摘　　要：根据多年不同保护地栽培田间试验的结果,利用Origin 软件结合马铃薯生长发育的基本特点,提出了以发育生理日为驱动变量的光合产物在不同器官间分布的数值模型,方法简便,机理明确,模拟精度高.研究还给出了不同发育时期马铃薯不同器官的干物率变化模型,并依此推导出器官的鲜重模型,进行了马铃薯块茎产量的模拟,结果表明模拟值与实测值具有良好的一致性.Based on four-year field experiments in different cultivated conditions, by Origin software integrated with bio-mechanism of potato growth and development, digital models for photosynthesis products distribution in different apparatuses are submitted in this paper. These models are driven by the physiological development days and they are of easy usage, clear mechanism and high accuracy. This paper also provides models for dry-matter rate changes in different apparatuses and different development stages of potato. Depending on these models the simula- tion results of fresh weight in different apparatuses are obtained. The validation analysis shows that there is close relationship between simulated yield and observed yield.
