氮素营养诊断技术的发展及其在花生上的应用

Development of Nitrogen Diagnosis Technology and Its Application in Peanut

氮素营养不仅是限制各种农作物的产量和品质的关键因素,同时又是影响农田生态环境的重要因素。运用氮素营养诊断技术指导氮肥的合理使用,不仅能提高氮肥的利用率,降低生产成本,还可以减少环境污染的风险。氮素营养诊断技术包括传统诊断技术和无损诊断技术。介绍了多种氮素营养诊断的方法,并对其优缺点、应用现状和发展前景进行了综述,此外,还分析了在花生生产中进行氮素营养诊断的必要性及其重要意义,并在此基础上阐述了氮素无损诊断技术在花生上的应用以及展望。

Nitrogen nutrition is not only a key factor in limiting the yield and quality of various crops, but also an important factor affecting the ecological environment of the farmland. Use nitrogen diagnostic technology to guide the rational use of nitrogen fertilizer, not only improve the utilization of nitrogen, reduce production costs, but also reduce the risk of environmental pollution. Nitrogen diagnostic technology includes traditional diagnostic techniques and non-destructive diagnostic techniques. This paper introduces a variety of nitrogen diagnosis, and summarizes its advantages and disadvantages, application status and development prospects. In addition, the necessity of nitrogen diagnosis in peanut production and its significance is analyzed. Based on this, the application and prospect of nitrogen lossless diagnosis technology in peanuts are described.
