Abstract

Abstract:

This article dealt with the correlation between the nutrient contents of N,P,K,Ca,Mg,Cu,Zn,Mn,Fe in foliages and the height growth, current height growth, and the growth of DBH of young Chinese fir plantation during the first and second rotation grown under hill site conditions. Then the scientific basis was provided for increasing timber yield and preventing and curing soil fertility degradation from the angle of forest tree nutrition. The research results showed that there was a closely positive correlation between the growth of young Chinese fir plantation in the second rotation and the contents of N,P,Mg,Cu,Mn,Fe. The coefficient values of complex correlation was lower for the first rotation, compared with the second rotation, suggesting that there was not obvious influence of soil nutrient content on the normal growth of young Chinese fir plantation in the first rotation.

Key words: Nutrient content in foliage, Forest tree growth, Correlation coefficient, Chinese fir
