What are the production methods of corn straw yellow storage?
Yellow storage refers to the short-term storage and fermentation of yellow straw after grain harvest, which is called yellow storage Straw silage is a kind of feed produced by putting green straw into honey seal (silage cellar and soil cellar) and using microbial fermentation process, which is called straw silage;

The processing methods of silage and yellow storage are basically the same except that the freshness and water content of corn straw are slightly different.

After harvesting, the corn stalks are crushed and then put into a fermentor for compaction or block coating. When the moisture content of corn stalk exceeds 70% in the process of silage, it should be dried properly or hay powder should be added to reduce the moisture content.

When the moisture content of corn stalk is lower than 45% during yellow storage, water should be sprayed appropriately to increase the moisture content, and the moisture content is 60%~65%, which is most beneficial to fermentation. If possible, probiotic liquid can be sprayed when corn stalks enter the pond to promote fermentation.

Finally, after filling, cover and seal with plastic sheets to prevent air from entering and deteriorating. Generally, after 15~20 days of fermentation, corn stalks can be used in pits and can remain unchanged for 2 years under good sealing conditions.

Characteristics of straw silage yellow storage

1, the nutritional value of silage is higher than that of yellow storage. However, although the nutrition of yellow storage is lower than silage, the raw materials of yellow storage are corn straw, wheat straw, cereal grass, potato seedlings and so on. After harvest, the grain is more abundant and extensive than silage, and its cost is low, which meets the people's wishes and is welcomed by farmers. Both storage methods have their own advantages, and which one to use depends on your own raw materials.

2. Storage and feeding can prolong the storage period of corn straw, improve the utilization rate of straw, reduce nutrient loss and occupy a small area.

3. Straw silage is similar to yellow storage, which is easy to learn and popularize. ?

4. Good palatability and high feed intake; After straw silage is stored in yellow, the hard straw can be softened, and lignocellulose can be degraded in large quantities, which can be converted into lactic acid and volatile fatty acids. The acid is fragrant and stimulates the appetite of livestock, thus improving the feed intake. The feed intake speed of cattle and sheep can be increased by 30%-40%, and the feed intake can be increased by 20%-30%.
