A Preliminary Study on the Application of Fertilisers on the Seedlings of Acacia mangium

Through studying and analysing the effects of fertilizationon the growth of the seedlings of Acacia mangium, application of phosphatefertilizer and inoculation of nodule bacteria are proposed in the paper. Application of nitrogen fertilizer in the too early stage or excessively used are unsuitable to the growth of young seedlings.In the pot culture experiment, application of different amount of phosphate fertilizer has known that it can increase the growth of height, canopy and ground diameter, biomass accumulation, nodule number and nodule dry weight, but the ratio of above ground dry weight/under ground dry weight can not be changed. Applying 100g phosphate fertilizer for each seedling is the best choice.
