| 摘 要： | 对宁夏引黄灌区玉米不同灌溉定额的试验研究表明,适当灌水可明显提高玉米产量,灌水3次、灌水定额为3150 m3/hm2时面积产量最高,为13.3 t/hm2.灌溉定额在0~4200 m3/hm2的范围内,玉米的总耗水量在2741~6559 m3/hm2之间.产量最高时的耗水量为5544 m3/hm2.根据灌溉定额-产量拟合曲线求得的玉米产量最高时的灌溉定额为3501 m3/hm2.籽粒水分利用率在3.31~1.98 kg/m3之间. |
| 关 键 词： | 玉米 产量 灌溉定额 耗水特征 |

| Abstract: | The experiment result of different irrigating quota for maize in Yellow River irrigation area of Ningxia showed that the yield of the maize were!increased obviously under suitability irrigation condition,and when the maize were irrigated three times and with irrigating water quota of 3 150 m3/hm2,the yield was highest which was 13 252 kg/hm2.The total water consumption quantity of maize was from 2 741 m3/hm2 to 6 559 m3/hm2 when irrigating quota between 0 and 4 200 m3/hm2.The water consumption for highest yield was 5 544 m3/hm2 while the irrigating quota was 3 501 m3/hm2,and the water using efficiency of maize was between 3.31 kg/m3 and 1.98 kg/m3. |
| Keywords: | maize yield irrigating quota water consumption characteristic |
