摘要
以有效积温为自变量,以叶片面积、叶片日龄和叶片数量为依变量建立苹果叶片生长模型。该模型包含有效积温子模型、单叶面积子模型、单枝叶面积子模型、单枝叶片日龄子模型、单枝叶片数量子模型和单树叶片生长子模型。通过D e lph i程序将各子模型联接,逐日计算单树叶片总面积、单树叶片日龄和单树叶片总数量。对田间实测数据与模型模拟数据进行相关性分析,以检验模型的准确度。结果表明,相关系数分别为0.997,0.972和0.974,说明该模型结构合理并具有较高的准确度。
The simulative models for the growth of apple leaf,including sub-model for an effective accumulated temperautre, for leaf area, for leaf area of single branch,for leaf age of single barnch, for leaf quantity of single branch and for leaf growth of single tree,were developed with effective accumulated temperautre,leaf single area branch,leaf age and quantity of leaf. The model was composed of sub-models which coupled with programming language-Delphi ,and worked out leaf area ,leaf age and quantity of leaf. The validation of the model with the data obtained from field and data from simulated model was analysed by correlation. The result was that index of correlation were 0. 999 7,0. 972 and 0. 974,indicating that the model was of rational structure and higher accuracy.
