Abstract:

This paper provides an overview of research into deficit irrigation in China focusing on the high water use efficiency of crop species grown under moderate water supply. Both the soil water retention curve and the relationship between soil water and stoma have a "platform effect", that enables medium crop yield to be achieved at low irrigation quota, thereby realizing water savings and yield increases. Models of crop response to water from other countries are being adapted to Chinese conditions, these include: the lag effect of water stress, crop response to salt water, crop yield model based on remotely sensed water deficit, crop photosynthesis and model of crop response to water.
