Liu xx saline-alkali land sustainable utilization and improved technology abstract: saline-alkali land resources development and utilization has an important contribution to food production.But the lack of water resources, climate change, make the development and utilization of saline-alkali work more challenging.The article system in recent years are summarized the important progress was made in saline-alkali land sustainable utilization research.Saline-alkali land improvement of saline-alkali land management, and promote agricultural efficient use is the guarantee food security, one of the important ways to promote agricultural sustainable development.Through agricultural science and technology progress and development of saline-alkali land access to continue to maintain and improve the agricultural productivity.In saline soil area of about 34.6 million hectares, 7.6 million hectares arable land salinization, nearly 1/5 of the cultivated land salinization-alkalization, alkali-saline land use of the development of technology, especially in China, arid agriculture irrigation area of sustained and healthy development of rural economy, land management, ecological environment protection has extremely important practical significance.From improvement of saline-alkali water conservancy, agriculture and three aspects of chemical and biological technology, are reviewed in this paper saline-alkali improvement of technology, and put forward "foster strengths and circumvent weaknesses, comprehensive treatment" alkali-saline land.
