摘　　要：为充分验证湿地松在曲靖市国有海寨林场的适生情况,为湿地松在海寨林场全场范围以及相似高海拔地区推广种植提供科学和现实依据,特选择海寨林场具有代表性立地条件的海寨林区进行湿地松引种造林,通过采用科学的造林方法和造林技术,湿地松的当年成活率达到了98%以上,3年后保存率也能保持在92%以上,3年林木地径生长量在7.8~8.9 cm,树高生长量在270~310 cm,由此可见湿地松成活率(保存率)达到验收标准,林木生长量正常,在引种项目区适应性优良,仅就初期成活率(保存率)和生长量来看能够在海寨林场全场范围推广种植,对相似高海拔地区种植湿地松具有现实借鉴意义。In order to fully verify the adaptability of Pinus Elliotti engelm in the State-Owned Haizhai Forest Farm in Qujing City,and to provide scientific and practical basis for the extension of Pinus Elliotti engelm in the whole area of Haizhai Forest Farm and similar high altitude areas,the introduction and afforestation of Pinus Elliotti engelm were carried out in the representative site of Haizhai Forest Farm.By adopting scientific afforestation methods and techniques,the survival rate of slash pine was over 98%,and the survival rate of Pinus Elliotti engelm can be kept above 92%after three years.The growth of diameter and height in three years are 7.8-8.9 cm and 270-310 cm,respectively.It has good adaptability in the introduction project area,and can be widely planted in the whole area of Haizhai Forest Farm only in terms of the survival rate and growth,which is of practical reference significance for planting Pinus Elliotti engelm in similar high-altitude areas.
