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.
