黑荆树是一种生长快、用途广的树种。树皮是优质栲胶原料;木材可做矿柱和家具等;根具根瘤,可以固氮,改良土壤。中国在50年代初开始引种,目前主要种植在亚热带的中南部地区,跨经度20°、纬度10°,其垂直分布差为1500m。分布区内气候和土壤差异很大,因此,各种植区只有选择合适的种源进行造林,才能获得理想的产量。 Wattle is a fast-growing, versatile tree species. The bark is a high quality gum material; timber can be used as pillars and furniture; root nodules, nitrogen fixation can improve the soil. China began its introduction in the early 1950s and is now mainly planted in the central and southern subtropics with a longitude of 20 ° and a latitude of 10 °. Its vertical distribution is about 1500 m. Distribution of climate and soil vary greatly, therefore, all kinds of plantations only select the appropriate provenance for afforestation, in order to obtain the desired yield.
