The invention discloses trichoderma biocontrol recombinant engineering bacteria for efficiently expressing chitinase and Beta-1,3-glucanase genes derived from trichoderma as well as application thereof. The recombinant bacterial strain is the recombinant engineering bacteria which are acquired by converting trichoderma viride LTR-2 with plant disease biocontrol function from a T-DNA derived carrier which is mediated by agrobacterium and contains the chitinase code gene chi42 derived from the trichoderma and the Beta-1,3-glucanase coding gene glultr-2. The recombinant bacteria can stably express the chitinase code gene chi42 and the Beta-1,3-glucanase coding gene glultr-2 in a PDA culture medium; and a pot plant experiment indicates that the recombinant engineering bacteria have more effective prevention and control effects to vegetable botrytis and wheat sharp eyespot compared with glutamicum LTR-2.

The invention discloses disinfectant used for edible fungus breeding. The disinfectant comprises, by volume, 4 mL-8 mL of hydrogen oxide, 14 mL-19 mL of carbolic acid, 8 mL-15 mL of methylphenol solutions, 0.5 mL-1.1 mL of 8-hydroxyquinoline, 2 mL-5 mL of sodium stearate, 1 mL-4 mL of light calcium carbonate and 45 mL-55 mL of deionized water. All the components are mixed for certain time at normal temperature and normal pressure, and the disinfectant is obtained through subpackage and plastic package. Through the mode, the disinfectant used for the edible fungus breeding is broad in spectrum and has high capacity for killing trichoderma, blue mould, mucor and other sundry funguses which are severe in harm in the production process of edible funguses, meanwhile, the sundry funguses are prevented from growing again, no other effect exists, and the growth of the edible funguses is not affected.
