节水灌溉控制中需水信号的述评

Survey of Thirst Signals in Water Saving Irrigation Control

节水、节能灌溉技术的关键之一在于寻求合理的节水灌溉控制信号.同张力计及其它传统方法相比较,依据植物生理需水信号控制灌溉具有更广阔的应用前景.

One crux of energy saving irrigation techniques is to investigate appropriate thirst signals of water saving irrigation control. Compared with conventional methods such as tensometor, the control of irrigation according to plant's thirst signal will show the potentiality in its application.
