| 摘 要： | 小麦叶面积指数计算为群体绿叶与比叶面积的乘积，而绿叶重为其分配指数的地上部干重的乘积。建立了绿叶分配指数与生理发育时间之间的曲线关系。结果表明，模型能较好地模拟叶面积指数的变化动态，其平均相对误差小于10％。

| Abstract: | Leaf area index (LAI) of wheat was calculated as the product of the green leaf weight by specific leaf area, and green leaf weight as the product of its partitioning index by top weight. The curvilinear relationship between partitioning index of green leaf and physiological development time was established. The simulation results showed that the relative errors of predicted LAI were less than ten percent. |
