摘　　要：[目的]为实现生土快速改良。[方法]通过定点田间试验,探索了不同培肥模式对土壤物理、化学与生物学性状的影响。[结果]绿肥处理、绿肥结合化肥处理、绿肥结合有机肥处理3年后土壤水稳性团聚体含量从15.13%分别提高到17.29%、16.29%和19.16%,土壤有机质含量从6.28%分别提高到7.05%、7.28%和7.48%,土壤呼吸强度从10.43 mg/(kg·d)分别提高到16.35、17.02和21.42mg/(kg·d)。[结论]从长效机制来看,对于黄土状母质发育的待复垦生土,采取绿肥结合有机肥处理措施的土壤培肥效果最优。[ Objective ] The research aimed to improve immature soil rapidly. [ Method] Different models for the improvement of soil fertility by site-directed field experiments were studied, including physical, chemical and biological impacts of immature soil. [ Result ] Three years after green manure treatment, the content of water stable aggregates of green manure combined with chemical fertilizer treatment, manure combined with organic fertilizer treatment significantly increased to 17.29%, 16.29% and 19.16% from 15.13%, the content of soil organie matter signif- icantly increased to 7.05%, 7.28% and 7.48% from 6.28%, soil respiration intensity significant increased to 16.35 , 17.02 and 21.42 mg/（ kg · d） from 10.43 mg,/（ kg · d） . [ Conclusion] Green manure combined with organic fertilizer treatment showed the best effect on the improvement of soil fertility in the long run.
