Problems solved by technology

Trace element fertilizers sold in the market are composed of single or several trace elements required by plants in the form of inorganic salts. They are generally solid powders. The disadvantage is that they cannot be completely, quickly and effectively absorbed by plants. They exist in the form of metal ions and are easily absorbed by plants. The soil is fixed, so that the trace elements cannot be played normally

Abstract

The invention discloses a liquid compound trace element fertilizer and a preparation method thereof. The fertilizer comprises the following ingredients by weight percent: 0-1.0% of citric acid, 0-1.0% of ascorbic acid (vitamin C), 0-1.0% of hydroxylamine hydrochloride, 0-1.0% of sorbitol, 0-1.0% of xylitol, 0-1.0% of mannitol, 0.46-38% of ferrous sulfate heptahydrate, 0.13-24% of manganese sulfate monohydrate, 0.18-3.3% of copper sulfate pentahydrate, 0.25-2.3% of zinc sulphate monohydrate, 0.25-4% of disodium octaborate tetrahydrate, 0.08-1.5% of ammonium molybdate, and the balance of pure water, wherein the dosage of the citric acid, the dosage of the ascorbic acid and the dosage of the hydroxylamine hydrochloride cannot be 0 at the same time, and the dosage of sorbitol, the dosage of xylitol and the dosage of mannitol cannot be 0 at the same time. According to the invention, an antioxidant prepared from one, two or more of the citric acid, ascorbic acid and hydroxylamine hydrochloride can effectively inhibit ferrous ions from being hydrolyzed into ferric ions, so that the iron ion absorption efficiency is improved, and the color of the product does not change at a high temperature; the raw material resources are rich, the production cost is low, and the equipment and production technologies are simple.

Description

technical field [0001] The invention belongs to the field of water-soluble fertilizer production, and relates to a trace element liquid water-soluble fertilizer, in particular to a liquid compound trace element fertilizer and a preparation method thereof. Background technique [0002] There is a wide area of ​​soil lacking trace elements in our country, and the effective content of trace elements in many soils is lower than the critical value necessary for plants, which seriously affects the normal growth of plants. Trace element fertilizers sold in the market are composed of single or several trace elements required by plants in the form of inorganic salts. They are generally solid powders. The disadvantage is that they cannot be completely, quickly and effectively absorbed by plants. They exist in the form of metal ions and are easily absorbed by plants. The soil is fixed, so that the trace elements cannot be played normally. With the deepening of micro-fertilizer researc...
