Research Progress on Carbon Footprint of Biogas Slurry Application in Rice-Wheat-Rapeseed Rotation Systems
摘要
Abstract
Biogas slurry,as a new type of organic fertilizer,has shown remarkable effects in crop production.It can replace high-carbon-foot-print synthetic nitrogen fertilizers and promote the sequestration of soil organic carbon,demonstrating significant carbon reduction potential,es-pecially in dry land systems(wheat,rapeseed).However,in irrigated rice cultivation systems,the easily degradable organic matter in biogas slurry significantly promotes methane(CH4)emissions,constituting the main carbon risk of the system.Meanwhile,all rotation systems have the risk of nitrous oxide(N2 O)emissions,and the overall carbon footprint shows significant management dependence.To Systematically reveal the carbon footprint characteristics of biogas slurry in rice-wheat-rapeseed production and efficiently develop and utilize biogas slurry,systemati-cally reviewed the current status of the development and utilization of biogas slurry,the carbon emission characteristics in rice-wheat-rapeseed production,and research progress.More important the future research directions were prospected,including through multi-dimensional analysis of the carbon-nitrogen-water coupling mechanism,construction of a digital decision support system,multi-objective collaborative assessment,and innovation of a green policy system,a paradigm shift from single carbon accounting to multi-ecosystem service value assessment can be a-chieved,thereby promoting the transformation of biogas slurry from a potential carbon source to a precisely controllable low-carbon agricultural resource.This aim of the paper is to provide an updated theoretical basis and technological support for the green and low-carbon transformation agriculture in China.关键词
