Problems solved by technology

However, the content of humic acid in peat, lignite or weathered coal is low. In order to ensure that the content of main nutrients in the inorganic compound fertilizer remains unchanged, the content of humic acid needs to be controlled. Therefore, the content of humic acid in the inorganic compound fertilizer , that is, the organic matter content is not high, and it cannot significantly improve the soil and fertilizer efficiency; moreover, humic acid has poor water solubility, and after simple mixing with inorganic compound fertilizer, it can only be used as base fertilizer by random sowing or hole application. Applied into the soil, it cannot be used as a water-soluble fertilizer, so it can be fertilized by dripping, spraying or watering

Embodiment 1

[0035] Preparation of humic acid binder

[0036] The particle size of humic acid weathered coal (humic acid content is 40%), bentonite, straw lignin and potassium hydroxide is crushed to 80 mesh, 150 mesh, 80 mesh and 60 mesh respectively, according to humic acid weathered coal 50% , 10% of bentonite, 20% of straw lignin and 20% of potassium hydroxide are mixed in the reactor, the total weight of humic acid weathered coal, bentonite, straw lignin and potassium hydroxide is 100kg, and then Add 250kg of water to the reactor, close the reactor, keep the pressure in the reactor at 0.15kp, raise the temperature of the reactor to 80°C, stir the material at a speed of 100rmp during the heating process, keep stirring for 1h after the temperature reaches 80°C, then stop stirring, and the material Stand at a constant temperature of 80°C for 10 hours, open the reaction kettle, put the material into the sedimentation tank for 8 hours, take the supernatant, spray dry, and crush the product...

Embodiment 2

[0039] Preparation of fully water-soluble humic acid multifunctional compound fertilizer

[0040] The humic acid binder prepared in Example 1 was pulverized into a 100-mesh fine powder, and the basic fertilizer was pulverized into an 80-mesh fine powder, and put into a blender according to the consumption of 534kg of basic fertilizer and 466kg of humic acid binder and mixed evenly, After granulation, drying, cooling and screening on a disc granulator, it is automatically bagged and packaged to make fully water-soluble humic acid multifunctional compound fertilizer. Among them, the basic fertilizer contains 173kg of urea, 164kg of monoammonium phosphate, and 197kg of potassium chloride.

[0041] The percentages by weight of N, P, and K nutrients in the fully water-soluble humic acid multifunctional compound fertilizer gained in the present embodiment are respectively 10%, 10% and 10%, the total nutrient content is about 30%, and the humic acid content is about 30%. 32%, and th...

Abstract

The invention provides a multifunctional full water-soluble humic acid compound fertilizer, which is prepared from the following raw materials in percentage by weight: 70% to 90% of base fertilizer and 10% to 30% of humic acid binder. The multifunctional full water-soluble humic acid compound fertilizer is prepared by uniformly blending the base fertilizer and the humic acid binder according to a ratio after being crushed, granulating on a disc granulator, drying, cooling and screening and then automatically packaging into a bag. The base fertilizer comprises a nitrogen phosphorus potassium fertilizer, the humic acid binder is prepared by taking bentonite, humic acid weathering coal, lignin and inorganic base as raw materials in proportion, putting into a reactor after being crushed, and purifying after a high temperature reaction. The humic acid binder is prepared from the following raw materials in percentage by weight: 10 to 20% of bentonite, 50 to 60% of humic acid weathering coal, 10 to 20% of lignin, and 10 to 20% of inorganic base. The full water-soluble humic acid compound fertilizer is formed by mixing and granulating the humic acid binder and the inorganic compound fertilizer, and is a multi-purpose multifunctional compound fertilizer capable of improving the soil while hole-applying, pouring, drip-applying, spraying and sowing.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fully water-soluble humic acid multifunctional compound fertilizer. Background technique [0002] With the continuous development of our modern agricultural construction, the demand for high-quality and efficient fertilizers that can increase production and income and achieve environmental protection is increasing. However, at present, the domestic supply is mainly inorganic fertilizers such as nitrogen, phosphorus, and potassium. Long-term use of inorganic fertilizers will damage the soil aggregate structure, easily cause soil compaction, and soil hardening. As a result, the more chemical fertilizers are used, the more the output is. Low grotesques. Therefore, more and more attention is paid to organic-inorganic compound fertilizers. Adding organic fertilizers can improve soil structure, prevent soil compaction, and increase production. [0003] Humic acid is...
