摘　　要：根据5年不同方式的保护地和露地栽培田间试验,利用Oringin和SAS软件结合马铃薯生长的生物学原理,建立了马铃薯叶龄和叶面积系数变化的动态模拟模型,该方法简便,机理明确,模拟结果重演性强。本文还探讨了应用同位素示踪技术进一步发展作物群体发育的动态模拟,推进数字农业技术的途径。Based on five-year different protected and common cultivation field experiments and by using Oringin and SAS software intergraded with the principles of bio-mechanism, dynamic models of leaf age development and leaf area index change of potato were submitted. The simulated results showed that the methodology was of easy usage, clear mechanism and high accuracy. The approaches of using isotope tracing techniques to develop the crop population development simulation for digital agriculture were analyzed.
