摘　　要：以 1993～ 1994年的田间试验数据和同步的气候资料为基础 ,采用高斯方程 ,建立了以日平均气温为驱动变量 ,肥水满足条件下的马铃薯生育期的模拟模型。结果表明本模型不但具有较强的机理性和解释性 ,而且具有模拟精度高、预测性好等特点。本研究根据提出的模型用VisualBasic语言编程 ,使每日生态因子变化对马铃薯发育生理日的影响能够动态地表现出来 ,模拟结果具有很强的直观性 。Based on the field experimental data and simultaneously observed climatic data in 1993 and 1994,a phenology simulation model for potato development was established,at the perfect fertilizer and water conditions.The drove variable is daily average air temperature,and the basic model was Gauss equation. The simulation result showed that this model was of clear mechanism,explanatory,accuracy and prediction. This research was programmed with Visual Basic based on established model. Through the running user-friendly graphical interface potato developmental physiology date effected by ecological factors could dynamically be expressed. The simulation result was of very strong intuitiveness. This method completely overcame the shortage of simulation result express in crop production modeling.
