Abstract

The invention provides an enzyme method ensilage method of corn straws. An enzyme preparation composition containing assistants is used to process small segments of corn straws, the processed corn straws are triturated, and a combined fermentation bacterium is added to carry out accumulative fermentation, so the content of utilizable nutritional substances of a yellow ensilage feed is improved, and the palatability is improved. An aflatoxin B1 clastic enzyme and denitrifying bacteria are simultaneously introduced, so harmful substances comprising aflatoxin, nitrite and the like in the yellow ensilage process and the yellow ensilage feed are eliminated, and the safety of each of the corn straws and the yellow ensilage feed is improved.

Description

technical field [0001] The invention relates to a yellow storage process, in particular to an enzymatic yellow storage method for corn stalks. Background technique [0002] Corn is the main food crop in my country, with an average annual planting area of ​​about 5972h㎡. As a by-product of corn production, corn stalks have an output of about 230.1 million tons. Due to the difficulty in collection and high transportation costs, a small part of silage and yellow silage are used as cattle and sheep Feed or used as raw materials for papermaking, most of them are directly returned to the field or incinerated. [0003] At the same time, due to policies such as closing mountains for afforestation, the source of food for grazing livestock such as cattle and sheep has been greatly affected. One of the solutions is to use crop straw as their feed. Traditional silage and yellow silage have strong seasonality, and the energy in the feed is relatively low. The fermentation process is also...
