Saline-alkali soil sustainable use and improved technologies Liu xx Abstract: The development and utilization of saline-alkali soil has a significant contribution to food proction. However, the lack of water resources, climate change, development and utilization of saline-alkali soil more challenging. The article summarizes the sustainable use of saline-alkali soil in recent years research has made important progress. Improved governance saline-alkali soil, and promote efficient use of saline agriculture to ensure food security and promote sustainable development of agriculture is one important way. The progress and development of agricultural science and technology, continue to maintain and improve access to saline-alkali soil in agricultural proctivity. Of saline soil area of about 34.6 million hectares, 7.6 million hectares of arable land salinization,
