| Abstract: | In this paper, the growth of the seedlings and young trees of Finns massoniana are studied. The result indicates that the effectiveness of fertilization on the seedlings (are signicant. In this experiment, NO.3 (N1P3K3) is the best one with a under-ground biomass (dry weight) of 0. 575 g/seedling, which is 21.6% more than that of the check(0.473 g/seedling). Over two years after planting, the height and root diameter of the young trees fertilized by N1P3K3 are 2.63m and 2.54cm respectively, but those of the young check trees only 2.13m and 2.01cm. There is a significant difference between them,and the analysis shows that there is a positive correlation between the height and root diameter of young trees and the underground biomass of the seedlings. |
