Maize straw quick ensiling complex microorganism additive and use method thereof

Abstract

The invention relates to a maize straw quick ensiling complex microorganism additive which comprises the following components of aspergillus oryzaze, plant lactic acid bacteria, and a mixture of plant lactic acid bacteria and lactic streptococci. A use method comprises the following steps : 1) smashing green maize straws to prepare maize straw powder; 2) adding an organic carrier which is formed by mixing maize powder and bran into the smashed maize straw powder, uniformly mixing the materials until the water content rate of the mixture keeps 65-70%, and taking the mixture as an ensiling raw material; and 3) uniformly spraying a complex microorganicm additive in the ensiling raw material, and simultaneously, spraying an inorganic additive formed by mixing salt, urea and water into the ensiling raw material wherein the compacted density is 550-650kg/m<3>, the fermentation temperature is 25-30 DEG C, and the closed compacted anaerobic fermentation is carried out for twenty-four to twenty-six days. The maize straw quick ensiling complex microorganism additive and the use method have the advantages that the use effect of the ensiling microorganism additive is improved, the quality of ensiled feed is improved, the time for ensiling the maize straws is shortened, and the ensiling production effect can be improved.

Description

technical field [0001] The invention relates to a microbial fermentation additive with stalks as a substrate, in particular to a preparation and application method of a corn stalk rapid silage compound microbial additive. Background technique [0002] Silage is to keep the green straw isolated from the air for airtight storage, so that anaerobic bacteria ferment to produce organic acid, which then creates an acidic environment in the silage, inhibits the growth of other aerobic microorganisms, and achieves the purpose of preserving the nutrition of the green straw. If silage can be properly preserved, it can meet the feed demand throughout the year and reduce the use of grain and feed. Therefore, as a resource, crop straw can alleviate the shortage of concentrated feed in animal husbandry and reduce feeding costs after silage treatment. [0003] Green corn stalk silage generally needs to add inorganic, organic additives and microbial additives. Inorganic additives include s...

Problems solved by technology

[0004] At present, silage technology has been applied in animal husbandry production, but there are still some shortcomings. The reason is that during the silage process, several microorganisms grow in the same environment, and some microorganisms show mutual inhibition, but not all...
