| 摘 要： | 5年田间试验研究不同气候年型下灌水次数、灌溉时间对夏玉米生育、产量和水分利用效率的影响结果表明 ,随生育期总耗水量的增加 ,夏玉米产量逐步提高 ,当耗水量增至一定程度时产量反而递减 ;而水分利用效率随耗水量的增加呈逐步递减趋势。并确定了夏玉米最优耗水量 ,建立了不同降水年型下夏玉米优化灌溉制度。 |
| 关 键 词： | 夏玉米 水分亏缺 优化灌溉制度 水分敏感指数 |

| Abstract: | Results from five years' field experiment show that the water consumption of maize with grain yield is not li- nearly correlated. The increase in water use is not always resulted in the increase of production and the water use efficiency is reduced with the increase in total water use. The sensitivity to water stress at different growing periods of maize and the lower limit of soil moisture can be used as the indicators to irrigate efficiently. Based on the results, irrigation scheduling under different types of years is set up for maize. |
| Keywords: | Maize Water deficit Optimized irrigation scheduling Sensitivity index to water |
