邓恩桉耐寒抗霜冻能力较强,生长较快,是优良的纸浆用材树种。由于其开花结实较难,种子缺乏成为大力引种邓恩桉的瓶颈因素。试验研究结果表明,与以往邓恩桉嫁接技术相比,通过同砧长枝嫁接育苗新技术,能大幅度提高邓恩桉嫁接苗的成活率,达到80%左右。
Dunn Eucalyptus cold frost resistant capacity stronger, faster growth, is an excellent species of pulp timber. Due to its hard to flowering seed, lack of seeds to become a bottleneck in the introduction of Dunn Eucalyptus bottleneck factor. The experimental results show that, compared with the previous Dunn gum grafting technology, grafting seedlings through the new technology, can greatly improve the survival rate of Dunn Eucalyptus grafted seedlings, reaching about 80%.
