中文摘要：

为了探索不同灌溉模式下施加控释肥对水稻的生长及产量的影响,试验设计了常规灌溉A和控制灌溉B、C三种灌溉模式,采用盆栽试验,分析了不同水氮管理条件下水稻的茎蘖、株高、叶面积指数（LAI）、产量、灌水量以及灌溉水分生产率的变化规律。结果表明,施用控释肥增加了水稻的分蘖数和LAI,但有效分蘖率比常规肥少,平均减少了13.46%。水稻分蘖期和抽穗-开花期水分胁迫对LAI影响较大,施加控释肥条件下灌溉模式A水稻LAI与灌溉模式C差异极显著（P〈0.01）,施加常规肥条件下灌溉模式A水稻LAI与灌溉模式C差异显著（P〈0.05）,水分胁迫条件下,控释肥对LAI的影响比常规肥更加明显。施加控释肥条件下,灌溉模式B、C的产量分别比灌溉模式A减少1.67%、5.77%;施加常规肥条件下,灌溉模式B、C的产量分别比灌溉模式A减少1.19%、4.24%。与常规施肥相比,施用控释肥提高了水稻的产量,但总灌溉水生产率比常规肥低0.1kg/m3。

英文摘要：

In order to explore the effects of controlled release fertilizer on rice growth and yield in different irrigation modes,pot experiments were conducted with three types of irrigation modes：conventional irrigation A and controlled irrigation B,C,and the variation of the stems and tillers of rice,plant height,leaf area index,yield,irrigation volumes and the productivity of irrigation water were analyzed under different conditions of water and fertilizer management.The results showed that the application of controlled release fertilizer could increase the numbers of rice stem and leaf area index,but the effective tiller rate was less than the application of traditional fertilizer,which reduced by 13.46% on average.In the rice tillering stage and heading flowering stage,water stress had great effect on LAI.There were very significant differences（P〈0.01）between irrigation mode A and irrigation mode B on LAI under the condition of applying controlled release fertilizer.There were significant differences（P〈0.05）between irrigation mode A and irrigation mode B on rice LAI under the condition of applying traditional fertilizer.The effect of controlled release fertilizer on rice LAI was more obviously than that of traditional fertilizer in water stress.Under the condition of applying controlled release fertilizer,the yield of irrigation mode C and irrigation mode B decreased by 1.67% and 5.77% respectively compared with irrigation mode A.Under the condition of applying traditional fertilizer,the yield of irrigation mode C and irrigation mode B decreased by1.19% and 4.24%respectively compared with irrigation mode A.Compared with traditional fertilization,the application of controlled release fertilizer increased the yield of the rice,but its productivity of the total irrigation water was 0.1kg/m3 lower than that of traditional fertilizer.
