The invention discloses a fertilizer for pears. The fertilizer is prepared from an organic fertilizer, an inorganic fertilizer and additives. The organic fertilizer is prepared from, by weight, 40-60parts of mung bean straw, 20-30 parts of cow dung, 10-20 parts of wormcast, 20-30 parts of biogas residues, 10-20 parts of oil residues, 15-25 parts of river mud, 30-50 parts of plant ash and 2-4 parts of enzyme bacteria. The additives include weathered coal, zeolite and carbonized reed residues. By matching of substances in an appropriate ratio, balanced nutrients can be provided for pear tree growth, soil bulk density, air permeability, physiochemical properties, enzyme activity and bacterial community can be improved, nutrient absorption of the pear trees is promoted, problems of soil fertilizer accumulation and soil hardening are ameliorated, and pear yield is increased.
