Embodiment 1

[0026] A drying-free organic-inorganic compound fertilizer and a preparation method thereof, comprising the following steps:

[0027] (1) Grinding and mixing: take 8 parts of urea, 50 parts of monoammonium phosphate, 35 parts of potassium sulfate, 40 parts of humic acid, 5 parts of medium and trace elements, 10 parts of polypeptide, 15 parts of bentonite, and 10 parts of dolomite, and grind and mix to obtain Mixed ingredients.

[0028] (2) Granulation and screening: the mixed material is added to the roller extrusion granulation equipment for granulation, the granular material and the powdery material are separated by the screening equipment, and the powdery material is returned to the granulation equipment for re-granulation. The material enters the next process.

[0029] (3) Polishing: the granular material obtained in step 2 was polished in a polishing machine for 3 hours, and at the same time, magnesium oxide was added to the polishing machine at a mass ratio of 1:0.1.

Abstract

The invention belongs to the field of organic-inorganic compound fertilizer production, and particularly relates to a drying-free organic-inorganic compound fertilizer and a preparation method thereof. The drying-free organic-inorganic compound fertilizer is prepared from 0-10 parts of urea, 10-50 parts of monoammonium phosphate, 5-35 parts of potassium sulfate, 5-40 parts of humic acid, 0-5 parts of secondary and minor elements, 0-10 parts of peptide, 0-15 parts of bentonite and 0-10 parts of dolomite. The preparation method comprises the following steps: pulverizing, mixing, carrying out extrusion granulation by a granulator, and screening to obtain the organic-inorganic compound fertilizer finished product. The organic-inorganic compound fertilizer is suitable for crops in various growth stages, and can enhance the yield and quality. The technique does not need the traditional drying process, thereby simplifying the process, reducing the equipment investment and lowering the production cost and labor cost.

Description

technical field [0001] The invention relates to the field of compound fertilizer production, in particular to a drying-free organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] Fertilization is the most effective way to increase crop yield. According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), the contribution rate of fertilizers to food crops is 30%-50%. The statistics of my country's chemical fertilizer long-term positioning test network also show that the contribution rate of chemical fertilizers to my country's grain production is 40.8%. The combined application of organic and inorganic fertilizers has always been the guideline for agricultural fertilization in my country. However, in the past 50 years, the application of chemical fertilizers has increased year by year, and correspondingly, the application of organic fertilizers has dropped sharply. According to research, in 196...
