太行山中段典型低山丘陵区土壤营养元素丰缺评价

Evaluation of soil nutrients availability in the typical low mountain areas in the intermediate zone of Taihang Mt.

  • 摘要: 对河北省元氏县前仙乡微地域环境内不同地貌土壤中的营养元素进行了分析评价,查明有效态N含量低、P含量较低,6种微量营养元素亦严重缺乏。其中有90%以上的土壤缺Zn、Mn,80%以上的土壤缺Mo、B,60%以上的土壤缺Cu、Fe。相关统计分析表明,土壤有效态元素含量低与有机质含量低呈显著相关,不同地形影响的土壤类型差异亦是造成土壤肥力不同的重要因素。

     

    Abstract: The availabilities of nitrogen,phosphorus and six trace elements in different topographical soils at Qianxian township of Yuanshi County in Hebei Province were analysed. The results showed that the contents of alkali hydrolysis N and olsen P in topsoil were lower than the average of those in other places of China.The six trace elements were also deficient, about 90% of the land were deficient of Zn and Mn,over 80% deficient of Mo and B,and about 60% deficient of Cu and Fe. The lower availabilities of soil untrients was closely correlated with the lower contents of organic matters.Landforms and soil types were also the factors influencing soil nutrient contents.
