猪粪沼液施用对稻田CH4和N2O排放及温室效应的影响
Effects of pig manure and biogas slurry application on CH4 and N2O emissions and their greenhouse effects on paddy field
摘要
Abstract
In order to treat waste superovulation by the large-scale cultivation in Jiangsu Province,which may cause serious environmental pollution and a massive waste of nutrient resource,emissions of CH4 and N2O from the paddy fields were measured in situ by using the method of static chambers and gas chromatographic techniques,and the greenhouse effect of CH4 and N2O was assessed by using global warming potential(GWP).The field experiment results clearly demonstrated that the GWP and GWP per unit yield were significantly increased by 385.5% and 422.4% under pig manure(100% PM) treatment,and by 218.2% and 228.4% under half pig manure and half chemical fertilizer(50% PM) treatment compared to chemical fertilizer(NPK) treatment,respectively.This can be explained that the value of CH4 emission from 100% PM and 50% PM treatments was significantly greater than that from NPK treatment,although the emissions of N2O from the paddy fields were significantly lower for 100% PM and 50% PM than that for NPK treatment.While,compared with NPK treatment,the values of GWP and GWP per unit yield were decreased by 27.8% and 29.5% under biogas slurry(100% PS) treatment,and by 15.4% and 18.8% under half biogas slurry and half chemical fertilizer(50% PS) treatment,respectively.Mainly for the reason that lower N2O emissions were obtained under 100% PS and 50% PS treatments compared with NPK treatment.As far as GWP,lower greenhouse effects are obtained in 100% PS and 50% PS treatments,while the breeding waste is reused in paddy fields in the rice-wheat rotation system.关键词
