摘要 对鼠茅草覆盖条件下的油茶林地土壤理化性质及土壤酶活性等指标进行测定与分析。结果表明,覆盖鼠茅草的油茶林地土壤电导率、pH值、土壤含水率与无覆草林地(对照)间均存在显著差异,且其土壤全碳(TC)、全氮(TN)和钠元素含量及碳氮比均高于对照,土壤脲酶活性和酸性磷酸酶活性也均显著高于无覆草的油茶林地,说明覆盖鼠茅草不仅能提高油茶林地土壤的酸碱性、电导率、含水量和酶活性,还在一定程度上提高了油茶林地土壤肥力,对油茶林地土壤改良和可持续生产具有积极的作用。 The soil physical and chemical properties and enzyme activities were measured and analyzed for Camellia oleifera woodland mulched with Vulpia myuros.Significant difference in soil was noted between mulched area and non mulched area in electrical conductivity,pH value and water content.Compared with non mulched soil(control),the soil from Camellia oleifera forest mulched with Vulpia myuros exhibited a higher content of total carbon,total nitrogen and sodium and a greater carbon to nitrogen ratio.The urease activity and acid phosphatase activity were significantly stronger in mulched C.oleifera forest soil than in non mulched soil.Mulching with V.myuros not only improved the pH value,electrical conductivity,water content and enzyme activity of Camellia oleifera forest soil,but also improved the soil fertility to a certain extent.In summary,mulching with V.myuros has a positive effect on the soil improvement and sustainable production of C.oleifera forest.
