Research Progress on Response of Rice Root Morphology and Physiology to Alternate Wetting and Drying Irrigation
The morphological and physiological characteristics of crop root system play an important role in the growth and development of aboveground part and the formation of yield.Rice is the largest water user in agriculture,and the shortage of water resources is bound to seriously affect the development of rice production.As a water-saving irrigation method,alternate wetting and drying irrigation technology is widely used in rice production at present.However,there is a lack of systematic analysis and summary on how rice root growth and development respond to alternate wetting and drying irrigation,and what its internal mechanism is.Therefore,this paper reviewed the technology of alternate irrigation and the morphological and physiological characteristics of rice roots,analyzed the response mechanism of root growth and development to dry and wet alternating irrigation,and put forward the existing problems and prospects for future research.
