摘要: 借助15年的定位观测资料,系统地研究了长期施肥对土壤微生物含量、腐殖质组分、作物产量和土壤供肥能力的影响。结果表明,长期施用化肥和有机肥或两者配施,耕层土壤微生物和胡敏酸、富里酸、胡敏素含量增加,HA/FA比值增大;与腐殖质组成成分最为密切的农化性状是全氮和碱解氮,其次是速效磷;长期不施肥、单施氮肥或有机肥,因养分单一,供肥不足,作物产量逐年下降,抗逆力差。

关键词: 长期施肥, 微生物, 腐殖质组分, 产量

Abstract: By means of 15 year long term yield experiment,the effects of long term tertilizer application on soil microorganism content,humus compositions,crop yield and soil fertility were studied systematically.The results showed that long term application of chemical and organic fertilizes could increase the contents of microorganism,humic acid,fulvic acid and humin in the cultivated soil horizon and the ratio of HA/FA.It was found that chemical properties closely related to humus compositions were the total and arailable nitrogen,and fast phosphorus. No application of fertilizers or single application of N fertilizers or manure during long periods would result in the decrease of crop yield and low resistance to stress.

Key words: Long term fertilization, Microorgnism, Humus compositions, Yield
