Abstract: Through desertification of soil research on physical and chemical properties and mung beans grow Da′an in the west of Jilin province, the influence of the biochar on desertification soil physical and chemical properties and plant was analyzed, and the amelioration of biochar on desertification soil was also discussed. The results showed that biochar had obvious influence on desertification of soil organic matter content, pH value and available nitrogen, phosphorus and potassium content. At the same time, it could improve the water content of mung bean seedlings and promote the growth of its seedlings. 

Key words: biochar, desertification of soil, available elements, physical and chemical properties, plant growth
