滇中不同植物群落土壤团聚体组成及养分特征OA北大核心CSCDCSTPCD
Characteristics and Distribution of Nutrients in Soil Aggregates under Different Plant Communities in Central Yunnan
采用野外调查和室内分析相结合的方法,对滇中富源县境内华山松-栓皮栎混交林、旱冬瓜林、杨梅灌丛、云南松林、撂荒地5类群落类型的团聚体粒径组成及养分特征进行研究。结果表明,团聚体含量随着粒径（〉5 mm,5～3 mm,3～1 mm,1～0.5 mm,0.5～0.25 mm,〈0.25 mm）的增大及土层（0-10 cm,10-20 cm）的加深而逐渐增多;团聚体的养分含量也呈现一定差异,有机碳、全氮、全钾和水解氮含量随粒径的减小而增多;速效钾含量则随…查看全部>>
By the field investigation and laboratory analysis methods,through research the characteristics and distribution of nutrients in soil aggregates of Pinus armandii-Quercus variabilis mixed forest,Alnus nepalensis forest,Myrica rubra shrubs,Pinus Yunnanensis forest and abandoned land in central Yunnan.It resulted that the distribution of aggregate increased with the particle sizes 〉5 mm,5～3 mm,3～1 mm,1～0.5 mm,0.5～0.25 mm,〈0.25 mm and layers 0-10 cm,10-20cm of …查看全部>>
