全椒县耕地土壤中磷的地球化学特征
|
摘要
[目的]研究全椒县土壤磷含量及营养丰缺情况,为土壤改良等提供理论依据。[方法]采集1 170个样品,测试了样品的pH、全磷含量以及速效磷含量。[结果]研究区酸性土壤占66.07%,浅层土壤中全磷含量为86.7~1 510.0 mg/kg,全磷等级四等和五等的占92.56%,土壤中磷活化系数小于2%的样品占83.33%。[结论]pH、有机质是影响全磷转化的影响因素。
[Objective]To understand phosphorus content and condition of abundance and deficiency of phosphorus in the cultivated soil in Quanjiao County,and provides important evidence for the soil improvement in the research area. [Method]1 170 samples were collected,and the pH value,total phosphorus content and rapid phosphorus content was tested. [Result]Acid soil accounted for 66.07%,and the content of total phosphorus ranged from 186.7 mg/kg to 1 510.0 mg/kg,and level four and level five of the total phosphorus accounted for 92.56%,the phosphorus activation coefficient less than 2% accounted for 83.33%. [Conclusion] pH value and the organic matter content have important effect on the transformation of the total phosphorus.
