摘要
为研究滇东南毛花酸竹林土壤养分特征,在天然林和人工纯林以及有人工经营措施的天然林中分别设置土壤样地,分析其土壤p H值、全N、速效P、速效K、有机质含量等指标。结果表明,不同类型毛花酸竹林p H值较为稳定;天然竹林中林缘处养分含量更高;人工经营措施对天然竹林立地生产力有提升效果,尤其是施肥对增加土壤有机质、全N、速效P、速效K含量较为明显。研究结果可为云南毛花酸竹林的经营管理提供参考。
In order to study on soil nutrient of Acidosasa hirtiflora stands in southeastern Yunnan, samples were set in nature stands , artificial operation stands , and nature stands with some management, the result showed that soil pH value was stable in different samples. The edge of forest had higher contents of nutrient in nature stand. Artificial operation could promoted forest productivities, fertilization could increased total nitrogen, available phosphorous, available potassium and organic matter obviously.
