摘要

通过对延安市北沟小流域典型坝地土壤养分的测定

分析比较了其土壤养分时空分布特征。结果表明

北沟小流域坝地土壤养分分布不平衡

除钾素含量富足外

其它养分含量都很低

特别是有机质和磷含量趋于贫瘠化。有机质、全氮、全磷时空差异都不明显

而速效养分在层次上都表现出鞍形变化趋势且时空差异显著。该项研究可为坝地平衡培肥提供理论依据。

Abstract

Based on comparative analysis on spatial temporal distribution characteristics of soil nutrients of typical dam land in Beigou small watershed of Yan. an City. The results showed that imbalance of soil nutrients was very serious in experimental area

and most soil nut rients were very poor

especially

soil organic matter

total Pand available P

but total K and available K were rich. The insignificant spatial and temporal differences in the soil organic matter

total N and total P were found

yet available nutrients were high-low-high from upper to lower and spatial temporal differences were significant on profile.In the light of these results

the theoretical evidences for balancing fertility of dam land are put forward.
