林文锋, 黄林青
福建省南安五台山国有林场
摘要:
在五台山林场引种卷荚相思3年试验结果表明,卷荚相思能适应林场的立地和气候条件,生长快且好,胸径和树高年生长量分别为3 cm,2.5 m;不同坡向,坡位,立地条件下卷荚相思生长差异显著,试验结果表明,五台山地区比较适合种植卷荚相思,尽管在冬季有严重的霜冻,但试验林未出现严重寒害。

The Growth Performance of Acacia cincinata in Wutaishan Forestry State Farm of Fujian Province
Lin Wenfeng, Huang Linqing
Fujian Province Nan'an Wutaishan Forestry State Farm
Abstract:
Acacia cincinata is a tropics and subtropics lowly nitrogen fixation tree species. When it has been introduced to a variety areas in china espeically in the northern area which the north latitude over 25°, there is cold injury happen now and then. The experiment indicated that, Acacia cincinata adapts the locality in the Wutaishan forest farm and the climatic conditions, the growth is comparatively quick and better, the diameter and the high annual growth respectively reaches about 3 cm, 2.5 m; Although has cold injury, but is slighter, only the terminal bud and the tender branches and leaves suffered injury. Different field, the different slope direction and slope location have very tremendous influence to the young tree growth, therefore the growth difference is big. All experiments demonstrated that the field is good, the young tree grows quick and good, otherwise grows slowly; The influence of slope position to the young tree growth basically is the downhill > center slope > uphill (small terrain influence is an exception); The slope direction also has the very tremendous influence to tree's growth, the northeast slope grows well, northwest slope growth is ordinary, north the slope grows bad.
Key words:  Acacia cincinata, compatibility, slope direction, field, slope position
