辽河流域花生产区土壤地球化学特征分析与评价

Soil Geochemical Characteristics Analysis and Evaluation of the Peanut Growing Areas in the Liaohe River Basin

花生丰富的营养价值奠定了其在食品工业中的重要地位。运用区域地球化学调查方法,对辽河流域花生主产区的气候特征和土壤地球化学特征、土壤环境质量,进行了分析评价,认为:1)土壤中富含Si元素和K元素,N、P相对缺乏,微量元素含量低,比较适合花生耐贫瘠的特性,能够满足花生的正常生长。2)土壤中重金属含量低,土壤环境质量优,符合发展绿色花生种植条件。3)土壤孔隙度、持水量、质地适合花生生长的土壤特征,建立了适合花生种植的地球化学模型。4)建议在本文研究的基础上,对整个辽河流域进行土壤环境质量地球化学分类,扩大适合花生种植的区域,为辽河流域花生产业的发展奠定基础。

Peanut holds an important value in food industry for its nutritional value in the Liaohe River Basin survey through the peanut-producing areas.This paper adopts regional geochemical survey methods and analyzes the climate characteristics and the soil geochemical characteristics in the main producing areas in the Liaohe River Basin, appraisals for the environmental quality of soil in the peanut-producing areas ： 1） Elements in the soil is rich in Si and K elements, N, P the relative lack of low content of trace elements, more suitable for peanut barren resistant characteristics, to meet the normal growth of peanuts. 2） Low content of heavy metals in soil, soil environmental quality excellent, in line with the development of green peanut cultivation conditions. 3） Soil porosity and water holding capacity, texture of the soil for the growth characteristics of peanut, determines suitable growth for peanut geochemical model. 4） Proposed on the basis of this article, the Liaohe River Basin for the entire soil geochemical classification of the quality of the environment, the expansion of peanut cultivation in the region suitable for the peanut industry in the Liaohe River Basin lay the foundation for the future development.
