The Conception and Technology Discussion of Modern Water Saving Agriculture

Based on the agricultural production history,the authors analyzed the relationship between the irrigation agriculture and water saving irrigation technology,rain-fed agriculture and dry-land water efficient use technology,water saving agriculture and technology,and put forward and discussed the conception of modern water saving agriculture and its technology,and set up preliminarily the modern water saving agriculture system.The authors point out that the modern water saving agriculture is a new agricultural production way aiming at promoting the integrated profit to precise provide water and intellective allocate water to plant to maintain its life safety and reduce the useless water during plant water use and water supply under the premise of ensuring the ecological and environmental health.7 technologies constitute the modern water saving agriculture,including the distinguish the water saving plant breed,process control during the water requirement for health plant life,precise water supply,soil water conservation and evaporation reduction on the interface of soil and atmosphere,plant water circle use,untraditional water plant use,and the regional intellective allocate water technologies.
