The water-soluble fertilizer provided by the invention can improve activity of microorganisms in soil, has the performances of water and nutrient retention, soil improvement and the like, and improves fertility.

Description

technical field

[0001] The invention relates to the field of agricultural and forestry fertilizers, in particular to a microbial water-retaining water-soluble fertilizer for reclamation in rocky desertification bauxite mining areas and a preparation method thereof. Background technique

[0002] At present, Guangxi has a large area of ​​rocky desertification bauxite belt, which is mainly distributed in the Jingxi to Pingguo bauxite belt in Baise City. In the rocky desertification area of ​​Dashishan, especially the mining of bauxite has resulted in the destruction of plants, the disturbance of the ecosystem, and the fragile ecological environment.

[0003] Although the application of microbial fertilizers can improve the utilization rate of chemical fertilizers, reduce the extensive use of chemical fertilizers, improve soil, avoid soil salinization and pollute the environment, but due to the common problems of water shortage and fertilizer shortage in reclaimed soil in rocky ...
