Embodiment 1

[0009] Example 1: 1 gram per serving

[0010] A high-efficiency straw decomposing compound bacterial group, the bacterial group is composed of the following strains by weight percentage:

[0011] 1.4 grams of Phanerochaete chrysosporium, 1.4 grams of Lentinus edodes, 0.7 grams of Trichoderma harzianum, 0.7 grams of Trichoderma viride, 0.7 grams of Trichoderma corning, 0.7 grams of Aspergillus niger, 0.73 grams of Bacillus subtilis, 0.73 grams of Feed Bacillus, giant 0.73 grams of Bacillus, 0.14 grams of Candida, 0.14 grams of alcoholic yeast, 0.07 grams of edible yeast, 0.14 grams of brown spherical nitrogen-fixing bacteria, and 0.35 grams of high-temperature actinomycetes. After the strains in the above weight ratio are mixed, 1 g of them is mixed evenly with 1000 g of pulverized straw, and then fermented.

Embodiment 2

[0012] Embodiment 2: Each serving is 1 catty

[0013] A high-efficiency straw decomposing compound bacterial group, the bacterial group is composed of the following strains by weight percentage:

[0014] 2.6 kg of Phanerochaete chrysosporium, 2.6 catties of shiitake mushrooms, 1.3 catties of Trichoderma harzianum, 1.3 kg of Trichoderma viride, 1.3 catties of Trichoderma korningen, 1.3 catties of Aspergillus niger, 1.2 catties of Bacillus subtilis, 1.24 catties of feed Bacillus, huge 1.24 catties of Bacillus, 0.26 catties of Candida, 0.26 catties of alcoholic yeast, 0.13 catties of edible yeast, 0.26 catties of brown spherical nitrogen-fixing bacteria, and 0.65 catties of high-temperature actinomycetes. After the strains in the above weight ratio are mixed, 4 catties of them are mixed with 8000 catties of crushed straw and then fermented.

Embodiment 3

[0015] Example 3: Each serving is 1 kg

[0016] A high-efficiency straw decomposing compound bacterial group, the bacterial group is composed of the following strains by weight percentage:

[0017] Phanerochaete chrysosporium 2.0 catties, Lentinus edodes 2.0 kg, Trichoderma harzianum 1.0 kg, Trichoderma viride 1.0 kg, Trichoderma korningen 0.8 kg, Aspergillus niger 1.2 kg, Bacillus subtilis 0.85 kg, Bacillus 1.15 kg, huge 0.95 kg of bacillus, 0.2 kg of candida, 0.25 kg of alcoholic yeast, 0.1 kg of edible yeast, 0.19 kg of brown spherical nitrogen-fixing bacteria, and 0.45 kg of high-temperature actinomycetes. After the strains in the above weight ratio are mixed, 3 kg of them are mixed evenly with 1000 kg of pulverized straw and then fermented.

Abstract

The invention relates to a biotechnology dealing agricultural discard stem with an highly effective stem decomposing composite bacterial, which dissolves the problem of single species of applying microbiological bacterial, weak breaking up, low total degradability rate of cellulose, long developmental cycle. The composite bacterial comprises the following parts: yellow archespore wool bacterium leather bacterial, mushroom bacterial, haci trichoderma, green trichoderma, coninic trichoderma, aspergillus niger, bacillus subtilis, feed bacillus, bacillus megaterium, candida, distillery yeast, food-yeast, brown sphere azotobacter, thermoactinomyces, and so on. The composite bacterial can overall degrade lignin, cellulose, hemicellulose and other organic material in the stem, has a more than 80% degrading rate, a 10-15 days short cycle, keeps a long time for providing a solid bacteria.

Description

technical field [0001] The invention relates to the biological technology of using microorganisms to treat agricultural waste straws, in particular to a high-efficiency straw decomposing compound bacterial group. Background technique [0002] Straw includes rice straw, wheat straw, corn straw, bean straw, sorghum straw, etc., which are leftovers of food crops. In the rural areas of our country, most of the crop straws are burned directly, which not only causes serious environmental pollution, but also causes a waste of resources. In recent years, people have gradually realized that crop straw contains a large amount of cellulose, hemicellulose, lignin and other organic substances, which account for about 60% of the dry weight of straw. People use microbial fermentation technology to degrade straw. On the one hand, it can be used as feed for ruminants, and on the other hand, it can be used as organic fertilizer, which is an effective way to improve soil and increase soil org...
