【摘要】 介绍温室黄瓜生长动态模拟系统的设计思路、模块划分和各模块的主要功能 以通过实验得到的黄瓜光合作用数学模型及不同生育阶段中干物质分配比例等建模所需的作物参数为基础,运用积分的方法,进行黄瓜干物质增长量和在各器官中的分配的逐日模拟 研究表明:用Delphi开发的温室作物模拟模型比较简洁,易于实施;模拟值比实际值略高,误差在4 7%～14 8%之间,基本达到了预期的效果;如果进一步在模型中加入水肥等因子修正参数,则可以达到更高的精度更多还原

【Abstract】 We introduce the design methods,model partition and the function of each part in the dynamic simulated growth system for cucumber greenhouse growth Based on the parameters needed in the dry substance partition model and the mathematical model of cucumber photosynthesis procedure, we use integral method to simulate the dry substance increasing weight and the partition in each apparatus every day The results suggest that the model developed by Delphi is compact and can be realized easily The simulated data are greater than the actual parameters, and the error is between 47% ～148% If adding the modifying parameters such as water and fertilizer, the model can reach higher precision更多还原
