Early performance of growth variation among 11 broad-leaf tree species native to Nansha District,Guangzhou
The growth of height, diameter at breast height ( DDBH ) and canopy width ( Wcw ) of 11 native broad-leaf tree species which were planted in Guangzhou Huang Shan Lu Forest Park in 2008 were given monitoring research, and the neighboring Mallotus panicidatus' secondary forest and rhizosphere soil fertility of some tree species of experimental forest were studied. The results showed that: all tree species grew well, except Terminalia myriocarpa and Castanopsis faberi which were almost all dead for not adapted well. The height, DDBH and Wcw of Tetradium glabrifolium, Betula alnoides, Mytilaria laosensis and Elaeocarpus sylvestris grew quickly. Content of soil organic matter in the experimental forest was lower than in Mallotus paniculatus' secondary forest. But, for the effect of soil fertility improvement, Michelia macclurei and Mytilaria laosensis were the best, and the rapid growth' s Betula alnoides and Tetradium glabrifolium were better, and the soil fertility of Castanopsis faberi was the lowest. Preliminary result showed that Michelia macclurei and Mytilaria laosensis were good for soil improvement, and the fast-growing trees, Betula alnoides, and Tetradium glabrifolium, could provide effective increasing of forest coverage in the degradation hillsides.
