摘　　要：试验设井间控、井间歇、渠间控、渠间歇四个不同灌溉方式,进行处理间不同时期灌水量、土壤温度的日变化、气温与土壤温度的关系、井水灌溉不同时间内水温的变化、产量性状的调查,研究不同灌溉方式对水稻生育及产量的影响、公顷效益的分析,结果表明:①从整个生育期用水量分析,井间控与渠间控比井间歇与渠间歇节水,分蘖期、长穗期节水量最大。井间控比渠间歇节水21.2%,比井间歇节水18.2%。②井间控利用了快、少灌水原则,利用大面积田面进行晒水,与井间歇相比,增温速度快,增温幅度大,增温效果好。③井间控有较明显的节水和增产效应,是较理想的节水灌溉方式。In this experiment,we designed Well-intetcontrolled,well intermittently,drainage intetcontrol,drainage intermittent irrigation at four different ways to deal with the volume of water between the different periods of time,analysed the daily change of soil temperature,air temperature and soil temperature,water for irrigation in water temperature at different times changes in dry matter accumulation and yield traits.In addition,we also investigated research of different irrigation methods on growth of rice and yield,ha-effectiveness analysis.The results show that： ① The entire reproductive period of consumption analysis,well-intetcontrolled than in well-controlled and intermittent drainage with intermittent drainage water,tillering stage,saving the largest amount of long-heading stage.Well-intetcontrolled intermittent drainage of water-saving more than 21.2 percent,saving more than 18.2 percent of intermittent wells.②Well-intetcontrolled use a faster and less water in principle,the use of large area field drying surface water,and wells,compared to intermittent warming faster rate of warming,and warming effect.③Well intetcontrol is a better way of water-saving irrigation and more visible in the water-saving and yield-increasing effect.
