| 摘 要： | 以无性系DH3229、EC14、C6、巨桉、尾叶桉U6为参试品种,对参试品种3年生林的各项生长指标、抗逆性指标等进行了系统观测、评价。其结果表明,桉树耐低温寒害、耐高温干旱是重庆地区抗逆性状的核心指标,DH3229速生丰产树种可作重庆西部低海拔生态区域的优良种源,其无性系种苗可用于重庆地区退耕还林、速生丰产林、园林绿化。本项研究结果扩大了尾巨桉DH3229的种植范围。

| Abstract: | The 3 years old plantations of the clonal DH3229,EC14,C6, Eucalypt us grandis and E. urophylla U6 were observed and evaluated systematically from growth, resistance and so on . The results indicated those eucalypt clones cou ld resist the low temperature and drought which were two key resistances for tre e in Chongqing. The fast-growing and high-yielding species DH3229 was good f or low-altitude region in the western Chongqing,and its seedling could be use d to return the grain plots to forestry and build the fast-growing and high-yi elding forest and afforest garden in Chongqing. This study results were help to spread planting region of urophylla×E.grandis ‘DH3229’. |
