Embodiment 1

[0018] A kind of method utilizing dregs of traditional Chinese medicine to produce organic fertilizer, the steps are as follows:

[0019] 1) First, dry the traditional Chinese medicine dregs and crush them into particles with a particle size of 1-5mm, and crush the corncobs into particles with a particle size of 2-5mm, and the clay is attapulgite powder, and pass through a 30-mesh sieve after grinding;

[0020] 2) Mix 80kg of traditional Chinese medicine dregs, 7kg of corn cob and 10kg of clay, then add 2kg of No. Ⅰ mixed fermentation broth with 3 kg of wood chips as the carrier and mix evenly. 1:1 mass ratio of cultured mixed fermentation bacteria liquid, after starting composting and fermentation, turn the compost once a day, add water to maintain the humidity of the material and make the moisture content of the fermentation material to 45%, after the temperature rises to 60-70°C, Maintain for 3 days to obtain fermented material;

[0021] 3) When the temperature of the abov...

Abstract

The invention relates to a method for producing an organic fertilizer from traditional Chinese medicine dregs, which comprises the following steps: by taking traditional Chinese medicine dregs, corn cobs and clay as raw materials and wood dust as a fermentative bacterium solution carrier, pulverizing, mixing, fermenting, drying, and screening, wherein a mixed fermentative bacterium I used for primary fermentation is a mixed fermentative bacterium solution which is obtained by culturing Bacillus subtilis and Bacillus stearothermophilus according to a mass ratio of 1:1; and a mixed fermentative bacterium II used for secondary fermentation is a mixed fermentative bacterium solution which is obtained by culturing Bacillus lateraporus, Bacillus megaterium and Trichoderma koningii according to a mass ratio of 1:1:1. The invention has the following advantages: (1) the traditional Chinese medicine dregs are fully utilized, and the wastes are changed into valuable substances; (2) the addition of attapulgite powder can promote the fermentation process, and is beneficial to the shaping and granulation of fermentation finished products; (3) through the fermentation treatment, pathogens in the raw materials are eliminated; and (4) the organic content in the obtained organic fertilizer is higher than 55%, the NKP content exceeds 4%, the soil property can be effectively improved, and the crop yield can be increased.

Description

technical field [0001] The invention relates to the preparation of organic fertilizers, in particular to a method for producing organic fertilizers by utilizing traditional Chinese medicine dregs. Background technique [0002] With the progress of the Chinese medicine pharmaceutical industry, the dosage forms of Chinese herbal medicine products are constantly enriched, and the development of active ingredient extraction technology produces a lot of Chinese herbal medicine leftovers. According to the survey, the annual discharge of traditional Chinese medicine dregs in the country has reached 30 million tons, and the annual discharge of traditional Chinese medicine dregs in Tianjin has reached 400,000 tons. The organic matter and incompletely extracted medicinal ingredients in traditional Chinese medicine dregs are about 90%, of which the lignocellulose content is about 80%. At present, these leftovers are mostly discarded as garbage. [0003] The treatment of traditional Ch...
