以桉树皮为材料，通过对3种粒径桉树皮基质理化性质分析和苗木调查，研究不同粒径对基质理化性能和育苗效果的影响。试验结果表明：在育苗过程中，粒径<2mm的桉树皮基质理化性质相对更稳定，苗木生长量最大，育苗效果最好；粒径2~5mm和5~10mm的桉树皮基质理化性质变化较明显，而粒径5~10mm的基质孔隙性变化最大，化学性质不够稳定，粒径对育苗基质和育苗效果影响较大。

In order to investigate the influence of different particle sizes ofEucalyptus bark on physical and chemical properties of growing media and the effect ongrowth of Eucalyptusseedlings, this study was conducted involving Eucalyptusbark of three particle sizes. The results showed: the physical and chemical properties of Eucalyptusbark matrix of particle size <2 mmprovided media with the best physical and chemical properties and also provided for the best seedling growth. For media constituted with bark of particle sizes 2 ~ 5 mm or 5 ~ 10 mm, variationsin physical and chemical properties were more apparent, porosity changeswere larger, and the chemical properties werenot adequately stable. The particle size had a great influence on the mediaproperties and the growth of Eucalyptusseedlings.
