摘　　要：为了筛选适合油松生长的松树皮不同粒径质量含量的配方,该研究进行了不同粒径配比的松树皮对油松生长指标影响的测定并做出综合评价。结果表明：松树皮按照2.0~5.0 mm、0.5~2.0 mm、〈0.5 mm 3种粒径等级复配,比例为1∶3∶1的松树皮作为基质,油松苗木品质指数最高为0.019 8,顶芽干重和生物量指标均最高,综合评判结果最好,可见1∶3∶1的松树皮基质最适合培育油松苗。To select the suitable pine bark size content formula for the growth of Chinese pine, the different size content on the growth of Chinese pine was compared. The results showed that particle size ratio of 1：3：1 pine bark which Chinese pine seedling quality index was highest, highest crown dry weight and biomass indexes, comprehensive evaluation results were best. Particle size ratio of 1：3：1 pine bark as the matrix, the growth conditions of Chinese pine were best.
