Abstract: The present invention discloses a complexing agent for promoting decomposition of loquat leaf litter, which belongs to the technical field of plant science. According to the present invention, the mixed solution of Pseudomonas solution, lignin peroxidase, and leucine aminopeptidase solution is applied to the loquat leaf litter, and after in-situ decomposition for four months, the mass loss rate and the decomposition constant of the loquat leaf litter are significantly increased, thereby effectively promoting the decomposition of the loquat leaf litter. The present invention first proposes that the decomposition of the loquat leaf litter is influenced by externally applying a combination agent of enzyme and bacterial solution, which is simple in operation, and promotes the decomposition of the loquat leaf litter while increasing the speed of returning organic matters to soil, thereby improving soil fertility.

Abstract: The present disclosure relates to the technical field of biomedicine, in particular to use of advanced platelet-rich fibrin (A-PRF) in preparing a medicament for the treatment of diabetic foot ulcer. The A-PRF provided by the present disclosure has a loose reticular fibrin structure, can be rich in more platelets and leukocytes, can release a plurality of growth factors and cytokines more persistently, and is more beneficial to tissue regeneration and wound repair. The medicament prepared from the A-PRF shortens the healing period of the diabetic foot ulcer, improves the healing rate, and has an excellent treatment effect and high safety.
