摘　　要：通过不同时期、不同程度水分胁迫对水稻生态、生理、生化指标及生育状况影响进行试验研究,针对辽河中下游平原水稻生产,提出了不同湿润年的水分生产函数及相应的敏感指数;提出了非充分灌溉条件下的调优灌溉栽培技术。The effect of water stress at different stages and degrees on ecology, physiology and growing situation of rice varieties were studied and the water production function and water sensitivity index in rainy years were pointed out according to rice production situation in middle and lower reaches of the Liaohe River. The optimized water irrigation techniques were also demonstrated under inefficient irrigation conditions.

关 键 词：水稻 水分胁迫 水分生产函数 水分敏感指数 调优灌溉
