基于光谱分析的节水灌溉方法研究

Research of a Water Saving Irrigation Approach Based on Spectral Analysis

针对传统的植物亏水指标测定不精确,造成灌溉过程中水资源浪费问题,提出利用植物冠层光谱信息定量反演植被含水量信息,同时结合滴灌控制系统实现精准、智能节水灌溉的技术路线及方法,从而提高灌溉水的利用效率,节约水资源,降低成本,达到真正节能节水目的。

In view of the traditional plant water deficit index measurement imprecision to result in irrigation water resource waste,an approach is presented to complete precision and intelligent water saving irrigation with inverting quantitatively plant water content information by plant canopy spectral information.This approach can improve the water use efficiency of irrigation,save water resource and reduce the cost to achieve the goal of really saving energy and water.
