preparation example Construction

[0027] Such as figure 1 As shown, the preparation method of the stalk treatment micro-ecological preparation of the embodiment of the present invention comprises the following steps:

[0028] S101, the 3 strains of lactic acid bacteria including homofermentative lactic acid bacteria and heterofermentative lactic acid bacteria obtained from isolation, identification and screening in the silage fermentation system: Lactobacillus digesta, Lactobacillus fructose and Lactobacillus brauchneri mixed culture;

[0029]S102, the culture conditions are: slant bacteria → activation (skim milk medium) → take 1 ring of bacteria and insert into liquid culture (BLB liquid medium) at 37°C, 150rpm shaker culture for 24h → 10% inoculation into anaerobic reaction Cultivate in kettle for 24 hours → standby;

[0030] S103, 3 strains of fiber-degrading bacteria from nature: Bacillus pumilus, Bacillus polymyxa and Bacillus coagulans were mixed and cultured;

[0031] S104, the culture conditions are...

Abstract

The invention discloses a straw treatment microecological preparation and a preparation method thereof. The straw treatment microecological preparation comprises digestive lactobacillus, lactobacillus fructivorans, lactobacillus buchneri, bacillus pumilus, bacillus polymyxa and bacillus coagulans. The preparation method comprises the following steps of carrying out mixed culture on three lactic acid bacteria: the digestive lactobacillus, the lactobacillus fructivorans and the lactobacillus buchneri which are separated, identified and screened from a silage fermentation system and contain homofermentative lactic bacteria and heterofermentative lactic bacteria; carrying out the mixing culture on three fibrolytic bacteria: the bacillus pumilus, the bacillus polymyxa and the bacillus coagulans which are from the nature; mixing two mixtures into a composite product, wherein the microbial storage inoculation amount of every ton of straws is 1 L. The straw treatment microecological preparation disclosed by the invention can be used for enhancing the silage quality and the aerobic stability and reducing the loss of weight in a fermentation process by reducing pH and protein degradation rate and is very significant to animal husbandry production by reducing the decomposing speed of a silage after the silage is fed by opening a cellar.

Description

technical field [0001] The invention belongs to the technical field of straw micro-ecological preparations, in particular to a straw-processing micro-ecological preparation and a preparation method thereof. Background technique [0002] my country is a big agricultural country and also a big straw producer. At present, the annual production of crop straw in my country is about 650 million tons, of which corn straw accounts for 36.7%. These straws have not been well utilized. The amount of straw used as grass-fed livestock feed is about 200 million tons, accounting for about 30% of the total straw. %, a large amount of straw is burned in the field, which not only wastes a lot of resources but also causes serious air pollution. Although the party and the government have always attached great importance to the utilization rate of straw resources as feed, there are still many problems in the direct use of straw as feed: (1) Poor palatability, long digestion time, and lignin, as ...
