目的由于农学、生态和环境方面的原因，奶牛养殖场废水和有机肥的使用对土壤气体排放的影响是令人关注的。材料和方法2018年11月至2019年5月，我们在江苏竹镇中国进行了一项田间试验，研究了污水和粪便对7个处理(4个重复，28个地块)麦田气体排放的影响：不施肥(对照)；无机肥按常规施肥量200 kg N ha−1(NPK)；100 kg N ha−1无机肥+100(DE1)、150(DE2)和250(DE3)kg N ha−1农场乳品废水，100 kg N ha−1无机肥+100 kg N ha−1农场奶牛粪便(SM1)，150 kg N ha−1无机肥+50 kg N ha−1农场奶牛粪便(SM2)。NH3排放量从1.83(NPK)增加到3.81 kg N ha−1(DE1)和11.4 kg N ha−1(DE3)，这可能是由于土壤NH4+和pH水平升高所致，但与NPK相比对N2O排放没有明显影响。在DE3处理中，随着污水用量的增加，NO排放量较NPK显著增加了33.3%。与不施氮肥相比，有机肥和尿素配施显著减少了N2O和NO的排放，分别减少了25.2-27.6%和8.3-45.8%，而增加了73.8%的NH3排放。结论总体来说，用乳肥替代目前常规施氮量的25%可以显著减少小麦季节的气体排放。
PurposeThe impact of dairy farm effluent and manure applications upon gas emissions from soil is of concern for agronomic, ecological, and environmental reasons. Yet it remains unclear how the optimized manure and effluent additions may affect gas (nitrous oxide (N2O), nitric oxide (NO), and ammonia (NH3)) emissions during wheat cultivation.Materials and methodsWe conducted a field experiment in Zhuzhen (Jiangsu), China, from November 2018 to May 2019 to examine the effects of effluent and manure on gas emissions from the wheat fields that had seven treatments (4 replicates, 28 plots): no fertilizer (control); inorganic fertilizer at a conventional application rate of 200 kg N ha−1(NPK); 100 kg N ha−1inorganic fertilizer plus 100 (DE1), 150 (DE2), and 250 (DE3) kg N ha−1farm dairy effluent; 100 kg N ha−1inorganic fertilizer plus 100 kg N ha−1farm dairy manure (SM1); and 150 kg N ha−1inorganic fertilizer plus 50 kg N ha−1farm dairy manure (SM2).Results and discussionApplying dairy effluent during the wheat season significantly (P <0.05) increased NH3emissions from 1.83 (NPK) to 3.81 kg N ha−1(DE1) and 11.4 kg N ha−1(DE3), probably due to elevated levels of soil NH4+and pH, with no discernable impact on N2O emissions compared with NPK. The greater application of effluent in the DE3 treatment increased NO emissions significantly by 33.3% relative to NPK. The combined application of manure and urea significantly reduced N2O and NO emissions by 25.2–27.6% and 8.3–45.8%, respectively, but increased NH3emissions in the SM1 treatment by 73.8%, when compared with NPK.ConclusionsOverall, our results suggest that replacing 25% of the current conventional chemical N application rate with dairy manure could considerably mitigate gas emissions in the wheat season.
