Medium element water-soluble fertilizer production method

Abstract

The invention discloses a medium element water-soluble fertilizer production method, which comprises: 1) adding a water-soluble calcium fertilizer, a water-soluble magnesium fertilizer and a water-soluble boron fertilizer to water to obtain a medium element solution; 2) adding weathered coal powder to an ion exchange resin and hydrochloric acid to obtain a fulvic acid solution; 3) boiling fruit tree, and carrying out centrifugation to obtain a filtrate and waste residue; 4) decocting licorice root, honeysuckle and peppermint to obtain a medicine liquid and medicine residue; 5) uniformly mixingthe medium element solution obtained in the step 1), the fulvic acid solution obtained in the step 2), the filtrate obtained in the step 3), and the medicine liquid obtained in the step 4), and adding urea, diammonium phosphate and a fermentation bacterial liquid; and 6) adding straw and dry animal manure to plant ash, maize meal, the waste residue obtained in the step 3), and the medicine obtained in the step 4), mixing, adding the mixed liquid obtained in the step 5), fermenting, and carrying out solid-liquid separation to obtain the fertilizer. According to the present invention, with theproduction process, the nutrition of the fertilizer is substantially enriched; and by combining the mineral-derived fulvic acid and the biochemical fulvic acid, the obtained fulvic acid fertilizer canstably exist in the solid form, and can improve the antibacterial ability of the soil.

Description

technical field [0001] The invention relates to a fertilizer production method, in particular to a production method of a medium amount element water-soluble fertilizer. Background technique [0002] The nutrient elements necessary for plant growth include 17 kinds, and according to the amount of nutrient elements needed in the process of plant growth, they are divided into macroelements, medium elements, and microelements, among which macroelements are C, H, O, N, P, K, medium elements are Ca, Mg, S, trace elements are Fe, B, Mn, Cu, Zn, Mo, Cl, Ni. The existing medium-weight elements are mainly prepared by mixing calcium nitrate fertilizer, magnesium nitrate, water, etc. according to a certain ratio, which makes the nutrition of the medium-weight element water-soluble fertilizer too simple, the quality is poor, and the cost of raw materials is high. Fulvic acid is the most active part of humic acid. It has a small molecular weight, is easily soluble in water, and has good...

Problems solved by technology

[0003] The problem to be solved by the present invention is that the existing medium element water-soluble fertilizer has a single yin and yang, and the fulvic acid fertilizer uses a single biochemical fulvic acid or mineral-derived fulvic acid, and the finished product of biochemical fulvic acid is easy to absorb water and deliquescence in the air , so it is only suitable for liquid form, and it is very inconvenient to transport and use
