Problems solved by technology

[0002] Chemical fertilizers can provide the nutrients needed for the growth of crops and plants. With sufficient nutrients and quick results, they have become the first choice of fertilizers for farmers. However, after years of practice, the disadvantages of chemical fertilizers have gradually been exposed.
In the soil with excessive application of chemical fertilizers, the content of inorganic matter increases sharply, organic matter weakens, trace elements are unbalanced, crop diseases and insect pests become more and more serious, and a large amount of chemical fertilizers are applied, which will easily cause the nitrate content in vegetables to exceed the standard, and the combination of nitrite and amine substances The formed N-nitroso compound is a strong carcinogen, which is not conducive to human health

Embodiment 1

[0022] 10% to 30% by weight of coal gangue and 30% to 60% of coal slime are respectively subjected to Raymond milling, and the conditions of the Raymond milling are at a pressure of 1667 to 2744Pa and a temperature of 20 to 30°C for 3 hours per hour. ~5 tons, the obtained mixture and 10%~30% of fly ash are mixed again; then add 5%~20% of poultry manure and 1%~10% of livestock manure to the above mixture, and then put it into the mixer for 20 Stir evenly for 5-10 minutes per rpm; then the product obtained in the above steps is granulated by roller under 4-8 atmospheric pressure with an air volume of 16156-30993 m / h; High-temperature disinfection at 800°C, and then cooled to 10-20°C by two fans at 8288 rpm.

[0023] It is also possible to carry out the 2.8-4.2 grain size finished product sieve classification to the above-mentioned product, and measure the finished product package with 50kg.

[0024] This embodiment is prepared from the following raw materials by weight percenta...

Embodiment 2

[0027] The preparation method of embodiment 2 is the same as that of embodiment 1, except that it is prepared from the following raw materials in weight percentage: 20% coal gangue and 60% coal slime, 10% fly ash, poultry manure 5%, livestock manure 5%. Obtain organic matter (nitrogen and potassium element mixing) 40% through assay (same as embodiment 1); Humic acid 35%; Active bacteria 080 million, be specifically EM functional bacteria; Trace element is boron, iron, silicon, molybdenum.

[0028] In this embodiment, poultry manure is selected from duck manure, and livestock manure is selected from sheep's manure. In this embodiment, due to the large content of coal elements, the content of organic matter and humic acid is relatively large, so the nutrient content of the soil is relatively high, and the effective rate of the fertilizer is relatively high.

Embodiment 3

[0030] The preparation method of embodiment 3 is the same as that of embodiment 1, except that it is prepared from the following raw materials in weight percentage: 30% coal gangue and 40% coal slime, 15% fly ash, poultry manure 5%, livestock manure 10%. Obtain organic matter (nitrogen and phosphorus element mixing) 30% through assay (with embodiment 1); Humic acid 30%; Active bacteria 100 million, be specifically EM functional bacteria and spoilage bacteria; Trace element is boron, iron, silicon.

[0031] In this embodiment, poultry manure is selected from goose manure, and livestock manure is selected from sheep and cattle manure. This embodiment is a preferred embodiment, the ratio of coal elements and feces is appropriate, the content of organic matter, humic acid and active bacteria is high, and the action rate of fertilizer is the largest.

[0032] The assay method in above embodiment is:

[0033] 1. Determination of organic matter content (using GB18877---2002)

Abstract

The invention provides an organic fertilizer and a preparation method thereof. The organic fertilizer comprises the following raw materials in percentage by weight: 10% to 30% of coal gangue, 30% to 60% of coal slime, 10% to 30% of fly ash, 5% to 20% of livestock manure, and 1% to 10% of animal waste. The organic fertilizer provided by the invention has a good fertilizing effect and can improve the structure of land to a certain extent.

Description

technical field [0001] The invention relates to an organic fertilizer, especially a fertilizer which can improve the soil structure; the invention also relates to a preparation method of the organic fertilizer. Background technique [0002] Chemical fertilizers can provide the nutrients needed for the growth of crops and plants. With sufficient nutrients and quick effects, they have become the first choice of fertilizers for farmers. However, after years of practice, the disadvantages of chemical fertilizers have gradually been exposed. In the soil with excessive application of chemical fertilizers, the content of inorganic matter increases sharply, organic matter weakens, trace elements are unbalanced, crop diseases and insect pests become more and more serious, and a large amount of chemical fertilizers are applied, which will easily cause the nitrate content in vegetables to exceed the standard, and the combination of nitrite and amine substances The formed N-nitroso comp...
