Embodiment 1
[0047] The present embodiment provides a kind of preparation method of Trichoderma biological granule, specifically comprises the following steps:
[0048] 1. Plate strains: inoculate Trichoderma aculeatus ZJSX5003 on a PDA medium plate in a 28°C incubator; invert for 2 to 3 days.
[0049] PDA medium: 200g potatoes cut into 1cm 3 Small pieces, boiled on low heat for 30 minutes, filtered through 4 layers of gauze to retain the juice; add 20 grams of glucose, 20 grams of agar powder, distilled water to 1 liter, and autoclave at 121 ° C for 30 minutes.
[0050] 2. Preparation of secondary strains: Take 200 grams of potatoes, 20 grams of glucose, and 1 liter of water to prepare a secondary fermentation culture solution, adjust the pH value to 6-8, and distribute 100 milliliters in 250 milliliter triangular flasks. Sterilize at 121°C for 30 minutes, insert plate strains, shaker speed is 180 rpm, fermentation temperature is 28°C, fermentation time is 3 days, and a large number of d...
