The present invention discloses a rapeseed meal enzyme-linked micro-ecological preparation and a solid fermentation method of rapeseed meal. The preparation comprises ingredients: xylanase, beta-glucanase, galactosidase, beta-mannanase, cellulase, phytase, acid protease, neutral protease, papain, alkaline protease, amylase, lactic acid bacteria, bacillus, yeasts, starch and polysaccharides. The preparation is prepared by mixing the various enzyme preparations with the fermentation micro-organisms, reduces the use of an acidifier, reduces production costs, and at the same time enhances decomposition and detoxification effects of the preparation. A produced fermented rapeseed meal feed product is rich in 3-15% of lactic acid; glucosinolate is reduced by 80% or more and toxic effects on livestock and poultry are significantly reduced; crude proteins are increased by 1-2% and a consumption of non-protein materials is ensured; a small peptide content is increased to 15-25% and utilization of animals for feed proteins is effectively improved; and bitter substances in the rapeseed meal are effectively removed and a tannin degradation rate is 60% or more.
