Experiment on Afforestation of Three Tree Species on Islands of Zhoushan

Completely randomized experiment was carried out on afforestation of 1-year seedlings of Cinnamomum japonicum var. chenii, Schima superba and Pinus elliottii with different treatment of super absorbent polymers and compound fertilizer at poor habitat on island of Zhoushan, Zhejiang province. The result demonstrated that different treatment had influence on conservation rate among species, but little within the species. And it had great difference of height and ground diameter growth among species. Comprehensive evaluation by membership function on benefit of afforestation with different tree species and different treatment indicated that the best one was treated with 100g/tree compound fertilizer and 15g/tree super absorbent polymers.
