Liquid water-soluble color-changing fertilizer containing amino acid and trace element and dilution control method of fertilizer

Abstract

The invention relates to a liquid water-soluble color-changing fertilizer containing an amino acid and a trace element and a dilution control method of the fertilizer; an amino acid-containing organic matter, a trace element fertilizer, an acid-base regulator, an acid-base buffer agent, a color-changing agent and water are added into a reaction kettle according to a certain mass ratio, and are stirred and dissolved completely in the reaction kettle to obtain the liquid water-soluble color-changing fertilizer containing the amino acid and the trace element; a certain mass of the liquid water-soluble color-changing fertilizer containing the amino acid and the trace element is taken and put in a container, and water is gradually added into the container to dilute the fertilizer to make the color changed, namely, the dilution concentration is achieved. By using a principle that the color-changing agent shows different colors along with the change of the concentration of H<+>, the purpose of controlling the dilution concentration of the liquid water-soluble fertilizer is achieved by color changing.

Description

technical field [0001] The invention relates to a liquid water-soluble color-changing fertilizer containing amino acid trace elements and a method for controlling the dilution of the fertilizer. Background technique [0002] At present, after 10 years of development, water-soluble fertilizers have already occupied a certain place in the market. However, due to the scattered land in China, crops cannot be produced on a large scale. Many places have begun to install drip irrigation, sprinkler irrigation and other equipment, and water-soluble fertilizers have been used. It must be diluted with water before use, so the effect of water-soluble fertilizer is greatly affected by the dilution factor. A small dilution factor may cause burnt seedlings or leaves, resulting in reduced production; a large dilution factor may have no obvious effect, and thus also cause a reduction in production. [0003] At present, the control of the dilution ratio of water-soluble fertilizers in my c...

Problems solved by technology

For example, in some rural areas, due to the lack of measuring tools or the inconvenience of carrying the measuring tools, operators often rely on experience to control the amount of water added, which is easy to cause the problem of inaccurate dilution concentration and affect the normal function of fertilizers.
