The apple pomace powder fermentation substrate is obtained, the apple pomace is adopted as the fermentation substrate, the apple pomace is easy to obtain and low in cost, and processing, development and utilization of apple pomace waste are achieved. Water, SRF5 strain fermentation liquor, a carbon source, a nitrogen source and inorganic potassium salt are added into the fermentation substrate, the ratio of the volume of the added water to the mass of the fermentation substrate is (2: 1)-(3: 1), and the apple pomace bacterial fertilizer is obtained through fermentation for 4-9 days in the environment with the temperature being 22-28 DEG C and the pH being natural. According to the invention, cucumber damping-off, strawberry fusarium wilt and tomato fusarium wilt can be relieved, and the growth of three crops, namely cucumber, strawberry and tomato, is promoted to a certain extent. The processing, development and utilization of the apple pomace waste are realized.
