High tower humic acid type composite fertilizer

Abstract

The invention discloses a high tower humic acid type composite fertilizer. The high tower humic acid type composite fertilizer is prepared from the following materials in percentages by weight: 3-10 parts of urea, 10-13 parts of humic acid, 20-25 parts of ammonium humate, 15-20 parts of monoammonium phosphate, 3-7 parts of 3,4-dimethylpyrazole phosphate, 12-17 parts of potassium chloride, 12-16 parts of ammonium chloride, 1-3 parts of zinc sulfate, 1-2 parts of borax and 0.4-0.7 part of kieselguhr. The kieselguhr is added in the high tower humic acid type composite fertilizer, an effect of slowly releasing fertilizer can be achieved, furthermore, the utilization rate of the fertilizer is increased, absorption of crops is facilitated, soil is improved, the production cost is reduced, and caking of the fertilizer can be prevented; and high-quality humic acid type composite fertilizer particles can be obtained.

Description

technical field

[0001] The invention relates to a compound fertilizer, in particular to a high-tower humic acid compound fertilizer, which belongs to the technical field of chemical fertilizer production. Background technique

[0002] Humic acid is a kind of complex organic aromatic carboxylic acid macromolecule with wide application. It is mainly composed of C, H, O, N, S and other elements. Strong hydrophilic, ion exchange, complexation and adsorption capabilities; ordinary fertilizers have a short period of fertilizer effectiveness and can provide nutrients to crops in a short period of time. If they cannot be absorbed by crops in time, they will easily cause nutrient loss, which is not only wasteful, but also brings harm to the environment. Harm: Adding pretreated humic acid to ordinary fertilizers can make the fertilizer have an adsorption function, which can endow the fertilizer with a slow-release effect and the function of stimulating crop growth, achieve the effects...
