Effects of Different Substrates on Nutrient Content in Leaves of Pinus bungeana
In this study,6 experimental groups were set up in Weihe River Basin of Xiaolong Mountain to evaluate the contents of N,P and K elements in the leaves of Pinus bungeana in growing and resting stages under different substrates,and compare the effects of different substrates on the nutrient contents of Pinus bungeana leaves.In the growth stage of Pinus bungeana,the content of N and P in leaves of treatment Group B was relatively high,4.21 g/kg and 0.22 g/kg,respectively,and the content of K in leaves of treatment Group D was relatively high,0.81 g/kg.In the resting stage,the contents of N and P elements in leaves of Group B were relatively high,3.35 g/kg and 0.12 g/kg,respectively,and the contents of K elements in leaves of Group D were relatively high,0.48 g/kg.Treatment Group B had higher content of N and P elements in both growth and resting stages,and treatment Group D had higher con-tent of K elements in both stages.
