农业生产中的氮肥施用现状及其环境效应研究进展

Research Progress of Nitrogen Fertilizer Application and its Environmental Effects in Agricultural Production

为提升氮肥利用率,提高农作物质量和产量,减少环境污染,分析了农业生产中氮肥的施用现状,指出了氮肥的不合理施用对土壤环境、水体环境、大气环境的影响,提出了降低氮肥对环境污染的策略:合理控制氮肥施用比例,提高氮肥利用率,改用新型肥料,代替部分氮肥的使用,制定氮肥施用管理标准,加强对氮肥施用的把控,实现种地与养地相结合,促进我国农业生产与环境的可持续发展。

In order to improve the utilization rate of nitrogen fertilizer,improve the quality and yield of crops and reduce environmental pollution,this paper analyzes the application status of nitrogen fertilizer in agricultural production,points out the impact of unreasonable application of nitrogen fertilizer on soil environment,water environment and atmospheric environment,and puts forward the strategies to reduce the environmental pollution of nitrogen fertilizer,i.e.to reasonably control the application proportion of nitrogen fertilizer,improve the utilization rate of nitrogen fertilizer,and use new fertilizer,instead of the use of some nitrogen fertilizer,formulate nitrogen fertilizer application management standards,strengthen the control of nitrogen fertilizer application,realize the combination of land cultivation and land cultivation,and promote the sustainable development of agricultural production and environment in China.
