摘要
为寻找筛选适合肇庆桉树林分改造的替代树种,通过对广东肇庆大南山林场营造及2年的试验观察,并对由广东省林业科学研究院提供的20种阔叶树种种植的保存率、树高和地径(粗生长)等指标进行早期生长表现调查。结果表明,树高、地径和生长量存在显著差异;10个样点阔叶树种保存率达90%以上,适宜在大南山林场乃至肇庆地区种植;青皮、红锥和火力楠3种阔叶树表现最好,其高生长和粗生长均达到最大值,可作为替代桉树改造的速生替代树种;其次土沉香、扦插苗木荷、蓝花楹、山杜英、楠木、火焰木、樟树、木荷、灰木莲、铁冬青、无患子和枫香等阔叶树种可推进桉树改造,是可供优选的替代树种;红花油茶、阴香、异木棉、实生荷木、风铃木、格木和乐昌含笑7个阔叶树种生长表现较缓慢。
In order to find and select alternative tree species suitable for the sub-transformation of Eucalyptus forest in Zhaoqing,the early growth performance of 20 broad-leaved tree species provided by Guangdong Academy of Forestry was investigated through the construction of Zhaoqing Dananshan Forest Farm and two years of experimental observation,and the preservation rate,tree height,and ground diameter(coarse growth)of 20 broad-leaved tree species provided by Guangdong Academy of Forestry Sciences were investigated.The results show that there are significant differences in tree height,ground diameter and growth amount.The preservation rate of broad-leaved tree species in 10 samples is more than 90%,which is suitable for planting in the Dananshan forest farm and even in Zhaoqing area.Three broad-leaved trees,Green Bark,Red Cone and Fire Nan,performed best,with high growth and coarse growth reaching the maximum,which can be used as a fast-growing alternative to eucalyptus transformation.Followed by soil agarwood,cuttings of wood lotus,jacaranda,mountain duying,nan wood,flame wood,camphor tree,wood lotus,ash lily,iron holly,wu zi,maple and other 10 kinds of broad-leaved tree species are to promote eucalyptus transformation,is the preferred alternative tree species.There are 7 broad-leaved tree species,namely safflower oil tea,yinxiang,isocupine,shisheng lotus,bluebell,gemu and Lechang hanxiao,and the growth performance is relatively slow.
