Problems solved by technology

[0002] If the roots of sweet potatoes (also known as: sweet potato, sweet potato, Latin: Ipomoea batatas) are improperly preserved after harvest, they are easy to rot and deteriorate; waste of resources
The vine leaves of fresh sweet potatoes have high water content and low sugar content, and are not easy to ensilage, so they are rarely used as silage
The usual silage method is mainly to add microbial silage agents to promote the fermentation of silage raw materials, but this method has high production costs, is generally difficult for farmers to master, and has poor operability

Embodiment 1

[0022] According to the weight percentage, the components are: 93.5% sweet potato vines, 0.5% salt and 6% corn flour mixed silage. When the silage is used after 3 weeks, the silage smells sour, the color is greenish yellow, and the sensory evaluation level is good or above. , the pH value is about 4, and the quality of silage is better.

Embodiment 2

[0024] According to the above-mentioned method, the silage weight percentage component is: 86.5% sweet potato tubers, 0.5% salt and 13% rapeseed meal mixed silage, when silage was used after 3 weeks, the silage smell was a sour fragrance, and the color was yellowish brown. The sensory evaluation grade is above good, the pH value is about 4, and the quality of silage is good.

[0025] The silage of the present invention is used to feed growing and finishing pigs, whose daily gain is above 0.4Kg, and the feed-to-meat ratio is below 3.5, and the feeding effect is very good.

Abstract

A method for storing the vine or tuber of sweet potato includes cutting said vine short or beating said tuber, proportionally mixing the vine with salt and corn powder or mixing the tuber paste with salt and rapeseed cake powder, loading in storage bags, and storing.

Description

technical field [0001] The invention relates to a silage method for crops, in particular to a silage method for sweet potato vines or sweet potato tubers. Background technique [0002] If the roots of sweet potatoes (also known as: sweet potato, sweet potato, Latin: Ipomoea batatas) are improperly preserved after harvest, they are easy to rot and deteriorate; waste of resources. The vine leaves of fresh sweet potatoes have high water content and low sugar content, and are not easy to be silaged, so they are rarely used as silage. The usual silage method is mainly to add microbial silage agents to promote the fermentation of silage raw materials, but this method has high production costs, is generally difficult for farmers to master, and has poor operability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a silage method of sweet potato vines or sweet potato tubers, which is simple in operation, low in producti...
