英文摘要	Methane oxidation in upland areas plays a critical role in the global methane budget. A three-year field experiment was conducted to investigate the effects of two soil surface treatments including soil covered with black plastic film mulch (BM) and non-mulched treatment (NM), three fertilizer treatments including chemical NPK fertilizer (CF), cattle manure (CM) and their combined application of 50% chemical NPK fertilizer and 50% cattle manure (CF+CM), and three soil wetted proportion levels under drip irrigation including: 35% (P1), 55% (P2) and 75% (P3) on methane oxidation in potato field in the arid area of northwestern China. Results showed that seasonal cumulative methane uptake value was 1.1-4.9 kg hm(-2) in potato upland fields. BM treatment decreased seasonal cumulative methane uptake by 17%-50% compared to NM treatment through increasing average soil temperature by 2.0-2.5 degrees C, increasing average irrigation interval by 0-15% and its barricade effect of gas exchange. CM treatment increased seasonal cumulative methane uptake by 7%-9% and 14%-108% in contrast to CF+CM treatment and CF treatment, respectively, due to the low nitrogen content under CM treatment. Different soil wetted proportions didn't significantly affect methane oxidation, while 35% of soil wetted proportion had the greatest methane oxidation rate. Methane flux was quadratically correlated (p= 0.001) to soil matric potential, and the optimal soil matric potential for methane oxidation was-24 kPa. In summary, this study investigated methane uptake in potato farmland contributing to methane flux budget estimation. Manure applied without mulch had more advantage on methane oxidation, and a soil wetted proportion level of 35% was recommended in this study, for favorable for methane oxidation.
