Effect of different fertilization patterns on the N2O emission of Brown soils
This experiment, studying the effect of organic fertilizer, straw application and different long-term rotation fertilization on the emission of N2O is carried out respectively in Laocheng town,Changtu County and the station of long-term fertilization experiment in Shenyang Agriculture University. Results show that different fertilization patterns lead to diversity of flux and dynamic condition of N2O emission.N2O emission increase along with nitrogen fertilization, which provides nitrogen source for denirtification. At the same level of chemical fertilizer, applying both hog manure and straw return could make the emission of N2O increase. Cooperation of bio-fertilizer andabio-fertilizer have the better effect compared with single abiofertilizer or non-fertilization on the emission of N2O.
