Zusammenfassung:	The invention relates to a production method of a glyphosate solution, which comprises the following reaction processes of: generating iminodiacetic acid calcium salt through the reaction of ammonia water, chloroactic acid and lime, then changing into iminodiacetic acid hydrochloride by adding hydrochloric acid, then adding orthophosphorous acid and formaldehyde to produce N-(phosphonomethyl) iminodiacetic acid, oxidizing the N-(phosphonomethyl) iminodiacetic acid through concentrated sulphuric acid to obtain a glyphosate mixed liquid, adding a glyphosate primary drug or glyphosate wet crystals and introducing liquid ammonia/the ammonia water to prepare a 30-percent glyphosate ammonium salt solution. The production method has simple reaction processes, and no other chemical substances harmful to crops are added, thus the obtained glyphosate is nontoxic and harmless, also contains a phosphate fertilizer and a nitrogenous fertilizer, has very good control effect when applied to several common weeds with univers
