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 .这些决定了菜园土具有很强的供肥能力和良好的土壤结构
The results of soil and its microaggregates on the soil and its microaggregates in Fuzhou, which originated from the red soil and the alluvial parent material, show that the soil nutrient storage and the effective nutrient content in the highly matured garden soil cultivated over a long period of time are greatly increased ; Humic HA / FA, humic acid aromatization and humus oxidation stability were significantly increased; different bound humus was mainly loose and tightly bound, the absolute content of both increased significantly. These determine the garden soil has Strong supply of fertilizer and good soil structure
