福建沿海山地引种柳窿桉和巨尾桉试验初报

Adaptability Analysis of Introducing E.saligna ×E.exserta and E.grandis ×E.urophylla to the Mountain Land with Mid and High Altitudes

通过柳窿桉、巨尾桉在连江长龙林场山地的造林试验，2年生（实际20个月树龄）柳窿桉树高、胸径分别达6．8 m、7．2cm。巨尾桉树高、胸径分别达7．2 m、8．1 cm。表明柳窿桉、巨尾桉在海拔500～600m土壤贫瘠的沿海山地也能快速生长。有一定适应性，但柳窿桉抗寒抗霜冻能力较差，引种时要慎重选择品种。

Abstract： Through the afforestation experiment of E. saligna ×E. ezserta and E. grandis ×E. urophylla in Lianjiang Changlong Forest Farm, 2-year-old （20-month-old in the fact） E. saligna ×E. ezserta tree height and dbh reached 6.8 m and 7.2 cm,the E. grandis ×E. urophylla tree height and dbh reached 7.2 m, and 8.1 cm, respectively, which showed that 2 ones could grow fast on the poor soil of coastal land with mid and high altitudes of 500- 600 m, they had a certain adaptability, but the former ability of anti cold and frost was bad, the species should be selected carefully.
