不同施肥条件对稻田温室气体排放特征的影响
Impact of Different Fertilization Practices on Greenhouse Gas Emission from Paddy Field
摘要
Abstract
Greenhouse gas(GHG)emissions from agricultural production systems contribute largely to global warming. A field experiment was conducted to examine GHG emissions under three different fertilization practices(CT-urea alone, MT-80%urea plus 20%manure and OT-manure alone)in Shanghai suburb, China. Carbon dioxide, methane and nitrous oxide were collected and measured by static chamber-gas chromatography system. Compared to the control(CK), fertilization significantly increased carbon dioxide emission from paddy field, but no differences were found between fertilization treatments. Organic manure significantly increased methane emission, but greatly decreased nitrous oxide emission from paddy field. During the whole rice season, CK had the lowest seasonal Global Warming Potential(GWP)with 14 852 kg CO2·hm-2. Urea alone and organic manure alone and their combinations increased seasonal GWP by 86.9%, 134.3%and 111.5%, respectively, as compared with CK. The observed data demonstrate that fertilization could increase GHG emission and GWP from paddy field.关键词
