Abstract: In this paper, we analyzed the formation reasons of soda saline alkali soil in Songnen plain, the migration mechanism of saline alkali in soil and the barrier mechanism of saline alkali, and suggested that we should reform the cropping system in accordance with the ecological law and scientific assembly cultivation technique system to establish a set of saline alkali soil integrate restoration high yielding cultivation technology system which includes straw coverage technology to control the soil moisture as the core, soil amendment technique, soil subsoiling technique to regulate soil physical and chemical properties, planting salt tolerant varieties, special foliar fertilizer technique and plant growth regulators (PGRs) technique to further regulate crop growth, which is to realize the unification of economic, social and ecological benefits.
