水稻叶面积分布构成因子的数值模拟

Numerical Simulation on Components of Leaf Area Distribution in Rice

叶面积分布是水稻株型研究的重要内容。通过机理分析建立了叶面积指数和叶面积分布模型,利用田间试验数据检验模型,通过数值模拟探讨节间距对叶面积分布影响的机理。模型检验效果良好,数值模拟结果可信,能为叶面积分布的优化提供理论基础。

The distribution of leaf area is an important content in rice plant type research. In this study, the leaf area in- dex and leaf area distribution model was established by mechanism analysis and was tested by field trial data, and then the effect mechanism of intemode distance to leaf area distribution was investigated through numerical simulation. The results showed that the model checking effect was good and numerical simulatian results were credible, which could provide theo- retical basis for the optimization of leaf area distribution.
