新疆干旱区盐碱地生态治理关键技术研究

现阶段新疆干旱区高强度水土资源开发,致使传统灌排水盐平衡模式难于维继;高效节水灌溉技术应用改变农田土壤水盐运移规律,需要创新调控理论与技术体系;传统盐碱地农业开发利用模式资源效率低、维持成本高,需要以生物修复技术为核心构建盐碱地高效率资源化利用模式。针对上述问题,在国家重点研发计划(2016YFC0501400)的资助下,通过机理研究、关键技术研发、产品研制、县域集成示范实现:(1)建立新疆干旱区现代水盐平衡调控理论,(2)创新干旱区盐碱地生态治理模式,(3)建成盐碱地产业化集成示范区,形成全产业链的盐碱地生态治理技术服务体系,(4)稳定一支以新疆相关单位为主体,国内优势单位参与的根植新疆的盐碱地生态治理队伍。

Study on key technologies of ecological management of saline alkali land in arid area of Xinjiang

The traditional irrigation water salt balance model is difficult to maintain under the high strength development and utilization of soil and water resources in arid area of Xinjiang at the present stage. The soil water and salt migration of farmland is changed under the application of efficient water-saving irrigation technology, so need theory and technology system innovation. Improvement mode of saline alkali land saline with low efficiency, high cost of maintenance resources and development of traditional agricultural regulation, need to biology repair technology as the core of the utilization of saline land resource efficiency model. Aiming at the above problems, and under the support of the state key development program (2016YFC0501400), through the mechanism research, key technology research and development, product development, the integrated model:(1) the establishment of water salt equilibrium regulation theory of Xinjiang arid region, (2) innovative arid saline land ecological management model, (3) built in saline estate industry integration demonstration area, the service system of the formation of the whole industry chain of saline alkali soil ecological control technology, (4) stability of a salt and alkali land in Xinjiang ecological management team.
