基于物联网的病虫害绿色防控系统研发与应用

Development and Application of Green Pest Control System Based on IoT Technology

为减少农药施用量、发展病虫害绿色防控技术,保障农产品质量安全,基于物联网技术,结合臭氧灭菌防病、光源诱导除虫、作物健康识别和病虫害辨识预警等技术,研发了设施蔬菜病虫害绿色防控系统,主要由多功能植保机和信息管理系统组成。结果表明,绿色防控系统下草莓白粉病发病率较常规施药法降低27.7%,草莓产量提高19.8%,具有显著的草莓白粉病防控效果和增产潜力。同时,系统的预警服务、多方式消杀、远程控制和智能托管等功能有效缓解了我国植保技术装备落后、过度依赖农药使用、劳动力结构性短缺和维保运营困难等问题。系统的应用在一定程度上实现了设施蔬菜病虫害防治的绿色化、专业化和智能化。

In order to reduce pesticide application,develop green pest prevention and control technology,and ensure the quality and safety of agricultural products,a green pest prevention and control system was designed which composed of multi-functional plant protection machine and information management system,for facility vegetables based on the internet of things(IoT)technology,and combined with ozone sterilization and disease prevention,light source induced pest control,crop health identification,pest identification and early warning and other technologies.The results showed that under the green control system,the incidence rate of strawberry powdery mildew decreased by 27.7%,and the average yield of strawberry increased by 19.8%compared with the conventional application method,which had significant effect on powdery mildew control and potential of strawberry yield increase.Meanwhile,the functions of system early warning service,various disinfection and sterilization methods,remote control and intelligent trusteeship had effectively alleviated the problems of backward plant protection technology and equipment,excessive dependence on pesticide use,structural shortage of labor force,and maintenance and operation difficulties in China.The application of the system realized the greening,specialization and intellectualization of vegetable pest control in facilities to a certain extent.
