Problems solved by technology

Due to the planting of various crops in rural areas, a large amount of straw is produced every year, and the utilization rate is low. In the end, it is often burned in the open air, which not only wastes resources, but also causes environmental pollution.
On the other hand, China's animal husbandry industry is now facing a shortage of feed. The annual feed gap is about 20 million tons. It also imports about 1.6 million tons of fishmeal every year. At present, the price of imported fishmeal has skyrocketed, exceeding 10,000 yuan per ton. Poor quality will become the main factor restricting the sustainable development of my country's animal husbandry

Embodiment 1

[0031] The invention discloses a method for preparing straw feed, which converts straw into high-quality feed for poultry and livestock. The specific implementation is as follows:

[0032] Crush the straw to 1-3mm. 3 days before the start of fermentation, prepare Cha's liquid culture medium, cultivate Aspergillus niger and Aspergillus oryzae bacterium liquid, prepare Bacillus liquid medium 2 days before starting fermentation, cultivate Bacillus subtilis bacterium liquid, culture Aspergillus niger, rice Aspergillus and Bacillus subtilis bacterial liquids are mixed at a ratio of 1:1:1 to make a mixed bacterial liquid. Mix the straw powder, the above-mentioned mixed bacterial solution and water according to the weight ratio of 70:5:25, stir evenly, turn over the pile once a day, and ferment for 4 days. The rate is about 30%. Yeast extract powder peptone glucose medium was prepared 2 days before adding the mixed yeast solution, and the mixed yeast solution was cultivated. The m...

Embodiment 2

[0034] The invention discloses a method for preparing straw feed, which converts straw into high-quality feed for poultry and livestock. The specific implementation is as follows:

[0035] Crush the straw to 1-3mm. 3 days before the start of fermentation, prepare Cha's liquid culture medium, cultivate Aspergillus niger and Aspergillus oryzae bacterium liquid, prepare Bacillus liquid medium 2 days before starting fermentation, cultivate Bacillus subtilis bacterium liquid, culture Aspergillus niger, rice Aspergillus and Bacillus subtilis bacterial liquids are mixed at a ratio of 1:1:1 to make a mixed bacterial liquid. Mix the straw powder, the above-mentioned mixed bacterial liquid and water according to the weight ratio of 60:5:35, stir evenly, turn over the pile twice a day, and ferment for 4 days. The rate is about 40%. Yeast extract powder peptone glucose medium was prepared 2 days before adding the mixed yeast solution, and the mixed yeast solution was cultivated. The mi...

Abstract

The invention provides a straw feed and a preparation method thereof, relating to the technical field of environmental protection, in particular to a straw fermentation fungicide and preparation thereof. The method comprises two steps of aerobic fermentation and one step of anaerobic fermentation to prepare the straw feed, and specifically comprises the steps of crushing straws; preparing mixed bacteria liquid of aerobic degraded cellulose so as to conduct the aerobic fermentation on straw powder; preparing mixed fermentation bacteria liquid to conduct the aerobic fermentation on the straw powder; preparing lactic acid bacteria liquid so as to conduct the anaerobic fermentation on the straw powder; and drying the fermented straw feed and pelletizing. The method improves the utilization ratio of lignin, cellulose and hemicellulose in straws, crude protein contents in a fermented product are increased, and the straw is converted into a super poultry feed.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for preparing straw fermented feed. Background technique [0002] Straw contains cellulose, hemicellulose, lignin, organic matter, nitrogen, phosphorus, potassium and trace elements, etc., and is rich in nutrients. Due to the planting of various crops in rural areas every year, a large amount of straw is produced, and the utilization rate is low. Finally, it is often burned in the open air, which not only wastes resources, but also causes environmental pollution. On the other hand, China's animal husbandry industry is now facing a shortage of feed. The annual feed gap is about 20 million tons. It also imports about 1.6 million tons of fishmeal every year. At present, the price of imported fishmeal has skyrocketed, exceeding 10,000 yuan per ton. Poor quality will become the main factor restricting the sustainable development of my country's animal husband...
