摘　　要：从美国引进黄松、班克松种子 ,以油松为对照 ,分别进行多点育苗 ,并营造对比试验林。 5年来对其生物生态学特性进行了详细的观测和对比分析。试验结果初步表明 :黄松和班克松在我省陇南等地区适应性强、生长稳定。5年生黄松平均树高为 0 .2 4m,平均地径为 0 .6 5cm;班克松平均树高为 0 .42 m,平均地径为 0 .71cm。班克松 5年生当年高生长平均为 10 .5 1cm,油松只有 7.5 8cm,地径生长也与油松接近。On the base of introducing seeds of Pinus ponderosa and Pinus banksiana, nursing and planting trial stands, its eco biological characters have been surveying during the period of trial. The results of trial for 5 years indicates: Pinus ponderosa and Pinus banksiana have strong adaptability and stable grow in Longnan distract of Gansu. The average height of 5 year Pinus ponderosa and Pinus banksiana are 0.24 m and 0.42 m respectively, and the average ground diameter are 0.65 cm and 0.71 cm respectively .The present average height growth of 5 year Pinus banksiana (10.51 cm) is higher than that of Pinus tobulaeformis (7.58 cm) , present ground diameter growth of the former is near to the later.
