摘要
为研究彰武松早期生长特性，对彰武松优树和优良型樟子松进行嫁接对比试验。研究表明，彰武松树高生长量显著地高于优良类型樟子松，１９９５～１９９７年３年彰武松的平均树高生长量是优良类型樟子松的１５６６％；在不同立地条件、不同年份，彰武松的树高生长量也有显著差异；通过对早期生长的彰武松生理指标进行测定，反映出彰武松比樟子松更抗旱。
This paper involves comparison with selected Mongolian pine in some early growth characters of Zhangwu pine. Study on grafts of the two kinds of young trees indicates that Zhangwu pine performs better than Mongolian pine in growth. The mean height growth of former, which was 156 6% of latter, increased remarkably high during 1995-1997. However, the height growths varied under different site conditions and climates. Through measuring the physiological indices to drought resistance, we concluded that Zhangwu pine has higher drought resistant capacity than Mongolian pine.
