低温对棉花纤维品质影响模型的研究

基于多个试验结果，论述了纤维长度与品种特性和气象生态因子的关系，认为棉纤维长度主要决定于品种特性，但也受气象生态因子的影响。基于以上结论，提出了体现品种遗传特性的分果节位的棉纤维长度的模型，和日最低温度和夜均温对纤维长度影响的修正模型。由这两个模型组成的拟合纤维长度的综合模型既强调了品种特性对纤维长度的决定作用，又体现了气象生态因子对纤维长度的影响作用。相应的模拟值与观测值比较表明，该模型具有较好的预测性。

Model of low temperature influence on cotton fiber quality

Based on data of a few experiments,relationship between cotton fiber length and variety character as well as meteorological and ecological factors is explained.The cotton fiber length is mainly determined by variety character but get influence from meteorological and ecological factors yet.On the basis of above conclusion,a cotton fiber length model reflecting branch node of veriety's hereditary feature and corresponding modified model considering influence of daily lowest temperature and mean temperature at night on fiber length are presented.The integrated model composed of above two models reflects main effect of cotton veriety and influence of meteorological and ecological factors simultaneously.Comparison between simulations and measurements shows that the model has a good predictability.
