| 摘 要： | 为探究柚木人工林对土壤质量的影响程度,对闽南山地八年生柚木人工林的土壤理化性状、微生物数量与酶活性进行测定分析,结果表明：在有施肥的情况下,柚木地土壤除磷素含量有所降低外,N、K、Ca、Mg等元素养分量均略有提高,土壤容重、孔隙等物理性状有所改善,土壤细菌、放线菌、真菌的数量以及脲酶等主要酶活性均有不同程度的提高。说明在施肥、抚育等合理经营下,种植柚木不但土壤质量不会恶化,相反会有所改善。

| Abstract: | In order to explore the influence of teak plantation on soil quality,the soil physical and chemical properties,microbial quantity and enzyme activity of 8a teak plantation in south Fujian mountain were measured and analyzed.The results were showed that in the case of fertilization,P in soil decreased slightly,whereas N,K,Ca,Mg and other elements had a slight increase;soil bulk density,porosity and other physical properties improved;soil bacteria,actinomycetes,the number of fungi,as well as key enzymes(urease)activity increased in varying degrees.It was concluded that basing on the fertilization,reasonable management,soil quality will not deteriorate,but improved by the cultivation of teak. |
