摘要
根据水稻群体茎数变化规律,本文提出了茎数变化的数学模型,并且将参数灰化,建立了灰色模型,提高了预测精度。本文还建立了4类品种的参数与气象条件、管理条件的相互关系子模型。
According to the tillering law of rice, we establish its forecast model. Inorder to improve its precision, we make the parameters grey in the model andestablish the grey model. Moreover, on the basis of experimental data, some sub-models of parameters are also put forward in this paper.
