设施农田氮素高效利用与减排技术研究

Study on Nitrogen Efficient Use and Emission Reduction Technology in Facility Farmland

从投入控制技术、农田管理技术、作物品种改良优化等方面,对农田氮素高效利用技术进行研究,并从氮素捕获和循环利用、污水灌溉和农田红色虾蟹养殖、氮素沉降和氮氧化物减排技术等方面,探索农田氮素减排技术,以氮素高效利用和减排为目标,以期为农田氮肥管理提供科学依据。

The technology of efficient use of nitrogen in farmland was studied from the aspects of input control technology,farmland management technology,crop variety improvement and optimization.From the aspects of nitrogen capture and recycling,sewage irrigation,red shrimp and crab farming,nitrogen deposition and nitrogen oxide emission reduction technologies,the field nitrogen emission reduction technologies were explored,aiming at efficient nitrogen utilization and emission reduction,in order to provide scientific basis for the management of nitrogen fertilizer in the field.
