Embodiment 1

[0025] A preparation method of corn stalk and bagasse mixed fermented feed, the steps are as follows:

[0026] 1) Grinding dry corn stalks and bagasse into particles of 0.2-0.5 cm and mixing them. The weight of corn stalk powder in the mixed material accounts for 75% and bagasse 25%;

[0027] 2) Ammonizing the mixture of corn stalks and bagasse by spraying evenly concentrated ammonia water with a concentration of 25% by weight on the mixture and reacting for 6 weeks at normal temperature to obtain a fermentation substrate;

[0028] 3) Prepare No. 1 mixed fermentation broth, and No. Ⅰ mixed fermentation broth is made of Aspergillus niger ( Aspergillus niger , WB-4757), white rot fungus ( Phanerochaete chrysosporium ), Bacillus subtilis ( Bacillus subtilis subsp. Subtilis , N1025), Trichoderma korningen ( Trichoderma koningii , 201-9), the culture medium of Aspergillus niger, white rot fungus, Bacillus subtilis and Trichoderma koningen all contained in every 1000ml: potat...

Embodiment 2

[0034] A preparation method of corn stalk and bagasse mixed fermented feed, the steps are as follows:

[0035] 1) Grinding dry corn stalks and bagasse into particles of 0.2-0.5 cm and then mixing them. The weight of corn stalk powder in the mixed material accounts for 80%, and the bagasse accounts for 20%;

[0036] 2) Ammonizing the mixture of corn stalks and bagasse by spraying evenly concentrated ammonia water with a concentration of 25% by weight on the mixture and reacting for 7 weeks at normal temperature to obtain a fermentation substrate;

[0037] 3) Prepare No. 1 mixed fermentation broth, the preparation method is the same as in Example 1, add No. 1 mixed fermentation broth and sterile water to the fermentation substrate and mix evenly, the fermentation substrate, fermentation broth and sterile water The mass percentages are: 65%, 10%, 25%, the first step of fermentation is carried out at room temperature for 3 days, the material is turned once a day, and the humidity ...

Abstract

The invention provides a preparation method for a cornstalk-bagasse mixed fermented feed. According to the invention, dried cornstalk and bagasse are used as raw materials; ammoniated treatment is carried out at first so as to remove lignin, hemicellulose and cellulose in cornstalk and bagasse; a mixed fermentation bacteria solution I and a mixed fermentation bacteria solution II are sprayed on the mixed material of cornstalk and bagasse for two-step fermentation so as to fully degrade lignin, hemicellulose and cellulose in the mixed material and increase the content of mycoprotein, thereby increasing the content of crude protein and other nutrients in a final product of the feed. The invention has the following advantages: common bacterial strains for feeds are combined in the method, and the bacterial strains used in the method do not generate an obvious antagonistic effect and are not pathogenic bacterial systems; collective fermentation of the mixed bacterial systems enables the utilization efficiency of cornstalk and bagasse resources and the content of nutrients to be effectively increased; equipment and process flow are simple, convenient to operate and easy to popularize and apply, and the preparation method in the invention provides an effective channel for environmental protection and high efficiency reutilization of resources and promotes the progress of resource utilization technology of crop straws.

Description

technical field [0001] The invention relates to agricultural environmental protection technology, in particular to a method for preparing corn stalk and bagasse mixed fermented feed. Background technique [0002] my country is a big animal husbandry country, and there is a great demand for livestock feed. Since the 1980s, the animal husbandry industry has maintained a high-speed growth, which has caused a continuous increase in the gap in feed resources. The annual gap is about 20 million tons, and a large amount of feed needs to be imported. my country has a large population, and the "competition between humans and animals for food" has not been effectively resolved. The progress of China's economy has also increased the demand for meat products, posing a more serious challenge to the supply of grain feed, and the supply of energy feed has been relatively short. In recent years, food crops have become an important raw material for the development of biofuels, further causin...
