The invention discloses a production method for high-concentration defluorinate nitro nitrogen phosphorus and potassium compound fertilizer, which is based on the conventional process route of nitric acid phosphatic manure production, an acid-insoluble substance deep desorbing procedure is added in an acid-insoluble substance precipitation separation procedure so as to radically separate the acid-insoluble substance; a mother liquor defluorinating procedure is added between calcium nitrate filtration and mother liquor neutralization, by adding potassium nitrate into mother liquor, fluosilicic acid ions in mother liquor is reacted with potassium ion to generate potassium fluorosilicate product, after defluorinating reaction, potassium fluorosilicate is separated from slurry through filtering and separating, and ammonia neutralization, evaporation, pelletization, drying and cooling treatment are performed on defluorinated mother liquor by adding potassium nitrate and ammonium nitrate, namely, high-concentration nitro nitrogen phosphorus and potassium compound fertilizer is obtained. In the invention, mid low grade phosphate rock is used for preparing compound fertilizer, namely fluorine resource is recycled, and by-product potassium fluorosilicate is obtained, pollutions to the environment are reduced, the obtained product has an excellent performance, chlorine is not contained, the application range is broad, the probability of caking is low, and the market competitiveness is strong.
