摘  要：
本文以苹果园土壤为研究对象,采用田间试验与室内模拟试验相结合的方法,通过静态箱监测土壤N2O排放、DTM法(田间试验)和硫酸吸收法(室内模拟试验)监测土壤NH3排放,研究了沼液施用方式和土壤含水量(WFPS)对土壤N2O和NH3排放的影响.结果表明:(1)田间不同沼液施用方式下,各处理的氮素气态损失均表现为NH3-N> N2O-N,NH3-N和N2O-N损失量分别占投入氮素的0.54%~36.74%和0.02%~3.39%;与沼液表施处理SA相比,沟施FA或混施IA处理的NH3排放量分别降低了90.38%和96.58%,差异达显著水平(P<0.05),但同时也显著增加了N2O排放,增幅分别为82.40%和58.50%(P<0.05)(.2)室内模拟试验在WFPS40%、WFPS60%条件下IA和SA两种施肥方式对土壤N2O-N和NH3-N排放的规律同田间试验一致,并发现室内模拟试验土壤N2O-N和NH3-N排放均随WFPS的增加而增加.综合田间和室内模拟试验,在土壤WFPS<60%时,沼液混施相较于其他处理可实现果园土壤N2O和NH3的同步减排.

摘  要：
In this study, a combination of field and indoor experiments were conducted to evaluate the impacts of digestate application method and soil water moisture(water filled pore space, WFPS)on the ammonia(NH_3)and nitrous oxide(N_2O)emissions from apple orchard soil. The N_2O emissions were measured using static chamber technique, the field NH_3 emissions were measured using draeger-tube method and the indoor NH_3 emissions were measured using a dynamic chamber technique. Results showed that:(1)the nitrogen losses of the surface(SA),furrow(FA)and incorporation(IA)application treatments were all in an order of NH_3-N > N_2O-N, and the losses of NH_3-N and N_2O-N accounted for 0.54%-36.74% and 0.02%-3.39% of the input N; compared with the SA treatment, FA and IA treatments decreased the NH_3 emissions significantly(P<0.05)by 90.38% and 96.58%, respectively, but at the same time significantly increased the N_2O emissions by 82.40% and 58.50%, respectively(P<0.05).(2)The indoor simulation experiment under 40% and 60% WFPS conditions conformed with the effects of IA and SA application methods on soil N_2O-N and NH_3-N emissions obtained in the field experiment, and also showed that the N_2O-N and NH_3-N emissions increased with WFPS. Combination of the field and indoor experiments demonstrated that the synchronous reduction of N_2O and NH_3 in the orchard soil can be achieved when the digestate is applied using incorporation method under relatively dry soil conditions(WFPS<60%).
