小麦叶面积指数和产量空间结构性分析

Spatial Structure of Leaf Area Index and Yield of Wheat

运用地统计学和相关分析法探讨了小麦叶面积指数与产量的空间分布及关系。结果表明,小麦叶面积指数与产量有中等变异和较好的空间结构特征。它们的相关系数为0.692,表现出显著的相关性,说明可以通过对叶面积指数的合理调控来提高小麦的产量。同时也为通过小麦的叶面积指数进行估产提供了一定的依据。

Spatial distributions and relationship between wheat leaf area index and yield were analyzed using geostatistics and correlation analysis methods. The results showed that wheat leaf area index and yield had intermediate variability and good spatial structure characteristics. Wheat leaf area index was closely related to its yield with their correlation coefficient being 0. 692. It indicated that the yield of wheat could be increased by rational regulation of leaf area index. Meanwhile, it offered basis for the estimation of wheat yield by leaf area index.
