Abstract:
Soil fertility and growth increment of Pinus massoniana Lamb. trees were monitored for 5 years in a young stand located in Fenyi county, Jiangxi Province. The results showed that the effect of fertilization with K was not evident, but that was better with P. The content of total P in soil in the second year, in the third year, and the fifth year after fertilization increased 18.2%, 18.1%, and 43.1% respectively, compared with control. The height, DBH and volume of forest trees in the plot fertilized with P yearly increased 3.0%, 16.7% and 9.7% comparing with control, suggesting positive effect of P fertilizer applied in the hill and mountainous districts with red soil.
Key words: Masson pine, Young stand, P fertilizer, Application effect of fertilizer
