摘要
在广东省西江林场的7种阔叶树种幼林内设置标准地,对其幼林期的生长表现进行研究。结果表明:米老排和灰木莲的地径、树高及冠幅与树高显著相关,地径与冠幅相关不显著;西南桦、火力楠和降香黄檀的地径、树高、冠幅三者间都显著相关;黑木相思的地径与树高及冠幅显著相关,冠幅与树高相关不显著;红花荷的地径、树高、冠幅的生长均无显著相关;米老排和西南桦为速生树种,是首选的推广树种,灰木莲、火力楠和黑木相思生长速度中等,而降香黄檀和红花荷为早期慢生树种。
The growth pattern of seven young broadleaf plantation Mytilaria laosensis,Betula alnoides,Manglietia glauca,Michelia macelurei,Acacia melanoxylon,Dalbergia odorifera,and Rhodoleia championi plantations was studied in standard plot of Xijiang River Forest Farm in Guangdong Province.Based on the results of cluster analysis： There are significant relation in basal diameter with tree height,and crown width with tree height of M.laosensis and M.glauca,and no significant relation in basal diameter and crown width.There are significant relation in basal diameter,tree height and crown width of B.alnoides,M.macelurei and D.odorifera.There are significant relation in basal diameter with tree height,and basal diameter with crown width of A.melanoxylon,and no significant relation in crown width and tree height.There are no significant relation in basal diameter,tree height and crown width of R.championi.The fast-growing trees were including M.laosensis and B.alnoides,which is the first choice to popularize;species growing with medium speed were including M.glauca,M.macelurei and A.melanoxylon;slow growth trees were including D.odorifera and R.championi.
