摘 要: | 山东省沂源县耕层土壤营养元素调查结果表明:沂源县耕层土壤中有效态N、P、K、Ca、Mg、S、Cu、Zn、Fe、Mn、Si含量丰富,有效态B与有效态Mo含量缺乏。统计分析表明:K、Ca、S、B、Mo、Si元素的有效态含量与土壤pH值之间呈显著或极显著正相关,N、P、Fe、Mn元素有效态含量与土壤pH值之间呈显著或极显著负相关,说明土壤pH值并不是影响元素有效态含量的完全控制因素;土壤有机质含量与N、P、K、Ca、Zn、B、Si元素有效态含量之间呈显著或极显著正相关,说明土壤有机质含量是促进元素活化的重要控制因素。

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 . |
