摘要
研究了七叶一枝花的生长曲线方程及其拟合性,该过程应用了统计软件SPSS中非线性回归子程序,对其进行生长曲线拟合.同时对株高生长与外部形状的变化进行了跟踪记录并进行数据比较分析,进行数据时采用了logistic生长模型,对七叶一枝花株高生长进行了曲线方程拟合.其结果表明:曲线方程拟合度为0.992,很好地反应了七叶一枝花株高生长的趋势,且同时记录了七叶一枝花生长过程的外部形状的变化,从而为七叶一枝花高产栽培和良种选育提供第一手素材和有效的参考数据.
Studying on Paris polyphylla var. chinensis is the growth of a flower and its fitting curve equation and the process is applied in the statistical software SPSS nonlinear regression subroutine its growth curve. At the same time, plant height growth and changes in the external shape of the track record and comparative analysis of data, data used in the logistic growth model of height growth of a flower Paris polyphylla var.chinensis a curve fitting equation.The results showed that fit curve equation 0.992, respectively, so that response can very well spend a Paris polyphylla vat. chinensis height growth, and at the same time records the growth process of a flower Paris polyphylla var.chinensis external shape changes, so as to spend a high Paris polyphylla var. chinensis cultivation and breed for the first - hand material.
