Technique innovation and research fields of modern agricultural and ecological water-saving in the future

Scientific problems which China have expenenced in the region of agricultural and ecological water-saving techniques and differences in the level of technology between China and advanced country were put forward. Such as experimental facility conditions, water-saving irrigation technology and equipment exploitation, precision irrigation, irrigation system automatic control, poor quality water resource utilization, regional agricultural water resource management and so on. The development tendency of agricultural and ecological water-saving techniques were analyzed on surface irrigation, micro-sprinkler irrigation, tools and materials of water-saving facilities, sewage irrigation, canal seepage prevention and precision irrigation. Aims and important research projects of agricultural and ecological water-saving technology innovation in China were also raised. The construction of guaranteed conditions for agricultural and ecological water-saving technology innovation was discussed.
