Embodiment 1

[0026] The method for preparing solid compound fertilizer from traditional Chinese medicine dregs is carried out as follows:

[0027] 1. The main material of the experiment is astragalus traditional Chinese medicine residue. The auxiliary materials are dregs ash and hydrothermal synthesis degradation products of dregs. Strains: Aspergillus aculeatus Asp-3, Trichoderma harzianum Tri-5 and Bacillus subtilis Tu-100.

[0028] 2. Preparation of solid compound biological fertilizer:

[0029] (2.1) Expose the dregs of Astragalus membranaceus in the sun for two days.

[0030] (2.2) pyrolyze part of the residues of Astragalus traditional Chinese medicine after exposure to the sun to form medicinal residue ash. The pyrolysis conditions are 200°C, 40min, 4MPa.

[0031] (2.3) Part of the residues of Astragalus traditional Chinese medicine after exposure to the sun were passed through a 100-mesh sieve for ammonia explosion.

[0032] (2.3.1) Put the pulverized Astragalus medicine dregs...

Embodiment 2

[0048] (1) Pyrolyzing the dregs of Angelica sinensis to form dregs ash. The pyrolysis conditions are 200°C, 40min, 4MPa.

[0049] (2) Pulverize the angelica slag, pass through a 100-mesh sieve, and perform ammonia explosion.

[0050] (2.1) Put the pulverized angelica dregs into the ammonia explosion device, and carry out ammonia explosion under the pressure of 35, 45 and 55 atmospheres successively. The ammonia explosion temperature is 200°C, and each pressure value is maintained for 5 minutes. ; Then the pressure in the reactor is reduced to 1 atmospheric pressure to complete the explosion.

[0051] (2.2) Take 5 g of the medicinal residues blasted in step (2.1), add them to 100 mL of distilled water, and stir for 24 hours. It was separated by filtration to obtain a solid residue.

[0052] (3) Hydrothermally synthesize the dregs of traditional Chinese medicine, wherein the dregs and water are mixed and reacted in a hydrothermal synthesis reactor at a ratio of 1:2, and the c...

Embodiment 3

[0062] (1) Pyrolyzing 10 parts by weight of traditional Chinese medicine dregs to form medicinal dregs ash.

[0063] (2) Pulverize 60 parts by weight of traditional Chinese medicine dregs, pass through a 100-mesh sieve, and perform ammonia explosion.

[0064] (2.1) Put 100g of traditional Chinese medicine dregs into an ammonia explosion device, and perform ammonia explosion treatment under pressures of 35, 45, and 55 atmospheres in sequence. The ammonia explosion temperature is 350°C, and each pressure value is maintained for 5 minutes; Then the pressure in the reactor was reduced to 1 atmosphere to complete the explosion.

[0065] (2.2) Take 5 g of the medicinal residues blasted in step (2.1), add them to 100 mL of distilled water, and stir for 24 hours. It was separated by filtration to obtain a solid residue.

[0066] (3) Carry out hydrothermal synthesis of traditional Chinese medicine dregs, wherein the mixed reaction of medicinal dregs and water in a hydrothermal synthe...

Abstract

The invention relates to a method of preparing a solid composite biological fertilizer from traditional Chinese medicine dregs. The method includes a step of insolating the traditional Chinese medicine dregs, a step of subjecting a part of the traditional Chinese medicine dregs to pyrolysis to obtain traditional Chinese medicine dreg ash, a step of crushing a part of the traditional Chinese medicine dregs, sieving with a sieve having a size of 100 meshes and performing ammonia gas explosion, a step of subjecting a part of the traditional Chinese medicine dregs to degradation through a hydro-thermal synthesis manner, a step of fully stirring the traditional Chinese medicine dreg ash, a product of ammonia gas explosion, a product of the hydro-thermal synthesis and water according to a ratio of 10%, 60%, 20% and 10% and adjusting pH to 5.0, a step of performing moist heat sterilization and cooling, and a step of separately inoculating trichoderma harzianum Tri-5 and bacillus subtilis Tu-100, performing solid fermentation and air-drying to obtain the fertilizer. The fertilizer is plastic in shape and can be prepared into powder, blocks, and the like. The fertilizer increases soil nutrients and organic matter contents, improves field soil structures, increases the number of microbial population and activity of some enzymes in soil and promotes yield increasing and income increasing of crops.

Description

technical field [0001] The invention relates to a method for preparing compound biological fertilizer from traditional Chinese medicine dregs through solid fermentation. Background technique [0002] China is a country rich in resources, and the resources of traditional Chinese medicine are especially rich. At present, the active ingredients in traditional Chinese medicine basically rely on extraction, and the amount of traditional Chinese medicine dregs produced during the extraction process is quite large. For example, every time a box of Ginkgo biloba capsules is produced, 50kg of traditional Chinese medicine dregs will be produced. Most of the dregs are treated in simple and extensive ways such as incineration, stacking, and landfill. This will not only waste resources, but also cause great environmental pollution, especially serious irreversible damage to surrounding water quality, soil and air quality. Therefore it is particularly important to propose a method for p...
