根据在黑龙江省庆安县和平灌区水稻灌溉试验站进行的田间试验，采用正交试验设计的方法，研究不同的灌溉方式、施氮肥比例和栽培密度对同一品种水稻产量和生理动态影响，从而寻求寒地水稻节水控灌水肥一体化管理技术模式。结果表明：水稻稀植和前氮后移的模式有利于水稻有效分蘖的形成，减少无效分蘖；灌溉方式对水稻产量和水分生产率的差异有极显著影响，其中控制灌溉Ⅱ各处理较当地常规灌溉各处理单产量最高提高11．78％，水分生产率最高提高30．56％，A2 B3 C2组合模式使水稻产量和水分生产率最高，是寒区水稻节水增产的最佳组合模式。

Accord to the field test in heilongjiang province Qingan Xian peace rice irrigation test station , different irriga-tion mode, nitrogen ratio and planting density technology on the same breed rice yield and physiological dynamic effect is study by orthogonal experiments design , so as to explore water-saving irrigation and fertilizer control in integrated ma nagement mode of technology .The results show that rice transplanting and INM mode are beneficial to form the effec-tive tillering in rice , reduce ineffective tiller;irrigation mode is the most significant influence on the rice yield and water productivity , single yield of each experimental treatment with control irrigation technology is taller than that with local conventional irrigation increased by 13.6%, water productivity increased by 21%, A2 B3 C2 combination mode making yield of rice and water productivity reaching the highest is a best water-saving and increasing yield combination mode on cold rice .
