摘要
文章以15年龄中田大山楂林为研究对象,以中田大山楂林附近荒地作为对照,运用湿筛法,对比分析中田大山楂林对土壤团聚体结构的影响。研究结果表明,中田大山楂林样地的土壤团聚体组分质量百分含量大小依次为:大团聚体组分>砂和粘粒组分>微团聚体组分,其中大团聚体组分的质量百分含量占主导地位>70%,说明其土壤结构合理,肥力好;与对照样地相比较,中田大山楂林样地土壤团聚体结构更加稳定,表明中田大山楂林对土壤结构具有明显的优化作用。
This paper uses wet sieving method,and chooses soil of 15-year Zhongtian Large hawthorn plantations as researching materials,and wasteland near Zhongtian large hawthorn plantations as comparison(CK samples),to show the effect of Zhongtian large hawthorn plantations on soil aggregates structure.The results show that the weight percentage content of the soil under Zhongtian large hawthorn plantations is:macroaggregates>silt垣clay fractions>microaggregates,the macroaggregates is the dominant species which is more than 70%,it shows that the healthy soil structure and high fertility;Comparing with the CK samples,the soil aggregate structure of Zhongtian large hawthorn plantations is more stable,it shows that Zhongtian large hawthorn plantations could improve the soil structure.
