To ascertain the influence of mushroom residues substitution of chemical fertilizer on rice growth and soil nutrient content,field experiment of formula fertilization(CK),formula fertilization reduction 1+mushroom residues(JZ-1),formula fertilization reduction 2+mushroom residues(JZ-2),formula fertilization reduction 3+mushroom residues(JZ-3)was conducted.Results showed that compared with CK,reduce chemical fertilizer dosage and increase mushroom residues would not affect the absorption and content of nitrogen,phosphorus and potassium,have no significant effect on soil physicochemical properties,but increase spikelet number per panicle and grain production significantly.
