摘　　要：对福州市起源于红壤和冲积物母质上的几种菜园土的土壤及其微团聚体性质测定结果表明 :经长期培育的高度熟化菜园土 ,其土壤养分贮量和有效养分含量均大幅度提高 ;腐殖质HA/FA、胡敏酸芳构化度和腐殖质氧化稳定性均明显增大 ;不同结合态腐殖质以松、紧结合态为主 ,二者绝对含量均明显增加 .The results indicated that nutrient, HA/FA, the aromaticity of humic acid, K OS , and the contents of loosely and tightly bounded humus in highly mellowing vegetable soils are improved greatly by vegetable growing. The content and activity of micro aggregates increased. This indicated acceleration of organic matter renewing and nutrient cycling.
