钙质紫色土区不同利用方式对土壤养分的影响

Effects of Different Land Use Types on Soil Nutrients in Calcareous Purple Soil Regions

  • 摘要: 以四川盆地丘陵区梓潼县为例,通过实地调查、土壤采样分析和数理统计结合的方法,对4种典型的紫色土利用方式(水田、旱地、林地、草地)的土壤养分状况进行了分析。研究结果表明:土地利用方式对土壤的有机质、全氮、全钾、全磷、碱解氮、速效钾和速效磷的含量均有显著的影响;在4种土地利用方式中,土壤有机质和土壤氮素含量由高到低的顺序为:水田 > 林地 > 旱地 > 荒草地;土壤磷含量为:旱地 > 林地 > 水田 > 荒草地;土壤全钾和速效钾含量由高到低的顺序为:水田 > 旱地 > 林地 > 荒草地。

     

    Abstract: Taking Zitong County of Sichuan Province for an example, researches were conducted on effects of different land use types on soil nutrients by use of the method of soil sampling and laboratory analysis. The result indicated that the different land use types had significant impacts on soil nutrients. The content of soil organic matter and soil N would decline in sequence from paddy land, forest land, dry land to grassland. The content of soil total P and available P would decline in sequence from dry land, forest land, paddy land to grassland. The content of soil total K would and available K decline in sequence from paddy land, dry land, forest land to grassland.
