摘    要:对常宁地区不同抚育措施油茶林的土壤养分、微生物及酶活性进行了测定和分析。结果表明:各林分间土壤养分、微生物数量和酶活性存在较大差异。同一林分土壤养分、微生物数量和酶活性随取样深度的增加逐渐降低。锄抚林地在土壤养分、微生物总数和酶活性方面明显高于未抚育和刀抚林分。相关分析表明,这3种林分的土壤养分(有机质、全氮、碱解氮和速效磷)与微生物数量及酶活性之间存在相关关系;细菌数量和脲酶活性与土壤有机质、全氮、碱解氮和速效磷等主要养分指标呈显著或极显著正相关;过氧化氢酶和蔗糖酶活性与土壤养分指标间相关性不强。

关 键 词:油茶  土壤养分  微生物  酶活性

Abstract:The soil nutrient,microorganism and enzyme activity were studied and analyzed in Oiltea camelli plantations in Changning area.The results showed the differences of microorganism quantity among different types of soil was significant,so were the enzyme activity and soil nutrient.However,distribution of the nutrients and enzymatic activities in the soil profile was same.With the depth added,the soil nutrient,microbe populations and enzyme activities declined continually.The soil nutrient,microorganism and enzyme activity in the farming land were obviously higher than those in other types of soil.Moreover,it was revealed that the soil nutrient was closely related to the change of biological properties and among themselves.The correlation among soil microorganism quantity,enzyme activity and soil nutrient content is significant,it can be used as evaluation index of soil fertility.
Keywords:Camellia oleifera  soil nutrient  microorganism  enzyme activity
