Abstract

The invention relates to the technical field of water culture fertilizer, and specially relates to a preparation method of a water culture fertilizer for hydroponic crops. According to the preparation method, in a coating machine, an alginate water solution is used to carry out a coating treatment, then a crosslinking agent water solution is adopted to carry out a wrapping treatment to prepare dry particles; then an epiboly agent is added to carry out an epiboly treatment; after the alginate water solution reacts with the crosslinking agent water solution and the epiboly agent; the sustained-release period is prolonged, the water culture environment is improved; furthermore, as the sustained-release period is prolonged continuously, the alginate macromolecules are degraded into micromolecules, the fertilizer in the wrapped layer is completely released; after the sodium citrate in fertilizer particles is released, the alginate gel can be dissolved quickly, the alginate gel is decomposed, and the quality of water culture nutrient solution is improved.

Description

technical field

[0001] The invention relates to the technical field of hydroponic fertilizers, in particular to a method for preparing hydroponic fertilizers for hydroponic crops. Background technique

[0002] Soilless cultivation is a crop cultivation technique that does not use natural soil as a substrate. It is to cultivate crops directly in a nutrient solution in a certain device, or to cultivate crops on a cultivation bed filled with inactive solid substrates and nutrient solutions, because during the cultivation process , does not use traditional soil as a substrate, so it is called soilless cultivation. Hydroponics is a type of soilless cultivation in which crops are grown in a nutrient solution.

[0003] In the traditional hydroponic process, the requirements for hydroponic fertilizer are relatively strict. In the process of nutrient solution preparation, the requirements for water quality are high, so that the water medicine can avoid being polluted by heavy metals...
