Abstract Ammonia (NH3) volatilization was a vital process of the nitrogen cycle in agricultural ecosystems and closely related to the atmospheric environment quality. To investigate the tillage practice and N fertilization impact on the soil labile C, N pools and their effects on ammonia volatilization from wheat fields. A two-year consecutive field experiment was conducted at 2017 and 2018. The split-plot design of three tillage systems (conventional tillage (CT), film mulching (FM), straw residue incorporated into soil (SM)) and three nitrogen rates (the control rate (N0), 144 kg N ha−1 (N144), 180 kg N ha−1 (N180)) was applied. The results showed that the NH3 volatilization occurred during 40 days and peaked in 2 weeks post N fertilization. FM could significantly cut down ammonia volatilization peaks, cumulative NH3 loss and ammonia loss rate during both seasons (p

地膜覆盖、残留物滞留和施氮肥通过土壤不稳定氮和碳库影响氨挥发

摘要 氨（NH3）挥发是农业生态系统氮循环的重要过程，与大气环境质量密切相关。调查耕作和施氮对土壤不稳定碳、氮库的影响及其对麦田氨挥发的影响。2017年和2018年进行了连续两年的田间试验。 三种耕作系统（常规耕作（CT）、地膜覆盖（FM）、秸秆还田（SM））和三种施氮量（应用控制率 (N0)、144 kg N ha-1 (N144)、180 kg N ha-1 (N180))。结果表明，NH3 挥发发生在 40 天期间，并在施氮后 2 周达到峰值。FM 可以显着降低氨挥发峰，
