[0008] The livestock manure includes one or more of pig manure, cow manure, sheep manure, chicken manure, duck manure, and silkworm manure.

[0009] The composite microbial agent is prepared by mixing anaerobic bacteria, aerobic bacteria, actinomycetes, lactic acid bacteria and yeast in a mass ratio of 1:3:2:2:2; the number of anaerobic bacteria is 20 billion / gram, the number of aerobic bacteria is 1 billion / gram, the number of actinomycetes is 500 million / gram, the number of lactic acid bacteria is 8 billion / gram, and the number of yeast is 10 billion / gram.

[0010] The anaerobic bacteria are one or both of anaerobic digestion bacteria and anaerobic cellulose decomposition bacteria; the aerobic bacteria are one or both of Escherichia and Bacillus subtilis; and the actinomycetes are one or both of Streptomyces and Saccharomyces.

[0066] Implementation process temperature change and result detection:

[0067] The temperature changes, total organic matter (TOM), total phosphorus (TP), total potassium (TK), total nitrogen (TN) and cellulose and lignin indicators in the finished compost were measured.

[0068] The pile temperature was measured using a 0-100°C mercury thermometer to read the average temperature at different locations in the middle of the pile at 9:00 a.m. every day; cellulose and lignin were determined using high performance liquid chromatography-ultraviolet detection; TC and TN were determined using an element analyzer (VarioMacroCube, Elementer, Germany), and TP and TK were determined using an inductively coupled plasma mass spectrometer (NEXION300, PerkinEImer, USA).

[0069] Temperature changes such as Figure 1As shown, the average maximum temperature of the three embodiments entered the high temperature period of 70°C on the 4th day, dropped below 70°C on the 16th day, and dropped below 60°C on the 22nd day, which had very good effects on the maturity and sterilization effects; while the average maximum temperature of the three comparative examples entered the high temperature period of 60°C on the 4th day, and the highest temperature only reached 68°C on the 10th day, never reaching 70°C, and then began to be lower than 60°C on the 17th day, and began to be lower than 50°C on the 25th day; the ambient temperature was always below 20°C during the test, indicating that the composting temperature was not greatly affected by the ambient temperature, and the temperature of the embodiment in the warming period and the high temperature period was higher than that of the comparative example, indicating that the microbial agent can colonize and reproduce rapidly in the mixture of medicinal residues, and can promote warming more than the comparative example, and the high temperature blocks and mushroom-shaped fungi that appear in the high temperature period and the mature period of the embodiment are about two days earlier than those of the comparative example, which can effectively improve the fermentation and decomposition effect, effectively kill pathogens and insect eggs, etc., and improve the quality of compost.

[0070] The changes of total organic matter, nutrients and lignin in each embodiment and comparative example before and after composting are shown in Table 1:

[0071] As can be seen from Table 1, the total carbon TC (w / %) of the embodiments and the comparative examples before and after composting was slightly reduced, the total nitrogen TN (w / %) was increased, and the increase in the embodiments of this scheme was slightly larger, the total phosphorus TP (w / %) was increased, and the increase in the embodiments of this scheme was slightly larger, and the total potassium TK (w / %) was increased, and the increase in the embodiments of this scheme was slightly larger.

[0072] As can be seen from Table 1, the initial average content of cellulose (w / %) in each embodiment of the present scheme during composting is 33.55w / %, and the average content at the end of composting is 6.12w / %, which is a decrease of 81.76%; the initial average content of cellulose in each comparative example during composting is 41.60w / %, and the average content at the end of composting is 30.12w / %, which is a decrease of 27.60%; it can be seen that the decomposition range of cellulose in the present scheme is much greater than that of the comparative example; the initial average content of lignin (w / %) in each embodiment of the present scheme during composting is 7.57w / %, and the average content at the end of composting is 3.17w / %, which is a decrease of 56.12%; the initial average content of lignin in each comparative example during composting is 11.63w / %, and the average content at the end of composting is 9.87w / %, which is a decrease of 15.13%; it can be seen that the decomposition range of lignin in the present scheme is much greater than that of the comparative example.
