The scheme discloses an organic fertilizer for blueberry planting. The organic fertilizer comprises the following raw materials in parts by weight: 100-120 parts of horse manure, 150-160 parts of dry vinegar residues, 80-90 parts of ranunculus sceleratus, 70-90 parts of cow manure, 7-8 parts of sulfur powder, 50-60 parts of fir chips, 40-50 parts of laver and 3-4 parts of enzyme microorganisms. According to the scheme, by using the horse manure, the cow manure and the ranunculus sceleratus, a large quantity of nitrogen, phosphorus and potassium elements are provided for the growth of blueberries; by matching the dry vinegar residues, the fir chips and the laver, the content of the nitrogen element is further increased, and sufficient microelements are provided; by utilizing antagonism of the nitrogen, the phosphorus and the potassium, the nitrogen, phosphorus and potassium absorption of the blueberries meets growth characteristics; by utilizing the sulfur powder to regulate the pH value of the organic fertilizer, the organic fertilizer is suitable for the growth of the blueberries; and by adding the enzyme microorganisms, the content of probiotics in the organic fertilizer is increased, and soil quality is improved, so that the growth of the blueberries is promoted, and the yield is increased.
