This application relates to the field of slope reinforcement technology in geotechnical engineering, specifically disclosing an enzyme-induced calcium carbonate precipitation and vegetation synergy slope cover layer and its construction method. It involves constructing a coarse-particle drainage layer and laying a geotextile filter layer. A mixed-type enzyme-induced calcium carbonate precipitation process is used, where dried sword bean powder and slag are pre-mixed evenly and then laid and compacted in layers. After each layer is compacted, a urea-calcium acetate cementing solution is sprayed to cause calcium carbonate to precipitate evenly along its depth, forming a low-permeability solidified soil layer. Vegetation is then sown on the surface to form biological reinforcement. The abrupt change in permeability coefficient between the solidified soil layer and the drainage layer creates a capillary resistance effect. Combined with the reinforcement of vegetation roots and the buffering effect of raindrops from the above-ground parts, this achieves a synergistic enhancement of structural seepage prevention and ecological protection, effectively solving the problems of stability, erosion resistance, and long-term durability of steep slope cover layers.

This invention belongs to the field of biomedical technology, specifically disclosing a method for extracting and applying fermented sword bean oil. The method involves first activating Bacillus subtilis, then inoculating it onto sword bean powder for solid-state fermentation. After drying and pulverizing the fermented material, extraction is performed using an extraction solvent on a shaker and followed by filtration. The filtrate is then evaporated under vacuum to remove the solvent, yielding fermented sword bean oil. This method disrupts the cell walls of sword beans, promoting oil release and increasing the oil yield. After fermentation, the content of polyunsaturated fatty acids in the oil increases to 25.763±0.663%, with the addition of pentadecenoic acid and erucic acid, as well as DPPH and ABTS. + The free radical scavenging ability and iron ion reducing ability are significantly enhanced, resulting in improved antioxidant activity. The process conditions of this invention are mild, the process is simple, the energy consumption is low, and it is easy to scale up. The resulting oil can be used in the food, health product, and pharmaceutical industries.
