description The invention relates to obsolete resource comprehensive utilization field, especially involves in a manufacturing method of new-type controlled release silicon-potash fertilizer, which can resolve the problem of low existing desillicification residue utilization efficiency. The manufacturing method of new-type controlled release silicon-potash fertilizer adds modifying agent, potassium carbonate or potassium hydroxide, to desillicification residue in order to manufacture silicon-potash fertilizer. Make optimum seeking of potassium carbonate, that is to say, the purity of potassium carbonate is 99%, and the adding amount of potassium carbonate of potassium hydroxide should make K2O theoretical content in silicon-potash fertilizer manufactured in the end achieve 15-30%. The invention is mainly used in manufacturing sustained release silicon-potash fertilizer with obsolete desillicification residue.
