山东昌乐表层土壤农业地球化学评价探讨

Discussion on the Agricultural Geochemical Evaluation of Surface Soil in Changle, Shandong Province

对昌乐县进行土壤地球化学调查,包括表层土壤地球化学调查和深层土壤地球化学调查,主要研究表层和深层土壤中52种元素、有机质、pH值含量及其空间分布特征.重点是进行土壤营养元素的全量的丰缺性评价,结合各区域自然条件与环境质量状况,进行农业地球区划.总体来看,昌乐县整体呈现南酸北碱的分布特征,在实际农业生产中,需综合考虑土壤酸碱度.对于局部强酸性土壤,有必要利用农业科技手段改善土壤质量.表层土壤中营养元素的含量丰缺评价,为农业合理施肥提供技术支撑,有利于当地农业生产.

Thisstudy is just for geochemicalsoilsurveying in country of ChangLe, includingsurfacesoil geochemicalsurvey and deepsoil geochemicalsurvey, themain researchsoil layers 52 elements, organicmatter, pH value of the content and itsspatial distribution. Focus is on full amount ofsoil nutrients abundance evaluation, in conjunction with the regional natural conditions and environmental quality conditions, agricultural regional earth planning. Overall, the wholeshow distribution of ChangLe County acid in north and alkaline insouth, in actual agricultural production, we need to consider thesoil pH. For topicalstrongly acidicsoil, it is necessary to take advantage of agricuituralscientific and technologicalmeans to improvesoil quality. Abundance evaluation of content nutrients insurfacesoil, which is providing technicalsupport for agriculture rational fertilization, would conducive to of local agricultural production.
