摘　　要：为了探讨辽宁中部地区适宜的水稻灌溉方式,采用测坑试验,以浅水灌溉为对照,研究了控制灌溉、交替灌溉、浅湿灌溉和浅水灌溉4种灌溉方式下水稻的灌水量、株高分蘖、产量及水分生产率变化。结果表明,浅水灌溉和浅湿灌溉的灌水量、株高、有效分蘖数、产量和水分生产率显著高于控制灌溉和交替灌溉,浅湿灌溉的水分生产率最高,交替灌溉的水分生产率最低。辽宁中部最适宜推广的水稻灌溉方式是浅湿灌溉。Test pit experiments were conducted to discuss the suitable irrigation mode for rice in middle area of Liaoning Province. Variation of irrigation quantity, plant height and effective tiller, yields and wa- ter productivity were analyzed under four irrigation modes including controlled irrigation, alternative irri- gation, wet-shallow irrigation and shallow basin irrigation respectively, and shallow basin irrigation was used as control. The results showed that irrigation quantity, plant height, effective tiller, yields and water productivity of wet-shallow irrigation and shallow basin irrigation treatments were significantly greater than those of controlled irrigation and alternative irrigation treatments, water productivity of wet-shallow irrigation treatment was the best, and water productivity of alternative irrigation treatment was the least. The most suitable irrigation mode for middle area of Liaoning Province was wet-shallow irrigation.
