摘 要:玉米作为我国种植面积广泛的粮食作物之一,提高氮肥利用率是实现玉米高产优质的必然趋势。生物炭孔隙发达、吸附性好、官能团种类多样、阳离子交换能力强等特性,赋予了其改良土壤环境、提高氮肥利用率的潜力。该文在总结生物炭和氮肥利用现状的基础上,分析了生物炭对土壤氮素及质量的影响,以及生物炭配施氮肥对玉米产量及氮效率的影响,并展望了生物炭配施氮肥在玉米生产上的应用前景,旨在为生物炭与氮肥配施在农业生产上的应用提供参考。As one of the grain crops with a wide area of cultivation in China,improving the utilization rate of nitrogen fertilizer is an inevitable trend of high-yield and high-quality development of corn.The characteristics of developed biochar pores,good adsorption,a variety of functional groups and strong cation exchange ability give it the potential to improve the soil environment and improve the utilization rate of nitrogen fertilizer.Based on the summary of the current situation of biochar and nitrogen fertilizer utilization,this paper summarizes the effect of biochar on soil nitrogen and quality,briefly describes the impact of combined application of biochar and nitrogen fertilizer on maize yield and nitrogen efficiency,and analyzes the application and prospect of combined application of biochar and nitrogen fertilizer in maize production.It is designed to provide reference for the application of combined application of biochar and nitrogen fertilizer in agricultural production.
