Problems solved by technology

[0002] At present, although the existing soil-improving fertilizers can play a role in improving the soil, these fertilizers have poor air permeability and fermentation and decomposition capabilities, and cannot effectively decompose various naturally occurring fibers and some artificially synthesized chemical substances. Not long-lasting, crops absorb less nutrients from fertilizers, and fertilizer use efficiency is low

Embodiment 1

[0027] This example relates to an organic fertilizer, including the following raw materials in parts by weight: 12 parts of animal manure, 7 parts of fish pond sludge, 16 parts of sesame straw, 10 parts of shell powder, 15 parts of kelp residue, 3 parts of traditional Chinese medicine residue, modified 9 parts of montmorillonite, 4 parts of boric acid, 2 parts of binder, 1 part of fermentation decomposition curing agent, 11 parts of urea, 4 parts of potassium oxide, 2 parts of phosphorus pentoxide, 1 part of lignosulfonate.

[0028] Wherein, the preparation method of the modified montmorillonite is as follows: after montmorillonite, anionic surfactant and deionized water were stirred and reacted at 70° C. for 2 hours, filtered at room temperature, the filter cake was dried and ground, and passed through 40 ~80-mesh sieve to obtain organically modified montmorillonite, the mass ratio of montmorillonite, anionic surfactant and deionized water is 1:0.2:13.

Abstract

The invention discloses organic fertilizer. The organic fertilizer is prepared from raw materials in parts by weight as follows: 12-25 parts of animal dung, 7-13 parts of fish pond sludge, 16-28 partsof sesame straw, 10-20 parts of shell powder, 15-30 parts of kelp residues, 3-8 parts of traditional Chinese medicine residues, 9-17 parts of modified montmorillonite, 4-7 parts of boric acid, 2-5 parts of a binding agent, 1-3 parts of a fermentation and decomposition curing agent, 11-23 parts of urea, 4-9 parts of potassium oxide, 2-4 parts of phosphorus pentoxide and 1-3 parts of lignosulfonate. The organic fertilizer is strong in breathability and fermentation and decomposition capability and high in nutrient content, has functions of fertilizer conservation and water retention, and has lasting fertilizer efficiency and high fertilizer utilization ratio.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an organic fertilizer and a preparation method thereof. Background technique [0002] At present, although the existing soil-improving fertilizers can play a role in improving the soil, these fertilizers have poor air permeability and fermentation and decomposition capabilities, and cannot effectively decompose various naturally occurring fibers and some artificially synthesized chemical substances. It cannot last long, the crops absorb less nutrients from the fertilizer, and the fertilizer utilization rate is low. Contents of the invention [0003] The present invention provides an organic fertilizer and a preparation method thereof, which solves the problems in the above-mentioned background technology. The organic fertilizer has strong air permeability, fermentation and decomposition ability, high nutrient content, fertilizer and water retention, long-lasting...
