摘　　要：为探索不同粒径配比松树皮对油松生长发育的影响,并找到适合油松生长的不同粒径的最佳含量比例,本研究对不同粒径含量的松树皮基质的物理性质变化情况和油松的生长情况进行比较。结果表明：5个处理基质的容重、孔隙度等物理性质比较稳定,且栽培前后的各项物理指标均满足理想基质的要求;综合油松生物量、生长指标、生理指标等分析,配比方案T4较好,即按照粒径大小2-5 mm∶0.5-2 mm∶〈0.5 mm为1∶3∶1比较适合栽培油松。To explore the influence of different size ratio of pine bark on the growth of Pinus tabulaeformis, and find a suitable ratio for pine tree growth. In the paper, the physical properties of content different size of pine changes were studied and the growth of Pinus tabulaeformis was compared. The results showed that the results showed that the physical properties of five treatments were stable and the various physical indexes before and after cultivation could meet the requirements of ideal matrix. Comprehensive Pinus tabulaeformis growth index, proportion plan T4 was better, namely according to the particle size 2-5 mm： 0.5-2 mm： 0.5 mm for 1：3：1 was suitable for cultivation of Pinus tabulaeformis.
