通过较长时间小区试验，对水稻3种灌溉方法的产量、用水量、水分生产率进行了研究。结果表明：无水层灌溉与薄露灌溉、习惯灌溉相比，早稻分别增产651，990kg／hm^2，增产率为10．3％、16．5％；晚稻分别增产717，1175kg／hm^2，增产率为9．9％、17．4％。同时，灌溉水量早稻分别节水830，3150m3／hm^2，节水率为46％、69％；晚稻分别节水1410，2955m^3／hm^2，节水率为58％、74％。无水层灌溉早稻、晚稻水分生产率分别为2．67，2．94kg／m^3，达到了国际领先水平。
通過較長時間小區試驗，對水稻3種灌溉方法的產量、用水量、水分生產率進行瞭研究。結果錶明：無水層灌溉與薄露灌溉、習慣灌溉相比，早稻分彆增產651，990kg／hm^2，增產率為10．3％、16．5％；晚稻分彆增產717，1175kg／hm^2，增產率為9．9％、17．4％。同時，灌溉水量早稻分彆節水830，3150m3／hm^2，節水率為46％、69％；晚稻分彆節水1410，2955m^3／hm^2，節水率為58％、74％。無水層灌溉早稻、晚稻水分生產率分彆為2．67，2．94kg／m^3，達到瞭國際領先水平。

The water productivity of irrigation of rice had been resarched by 3 irrigation methods in the experimehtal plot formahy-yeares. The results showed that the yield of early rice saperate increased by 651 kg/hm^2 and 990 kg/hm^2, increased rate is 10.3% and 16.5%; the yield of late rice saperate increased by 717 kg/hm^2 and 1 175 kg/hm^2, increased rate is 9.9% and17.4%o At the same time early rice save water 830 m^3 and 3 150 m^3 per hactave, sare water rate is 46% and 69% ; late rice save water 1 410 m^3 and 2 955 m^3 per hectare, the rate is 58% and 24%. The water productivity of the irrigation of early riceand late rice saperate is 3.1 kg/m^3, have reach ed advanced level of international.
