| 摘 要： | 保雨灌溉技术的核心是向天空要水,与蒸发夺水,充分利用自然降水和土壤水分,满足作物需要。在作物需水不足时,提取地下水补充灌溉。三年试验结果表明,保雨灌溉比常规井灌年均节水2091mm/hm~2,增产粮食2020kg/hm~2,促进了优质高效农业的发展。

| Abstract: | The kernels of the rain conservation irrigation technology are increasing effective rain- fall, decreasing evaporation and sufficiently using soil water to satisfy the crops demands. The ground- water can be lifted as a supplement irrigation in the condition of crop water demands shortage. The ex- periments of three years have shown that the rain conservation irrigation can save 2091mm/hm~2 of water and increase 2020 kg of food yearly camparied with the conventional well irrigation. Those may promote developing the high quality and effecient agriculture. |
