摘　　要：利用微区 (1m2 ) 16年定位试验研究了不同施肥措施在相同气候条件、轮作制度及相同管理措施下对山东省三大主要土类———棕壤、潮土、褐土腐殖质组成的影响。结果表明长期施用化肥可使三种土壤腐殖质各组分积累 ;氮钾肥提高了土壤腐殖酸碳与有机碳的比值 ,降低腐殖酸活性 (提高HA/FA比值 ) ;与单施化肥比较 ,化肥配施有机肥大幅度增加了土壤胡敏素和腐殖酸数量 。This paper studied fertilizing influence on humus composition in main three soils at Shandong province by sixteen years fixed position trial. The result showed that long-term fertilization promoted accumulation of humus composition; Nitrogen and potassium increased ratio of humus acid carbon and organic carbon,decreased the activity of humus acid in three soils. Compared with Chemical fertilizer, Chemical fertilizer plus organic- fertilizer largely raised humin and humus acid, lowered ratio of humin and humus acid in soil.
