四棱豆开花特性的曲线方程配置研究

Study on Characteristic of Winged Bean Florescence with Logistic-growth Curvilinear

对四棱豆停止开花前的株高生长曲线进行了拟合,并对株高生长与开花数目变化进行了比较分析,采用logistic非线性生长模型对四棱豆开花特性进行了曲线方程配置。结果表明:曲线方程拟合度为0.990,能很好地体现四棱豆开花和生长特性,根据曲线方程计算得开花数目增加的拐点时间为出苗后的第99天,拐点花数目为70朵。

The test was configuring for the flowers number of Winged bean with eurvilinear equation by Logistic-non-linear growth model, the result indicated that： the R sequence value of the curvilinear equation was 0. 990 and it was fit for describing the characteristic of florescence and growth of Winged bean. We got a result the inflexion time were the 99th day after the produce buds; there are 70 flowers according to the curvilinear equation. In the study Logistic-growth curve model was estimated, the relation between increase of flower amount and growth of plant was analyzed.
