the preparation process of the fermented feed comprises the following steps:
activating: heating seawater with a preset weight to 28-35 ℃, and then sequentially adding dry yeast and zymophyte into the seawater for activation for 2 hours to obtain an activation solution;
mixing materials: sequentially putting the leafy vegetables, scallop edges, rainbow, sargassum thunbergii, oyster shells and multi-dimensional elements with preset weight into a sterilized stirring tank, uniformly stirring, and placing the mixture in an anaerobic culture room with the room temperature of 28-35 ℃ for later use;
③ fermentation: putting the activating solution into a stirring tank, uniformly stirring the activating solution and the mixture, tightly sealing the stirring tank after uniformly mixing, and fermenting the stirring tank in a space with room temperature of 30 ℃ for 24-30 hours;
fourthly, the sea mud is put into the fermented material in the third step and is evenly stirred, and then the material is put into a grinding machine for curing treatment, so that the fermented feed is obtained.
4. The method for feeding sea cucumber seedlings by mixing the granulated feed and the fermented feed according to claim 1, which is characterized in that: the pellet feed comprises, by weight, 35-45 parts of leafy vegetables, 40-45 parts of sea mud, 3-7 parts of scallop edges, 3-7 parts of rainbow sea, 8-12 parts of sargassum thunbergii, 2-5 parts of oyster shells, 2-4 parts of multi-vitamin elements, 3-5 parts of dry yeast and 170 parts of seawater 130-doped materials;
the preparation process of the pellet feed comprises the following steps of mixing and stirring the leafy vegetables, the sea mud, the scallop edges, the rainbow, the sargassum thunbergii, the oyster shells, the multi-vitamin elements, the dry yeast and the seawater uniformly, then putting the mixture into a granulator to prepare pellets, and airing the pellets for 48 hours at the indoor temperature of 25-30 ℃ to obtain the pellet feed.
