The invention provides a fermentation method of animal wastes, which comprises the following steps:
(1) adding straw, urea and plateau strain into animal waste to obtain mixture,
(2) stirring the mixture, and adjusting the water content of the mixture to be 50-60 wt% and the temperature to be 20-25 ℃;

In the invention, the plateau strain can be any strain capable of being used for fermenting animal excrement under the high and cold conditions of plateaus, and specifically, the plateau strain comprises 30-40 wt% of bacillus subtilis, 12-18 wt% of bacillus mucilaginosus, 18-22 wt% of actinomycetes, 0.5-2 wt% of thermophilic bacteria, 1-3 wt% of aerobic bacteria, 10-15 wt% of mould, 4-6 wt% of lactobacillus plantarum, 0.5-2 wt% of saccharomyces cerevisiae, 2-4 wt% of protease bacteria and 4-6 wt% of inhibiting pathogenic bacteria, wherein the total weight of the plateau strain is 100%; preferably, the plateau strain comprises 35 wt% of bacillus subtilis, 15 wt% of bacillus mucilaginosus, 20.5 wt% of actinomycetes, 1 wt% of thermophilic bacteria, 2 wt% of aerobic bacteria, 12.5 wt% of mould, 5 wt% of lactobacillus plantarum, 1 wt% of saccharomyces cerevisiae, 3 wt% of protease bacteria and 5 wt% of pathogenic bacteria inhibiting bacteria, wherein the total weight of the plateau strain is 100%; the animal manure can be one or more of cow manure, sheep manure, horse manure, pig manure, poultry manure and human manure; however, since the number of cattle and sheep is large in the alpine region of the plateau, the animal manure is preferably selected from cattle manure and/or sheep manure. More preferably, the animal manure has a sand content of less than or equal to 3 wt% in order to increase the fertilizer efficiency of the fermented manure product. The straws can be straws of any plants, and most of crops planted in the highland severe cold area are highland barley due to special regional characteristics, so the straws are preferably highland barley straws.
The water content of the mixture can be measured by conventional means, and the commonly used judgment method in the invention is to grasp a material by hand, see the watermark but not drip water, and scatter the ground.
The addition amount of the animal waste, the straw, the urea and the plateau strain can be added by a person skilled in the art according to professional knowledge, preferably, after the addition, the carbon-nitrogen ratio of the mixture is 25-30:1, and the carbon-nitrogen ratio of the mixture can be 25:1, 26:1, 27:1, 28:1, 29:1, 30:1 and any value in the range included by the numerical values. And the mixture obtained after mixing is neutral. Neutral generally means pH 7, however, it is difficult to adjust pH to exactly 7 in the actual operation process, and if pH is around 7, people skilled in the art will generally consider it to be neutral, so we can generally ensure that pH is around 7, and the pH range is 6.5-7.5 in the actual operation process.
More preferably, based on the animal manure, the addition amount of the urea is 0.05-0.2 wt%, the addition amount of the plateau strain is 0.1-0.2 wt%, and the addition amount of the straw is 0.2-0.6 wt%.

The water added in the process is hot water; the temperature of the water is preferably 40-50 ℃.
In the present invention, the laid insulation layer may be an insulation layer commonly used by those skilled in the art. Furthermore, when the insulation is applied, it is preferable to keep the mixture in air with the outside, and there are various methods for keeping the mixture in air with the outside, such as: a plurality of vent holes are arranged on the heat preservation layer, or only one vent hole is arranged in the middle of the heat preservation layer; during fermentation, the temperature of the mixture needs to be detected at any time, and when the temperature of the mixture is higher than 35 ℃, the heat-insulating layer is removed.
In order to prevent nutrient loss due to excessive temperature, the temperature of the mixture should be controlled to be lower than 60 ℃ during the fermentation process, and the temperature of the mixture in the invention can be controlled to be lower than 60 ℃ by adopting the conventional means, such as controlling the temperature of the whole fermentation tank or increasing the air circulation inside the fermentation tank. The temperature is preferably controlled below 60 ℃ by stirring the mixture. And when the temperature of the mixture is higher than 60 ℃, the mixture is stirred mechanically or manually, and the method is simple and convenient. The whole fermentation time is 20-30 days.
The steps further include: stacking the fermentation product. The stacking time can be controlled by the person skilled in the art according to his or her expert knowledge, preferably 5 to 7 days. During the stacking process, the mixture is turned over once a day, and is fully fermented by stirring.
