Problems solved by technology

At present, there are some reports on the fermentation of traditional Chinese medicine dregs to prepare organic fertilizers, but there are few reports on the direct use of external strains. The main reasons are: 1) The water-soluble nutrients in the dregs of traditional Chinese medicine are basically rinsed out after high-temperature and high-pressure cooking in the early stage. Low activity, lack of activated carbon and nitrogen energy sources that microorganisms can use, and microorganisms cannot grow rapidly; 2) There are certain antibacterial substances in the residue of traditional Chinese medicine, which makes it difficult for exogenous microorganisms to compost due to the competition of microorganisms after inoculation. Colonization, thus hindering the further application of traditional Chinese medicine dregs composting

Embodiment 1

[0027] Fully mix the raw materials of Artemisia annua, honeysuckle, Yuanhu, Pingbei, Poria cocos and Guizhi several kinds of traditional Chinese medicine dregs according to the dry matter weight ratio of 2:1:1:0.5:1:0.5, and use urea to adjust the carbon-nitrogen ratio to 25. Adjust the water content to 55%. As a composting raw material, carry out strip-stack aerobic composting. The dry matter weight of each stack is 3t. The length, width and height of the stack are designed to be 8m×2m×1.5m. Compost and turn over every 3-5 days. Fermentation is divided into two groups:

[0028] (1) Control group: the compost raw materials are not inoculated with microorganisms, and are directly composted. When the temperature of the compost body drops below 35°C and the water content is below 40%, organic fertilizer is obtained;

[0029] (2) Experimental group 1: Staged inoculation, that is, the inoculated bacteria content in the fermentation heating period (initial composting) was 5×10 8 ...

Embodiment 2

[0045] The raw materials of Artemisia annua, honeysuckle, Poria cocos, Moutan bark, Guizhi, peach kernel, Yuanhu, and Chuanqiong are fully mixed according to the ratio of dry matter weight 2:1:0.5:0.5:0.5:0.5:0.5:0.5. Mix, use urea to adjust the carbon-nitrogen ratio to 28, adjust the water content to 55%, carry out strip-stack aerobic composting, the dry matter weight of each pile is 3t, and the length, width and height of the pile are designed to be 8m×2m×1.5m. Strip-stack aerobic composting, turning and throwing every 3-5 days. This embodiment sets three groups of experiments:

[0046] (1) Control group: without inoculation of microorganisms, composting raw materials are used to directly carry out strip-stack aerobic composting. When the temperature of the compost body drops below 35°C and the water content is below 40%, organic fertilizer is obtained;

[0047] (2) Experimental group 3: Staged inoculation, that is, the inoculated bacteria content in the heating period (ini...

Abstract

The invention provides a method for preparing a traditional Chinese medicine residue high-activity organic fertilizer through sectional inoculation. According to the method, aerobic fermentation is carried out with traditional Chinese medicine residues as a raw material; Kaistia adipata and Pseudomonas taiwanensis are inoculated in a heating period; Streptomyces thermoviolaceus is inoculated whena composting temperature reaches 55 DEG C; and Cellulomonas uda and Pseudomonas taiwanensis are inoculated when the composting temperature drops to 45 DEG C, and fermentation is stopped when the compost temperature drops to 35 DEG C or below and a water content is 40% or below, so the organic fertilizer is obtained. According to the method, traditional Chinese medicine residue waste can be recycled, so soil pollution, water pollution and air pollution caused by the traditional Chinese medicine residue waste are reduced, development of the traditional Chinese medicine industry is promoted, andenvironmental benefits and economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a high-activity organic fertilizer from traditional Chinese medicine dregs and a preparation method thereof. Background technique [0002] my country's traditional Chinese medicine industry is developing year by year, and the solid waste of medicinal dregs produced in the production process of traditional Chinese medicine is also increasing year by year, with an annual output of up to 30 million tons. However, due to the characteristics of high humidity, odor, refractory degradation, and high wood fiber content, traditional Chinese medicine residues have many problems in subsequent utilization. Currently, the main disposal methods are incineration, landfill, and open-air stacking, which have caused great harm to the environment. pollute. [0003] Traditional Chinese medicine dregs are rich in organic matter and inorganic minerals (including nitrogen, phosphorus, p...
