摘要
对13个柳桉种源速生性、适应性和抗逆性进行了测定与分析,并经多性状综合评判,选择出速生性和适应性强、耐寒性较强或中等,适合福建省中亚热带东部山地发展的柳桉优良种源有14435、13340、14508、14429、15011和13263等6个,5年生年平均树高和胸径生长量分别可达2.4m和2.2cm以上,其中前3个种源可耐-4℃左右的低温,可在该区重点发展,后3个种源可耐-3.5℃左右的低温,较适合在该区沿海或低海拔山地引种栽培。而14526、14507、14524和14054等4个种源,适应性较强、耐寒性强但速生性中等,可在该区较高海拔山地有选择地应用。
The measurement and analysis were conducted on fast-growing character, compatibility and adversity-resistance for 13 provenances of E.seligna. After comprehensively evaluation,the selected provenance with attributes of fast-growing, stronger compatibility and stronger or middle cold resistance include 14435、13340、14508、14429、15011 and 13263, they are suitable for further development in eastern hilly land of Fujian middle-subtropics. The average height and DBH of these six provenances are annual surpassing 2.4m and 2.2cm in 5 years respectively. The first 3 provenances can bear low temperature about -4℃,and they are suitable developed ; the latter 3 provenances can bear low temperature about -3.5℃, and they are suitable cultivated in land with low altitude or close to seaside in eastern hilly land of Fujian. But the provenances of 14526、14507、14524 and 14054 are stronger cold resistance and middle- growing, they are suitable planted in land with higher altitude.
