Abstract

Abstract:

The effect of pesticide application is closely related to the pesticide spraying process. The modeling and simulation of pesticide spraying process can solve the difficulties in field experimental research caused by the difference of plant growth cycle， the different occurrence of pests and diseases， and the uncontrollable natural field environments. According to the resistance， resurgence， residue （3R）/efficacy， efficiency， eco-environment （3E）/method， model， measurement （3M） of the pesticide applications， the modeling and simulation researches on the pesticide spraying process， such as atomization， transportation and deposition， were summarized and analyzed. The semi-physical simulation system of pesticide spraying was put forward and analyzed based on the development of simulation technology. Finally， several research suggestions were proposed to promote research on innovative precision pesticide spraying technology and R&D of high-quality plant protection machinery， such as establishing atomization model for carrying out the atomization mechanism of new nozzles， the multi-phase flow field simulation of mass pesticide droplets， the spraying target customization and target recognition model， the comprehensive pesticide droplet drift model， and the coupling between plant growth model and pesticide spraying system.

Key words: plant protection machinery, pesticide spraying system, modeling and simulation, development and prospects
