The invention relates to a composite microbe fertilizer. The composite microbe fertilizer is prepared by 25-35 wt% of vegetable garden soil, 5-10 wt% of active functional bacteria, 5-15 wt% of mineral powder, 25-30 wt% of an organic fertilizer, 15-20 wt% of an inorganic composite fertilizer, and water; wherein the sum of the components is 100%. The active functional bacteria comprise lactic acid bacteria, bacillus subtilis, Bacillus megaterium, trichoderma, aspergillus niger, monascus, Trichoderma harzianum, aspergillus aculeatus and yeast, the mineral powder is a mixture of one or more of peat, zeolite, vermiculite, montmorillonite, calcium carbonate and expanded perlite, fineness of the mineral powder is less than or equal to 200 meshes, the organic fertilizer contains decomposed manure, a rapeseed cake fertilizer, and straw, and the weight ratio of the manure to the rapeseed cake fertilizer to straw is 5.5-7.5:2.5-3.5:0.5-1.5.
