【摘要】 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。更多还原

【Abstract】 The test was configuring for the flower’s number of Winged bean with curvilinear 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.更多还原
