Effect of Microbial Fertilizer on Growth of Container Seedlings of Myrica rubra

In March 2010, 1-year grafted Myrica rubra seedlings were transplanted in containers. Experiments were conducted in May and July in the current year on application of different doses of microbial fertilizer to container seedlings, with no fertilizer as the control. The result demonstrated that microbial fertilizer promoted significantly the growth of container seedlings. The height growth of seedlings treated by different doses of fertilizer increased 19.6％ to 44.7％higher than that of the control, ground diameter by 14.3％ to 30.8％ and biomass by 13.9％ to 29.9％. The content of soluble sugar in leaves of treated seedlings were 26.36％ to 102.8％ higher than that in the control July to October. N, P and K in leaves, stems and roots of seedlings treated by microbial fertilizer increased significantly than that of the control.
