The invention discloses an improved soil solidification functional control release blended fertilizer, which is prepared from the following raw materials in percentage by weight: 5 to 13 percent of urea, 11.7 to 30.3 percent of crop stalk modified film coating controlled release urea, 20.2 to 32.5 percent of diammonium phosphate, 5 to 11 percent of potassium chloride, 11.7 to 25.5 percent of modified epoxy resin film coating controlled release potassium chloride, 2 to 5 percent of calcium oxide, 5 to 8 percent of charcoal, 9.3 to 10.5 percent of kieselguhr, 0.2 to 0.4 percent of gamma-glutamicacid and 0.1 percent of paraffin. The functional control release blended fertilizer has the advantages that the influence on the activity of nitrogen and phosphorus caused by basic raw materials in the fertilizer can be completely avoided; meanwhile, the replacement and the leaching loss of soil salt-based ions can be effectively reduced, so that the soil acidification problem in South China, northern orchards and greenhouse planting regions can be solved.
