Preparation method of composite microbial inoculum for producing silage from rotten vegetable leaves and straw

Abstract

The invention relates to a preparation method of composite microbial inoculum for producing silage from rotten vegetable leaves and straw. The method comprises the following steps of (1) uniformly mixing milk with brown sugar in proportion so as to obtain a solution A; (2) adding lactic acid bacteria mixed liquor to the solution A, performing uniform mixing to obtain mixed liquor, and adding inorganic salts to the mixed liquor in a manner of adding 1 part of the inorganic salts to each liter of the mixed liquor so as to obtain a solution B; (3) adding corn flour to the solution B, and performing uniform stirring so as to obtain raw materials of which the moisture content is 30-45%; and (4) loading the raw materials into anaerobic bags, performing fermentation under the condition of 28-36 DEG C for 3-5 days, when the pH value reaches 3.8-4.1 and lactic acid bacteria reach 2-20 billion cfu / g, performing drying under an aseptic condition, performing crushing, and performing bagging so as to obtain the microbial inoculum special for the silage. The preparation method disclosed by the invention is simple in technology and low in cost; and through the obtained composite microbial inoculum, the fermentation time of the silage is shortened, and the fermentation efficiency is improved.

Description

technical field [0001] The invention relates to the field of silage production, in particular to a preparation method of a compound bacterial agent used for producing silage from tail vegetables and straw. Background technique [0002] In recent years, the vegetable industry in Gansu has developed rapidly, and it has become one of the five major commercial vegetable bases in the country's "West-to-East Vegetable Transfer" and "North-to-South Vegetable Transport" and a key production area for exporting vegetables in the northwest inland. Especially in the main vegetable producing areas such as the Yellow River Irrigation Area, Yuzhong Basin, Hexi Corridor, and Huicheng Basin, taking advantage of the climate characteristics of cool summer temperature, sufficient sunshine, and large temperature difference between day and night on the Northwest Plateau, the vegetables produced have a longer harvesting and marketing period. It makes up for the gap in the supply of summer vegetabl...

Problems solved by technology

[0003] The patent with the publication number CN103518957A uses tail vegetables and wheat straw to produce silage, and the added strain is single, which cannot effectively reduce the acidity in a short period of time, and the quality of the feed is difficult to control

At present, there is still a lack of commercial bacteria agents for the production of silage from tail vegetables and straw
