闽南山地卷荚相思家系造林试验

Afforestation Experiment on Acacia cincinnata Families in the Mountains of Southern Fujian

为了筛选出适合闽南北部山地栽培的优良卷荚相思家系,华安金山国有林场优选9个卷荚相思家系进行造林试验,对不同家系林分的生长性状、适应性和抗逆性进行对比分析。结果表明,参试家系均表现出较强的抗风性和抗寒性,可以适应闽南北部区域环境。但不同家系的树高、胸径、材积和枝下高差异显著或极显著,其中Z5和Z7家系的生长表现优于其他家系,其树高、胸径、材积、枝下高比群体均值分别提高10.80%~11.59%、11.85%~15.05%、35.62%~41.78%和10.98%~13.41%。Z5和Z7家系初步评价为优良家系,可作为卷荚相思在闽南北部推广造林的推荐材料。

In order to select superior families of Acacia cincinnata which are suitable for northern mountains cultivation in southern Fujian,9 families of Acacia cincinnata were optimized for afforestation experiment in Hua′an Jinshan State-owned Forest Farm,the differences of 9 families in growth characters,adaptability and stress resistance were analyzed.The results showed that Acacia cincinnata′families showed strong wind resistance and cold resistance,which could adapt to the environment in northern area of southern Fujian.However,the tree height,DBH,volume and under-branch height of different families showed significant or extremly significant differences,and the growth performance of Z5 and Z7 family were superior to other families,the tree height,DBH,volume and under-branch height increased respectively by 10.80%-11.59%,11.85%-15.05%,35.62%-41.78%and 10.98%-13.41%than group average value.Z5 and Z7 family preliminary evaluate for fine families,which can be used as recommend materials for Acacia cincinnata afforestation in northern area of southern Fujian.
