@@@@With the economic development in China, the agricultural w ater use faces enormous chal enges, and therefore the en2 hancement of utilization efficiency of farm land wat er use in northern China is essential to solve the w ater shortage problem dur2 ing the food production process. In this paper, the research progress and development trend of the agronomic wat er2saving tech2 nology measures are analyzed, including the til age for soil moisture conservation, covering for soil moisture conservation, organ2 ic fertilizer and crop straw returning to soil, coupling of water and fertilizer, adjustment of crop layout, selection of water2saving varieties, and chemical control. In light of the achievements and existing problems on the agronomic w ater2 saving technology measures, some import ant theoretical problems and key technologies on the agronomic w ater2saving are proposed, w hich can help improve t he agronomic water2saving technology to a new height.
