specific Embodiment approach 1
[0021] Specific embodiment one: a kind of Trichoderma harzianum fermentation process of the present embodiment carries out according to the following steps:
[0022] 1. Selection and treatment of raw materials: choose domestic garbage or agricultural waste as raw materials, and grind them with a pulverizer after drying; Wheat bran;
[0023] Two, preparation of Trichoderma harzianum solid-state fermentation medium: add cotyledons, grape leaves, corn cobs, pineapple peels and wheat bran into the container to obtain solid-state fermentation medium for Trichoderma harzianum; said cotyledons, grape leaves, corn The mass ratio of core, pineapple peel and wheat bran is (3-6):(3-6):(3-6):(1-2):(20-41);
[0024] 3. Fermentation of Trichoderma harzianum: Get Trichoderma harzianum WY-1 bacterium liquid and add in the solid-state fermentation medium of Trichoderma harzianum prepared in step 2, the culture conditions are: initial water content 80%-100%, inoculum size 6%-10 %, 25°C-28°C f...
specific Embodiment approach 2
[0025] Embodiment 2: This embodiment is different from Embodiment 1 in that the mass ratio of the cotyledon leaves, grape leaves, corncobs, pineapple peels and wheat bran in step 2 is 4:4:4:1:27. Other steps and parameters are the same as those in the first embodiment.
specific Embodiment approach 3
[0026] Specific embodiment three: the difference between this embodiment and specific embodiment one is that step three culture conditions are: initial water content 100%, inoculum size 7%, 28 ° C for 10 days to complete the fermentation of Trichoderma harzianum. Other steps and parameters are the same as those in the first embodiment.
