1Effects of the nitrification inhibitor nitrapyrin and tillage practices on yield-scaled nitrous oxide emission from a maize field in Iran显示文摘Nitrification inhibitors can effectively decrease nitrification rates and nitrous oxide(N_(2)O)emission while increasing crop yield under certain conditions.However,there is no information available on the effects of nitrification inhibitors and tillage practices on N_(2)O emissions from maize cropping in Iran.To study how tillage practices and nitrapyrin(a nitrification inhibitor)affect N_(2)O emission,a split factorial experiment using a completely randomized block design with three replications was carried out in Northeast Iran,which has a cold semiarid climate.Two main plots were created with conventional tillage and minimum tillage levels,and two nitrogen(N)fertilizer(urea)management systems(with and without nitrapyrin application)were created as subplots.Tillage level did not have any significant effect on soil ammonium(NH_(4)^(+))and nitrate(NO_(3)^(-))concentrations,cumulative amount and yield-scaled N_(2)O emission,and aboveground biomass of maize,whereas nitrapyrin application showed significant effect.Nitrapyrin application significantly reduced the cumulative amount of N_(2)O emission by 41%and 32%in conventional tillage and minimum tillage practices,respectively.A reduction in soil NO_(3)^(-)concentration by nitrapyrin was also observed.The average yield-scaled N_(2)O emission was 13.6 g N_(2)O-N kg^(-1)N uptake in both tillage systems without nitrapyrin application and was significantly reduced to 7.9 and 8.2 g N_(2)O-N kg^(-1)N uptake upon the application of nitrapyrin in minimum tillage and conventional tillage practices,respectively.Additionally,nitrapyrin application increased maize biomass yield by 4%and 13%in the minimum tillage and conventional tillage systems,respectively.Our results indicate that nitrapyrin has a potential role in reducing N_(2)O emission from agricultural systems where urea fertilizers are broadcasted,which is common in Iran due to the practice of traditional farming.Azam BORZOUEI Ulo MANDER Alar TEEMUSK Alberto SANZ-COBENA Mohammad ZAMAN Dong-Gill KIM Christoph MÜLLER Ali Askary KELESTANIE Parvaneh SAYYAD AMIN Ebrahim MOGHISEH Khadim DAWAR Ana Gabriela PÉREZ-CASTILLO 2021Pedosphere2021,31,2:4
2中低收入国家的慢性病:背景、决定因素与卫生政策显示文摘近年来,中低收入国家慢性病不断上升的趋势及其产生的影响受到广泛关注,但有关这种上升趋势的解释和说明大多基于高收入国家的慢性病发展史,但其所经历的发展历程与中低收入国家并不完全相同。本文对这些差异进行评价,以更好地理解中低收入国家慢性病的流行趋势,并对慢性病决定因素的相关理论加以讨论,为慢性病的防控提供循证支持。此外,本文将慢性病防控政策看作是降低人口患病风险和个体易感性的重要干预手段,并讨论了中低收入国家需要开展的相关政策研究。在此基础上进一步强调了加强初级卫生保健改革的必要性,并将其作为降低慢性病流行趋势的一项重要政策。Miranda J J Kinra S Casas J P Davey Smith G Ebrahim S 2013中国卫生政策研究2013,6,10:2
