杉木萌芽林林冠下营造木荷后土壤肥力状况的研究

Studies on the Soil Fertllity after Planting Schima superba under the Canopies of Cunninghamia lanceolata Coppice Forest

通过对杉木萌芽林林冠下营造木荷后形成的混交林土壤肥力变化的测定与分析表明：与杉木纯林相比，混交林凋落物量较多，且易于分解，灰分养分较为丰富，土壤有机质含量较高，土壤结构稳定性好，土体疏松多孔，养分贮量大，供肥能力较强，这表明杉木萌芽林经改造形成稳定的混交林后土壤肥力状况有较大程度的改善。

The results indicate that as compared with the pure forest of Cunninghamia lanceolata，the mixed.forest forming after Schime superba was planted under the canopies of C. lanceolata coppice forest possessesthe following merits：its ash and nutrient are richer，its soil organic material content is higher，its soil struc-ture stability is better a1id its capacity of providing fertilizers is stronger.
