摘　　要：采用裂区设计,以吉粳511和吉粳809为试验材料,研究肥水耦合对盐碱地水稻产量及其构成因素的影响。结果表明:两个品种的肥料与水分处理间在每穗实粒数、千粒重、有效分蘖数、结实率和产量上均存在耦合效应。其中两个品种均以减氮22%,传统灌溉方式下水稻产量最高。间歇及控制灌溉均不利于盐碱地水稻稳产及增产。Adopting split-plot experiment design, and using ＇Jijing 511＇ and ＇Jijing 809＇ as material, effects of coupling of water and fertilizers on rice yield and yield components were studied. The results showed that for both varieties, fertilizer and water treatment have mutual effect on grain numbers per panicle, 1000-grain weight, effec- tive tiller number, seed rate and yield. When the N was reduced by 22%, the rice yield was the highest for tradition- al irrigation methods. Intermittent irrigation of and controlled irrigation was not conducive to increase and steady yield of rice in saline-alkali paddy field.
