伞房属四个树种在广东的早期生长表现

文章分析了引自澳大利亚东部的伞房属4个树种在广东省的早期生长表现。3年生及5年生4个树种生长量的方差分析表明,不同地点、树种及地点与树种的交互作用在树高、胸径、材积生长上均表现出极显著的差异。3年生时,生长表现最好的是斑皮柠檬桉,平均单株材积0.007 191 m^3;德庆试点的生长表现是4个试点中最好的,4个树种的平均单株材积为0.015 57 m^3。5年生时,生长表现最好的是大叶斑皮桉,平均单株材积0.042 16 m3;德庆试点的生长表现是3个试点中最好的,4个树种的平均单株材积为0.068 89 m^3。

The growth performance of 4 Corymbia species in Guangdong Province

Study on growth performance of 4 Corymbia species introduced from eastern Australia was con- ducted. Height growth, diameter at breast height （DBH） and single-tree volume have most significant differences among sites, species and site×species. The results of 3 years＇ trial were summarized as follows： C. variegata was the best species, its mean single volume was 0. 007 191 m^3. The growth performance of Deqing site was best. The results of 5 years＇ trial were summarized as follows： C. henryi was the best species, its mean single volume was 0. 042 16 m^3. The growth performance of Deqing site was best.
