| 摘 要： | 利用Pallo法，将土壤腐殖质分为FAf、HAs、HAp、FAs、FAp和HM共6个组分（HAs和FAs为松结合态腐殖质工，HAp和FAp为稳结合态腐殖质Ⅱ，HM为紧结合态腐殖质Ⅲ），研究了长期定位施肥（ck、M2、M4、NPK、M2＋NPK和M4＋NPK）对黑土腐殖质各组分的影响。结果表明：腐殖质各组分的碳量由高到低的顺序为HAp〉HAs〉FAp〉FM〉FAs。长期施肥有利于SOC、FAf碳量的积累和松、稳、紧结合态腐殖质碳量的增加，有利于土壤腐殖质Ⅰ／Ⅱ值的提高和Ⅰ／Ⅲ值的降低。各施肥处理中松、稳、紧结合态腐殖质积累效果相比，高量有机肥长期配施化肥的最好，而单施化肥的效果最差。长期单施化肥使土壤松结合态和稳结合态腐殖质的PQ值增加，腐殖化作用增强。 |

| Abstract: | Humus plays an important role in soil fertilizer and it supports necessary nutrition that plants live on.The humus was divided into 6 fractions by Pallo method including FAf,HAs,HAp,FAs,FAp and HM(HAs and FAs are loosely united humus.HAp and FAp are steadily united humus.HM is tightly united humus.),and the effects of long-term located fertilization(ck,M2,M4,NPK,M2+NPK and M4+NPK) on humus fractions were studied in this paper.Results showed that the carbon content sequence of humus fractions was HAp>HAs> FA... |
