| 摘 要： | 通过筒测试验,研究了玉米最佳的水分调亏阶段以及各调亏阶段亏水程度的最佳上、下限阈值。结果表明,抽穗开花期水分亏缺对产量影响最大,其次是拔节期,苗期水分亏缺对产量影响最小。苗期、拔节期和抽穗开花期水分亏缺程度分别为50%FC～60%FC、65%FC～75%FC和65%FC～75%FC的灌溉处理是最佳调亏灌溉方案,产量与水分利用效率比正常灌溉处理提高了8%、12.6%。 |

| Abstract: | Optimum water deficit stage and the thresholds of optimum upper and lower limit of water deficit degree in each water deficit stage were studied using pot experiments.The results showed that water deficit at heading stage affected yield mostly,followed by that at jointing stage,and the least at seedling stage.The best irrigation scheme was that the level of water deficit were respectively 50%FC-60%FC、 65%FC-75%FC and 65%FC-75%FC at seedling stage,jointing stage and heading stage of maize.Compared with the normal irrigation treatment,the yield and the water use efficiency increased by 8% and 12.6%. |
