摘  要:对我国目前烟草氮肥施用量过高而肥料利用率较低的现状进行了分析,介绍了提高氮肥利用率的传统方法,包括氮肥深施、合理施用氮肥、肥水调控技术、平衡施肥。重点提出了施用控释氮肥、实时氮肥管理、精准施肥的新技术。High application ratio and low utilization ratio of tobacco nitrogen in China were analyzed. Several traditional methods of increasing nitrogen use efficiency were reviewed including nitrogen deeply application, proper nitrogen application, fertilizer-water controlling techniques and balanced fertilization. The new techniques of controlled release nitrogen application, real-time nitrogen management and precision fertilization were emphasized, and future prospect of increasing nitrogen use efficiency was also proposed.
