Abstract

The invention discloses a novel amino acid water-soluble fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer production. The novel amino acid water-soluble fertilizer comprises the following components in parts by weight: 800 to 1200 parts of desalinated liquid clear liquid, 150 to 300 parts of urea, 50 to 150 parts of monopotassium phosphate, 200 to 400 parts of potassium sulfate, 3 to 5 parts of magnesium sulfate, 3 to 5 parts of zinc sulfate, 3 to 5 parts of boric acid, 3 to 5 to 8 parts of EDTA iron sodium salt, 1 to 3 parts of manganese sulfate, 1 to 3 parts of copper sulfate, 1 to 3 parts of calcium nitrate and 1 to 3 parts of ammonium molybdate. The preparation method comprises the following steps: mixing the urea, the monopotassium phosphate, the potassium sulfate and the desalinated liquid clear liquid uniformly to obtain a mixed material 1; adding the magnesium sulfate, the zinc sulfate, the boric acid, the EDTA iron sodium salt, the magnesium sulfate, the copper sulfate, the calcium nitrate and the ammonium molybdate gradually into the mixed material 1 to obtain a base material; performing drying treatment on the base material and spraying powder to obtain the novel amino acid water-soluble fertilizer powder. According to the novel amino acid water-soluble fertilizer and the preparation method thereof, the problem about utilization of monosodium glutamate fermentation waste liquid is solved; meanwhile, the qualified fully-soluble amino acid fertilizer is produced, and the problems of high pollution and high energy consumption in the conventional fertilizer production are solved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a novel amino acid water-soluble fertilizer and a preparation method thereof. Background technique [0002] The production process of monosodium glutamate will produce a large amount of waste liquid, which is very difficult to deal with, which has caused great pressure on environmental protection. MSG waste liquid contains a lot of bacterial protein and ammonium sulfate; bacterial protein can be used as animal feed. The monosodium glutamate desalted liquid after the bacterial protein is separated contains high ammonium sulfate, and also contains a large amount of organic matter, amino acids and other nutrients, which is a very good fertilizer raw material. [0003] Many monosodium glutamate production enterprises use spray granulation to produce fertilizers from waste liquid. The production process not only consumes a lot of energy, but also seriously p...
