摘　　要：为准确模拟烟草叶片生长发育进程,实现烟叶精准可控生产,连续两年设置不同移栽期田间对比试验,利用Richards方程建立基于不同尺度的烟草下、中、上部叶面积变化动态模型,并分析不同模型的模拟精度。结果表明,烟草各部位叶片叶面积变化动态模型均符合典型“S”型生长曲线特征,有效积温模型对下、中部叶片生长的模拟效果优于生长时间模型,而对上部叶片生长的模拟效果较差;温光效应模型对各部位叶片不同条件下生长进程的模拟精度均高于有效积温模型与生长时间模型,具有更高的普适性;各部位叶片最终叶面积随移栽期推迟呈现先增加后降低的规律,下、中部叶片生长速率随移栽期推迟呈现加快规律,而不同移栽期上部叶的生长速率近似;推导获得各部位叶片缓增期、快增期、稳增期的温光效应值,为精准预测叶片生长提供参考。In order to accurately simulate tobacco leaf growth and development process,and realize the accurate and controlled production of tobacco leaves,field experiments of different transplanting date treatments were carried out for two years to establish dynamic models of changes in lower,middle and upper leaf areas based on different scales using the Richards equation,and the simulation accuracy of different models was analyzed.The results showed that the dynamic model of various parts of tobacco leaf area change conformed to the characteristics of typical“S”type growth curve.The effective accumulated temperature model had better simulation effect than the growth time model in simulating the growth of the lower and middle leaves,while had poor effect in simulating upper leaf growth.The simulation accuracy of the temperature and light effect model for the growth process of each part of the leaf under different conditions was higher than the effective accumulated temperature model and the growth time model,resulting in higher universality.The final leaf area of each part of the leaves increased first and then decreased with the postponement of the transplanting date.The growth rate of the lower and middle leaves showed an accelerating pattern with the postponement of the transplanting date,while the growth rate of upper leaves showed an approximate pattern in different transplanting dates.The temperature and light effect values of each part of the leaves during the slow-growth period,the fast-growth period,and the steady-growth period were derived to provide a reference for accurate prediction of leaf growth.
