摘要
利用氮素营养诊断技术指导施肥,不仅能最大限度地提高肥料利用率,减少生产成本,还可减少肥料浪费并改善生态环境。氮素营养诊断技术主要包括传统诊断和无损诊断,都用来对作物生长、营养状况进行监测及诊断。但是不同的诊断方法适用范围各不相同,因此在选择时要注意。本文介绍了各氮素营养诊断技术的原理、研究现状及优缺点,重点阐述了氮素无损诊断技术的发展状况及在麻类作物上的应用前景。
Nitrogen Diagnosis Technologies which mainly include Traditional Nutrition Diagnosis Technologies and Non-Destructive Measurements are used to monitor and diagnose plant growth and nutrition situation, These technologies not only can enhance fertilizer absorption, decrease production cost, but also reduce fertilizer waste and improve environment. But they should be selected carefully because of their various usage and application scope. This paper introduced the theories, research status, advantages and disadvantages of Nitrogen Diagnosis Technologies. In addition, the development of Non-Destructive Measurements and their application prospect in fiber crops were introduced emphatically .
