通过对鲁东红富士苹果园土壤有效养分与产量、品质之间关系的研究,得出的主要结果如下:红富士苹果园土壤有机质、碱解氮、速效磷、速效钾与产量均呈一元二次回归关系,其回归方程式分别为:Y=-453.94x2+3293.8x,y=-0.1516x2+43.943x,y=-0.248x2+62.28x和 y=-0.1436x2+42.727x;R2分别为0.2893,0.045,-0.4222和-0.1328。
The main results obtained from the relationship between soil available nutrients, yield and quality of Ludong Red Fuji apple orchard were as follows: The contents of soil organic matter, available nitrogen, available phosphorus, available potassium and yield in Fuji apple orchard were all the same The regression equation is: Y = -453.94x2 + 3293.8x, y = -0.1516x2 + 43.943x, y = -0.248x2 + 62.28x and y = -0.1436x2 + 42.727x respectively; R2 are respectively 0.2893 , 0.045, -0.4222 and -0.1328.
