摘要: 为研究蝴蝶兰生长发育与环境积温之间的关系,运用纸片法、校正系数计算和线性回归分析法对蝴蝶兰叶面积计算公式进行优化,进而建立蝴蝶兰叶片生长速率曲线,并对曲线进行拟合和分析。研究结果表明,蝴蝶兰营养生长期间叶片总面积S 与积温T 呈二次函数关系,数学模型为S=0.043T2+21.36T+215.60。生长模型能较好地反映蝴蝶兰叶片营养生长期内的生长动态变化。运用生长模型对蝴蝶兰叶片生长量进行生长曲线的拟合和分析是可行的。

Abstract: In order to study the relationship between the growth rules and the accumulated temperature of Phalaenopsis, paper disk method, correction factor calculation and linear regression analysis were applied to optimize the method of Phalaenopsis leaf area estimation, then the growth rate curve established was analyzed and fitted. Based on that, the relationship between the growth curve and the accumulated temperature of Phalaenopsis was analyzed. The result showed that the growth model between the leaf area (S) and the accumulated temperature (T) was a quadratic functional relationship, S=0.043T2 21.36T 215.60. The growth curves were appropriately fitted with the growth dynamic change during Phalaenopsis vegetative growth period. It is feasible to analyze and fit the growth curve of the Phalaenopsis using the growth models.
