武夷山草甸土与黄红壤铵态氮和速效钾对比分析

土壤的肥力状况是有效培育土壤的一项重要指标,研究其成因可以为农业生产合理布局提供参考依据.针对武夷山地区2种不同的土壤类型,通过野外调查取样和室内理化分析方法,对草甸土和黄红壤土壤肥力进行对比研究.分析发现,草甸土铵态氮和速效钾的质量分数明显高于黄红壤.这主要是由于受当地气候、地形、生物以及人类的生产活动所影响.

The comparative analysis of ammonium nitrogen and rapidly available potassium between meadow soil and yellow red soil of Mount Wuyi

The soil fertility is an important indicator to breed the soil effectively.The investigation of its cause of formation will supply the scientific basis with the rational distribution of the agricultural production.Through the methods of field investigation and sampling,and indoor physical and chemical analysis,the research did the comparative investigation to the contents of the ammonium nitrogen and the rapidly available potassium in meadow soil and yellow red soil,two different soil types in Mount Wuyi.Analysis found that the ammonium nitrogen and the rapidly available potassium of meadow soil are visibly higher than those of yellow red soil.This is mainly due to the influnence of the local climate,topography,biology and human production activity.
