摘要
本文首先建立了建三江农场水稻单产变化的 Logistic模型 ,通过对模型的微分方程形式的离散 ,得一二次函数 ,进行回归分析 ,得出模型中参数的估计值 .对模型进行分析得出现阶段水稻单产的最大潜力和水稻增产速度最快的时间段 ,对于指导水稻生产 ,优化农业生产结构 。
In the paper the Logistic model of rice yield in one unit is established in JiangSanjian farm, by using the discrete formalization of Logistic model the quadric function is obtained, by regression analysis the parameters of the model is solved. By analyzing the model we get the maximum yield of rice and the optimally period of enlarging rice produce. This is very important for guidance agricultural produce and optimal industry structure.
