| 摘 要： | 分别将引自北美洲的4个种源柔枝松播种于4种不同配比的基质中（以表土混合基质为对照），进行容器育苗。通过测定4个种源1年生容器苗在不同基质中的8项形态指标和4项生理指标，筛选出最适基质是泥V沙：V泥炭：V蛭石＝3：5：2。通过分析基质理化性质与容器苗形态及生理指标的相关关系，发现基质的物理性质是影响柔枝松1年生容器苗生长发育的重要因素。 |

| Abstract: | A container seedling breeding experiment was carried out with seeds of four Pinus flexilis provenances introduced from North America by four types of mixed substrate with different proportions （surface soil substrate was used as control）. The most suitable substrate selected was B2 （30% sand, 50% peat, 20% vermiculite） through measuring eight growth indexes and four physiological indexes of the one-year-old container bred seedlings of the four provenances. The correlations between the physical and chemical characters of the different substrates and the morphological and physiological indexes showed that the physiological indexes of the substrates were the most important factors influencing the growth and development of the one-year-old Pinus flexilis container bred seedlings. |
