"Orchard Air-Assisted Sprayer with Surrounding Airflow and Pesticide Recycle " is a standardized orchard oriented intelligent application of mechanical equipment developed by students themselves. With the laser sensor and other techniques, sprayer can realize intelligent detection and decision-making basing on variable application. The airflow surrounding system independently designed by the team makes the pesticide liquid more evenly attached to the inner chamber of the fruit canopy, the back of the leaf surface and other areas with frequent diseases and insect pests, which greatly improves the efficacy. The pesticide recycle system minimizes potential safety hazards to human and animal and reduces environmental pollution caused by the floating loss of pesticides. In addition, the sprayer can adjust the width and height of its gate air duct to suit the application requirements of different planting patterns, which has the advantages of strong applicability, good prevention effect and high intelligence.

The program has lasted one year since November last year with a series of competitions and selections under the guidance of Qiu Wei, Zhao Yuhui, Ding Qun. In addition, Tan Zhiyun, Shi Xuegang, Li Kunquan offered help from the aspects of topic selection, team member optimization, defense drills, text improvement and promotion, and so on.
