Multifunctional full water-soluble humic acid compound fertilizer

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.

[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...
