The invention provides a preparation method of loropetalum chinense extract and application of the loropetalum chinense extract in preparation of products for wound healing, and relates to the technical field of traditional Chinese medicine extraction. The preparation method comprises the following steps: mixing a loropetalum chinense raw material, water and composite biological bacteria, and carrying out enzymolysis to obtain an enzymolysis product; the composite biological bacterium is a mixture of phanerochaete chrysosporium and streptomyces griseus; carrying out gradient alcohol extraction on the enzymolysis product, merging alcohol extracts, extracting with petroleum ether, and concentrating an organic phase to obtain a component 1; the component 1 is adsorbed by macroporous adsorption resin, the resin is washed with deionized water and then eluted with an eluent, 5-35 min eluent is collected, combined and dried, and the component 1 is obtained. The elution phase is a mixture of cyclohexane, ethyl acetate and acetonitrile. The loropetalum chinense extract is prepared through a specific preparation method, and the wound healing effect is remarkably improved.

The invention relates to application of trichoderma harzianum to prevention and treatment of potato black scurf and scab. The trichoderma harzianum with the preservation number of CGMCC (China General Microbiological Culture Collection Center) No.40017 can well inhibit rhizoctonia solani, so that the effect of preventing and treating potato black scurf is achieved; trichoderma harzianum with the preservation number of CGMCC No.40017 can also inhibit streptomycete, such as streptomyces scabies, streptomyces scabies and streptomyces griseus, so that the effect of preventing and treating potato scab is achieved, the strain or the microbial agent containing the strain is applied to the planting process of potatoes, potato black scurf and scab can be effectively prevented and treated, and the effect of preventing and treating potato scab is achieved. The method has important significance in agricultural production.

This invention discloses a compound microbial fertilizer for improving soil acidification and its preparation method, relating to the field of soil improvement technology. It comprises the following components: microbial inoculant, modified nano-selenium complex, quicklime, biochar, humic acid, decomposed organic matter, and trehalose. The microbial inoculant contains *Bacillus belye*, *Lactobacillus plantarum*, and *Streptomyces griseus*. The modified nano-selenium complex is obtained by loading nano-selenium particles onto chitosan modified with ferulic acid. The fertilizer prepared by this invention achieves synergistic effects of soil improvement and increased rice yield through a triple mechanism of chemical neutralization, biological acid stabilization, and nano-inactivation, and also possesses selenium-enriching properties, demonstrating significant market potential.
