Embodiment 1

[0024] A method for utilizing agricultural waste, characterized in that it comprises the following steps:

[0025] a. Pick a ring of bacteria from the original starting strain, inoculate it into the seed medium, and culture it on a shaker at 36°C-37°C, 150-170rpm, for 16-20 hours until OD600=0.7-0.9 , stop culturing, as seed solution;

[0026] b. Inoculate the seed solution with 1%-5% inoculum in the liquid expansion LB medium (bacteria of the genus Pseudomonas stutzeri, bacteria of the genus Bacillus), PYG medium (bacteria of the genus Lactic acid bacteria), 36°C-37°C Under the temperature, 150-170rpm, shaker culture 20-28 hours. The fermentation culture liquid of various bacterial strains is mixed evenly according to the ratio of 1:1, and is used as the fermentation strain liquid of agricultural waste;

[0027] c. Inoculate the agricultural waste fermentation seed liquid in b into agricultural waste with a water content of 25%-40% with an inoculation amount of 1%-5%, mix e...

Embodiment 2

[0031] On the basis of Example 1, the bacterial strain seed culture medium in step a contains the glucose of 0.5%-1.0%, the lactose of 0.3%-0.5%, the sodium chloride of 0.3%-0.5%, the sodium chloride of 0.5%- 1.0% peptone and 0.5%-1.0% yeast extract; the LB medium described in step b contains 0.3%-0.5% sodium chloride, 0.3%-0.5% peptone and 0.5%-1.0% yeast extract; The PYG medium contains 0.5%-1.0% glucose, 0.3%-0.5% lactose, 0.3%-0.5% sodium acetate, 0.5%-1.0% peptone and 0.5%-1.0% yeast extract.

Embodiment 3

[0033] On the basis of embodiment one or embodiment two, the bacterial classification described in its step a is Pseudomonas stutzeri bacterium 1 strain, Bacillus subtilis bacterium 2 strains and Lactobacillus bacterium 1 strain.

Abstract

The invention relates to the agricultural field, in particular to an agricultural waste utilization method. The technical scheme is as follows: the agricultural waste utilization method comprises thesteps as follows: a, a cyclic bacterium is selected from initial strains for production of a nutrient solution serving as a seed solution; b, an agricultural waste fermented strain solution is produced; c, agricultural waste with the moisture content being 25%-40% is inoculated with the agricultural waste fermented strain solution in the step b in the inoculation size of 1%-5%, the obtained material is placed in a closed container after being mixed uniformly, the material is compacted so that no air exists in the material, the material is sealed and fermented at 20-38 DEG C for 48-72 h, culture is stopped, and the obtained material is placed in a shady and cool place at the room temperature; d, storage is performed; e, the fermented agricultural waste can be used as feed for cattle, pigs,tilapia and the like. The invention aims to provide a technology for converting and producing the agricultural waste into biological feed on the basis of a microbial fermentation technology, so that the overall economic benefits of the breeding industry can be improved and environmental pollution can be reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for utilizing agricultural waste. Background technique [0002] With the vigorous development of animal husbandry in various places, livestock and poultry excrement has become one of the main sources of pollution of the environment. A farm of 100,000 laying hens produces about 11 tons of chicken manure and 35 tons of sewage every day. In addition, there is a considerable amount of feathers and feed. On March 20, 2001, the State Environmental Protection Administration officially issued (Order No. 9) "Administrative Measures on the Prevention and Control of Pollution from Livestock and Poultry Breeding", which clearly stipulates that "the prevention and control of pollution from livestock and poultry breeding shall be given priority in comprehensive utilization, resourceful, harmless and Principles of Quantification". Therefore, transforming poultry farm waste materials into a...
