河西节水农业的现状评价与重点领域研究

发展节水农业是实现绿洲灌区发展现代农业和建立资源节约型社会的必然选择。研究表明,河西走廊区节水农业现状是:工程节水技术是农业节水的主流技术,农艺节水技术缺乏核心,管理节水技术与实践存在脱节,各类技术的组装集成不足。该区农业节水的重点研究领域是:以水权和水资源优化配置为核心的管理节水技术体系研究,以地面改进、保护性耕作和覆盖技术为主的农艺节水技术研究,以废水、劣质水开发利用为主的开源节水技术和设施节水技术。

Current Status and Key Fields of Water-saving Agriculture in Hexi Corridor

Water saving agriculture is the main part of the modern agriculture in oasis area,and it is the necessity for resources efficiently utilized society.Investigation show that,in current,the engineering water-saving technique is the mainstream of the water-saving agricultural techniques.Management technique disjoint with practice,lack of key technique and integration of different type of water-saving agriculture are the main problems.In the future,the main research fields of water-saving agricultural technique as following:the management technique that characterized by optimizing scheme of water resources and water right,the agronomy technique depends on ground suface improving and conservation tillage with mulching,the water source opening up technique that rely on using waste water and inferior quality water,as well as the technique used in greenhouse.
