三明格氏栲自然保护区土壤条件和肥力状况的研究

研究表明 ,天然格氏栲林下土壤的质地大都为重壤土至轻粘土 ,其土壤的全氮、有机质及速效养分含量都明显高于其他林分的土壤。天然格氏栲林下土壤进入红壤土壤成土过程的最高阶段 ,形成具有较高肥力的土壤

Studies on the Soil Conditions and Fertility Status of Sanming Natural Reserves of Castanopsis kawakamii

The studies show that the textures of soils under natural Castanopsis kawakamii forests are mostly heavy loams or light clays,the total N,organic matter and rapidly available nutrient contents of soils are all evidently higher than those of soils under other stands The soils under natural C.kawakamii forests are into the peak period of red soil formation course ,the soils with relatively high fertility form.
