结合83个县土壤普查,测定6千多个土样,通过微机处理数据,对山东省不同土类微量营养元素含量分析汇总。认为本省土壤以缺硼、锌为主,部分缺锰;在3个地貌区的分布有明显规律,元素间有密切相关;各土类各元素的丰缺也有明显规律,并多呈正偏态分布,应以中位数和平均差表示之;本省土壤工作分类基本适于研究微量元素含量分布和应用微肥的依据;各元素在土壤剖面中含量多随深度而降低;土壤微量元素与成土母质关系密切,pH、碳酸钙也是重要的影响因素。
According to the soil survey of 83 counties, more than 6 000 soil samples were measured. The data of micro-nutrient content in different soil types in Shandong Province were summarized through computer processing. The soil of this province is mainly boron-deficient and zinc-deficient, partly manganese-deficient. There are obvious laws in the distribution of the three landforms and closely related elements. The abundance and shortages of the various soil elements also have obvious regularity , Which should be expressed in terms of median and average difference. The classification of soil work in this province is basically suitable for studying the distribution of trace elements and the basis for using trace fertilizers. The content of each element in the soil profile decreases with the depth, and the contents of soil trace elements and soil formation Parent material is closely related to pH, calcium carbonate is also an important factor.
