单株幼龄苹果树修剪仿真研究

Simulation Research for Individual Young Apple Tree Pruning

修剪是果树生产中重要的技术手段,要想研究更加合理的修剪技术体系,就必须保证能够对修剪反应有准确、直观和及时的判断,而仿真模拟技术提供了这种可能。以幼龄苹果树为研究对象,采用不同修剪处理对比的方法,在田间试验的基础上,总结修剪反应规律,构建苹果树结构和修剪模型。在此基础上基于Qt框架和Open GL图形库,开发了单株苹果树修剪仿真软件平台。结合优化算法,通过仿真平台模拟了给定生产目标的修剪方案优化,优化结果对虚拟学习和实际生产提供了可视化指导。

Pruning is one of the important measures for fruit trees management. Different pruning methods have different effects on the growth of fruit trees. Research on the law of apple tree growth after pruning is of great significance to guide production. Apple tree,as a perennial,is quite complex in observation,modeling and calibration,which makes researches related quite a few. In order to study more reasonable pruning technology,judgment of pruning reaction needs to ensure the accuracy,intuition and timeliness and the simulation technology makes it possible. In this thesis,apple tree was taken as the research object,the data which was measured from the field experiment was analyzed,the law of pruning reaction was summarized and the structure model and pruning model of apple tree were built. The simulation software of apple tree pruning was established based on the Qt framework and Open GL graphics library. For a given production target,the simulation software of apple tree pruning provides an optimized solution of pruning through the optimal algorithm.
