农药使用效果与农药喷雾过程密切相关,农药喷雾过程的建模与仿真可弥补因植物生长周期差异、病虫害发生程度不同以及田间作业自然环境不可控等造成的试验研究困难.分析农药施用的抗性、再增猖獗、残留(resistance,resurgence,residue,3R)/效果、效率、生态(efficacy,efficiency,eco-environment,3E)/方法、模型、测试(method,model,measurement,3M),重点综述农药喷雾过程的雾化、输运、沉积等关键环节的模拟仿真研究状况.根据模拟仿真技术发展趋势,提出农药喷雾半实物仿真系统设计的建议,并提出雾化模型及新型喷头雾化机理、群体农药雾滴多相流场模拟、靶标定制与识别模型、综合农药雾滴飘移模型、植物生长模型与农药喷雾系统耦合等建议,以促进原创农药精确喷雾技术研究和高质量植保机械研发.
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.
