摘要
在人工造林过程中,培育壮苗是一个十分重要的环节,直接关系到造林的成败。马占相思引入我国的时间不长,国内外有关育苗施肥方面的研究尚少。所以,进行苗木施肥的研究工作十分必要。
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.
