摘要:
土壤酶是评价土壤环境质量的指示指标。土壤理化性质决定了酶促反应的底物和环境,研究不同连栽代次的巨桉人工林土壤酶活性与土壤理化性质的关系,对于巨桉人工林系统的可持续经营具有重要作用。2016年7月,采用时空互换法,以四川省青神县第一、二和三代巨桉(Eucalyptus grandis)人工林和对照马尾松(Pinus massoniana)林为研究对象,研究了不同连栽代次的巨桉人工林土壤酶活性及其与土壤理化性质的关系。结果表明:与马尾松林相比,一代巨桉林土壤脲酶、多酚氧化酶和过氧化氢酶活性显着增加,蔗糖酶、酸性磷酸酶和过氧化物酶活性无显着变化。但随巨桉连栽代次增加,土壤蔗糖酶、脲酶、酸性磷酸酶、多酚氧化酶、过氧化氢酶和过氧化物酶活性递减。冗余分析表明,土壤容重、pH、有机质、全磷对不同代次的巨桉人工林土壤酶活性影响显着,其中全磷是土壤酶活性最重要的影响因素,能解释酶活性变异的60%。全氮对土壤酶的整体影响不显着,仅能解释土壤酶活性变异的20.5%。但相对重要性分析进一步表明,土壤全氮对脲酶和多酚氧化酶存在显着的影响。研究结果说明巨桉连栽通过影响土壤理化性质进而改变了土壤酶活性。(图3 表6 参35)
Abstract:
Soil enzymes are indicators for evaluating soil environmental quality. Soil physicochemical properties determine the substrate and environment for enzymatic reaction. Studying the relationship between soil enzyme activities and soil physicochemical properties in different successive rotation plantations of E. grandis is very important for sustainable management. In July 2016, we chose the first, second and third rotation plantations of E. grandis and Pinus massoniana forests as the research objects in Qingshen County, Sichuan Province. Soil enzyme activities and their relationship with soil physicochemical properties in different successive rotation plantations of E. grandis were studied using the space-time interchange method. The results showed that compared with the Pinus massoniana forests, the activities of urease, polyphenol oxidase and catalase in the first rotation plantations of E. grandis significantly increased, although the activities of invertase, acid phosphatase and peroxidase did not change significantly. However, with the increasing continuous plantations of Eucalyptus grandis, the activities of soil invertase, urease, acid phosphatase, polyphenol oxidase, catalase and peroxidase decreased. Redundancy analysis showed that soil bulk density, pH, organic matter and total phosphorus significantly affect soil enzyme activities in different successive rotation Plantations of E. grandis. Soil total phosphorus was the most important factor affecting soil enzyme activity, which could explain 60% variation of the soil enzyme activity. Total nitrogen did not have significant effect on the soil enzymes, only 20.5% variation of soil enzymes activity could be explained , although the relative importance analysis further showed that soil total nitrogen had significantly effect on the activities of urease and polyphenol oxidase of E. grandis plantations . The results indicated that soil physicochemical properties could play an important role in continuous cropping processes of E. grandis plantations by regulating soil enzyme activity.
