The invention discloses an excretion fermented seedling compound fertilizer. The compound fertilizer is prepared from the following raw materials in parts by weight: 500-600 parts of livestock excretion, 120-140 parts of water hyacinth powder, 100-120 parts of castor stems, 100-120 parts of silkworm excrement, 100-120 parts of corn stalk, 80-90 parts of cottonseed cake, 40-50 parts of tobacco stems, 30-40 parts of pulverized fuel ash, 12-15 parts of river sand, 20-25 parts of calcium superphosphate, 15-20 parts of urea, 8-12 parts of potassium chloride, 1-2 parts of compound sodium nitrophenolate, 2-3 parts of copper sulfate, 6-9 parts of EM (effective microorganism) bactericide, 5-7 parts of microbial starter, 10-15 parts of soil conditioner, and a proper amount of water. The fertilizer adopts livestock excretion and the like as main raw materials through microbial fermentation, is rich in organic fertilizer, inorganic fertilizer and various nutrition, does not have toxic or side effect, does not pollute environment, can remarkably supply nutrition required by seedlings, can improve the soil structure, promote growth and development of seedlings, and improve the resilience of disease resistance, insect resistance, drought resistance, water logging resistance, cold resistance, salt alkali resistance, lodging resistance and the like.
