel speed of 1 m/s for the gap rate 46.7% of landscape tree. Thus, the target spray system of the sprayer has good application value to the pest control of sparse fruit trees and other crops.
