| A study was carried out on the effects of different irrigation amount on irrigation water consumption and
soil water use eficiency of greenhouse cucumber with drip irrigation under film mulching in arid areas of Ningxia. The re-sults showed that: the water consumption increased with cucumber plant qrowth， the maximum time was at the fruit stage, and then it declined gradually. Under different treatments in each stage， the water consumption of cucumber in-creased after irrigation amount increased, while the soil water consumption reduced after irrigation amount increased. When the imigation amount was up to 563 mm，the irigation water could satisfy the needs of cucumber and had highest yield, and water use fficiency was 33.4 kg/m3. |
