Abstract
Способ получения гуминовых удобрений, при котором смешивают торф с водным раствором гидрата окиси калия или натрия, полученную смесь нагревают и выдерживают при повышенной температуре, непрерывно перемешивая, а образовавшийся раствор гумата калия или натрия отделяют от реакционной массы, отличающейся тем, что смешивают торф с раствором гидрата окиси калия или натрия концентрации 3,5-4,5 г/л в весовом соотношении 1:2,5-1:10, перемешивают образовавшуюся смесь в течение 2-3 ч при температуре 70-90°С, а затем в полученный раствор гумата калия или натрия добавляют 15-25% раствор сернокислого цинка, нагревают полученную смесь до температуры 80-100°С, выдерживают при указанной температуре в течение 10-14 ч, отделяют фульфатно-цинковый раствор, а образовавшийся осадок гумата цинка осаждают на фильтре, досушивают в сушилке и мелят на мельнице до необходимой фракции.A method of producing humic fertilizers, in which peat is mixed with an aqueous solution of potassium hydroxide or sodium hydrate, the resulting mixture is heated and maintained at an elevated temperature, continuously stirring, and the resulting solution of potassium or sodium humate is separated from the reaction mass, characterized in that peat is mixed with a solution potassium oxide or sodium hydrate of a concentration of 3.5-4.5 g / l in a weight ratio of 1: 2.5-1: 10, mix the resulting mixture for 2-3 hours at a temperature of 70-90 ° C, and then into the resulting potassium or sodium humate solution I add a 15-25% zinc sulfate solution, heat the mixture to a temperature of 80-100 ° C, maintain it at the indicated temperature for 10-14 hours, separate the zinc sulfate solution, and the precipitate of zinc humate precipitated on the filter, dried in a dryer and grind in the mill to the desired fraction.
