摘要
利用回归分析、灰色关联度和层次分析方法建立了施肥量对农作物生长的数学模型 .该模型较好地模拟了N ,P ,K对农作物产量的影响 。
Some mathematical models are given about crop growth and fertilization quantity ,by using the methods of regression analysis, grey dependent degree and analytical hierarchy process.The models preferably simulated the quantity of production which is affected by nitrogen,phosphor and kalium.This has important significance to the fertiligation of crops.
