Abstract: Saline-alkali land is an important reserve cultivated land resource in China. The development and utilization of saline-alkali cultivated land has important practical significance for meeting population and food needs of as well as agriculture long-term sustainablility. Straw returning can improve soil structure and fertility,improve the quality of cultivated land,and reduce the salt accumulation in topsoil,making it an effective measure for improving saline-alkali soil. This paper summarized the current state of domestic straw returning technology,explained the principle and application of straw returning technology to improve saline-alkali soil,and discussed the effects of improvement on saline-alkali soil from the aspects of soil physical properties,chemical properties,biological characteristics and crop yield. The impact of improved saline-alkali straw returning technology application foreground was prospected.

Key words: Straw returning, Saline-alkali land, Soil improvement, Soil characteristics
