Abstract

The invention relates to a production method of a discoloring anti-counterfeit water-soluble microelement fertilizer. The fertilizer is obtained by mixing microelements, a pH adjuster, a discoloring agent and the like in a closed environment. Under the condition that the natural color of the fertilizer is not influenced, according to the theory that the discoloring agent is discolored by regulating the pH value, the fertilizer dissolves and discolors after being thrown in water, so that the purpose of preventing counterfeits is achieved, and the problem of fading is solved.

Description

technical field [0001] The invention relates to a preparation method of trace element water-soluble fertilizer with color-changing and anti-counterfeiting effects. Background technique [0002] In order to make the fertilizer anti-counterfeit, it has become the main practice in the fertilizer manufacturing industry to make the fertilizer have a specific color. At present, water-soluble fertilizers with a large number of elements are mainly dyed by adding dyes. Because the amount of dyes is strictly limited, it is difficult to achieve uniform dyeing, and there are many cases of color fading after dyeing. Hands are full of colors, which makes people feel disgusted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for producing color-changing anti-counterfeit trace element water-soluble fertilizer, which utilizes [0004] The principle of acid and alkali changing the color of the color changing agent, aft...
