[Abstract]
With the development of China's economy, the agricultural water facing enormous challenges, to enhance farmland water use efficiency is essential to solve the problem of water shortage in the food production process. Comprehensive analysis on the research progress and development trend for the agronomic water-saving technology measures about tillage for soil moisture conservation, covering for soil moisture conservation, organic fertilizer and crop straw to soil, water and fertilizer coupling, adjust crop layout, selection of water-saving varieties and chemical control etc. In the light of the achievement and existing problems on agronomic water-saving technology measures, put forward some important theoretical problems and key technologies, with a view to agronomic water-saving technology promotes a new height.
