Saline alkali soil is a common form of soil degradation. Soil salinization is an important factor restricting the sustainable development of agriculture in irrigated agricultural areas in the world. Soil salinization improvement materials and technologies have always been a research hotspot. Based on the data source of CNKI, through setting key search words and years, searching relevant literature and patents, using bibliometric method, and drawing and tabulating tools such as origin and excel, the data were statistically analyzed. The results showed that the literature related to saline alkali land improvement technology was first published in 1957, and then increased year by year. Ningxia University was the institution that publishes the largest number of related scientific and technological papers. Wei Kunfeng, from Dezhou saline alkali soil greening Research Institute of Shandong Province, was the researcher with the largest number of related scientific and technological papers. Most of them belong to the field of Engineering Technology (nature). Most of the papers were supported by National Natural Science Foundation, National Science and technology support plan and other national fund projects Ningxia Hui Autonomous Region holds the most published papers.
