中文摘要	以畦灌玉米为研究对象,利用彭曼公式计算玉米理论需水量,并结合作物根层贮水量、生理指标及产量等确定宁夏中部干旱带玉米畦灌灌溉制度。结果表明,研究区年参考作物腾发量为1 112 mm,玉米生育期需水量为596 mm,理论灌溉水量为4 132 m~3/hm~2;30~60 cm是玉米根区主要贮水层;灌水后各水分处理光合有效辐射均下降,12:00、14:00降幅分别为13.7%~24.6%、1.8%~5.9%。玉米抽雄期光合速率及蒸腾速率日变化趋势一致,均呈单峰曲线,并于10:0014:00出现峰值。灌溉定额为3 900 m~3/hm~2时,产量最高,为14 860.5 kg/hm~2;灌溉定额为3 300 m~3/hm~2时,水分利用效率最高,为4.13 kg/m~3。宁夏中部干旱带畦灌玉米最优灌溉制度为:全生育期灌水4次,灌水定额为975 m~3/hm~2,灌溉定额3 900 m~3/hm~2。
英文摘要	The theoretical water requirement of corn under border irrigation was calculated by Penman formula. According to water storage in root zone, physiological index, yield and theoretical water requirement, the irrigation system was determined. The results showed that the yearly reference evapotranspiration was 1 112 mm, the water requirement of corn in the growth period was 596 mm and the theoretical irrigation water amount was 413 mm. The main storage layer in corn’s root zone was in 30~60 cm. Photo-synthetically active radiation in different treatments all decreased after irrigation, and decreasd by 13.7% ~24.6%,1.8% ~5.9% at 12 am and at 2 pm respectively. The photosynthetic rate and transpiration rate changed similarly in maize tasseling with single peak curve at 10 am~2 pm. The yield was the top of 14 860 kg/hm~2 with irrigation quota of 390 mm while water use efficiency was the top of 4. 13 kg/m~3 with irrigation quota of 330 mm. The optimal irrigation system of corn in the central arid area of Ningxia is that irrigation quota is 390 mm, irrigating for 4 times during the whole growth period.
