摘要
本文通过对山西五台山区七种主要垂直带土壤多糖含量的分析,结果表明:五台山土壤中多糖含量随海拔降低,土层加深而逐渐减少,并且土壤多糖含量与土壤有机质,全氮、全磷、代换量、土壤脲酶活性里显著正相关,因此土壤多糖也可作为评价土壤肥力的重要指标之一.
In the Paper, the contents of polysaccharide in the siol vertical zone of Wutai Mountains were studied. The results showed, the contents of polysaccaride tended decreased with both drop of elevation and both of siol profile and it was found. That thd content of polysaccharide had obvious positive correlations with O. M. TOTAL-N, TOTAL-P CEC and activity of urease. The content of polysaccharide can be regarded as one of the importand indexes of evaluating siol fertility.
