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。
