Study on Application of Newly Weter-Saving Irrigation Control

In Soil-Plant-Atmosphere Continuum an automated irrigation control system, based on the microgrowth and water content change of plant stem and fruit as water-requiring information, can maintain green plants a proper water deficit and adjust their microgrowth effectively. Experiment showed that, compared with the plants well irrigated, corn and orange fruit grew well when the decrease of irrigated water reached 15.6% and 21.4%, respectively.
