水稻不同灌溉方式节水效益的对比分析

Comparative Analysis of Water-saving Benefit among Different Irrigation Modes of Rice

根据江西省赣抚平原灌溉试验站1987—2003年水稻不同灌溉方式的对比试验资料，分析了间歇灌溉与浅水灌溉对水稻需水量、需水系数的影响。结果表明，在相同施肥水平和耕作措施条件下，间歇灌溉与浅水灌溉相比，可以降低水稻耗水量和水稻需水系数，提高水分生产率。

According to the comparative test data of different irrigation modes of rice in Irrigation Testing Station of Ganfu Plain during 1987 - 2003, the author analyzed the effects of intermittent irrigation and shallow water irrigation on water consuinption and water requirement coefficient. The results show that under the same fertilizer application amount and cultivation conditions, in comparison with shallow water irrigation, intermittent irrigation can decrease the water consumption and water requirement coefficient of rice, and increase water production rate.
