| Abstract: | With the methods of regression and path analysis, the correlation be-tween the growth of magnolia officinalis and soil nutrient was studied. The regression equation of the tree hight and soil nutrient is Y1 = 3.128013 + 131.7013x2-0.4580875x3+0.14913x5(R = 0.9789***). The that of the breast diameter and soil nutrient is Y2 = -1.641872 + 2.227225xi + 0.1553113x5 (R = 0.9416***). Magnolia officinalis should be mainly app-lied with manure, nitric and potassic fertilizers. |
