[0037] This embodiment relates to a fertilizer additive, including the following raw materials in parts by weight: 10 parts of chitosan, 13 parts of humic acid, 20 parts of modified montmorillonite, 11 parts of sepiolite powder, 8 parts of coal gangue, fulvic acid 6 parts of potassium, 3 parts of wood ginger cotyledon, 4 parts of dodder, 4 parts of dried kudzu root branches and leaves, 2 parts of dried wild chrysanthemum, 3 parts of fly maggot powder, 40 parts of bean cake, 9 parts of seaweed powder, 7 parts of borax, and 4 parts of water retaining agent.

[0038] Wherein, the modified montmorillonite is prepared by the following method:

[0039] After montmorillonite, anionic surfactant and deionized water were stirred and reacted at 80°C for 3 hours, filtered at room temperature, the filter cake was dried and ground, and passed through a 40-80 mesh sieve to obtain organically modified montmorillonite. The anionic surfactant is ammonium lauryl sulfate, and the mass ratio of t...

Embodiment 3

[0049] This embodiment relates to a fertilizer additive, including the following raw materials in parts by weight: 6 parts of chitosan, 9 parts of humic acid, 11 parts of modified montmorillonite, 8 parts of sepiolite powder, 5 parts of coal gangue, fulvic acid Potassium 4.5 parts, wood ginger cotyledon 1.3 parts, dodder seed 2.3 parts, dried kudzu root branches and leaves 2.6 parts, dried wild chrysanthemum flower 1.1 parts, fly maggot powder 2.3 parts, bean cake 32 parts, seaweed powder 5 parts, borax 4 parts, water retaining agent 2.4 parts.

[0050] Wherein, the modified montmorillonite is prepared by the following method:

[0051] After stirring and reacting montmorillonite, anionic surfactant and deionized water at 72°C for 2.3 hours, filter at room temperature, dry and grind the filter cake, and pass through a 40-80 mesh sieve to obtain organically modified montmorillonite. The anionic surfactant is sodium cetyl alcohol isethionate, and the mass ratio of the montmorillo...

Abstract

The invention discloses a fertilizer additive. The additive comprises, by weight, 5-10 parts of chitosan, 7-13 parts of humic acid, 10-20 parts of modified montmorillonite, 6-11 parts of sepiolite powder, 3-8 parts of coal gangue, 4-6 parts of potassium fulvic acid, 1-3 parts of litsea elongate leaves, 2-4 parts of cuscuta chinensis, 2-4 parts of dried pueraria lobata branches and leaves, 1-2 parts of dried wild chrysanthemum flowers, 2-3 parts of maggot powder, 30-40 parts of soybean bran, 4-9 parts of seaweed powder, 2-7 parts of borax and 2-4 parts of water-retaining agent. According to thefertilizer additive, the environment is protected, the soil is improved, the effective components of fertilizer are increased, the slow release effect is remarkable, the utilization rate of the fertilizer is increased, and the fertilizer additive is an environment-friendly fertilizer additive suitable for various kinds of chemical fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer additive and a preparation method thereof. Background technique [0002] The production and use of chemical fertilizers have played an active role in improving fertilizer efficiency, increasing crop yields and being easy to use. However, as a result of long-term use, the negative effects brought by its inherent defects are becoming more and more prominent. For example: low fertilizer utilization rate caused by fast decomposition; pollution caused by the release of decomposition products to the atmosphere and water bodies; soil compaction, damage to the soil ecological environment for crop growth, etc. Contents of the invention [0003] The invention provides a fertilizer additive and a preparation method thereof, which solves the problems in the background technology. The fertilizer additive is a kind of fertilizer additive that protects the enviro...
