Abstract

The present invention discloses a biochar-seed gel for vegetation rehabilitation in saline-alkali soil, a preparation method thereof, and an application thereof and belongs to the technical field of vegetation rehabilitation. The biochar-seed gel of the present invention includes a water-retaining hydrogel, effective nutrient components, and a structural maintenance agent, wherein the water-retaining hydrogel is polyacrylamide; the effective nutrient components comprise Bacillus subtilis inoculant, brassinolide, chitosan oligosaccharide, polyaspartic acid, and compound fertilizer; and the structural maintenance agent comprises biochar, clay, chitosan, and Gleditsia sinensis powder. In the present invention, the biochar-seed gel forms a microenvironment on the soil surface, mitigating stress caused by high-salinity soil conditions. The gel exhibits strong water-retention capacity, effectively maintaining moisture to support seed and seedling growth while alleviating water deficiency resulting from soil compaction.
