摘要
通过从美国相似气候区引进种子，在陕西境内开展多点育苗试验，认为美国黄松，特别是落基山黄松苗期生长迅速，抗逆性强，适生范围广，具有很好的引种前景。同时总结出一套美国黄松育苗关键技术。
Through introduction of Pinus ponderosa seeds from similar weather area in USA and mlti-sites nursery trial in Shaanxi,the results showed that one-year old seedings of P.ponderosa,especially P.ponderosa var.scopalorum growed well in nurseries and had a good tolerance to different weather conditions.Introduction of P.ponderosa in Shaanxi has a good prospects.The technigque for nurserying P.ponderosa is also summarized in this paper.
