摘  要:
采用土壤长期定位试验分析方法,研究了黑土有机物质的变化。结果表明,有机肥处理平均OM超过化肥处理20.7%,差异极显著,单施氮肥Kos最高。胡敏酸以M最高,胡/富比基本均大于1,以休闲地为最高。微团聚体中有机碳、氮MA25

摘  要:
The results from analyzing long -te rm location field experiment in blac k soil show that organic matter conte nt in the soil receiving organic manure disposal(OMD)was 20.7%more than that of chemical f ertilizer disposal(CFD).Kos of single Ndisposal and humic acid of single organic manure were the largest.HA /FA ratio was g enerally more than 1.Organic carbon and organic nitrogen in each microaggregates we re MA1>MA5>MA25,and in different tr eatments,OMD>CFD>Native.Content of humic matter in MA1was markedly higher than other two fractions.Organic carbon and organic nitrogen in G0and G1were in an order:OMD>CFD.However,G2was opposite,e specially,in the treatment of MNPK.It is concluded that organic manure,which is capable of increasing amounts of soil organic substance and ameliorate i ts quality,was propitious to organi c nutrient conservation in G1and release in G2,and MA1was important pool of organic matter.
