| Abstract: | The method of orthogonality was used to fertilize natural masson pine forest in Majiang oounty, Guizhou province. Results showed that fertilization had good effect on forest, especially on tree volume. At the seventh year after fertilization, the average volume increased by 32.3% compared with the control. Among the N, P and K fertilizers, P fertilizer was the best one for the forest. The optimal combination was N2P2K2, |
