Abstract: The saline alkali area of Songnen Plain is the traditional main soybean producing area in the West of Heilongjiang Province. With the implementation of the No. 1 Central Document "Soybean Revitalization Plan" in 2019 and the No. 1 Central Document "Vigorously Implementing the Soybean and Oil Production Capacity Improvement Project" in 2022, the soybean planting area in this area has increased significantly, but the soybean yield has always been at a low level, which greatly limits the development of the soybean industry and the economic benefits of planting. This paper expounded the characteristics of soybean production in the saline and alkaline areas of Songnen Plain, the changes of average yield per unit area and planting area, the comparison of corn and soybean planting income, the application of main varieties and the establishment of high yield models by efficient technologies. To analyze the restrictive factors in soybean production such as soil fertility conditions, disease resistance and stress tolerance of varieties, intensive and standardized production, and low processing added value, and put forward suggestions and countermeasures for the development of soybean production to guide the scientific and efficient production of soybean in saline-alkali areas.
