The increased amount of non--exchangeable NH4^＋-N during the incubation indicated as the following tendency, namely, Eum-Orthic Anthrosols 〉 Los - Orthic Entisols 〉 Hap-Ustic Isohumisols 〉 Ust-Sandiic Entisols. Organic material influenced significantly the increased amount of non-exchangeable NH4^＋-N （P was 0.0002, 0.0004 and 0.0003 when incubated at 20 d, 50 d and 60 d, respectively）. NH4^＋-N increased remarkably when Stlpa bungeana and Medicago sativa were added compared with no addition. The contents of non-exchangeable NH4^＋-N increased significantly when added （NH4）2SO4 compared without addition at 20 d, 40 d and 60d of incubation and P was 0.0037, 0.0033 and 0.0027, respectively. It was the result that the NH4^＋-N from （NH4）2 SO4 was fixed within the soil. The increased amount of non-exchangeable NH4^＋-N increased significantly for different soils, on which different vegetation types grew before the collection of soil samples, when incubated at 20 d （P=0.0434）, but not significantly at 40 d and 60d （P=0.7378 and 0.5375）. The increased amount of non-exchangeable NH4^＋-N in the soil, on which crop straw and nitrogen fertilizer had been incorporated for a long-term period, was larger than that of no addition, but it was not significantly different among these two fertilization models. Soil clay, total N and organic matter were positively correlated remarkably with the contents of non-exchangeable NH4^＋-N, the increased amount of non-exchangeable NH4^＋-N had no correlation with soil clay, whereas it had significantly positive correlation with total N and organic matter.

培养期间非交换性NH4^＋-N的增加量均表现为以土垫旱耕人为土最大，其次是黄土正常新成土，简育干润均腐土和干湿砂质新成土较小；添加有机物料极显著影响培养期间的非交换性NH4^＋-N增加量（培养20d、40d和60d时P分别为0.0002，0.004和0.0003），表现为紫花苜蓿和长芒草土壤非交换性NH4^＋-N的增加量均极显著高于不添加有机物料的对照土壤；在培养20d、40d和60d时，加（NH4）2SO4土样非交换性NH4^＋-N的增加量显著大于不加（NH4）2SO4土样（户分别为0.0037，0.0033和0.0027），这是土壤对（NH4）2SO4中NH4^＋-N固定的必然结果；不同植被类型土壤培养20d时的非交换性NH4^＋-N增加量差异显著（P=0.0434），培养40d和60d时差异不显著（p分别为0.7378和0.5375）；长期秸秆和氮肥配施土壤非交换性NH4^＋-N增加量大于不施肥对照土壤，但差异不显著土壤黏粒、全氮和有机质与培养0d、20d、40d和60d时土壤的非交换性NH4^＋-N含量均呈极显著正相关；而非交换性NH4^＋-N的增加量与粘粒无相关性，但与全氛和有机质呈显著正相关。
