【摘要】 本文通过野外调查采样分析研究了吉林中部不同亚类黑土中硼、钼的含量及垂直分布规律,分析了成土母质、成土过程、成土环境对各微量元素含量及分布的影响。结果表明:红土母质中全钼及有效钼含量均高于黄土母质,而黄土母质中全硼含量较高。全硼在草甸黑土中表现出很强的生物富集特征,其余各剖面表现出较明显的淋溶特征;有效硼表现出生物累积并且从上到下逐渐减小,与有机质之间呈显著正相关。全钼在草甸黑土、德惠典型黑土中有淋溶作用较弱的特点,在长春地区典型黑土中为表层富集,淋溶作用较强的特点;有效钼与全钼变化规律一致,白浆化黑土中有效钼的表层富集和淋溶程度最强。更多还原

【Abstract】 Vertical distribution Pattern of two element content were studied in Different subgroup of Black soils (three subgroup,five profile) in the middle of Jilin province by means of filed work and chemical analysis. The result showed that distri bution of B and Mo was different. Red parent material had high content of total Mo, while loess parent material had high content of total B. Total Mo was enriched in the surface layer. Available Mo showed the same distribution pattern with total Mo.更多还原
