摘　　要：黑荆树(Acacia mearnsii)作为短周期工业人工林进行集约经营,施肥是一项重要的增产措施。南方各省一般用于营造黑剂树的山地土壤较瘠薄,加上黑剂树生长快、伐期短,吸收土壤养分多,而只有少数枝叶能形成矿质养分回到土壤。南非试验表明:施一定量过磷酸钙的黑荆树人工林,10年轮伐时,每公顷可增加鲜树皮6t、木材30t。本试验主要探讨N、Fertilization results for four years indicate that single fertilization for three fertilizer elements, N, P, K, and their combining fertilization significantly effect on height, diameter, volume and bark production, tannin yield and thickness of bark, and economic benefit compared to control experiments. Different combinations among the three elements show significant differences. Phosphorous fertilizer is of first importance to increase the production for A. mearnsii. This paper mainly describes and reviews basical information for trial sites, methods and results.
