摘　　要：文章根据2004～2006年黑龙江垦区水稻节水控制灌溉试验资料,分析了节水控制灌溉技术对水稻的节水效果。选择农垦牡丹江分局858农场267hm2水稻种植典型示范区为试验点,得出控制灌溉较常规灌溉全生育期少灌水3～4次,节水2400m3·hm-2,增产398kg·hm-2。同时,水稻米质,抗倒伏、抗病虫害效果比常规灌溉都有明显提高。发展水稻节水控灌技术,可合理有效地利用有限的水资源,节约灌溉用水,提高水分生产效率,发展节水型农业,对垦区粮食安全、农业生产发展和人民生活水平提高具有重要意义。This paper studied the performance of the rice water saving irrigation according to the data of rice water saving irrigation in Heilongjiang reclamation area in 2004-2006. The test was conducted at 276 hm^2 rice denontation area of the reclamation Mudanjiang office. The results showed that the control irrigation was less 3-4 times than ordinary irrigation, water saving was 2 400 m^3 ·hm^-2, yield was 398 kg·hm^-2. The quality, lodging resistance and disease and pests resistance were better than those of ordinary irrigation. The development of the rice water control irrigatiton technology can effectively use water resource, save the water and improve production efficiency of the moisture. Developing water-saving agriculture is important to grain security, agricultural production development and the increasing of living standards of people.
