蔬菜产量氮肥效应预测的理论模型

Theoretic Model of N-Fertilizer Response Prediction on Vegetable Yield

本文构造了能够模拟蔬菜产量氮肥效应速率变化规律的函数模型，运用微分方程理论，得到了对蔬菜产量的氮肥效应进行预测的理论模型，并通过6个试验对所建理论模型进行了检验，取得了良好效果．

In this paper,a functional model that can imitate change law of N-fertilizer response rate on vegetable yield was built.Applying the theory on the differential equation,the authors obtained the theoretic model of N-fertilizer response prediction on vegetable yield,and the theoretic model was tested by the six experiments.The results are very good.
