摘　　要：田间真实节水是通过调控作物的生理生长过程,减少无效耗水即土壤蒸发和奢侈蒸腾耗水的节水概念.本文针对陕西省关中灌区特殊的农业种植耕作模式,从真实节水的角度,提出了地面覆盖和合理的灌溉制度相结合的节水模式,以减少田间实际蒸腾蒸发量,提高灌溉水分利用效率.Real water-saving in the field means reduction of invalid water uses, such as soil evaporation and luxurious crop transpiration, by regulating crop physiological growth process. Comprehensive analysis of special agronomic practices and agricultural plant structure in the study area, resulted in several real water-saving ways which could be recommended for reduction in field evapotranspiration and improvement in water use efficiency, including soil mulching and appropriate irrigation regime.
