The invention relates to a seeding medium made of 
vinasse methane-
sludge and a preparation method thereof, not only solving the problem of environment 
contamination caused by 
vinasse methane-
sludge, but also effectively utilizing 
vinasse methane-
sludge. The seeding medium comprises fresh sludge containing 90 percent of water after methane generated from vinasse in a methane tank, accessories, ferment strain I and ferment strain II, wherein the accessories comprise grass 
peat, 
vermiculite and 
perlite; the ferment strain I comprises 
saccharomycetes, 
lactobacillus, high-temperature actinomycetes and bacillus; and the ferment strain II comprises 
photosynthetic bacteria, 
lactobacillus, bacillus, 
saccharomycetes, actinomycetes and terrestrial 
cyanobacteria. The preparation method comprises the following steps of preparing fresh sludge, dehydrating, adding the ferment strain I for 
fermentation, adding the ferment strain II for secondary 
fermentation, 
air drying, adding accessories, crushing, screening and packing. The vinasse methane-sludge contains 40 to 50 percent of 
organic matter and 4.3 percent of available 
nitrogen (N), 
phosphorus (P) and kalium (K). The seeding medium made of vinasse methane-sludge has better hydrophilicity, and seeding can be carried out after loading the dry seeding medium and spraying water, thus saving both labor and time.
