洱海流域有机肥全量替代化肥对稻田温室气体排放的影响
Effects of organic fertilizer substitution on greenhouse gas emissions in paddy fields in the Erhai watershed
摘要
Abstract
In the aftermath of the ban on the use of nitrogen and phosphorus fertilizer in the Erhai watershed,this study investigates the characteristics and key influencing factors of green manure,cow manure,pig manure,and chicken manure on greenhouse gas(N2O,CH4)emissions in rice fields.Rice field experiments were conducted in Gusheng Village,Dali City,Yunnan Province from 2021 to 2022.The greenhouse gas(N2O and CH4)emission characteristics were evaluated for six fertilization treatments:no fertilization(CK),green manure(Viciavillosa Rothvar)(GM),cow dung(CD),pig dung(PM),chicken manure(CM),and chemical fertilizer(CF).The N2O emissions of paddy fields,which mainly occurred within 1 week after fertilization,were reduced by 56.21%-72.39%(P<0.05).By contrast,CH4 emissions increased by 144.12%-355.76%(P<0.05).Both the greenhouse gas warming effect and emission intensity were found to increase significantly when using CF(119.65%-308.15%and 164.97%-318.96%,respectively).The greenhouse gas warming effect and greenhouse gas emission intensity of CD treatment was lower than those of the other organic fertilizer treatments.However,treatment with CD reduced the rice yield compared to that achieved using CF.CM achieved the highest yield[(10 220.32±954.53)kg·hm-2],with a warming effect and emission intensity that were lower than GM and PM.Soil temperature(0-5 cm),soil water content,soil inorganic nitrogen,air temperature,and rainfall are known to be key factors affecting greenhouse gas emission fluxes.Herein,total substitution of CM treatment achieved better results than the other organic fertilizer treatments,reducing the warming effect and emission intensity while facilitating stable crop production.关键词
