This study represents the first attempt to develop growth functions for Eucalyptus gunnii grown in the UK. Functions relating height and age, height and DBH, cumulative volume and age and mean annual increment and age were developed using historic data. These indicated that stands in the UK achieved an average growth rate of 16 m3 ha−1 y−1 or approximately 8 Mg ha−1 y−1 of dry stem biomass at an age of twenty years. There is evidence that yields can be considerably higher where intensive silviculture, such as use of plastic mulches and nutrient inputs has been practised, such as at Daneshill in Nottinghamshire, where trees attained a height of 10.6 m in five and a half years. However, potential yields are often compromised by high mortality and a priority should be to identify areas in the UK where E. gunnii can be grown with low risk and also to choose well adapted genetic material.

英国桉树的初步生长功能

这项研究代表了为英国生长的桉树开发生长功能的首次尝试。使用历史数据开发了与身高和年龄,身高和DBH,累积体积和年龄以及平均年增量和年龄有关的功能。这些表明英国林分的平均增长率为16 m 3  ha -1  y -1或大约8 Mg ha -1  y -120岁时的干茎生物量。有证据表明,在进行密集的造林(例如使用塑料覆盖物和营养物)的地方,例如在诺丁汉郡的Daneshill,树木在五年半内达到10.6 m的高度时,单产会更高。但是,潜在的产量往往会因高死亡率而受到损害,因此应优先考虑在英国确定可以以低风险种植古埃希氏菌的地区,并选择适应性强的遗传材料。
