山东省沂源县耕层土壤营养元素有效态含量及其影响因素研究
Study on Available Content of Nutrient Elements in Surface Soil and Influencing Factors in Yiyuan County, Shandong Province
摘要
Abstract
The investigation results of nutrient elements in surface soil of Yiyuan County showed that the available contents of N , P, K, Ca, Mg, S, Cu, Zn, Fe, Mn and Si were abundant , while those of B and Mo were lack .The statistical results indicated that significant or very significant positive correlations were found between pH value and the available contents of K , Ca, S, B, Mo and Si, and significant or very significant negative correlations were found between pH value and the available contents of N , P, Fe and Mn.This find-ing suggested that the available contents of elements should not be completely controlled by pH value .Signifi-cant positive correlations were found between organic matter and the available contents of N , P, K, Ca, Zn, B and Si, which suggested that organic matter should be the important control factor promoting element activation .关键词
