Cultivated land is the fundamental guarantee of food security, and saline-alkali land affects the quality of cultivated land to varying degrees. It is of great significance to study saline-alkali land improvement measures to solve the problem of saline-alkali land utilization, promote the healthy development of agriculture and animal husbandry, and improve the quality of cultivated land. The author has sorted out the relevant literature and reports on the improvement methods and technologies of saline-alkali land at home and abroad in recent years, and introduced the status and effects of different improvement measures for saline-alkali land from four types: chemical improvement measures, physical improvement measures, water conservancy improvement technology and biological improvement measures. It provides a theoretical basis for the study of governance and saline-alkali land improvement measures.
Key words: Saline-alkali land / improvement measures / research status
