闽南山地卷荚相思家系造林试验

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。

Afforestation Experiment on Acacia cincinnata Families in Southern Fujian

This paper aimed to select superior families of Acacia cincinnata. Forestation test of different families was conducted in. Growth indicators, adaptability and adversity resistance of families was analysed. The results showed that, all of the families had strong wind resistance and cold resistance and adapted to the environment of southern Fujian. The height, DBH, volume and under-branch height of different families had significant difference or extremely significant difference. Z5 family and Z7 family performed more excellently than other families. Height , DBH, volume and under-branch height of Z5 family and Z7 family were more than the overall average values by 10.85%-11.59%, 11.85%-15.05%, 35.62%-41.78% and 10.98%-13.41%, respectively. In summary, Z5 family and Z7 family was the optimal families, and should be recommended in production practice.
