Progress and Prospect of Saline-Alkaline Soil Management Technology: A Review

Abstract

Saline-alkaline and alkaline land is an important potential cultivated land resource in the world. With the destruction of the ecological environment, the cultivated land area is less and less. As a potential soil conditioner, wood vinegar can adjust soil pH, increase root activity, and promote seed germination and root growth, showing its potential in improving saline-alkaline soil. This review summarizes the present situation of saline-alkaline and alkaline land, and its application to China’s cultivated land policy. The traditional saline-alkaline and alkaline land management measures, and analyzes the advantages and disadvantages. Some new methods of treating saline-alkaline soil were enumerated, and the methods of treating saline-alkaline soil with wood vinegar were emphatically introduced, and the molecular mechanism of action of wood vinegar was discussed, the effects of long-term application of wood vinegar on the stability of soil ecosystem were analyzed. The prospect of comprehensive management of saline-alkaline land and how to balance economic development were proposed.
