摘要：

研究旨在评价2种土壤改良技术（模块土和配方土）对红花槭行道树生长特征及土壤性质的影响，为城市行道树的科学栽培提供参考。在上海市杞青路使用对照土、模块土和配方土3种土壤种植红花槭，对红花槭的生长特征及土壤性质进行调查分析。结果显示，与对照土相比，配方土显著增加了红花槭的叶面积、叶面积指数、总氮和总磷含量，而模块土仅增加了红花槭的叶面积指数和总氮含量。与对照土相比，模块土和配方土均增加了叶片的超氧化物歧化酶、过氧化物酶和总叶绿素含量。此外，与对照土相比，配方土增加了土壤的多酚氧化酶、β-葡萄糖苷酶、pH、总碳、总氮和总磷含量，而模块土仅增加土壤的多酚氧化酶和pH。综合生长状况、生理特征和土壤性质测定结果，模块土和配方土均对红花槭的生长有一定的促进效果，但配方土表现更好，更适于红花槭行道树的栽植。

Abstract:

The aim of this study was to evaluate the effects of two soil improvement techniques (module soils and formula soils) on the growth characteristics and soil properties of street trees of Acer rubrum, to provide reference for the scientific cultivation of street trees in urban areas. In Qiqing Road, Shanghai, three kinds of soil were used to plant A. rubrum, namely control soils, module soils and formula soils. Then, the growth characteristics and soil properties of A. rubrum were investigated and analyzed. Compared with the control soils, the leaf area, leaf area index, total nitrogen and total phosphorus contents of A. rubrum significantly increased in the formula soils; the leaf area index and total nitrogen contents of A. rubrum significantly increased in the module soils. Compared with the control soils, the module soil and formula soil increased the contents of superoxide dismutase, peroxidase and total chlorophyll in leaves. In addition, compared with the control soil, the soil polyphenol oxidase, β-glucosidase, pH, total carbon, total nitrogen and total phosphorus contents significantly increased in the formula soils, and only the polyphenol oxidase and pH of soil significantly increased in the module soils. According to the growth condition, physiological characteristics and soil properties, both the module soils and formula soils had a certain effect on the growth of A. rubrum, but the formula soils had a better performance, which may be more suitable for the planting of A. rubrum.
