摘    要:为了提高塑料连栋温室的生产水平,以温室内热量平衡为理论基础,将温室黄瓜生长发育植物模型与栽培环境模型相结合,应用MATLAB进行了模拟计算,结果表明,该模型物理意义明确,便于数值模拟,且模拟结果与实验吻合较好。就土壤温度模拟而言,除地表情况外,回归曲线拟合信度高,其R2=0.8999,绝对误差在±0.85℃之内,平均相对误差9.1%;对回归方程y=ax+b,a与b的标准误差Sa=0.0352a/2,Sb=0.1033b/2。

Abstract:Based on knowledge of heat transfer and thermodynamics and the principle of energy balance,this research has established the simulation model of the environment which was combined with the growing model for cucumber production in the green house.The sinulated caculation was carried out in MATLAB environment,which was identical with the data of the experiments.As a result,the model was proofed with clear and definite significance in greenhouse environmental management and auto-control system.Taking the soil simulation model as an example,it wins a higher credit value with R2=0.8999,the absolute error being in ±0.85 ℃,the mean relative error being 9.1,and the standard error for the a and b being Sa=0.0352
Keywords:Multi-span greenhouse  Production environment  Simulation  Cucumber
