Nitrification and denitrification potential were studied by incubation experiments using soil samples taken from five main soil types in the North China Plain. Results show that nitrification rates were 7.9%, 20.8%, 46.4%, 22.5% and 20.3% for shajiang black soil, fluvo-aquic soil, drab soil, dune soil and salt-affected soil, respectively, after incubation of 28 hours. It also was discovered that it increased to 18.7% in sandy black soil, and 98.3%— 100% in the rest 4 soils after incubation...

Results show that nitrification rates were 7.9%, 20.8%, 46.4%, 22.5% and 20.3% for shajiang black soil, fluvo-aquic soil, drab soil, dune soil and salt-affected soil, respectively, after incubation of 28 hours. It also was discovered that it increased to 18.7% in sandy black soil, and 98.3%— 100% in the rest 4 soils after incubation of 100 hours. N2O emitted from the above 5 soils was found to be: 0.04, 0.27, 0.24, 0.41and 0.45 μg N·g-1soil after incubation of 268 hours. The corresponding loss by denitrification was 0.6, 0.3, 0.08, 0.02 and 0.05 μg N·g-1 soil after incubation of 650 hours. The results indicated that shajiang black soil is characterized by relatively lower nitrification potential and higher denitrification potential than the rest 4 soils. The potential of nitrification and denitrification was related to soil texture and/or soil pH, but not clearly related to the numbers of nitrifying and denitrifying bacteria.

取用华北平原5种主要土壤进行实验室培养试验,研究不同类型土壤间硝化反硝化活性的差异。结果表明,培养28h后砂姜黑土、潮土、褐土、盐渍土和风沙土的硝化率分别为7.9%、20.8%、46.4%、22.5%和20.3%;148h后砂姜黑土的硝化率为18.7%,其它4种土壤达98.4%—100%,基本硝化完全;培养268h释放的N2O总量分别为0.04、0.27、0.24、0.41和0.45μgN·g-1土。培养650h的反硝化损失量分别为0.6、0.3、0.08、0.02和0.05μgN·g-1土。可见,不同的土壤中砂姜黑土的硝化作用活性较弱,而反硝化活性较强;潮土、褐土、盐渍土和风沙土的硝化作用活性较强,而反硝化活性相对较弱。土壤的硝化及反硝化作用与土壤质地和pH有关,与硝化和反硝化菌数量无明显相关性。

The soil cultivation method was used to study the effect of 9 kinds of PBP(polyphenols of banana pseudostem)and two dosages of DCD (dicyandiamide) on the transformation of urea-N in soil.The results indicated that PBP 3-9 and DCD could reduce the nitrification potential of soil significantly and increase the content of NH4+-N in the soil, and the nitrification potential of PBP 3-9 was significantly lower than that of DCD. The results of nitrification intension test indicated that PBP 6 and PBP 9 could inhibit urea hydrolysis for 2 days, DCD and the other PBP could not.PBP 4-9 and the DCD could keep higher content of NH4+-N in the soil for over 49 days. Each kind of PBP could reduce nitrification intension and the content of NO3--N in the soil treated with PBP2-9 was significantly lower than that with DCD.

The potential of nitrification and denitrification of sediment and the density of ammonium-oxidizing bacteria and nitrite-oxidizing bacteria in sediment in water quality purifying system with hydroponic bio-filter method (HBFM) were measured. The variation of nitrification and denitrification potential of the sediment along the stream way was quantitatively studied. The results show that among the sediments from front, middle and retral part of the stream way, the sediment from middle part reached a maximum nitrification potential of 4.76×10 -6 g/(g·h), while the sediment from front part reached a maximum denitrification potential of 8.1×10 -7 g/(g·h). The distribution of nitrification potential accords with the ammonium-oxidizing bacteria density. The key for improving nitrogen removal efficiency of HBFM system consists in changing nitrification & denitrification region distributing and accordingly enhances denitrification process.
