摘　　要：以舒兰响水林场花曲柳种源种子为材料,进行不同育苗密度比较试验,结果表明:90株·m-2密度的平均苗高、平均地径、平均主根长、平均侧根数分别为16.8 cm、0.60 mm、13.5 cm和14条,120株·m-2密度的分别为19.7 cm、0.45 mm、11.9 cm和11条,150株·m-2密度的分别为23.4 cm、0.35 mm、8.5 cm和9条。前两种密度苗木质量均达到吉林省地方标准Ⅰ级苗标准。Comparison experiment of different seedling density was carried by choosing the seed of Fraxinus rhynchophylla provenance of Shulan xiangshui forest center as the material.The result showed that the average height, average ground di-ameter, average root length, average number of lateral roots of 90 plants per square metre was 16.8 cm, 0.60 mm, 13.5 cm and 14, respectively.The 120 plants per square metre was 19.7 cm, 0.45 mm, 11-9 cm and 11, respectively. The 150 plants per square metre was 23.4 cm, 0.35 mm, 8.5 cm and 9, respectively.The seedlings quality of former two densities reached Ⅰgrade seedling standard of local standard in Jilin Province.
