The invention provides a degradation agent containing an aldehyde ketoreductase mutant and a folium cortex eucommiae extract and application of the degradation agent. According to the invention, aldoketoreductase derived from Methylocapsa sp. Is mutated, a mutant library is constructed, trichoderma reesei is taken as an expression host, and the aldoketoreductase mutant AkrH with significantly improved vomitoxin degradation effect is obtained through screening. Compared with the original gene, the degradation level of the mutant AkrH on vomitoxin is improved by about 3 times. The degradation agent is prepared by compounding spray-dried powder prepared from recombinant bacteria containing the aldoketoreductase mutant AkrH, the folium cortex eucommiae extract, montmorillonite powder and other adsorbents, and the like, and can degrade vomitoxin in feed raw materials, and the average degradation rate of the vomitoxin reaches 95% or above; the bacillus amyloliquefaciens has a good application ...
