摘要
干湿交替灌溉是一项重要的水稻高产节水栽培技术。干湿交替改变了稻田土壤水分状况,从而会引起稻田土壤理化和生物学性状的改变,并直接或间接影响水稻的生长发育和产量形成。综述干湿交替灌溉对水稻产量、品质以及稻田土壤呼吸、土壤酶活性和微生物等生物学性状的影响,并提出未来干湿交替灌溉条件下稻田土壤生物学性状的研究重点,以期为水稻高产节水栽培和稻田土壤的定向调控提供理论依据。
Alternate wetting and soil drying irrigation （AWD） is very important for the development of water-saving irrigation and the improvement of rice yield. The change of soil moisture in paddy field could lead to the changes of soil physical and chemical characters and biological characters, and affect the growth and yield of rice directly or indirectly. This paper reviewed the effects of AWD on rice yield, grain quality and biological traits of soil, including soil respiration, soil enzyme activity and microorganisms. Some research priorities on the effect of AWD on soil biological characteristics in the future were also put forward to provide the theoretical basis for high yielding, water saving and directional control of paddy soil in rice cultivation.
