Problems solved by technology

[0003] However, in order to further improve the application effect of humic acid-containing water-soluble fertilizers, existing manufacturers usually add a variety of plant growth hormones to the fertilizer components, and plant growth hormones are a low-toxicity pesticide. Environmental hazards are still controversial in academia
In addition, the colloid bundles containing humic acid water-soluble fertilizers are usually unstable, and precipitation and stratification will occur after long-term storage, which will affect the use effect of water-soluble fertilizers

Abstract

The invention provides a water soluble fertilizer containing high-concentration humic acid. The water soluble fertilizer comprises, by weight, 15-25 parts of a water soluble humic acid salt, 18-25 parts of urea, 9-15 parts of dipotassium hydrogen phosphate, 8-13 parts of potassium acetate, 0.5-2 parts of borax, 0.1-10 parts of polyglutamic acid, 1-5 parts of rhamnolipid, 5-10 parts of a hydroxymethyl cellulose aqueous solution and 30-40 parts of water. The water soluble fertilizer has humic acid content greater than or equal to 150g / L. The invention also provides a preparation method of the water soluble fertilizer containing high-concentration humic acid. The preparation method comprises the following steps of 1, carrying out heating stirring of the water soluble humic acid salt and water to obtain a humic acid salt solution, 2, adding dipotassium hydrogen phosphate, potassium acetate, borax, polyglutamic acid, rhamnolipid and urea into the humic acid salt solution, and carrying out heating stirring to obtain a mixed solution, and 3, carrying out emulsification of the hydroxymethyl cellulose aqueous solution and the mixed solution to obtain the water soluble fertilizer containing high-concentration humic acid. The water soluble fertilizer has obvious fertilizer efficiency, is environmentally friendly, stable and uniform and has a wide application range.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a water-soluble fertilizer containing high-concentration humic acid and a preparation method thereof. Background technique [0002] Due to the special molecular structure of humic acid, the fertilizer containing humic acid can improve the soil and stimulate the growth of crops. Compared with the humic acid solid fertilizer, the water-soluble fertilizer containing humic acid has obvious advantages of fast fertilizer efficiency, balanced nutrition, water saving and fertilizer saving, Easy to use and other advantages. [0003] However, in order to further improve the application effect of humic acid-containing water-soluble fertilizers, existing manufacturers usually add a variety of plant growth hormones to the fertilizer components, and plant growth hormones are a low-toxicity pesticide. Environmental hazards are still controversial in academic circles. In addit...
