林木虚拟生长模型是应用计算机模拟树木在三维空间中的生长发育状况,而农药精确施用模型是应用计算机模拟农药按需定量喷施、与目标植物接触以及产生药效等一系列喷施作业情况。如果把两者耦合起来,将直观模拟出林木正常生长、受病虫害侵染、农药发挥效果、长势有所好转等一系列交互效果,可为调整植物保护策略、制定农药喷施方案和研制新型植保机械提供理论支持和技术支撑。文中分析了农林病虫害防治情况和农药精确施用的重要性,在综述国内外喷头雾化性能模型、沉降沉积模型(飘移模型)、施药量调节模型、雾化特性预测模型等农药施用模型研究现状的基础上,通过分析探讨两模型协同机理和林木虚拟生长模型及耦合模型实时性协同环境,提出了基于农药施用过程与防治药效的模型协同研究、基于林木形态结构模型的仿形对靶喷雾模型研究以及农药精确施用多模型交互协同研究的建议。
Tree growth model is the application of computer simulation tree growth and development in three-dimensional space, and the precise application of pesticide model is the application of computer simulation of pesticide spray on demand, with the target plant and produce a series of spray effect and other operating conditions. If the two are combined, a series of interactive effects will be simulated, such as the normal growth of forest trees, infection by pests and diseases, the effect of pesticides and the improvement of growth prospects, which can be used to adjust plant protection strategies, formulate pesticide spraying programs and develop new plant protection Machinery to provide theoretical support and technical support. In this paper, the status of pest and disease control in agriculture and forestry and the importance of precise pesticide application were analyzed. The status quo of pesticide application models such as nozzle atomization performance model, sedimentation sedimentation model (drift model), application rate adjustment model and atomization property prediction model Based on the analysis and discussion of the synergistic mechanism of two models and the virtual growth model of forest trees and the real-time collaborative environment of the coupling model, a model synergistic study based on pesticide application process and control efficacy was proposed. Based on the morphological structure model of the forest, Model research and the precise application of pesticides multi-model interactive collaborative research recommendations.
