温室蝴蝶兰生长动态模型设计与实现

Design and Implementation on the Dynamic Vegetation Model of Greenhouse Phalaenopsis

为了对温室蝴蝶兰生育过程的基本规律和量化关系有一个清楚的理解和认识,并对其生长系统的动态行为进行预测,从而辅助进行对蝴蝶兰生长和生产系统的适时合理调控,研究建立了以太阳辐射为基本驱动因子的温室蝴蝶兰生长发育动态模型,进一步开发出基于Windows XP的计算机模拟系统。模型系统采用C++ Builder6.0语言编程技术,主要包括太阳辐射、碳同化、干物质分配等重要模块,可以输出干物质积累量、光合作用率、叶面积指数、叶片数与花朵数等参数变量,具有较完善的功能,模拟系统在界面和功能上能够达到较好的统一。对山东省济宁市农业高技术园区温室内蝴蝶兰进行模拟检验分析表明,模拟结果与实测结果符合较好,模型系统可以动态预测蝴蝶兰光合产物积累量等重要变量指标,研究认为该模型系统是研究蝴蝶兰生长发育特性及优化管理的重要工具。

In order to understand and know about the basic principle and quantification relationship of greenhouse phalaenopsis during vegetating phase and forecast the dynamic action of vegetation system so as to assist reasonably regulating and controlling on the vegetation and production system of phalaehopsis real time, a dynamic vegetation .model of greenhouse Phalaenopsis is created on the solar radiation as the basic driving factor and a computer simulation system is developed on Windows XP system. The system mainly includes important modules such as solar radiation, carbon assimilation analysis and dry matter partitioning and so on which can output dry matter accumulated value, photosynthesis ratio, leaf area index, quantity of lamina and flower etc parameters and make the model have perfect functions. The computer simulation system uses C＋＋ Builder6.0 as the programming language that makes the interface and function of simulation system uniformed. The simulation experiment and analysis are carried out in the phalaenopsis greenhouse in the New and High Agricultural Technology Demonstration Gardens of Jining City, Shandong Province. The result shows that the simulated result is better fit with the experimental result. The model can dynamically forecast the accumulated quantity of photosynthesis production etc important index of phalaenopsis and it is an important tool to study the vegetation characteristic of phalaenopsis and optimized management.
