摘　　要：土壤肥力是土壤各方面性质的综合反映,是衡量林地生产力高低的重要技术指标。为了指导竹林的合理平衡施肥及管理,提高竹林经营水平,并为促进广西竹产业可持续发展提供科学依据和技术支撑,通过对广西不同栽培区的吊丝竹林土壤中N、P、K等主要养分含量和土壤主要物理性状等指标的测定分析,掌握广西石山区吊丝竹林土壤养分状况及其与吊丝竹生长状况之间的关系。Soil fertility can reflect various aspects of its properties, which is an important technical index for evaluating the forest land productivity. In order to guide rational and balanced fertilization, to enhance the management level of bamboo forest, and to provide scientific basis and technique support for sustainable development of bamboo industry in Guangxi, the contents of main nutrients in soil and main physical characters of soil were analyzed in Dendrocalamus minor forest at different areas in Guangxi. The relationship between the soil nutrient conditions and growth situation of Dendrocalamus minor forest was determined at karst rocky mountainous area in Guangxi.
