纤维比强度气象生态模型的研究

Model of Meteorology and Zoology on Cotton Fiber Strength

在前人的研究基础上,利用多个试验的结果,论证了铃期日均温、日最高温度、相对湿度是影响纤维比强度的关键因子,明确了品种遗传因子在最终的纤维比强度形成中所起的决定作用。参考了前人的比强度是多个棉纤维品质指标中受环境影响变异性最大的指标的研究结论,提出了比强度多因素气象生态模型多个模型形式。利用试验结果进行模型的拟合并进行了模型检验,确定了最高温度和相对湿度交互作用的模型为最佳的比强度模型。模型的形式为:STH=STHs×AMTRHSTH,AMTRHSTH=2.6384×ARMHT+0.0261。模拟值与观测值1:1直方图符合度好,MRSE为1.0282cN/tex,证明了模型具有较好的预测性和较高的精度。

Based on existential research and data of a few experiments, it is proved that boll period average daily temperature , daily maximum temperature, daily relative humidity are pivotal factors effecting fiber strength, and varietal strength is crucial factor effecting ultimate fiber strength. Taking a reference that fiber strength is the easiest factor which are influenced by environment, we suggest a few models of fiber strength which are composed with more meteorology and zoology factor, and make simulated models and make to test for the models, and get the best model about daily maximum temperature and daily relative humidity, and the model is STH=STHs×AMTRHSTH,AMTRHSTH=2.6384×AMT/RH＋0.0261, The two RH inosculate approximately in simulated values and observed values in 1：1 bar charts. RMSE between them is 1.0282 cN/tex. The result showed that the model was accurate and applicable under different conditions.
