Embodiment 1

[0036] Get 0.5 part of table salt, 0.5 part of urea, 1 part of citric acid, 1 part of molasses (both parts by weight), be dissolved in 3 parts of water (parts by weight) and stir, evenly spray on 97 parts of bamboo shoot shells (bamboo shoots) with a high-pressure sprayer The weight water content of the shell is 60%), fill the well-mixed bamboo shoot shells in the green storage cellar as soon as possible (complete within 2 days), fully compact, the top is rounded after filling, and the surface is covered with two layers of polyethylene film , to ensure adequate sealing. After 15 days of silage, check the pH of the silage liquid flowing out from the crack of the wooden door at the bottom of the silo every day. When the pH drops below 4.0, it indicates that the silage is over.

Embodiment 2

[0038] Get 0.4 part of table salt, 0.4 part of urea, 0.2 part of citric acid, 0.8 part of molasses (both parts by weight), dissolve in 3 parts of water (parts by weight) and stir evenly, evenly spray on 98.2 parts of bamboo shoot shells (bamboo shoots) with a high-pressure sprayer The weight water content of the shell is 65%), fill the well-mixed bamboo shoot shells in the green storage cellar as soon as possible (complete within 2 days), fully compact, and the top is round after filling, and the surface is covered with two layers of polyethylene film , to ensure adequate sealing. After 15 days of silage, check the pH of the silage liquid flowing out from the wooden door crack at the bottom of the silo every day. When the pH drops below 4.0, it indicates that the silage is over.

Embodiment 3

[0040] Get 0.2 part of table salt, 0.2 part of urea, 0.6 part of citric acid, 0.5 part of molasses (both parts by weight), be dissolved in 3 parts of water (parts by weight) and stir evenly, evenly spray on 98.5 parts of bamboo shoot shells (bamboo shoots) with a high-pressure sprayer The shell weight water content is 70%), fill the mixed bamboo shoot shells in the green storage cellar as soon as possible (complete within 2 days), fully compact, the top is round after filling, and the surface is covered with two layers of polyethylene film , to ensure adequate sealing. After 15 days of silage, check the pH of the silage liquid flowing out from the wooden door crack at the bottom of the silo every day. When the pH drops below 4.0, it indicates that the silage is over.

Abstract

The invention relates to the field of a silage method and aims at providing a method for preparing silage by using bamboo shoot shells and a silage pit. The method for preparing the silage by using the bamboo shoot shells comprises the following steps: collecting the fresh bamboo shoot shells and airing, mixing and uniformly stirring the bamboo shoot shells with table salt, urea, citric acid and molasses, placing the mixture into the silage pit to be sealed until an ensiling process is finished, and thus preparing the bamboo shoot shell mixture in the silage pit into the silage. The periphery of the silage pit is in a structure defined by cement walls and the vertical longitudinal section of the silage pit is trapezoid; lanes are arranged on one side of the top of the silage pit and one side of the bottom of the silage pit; and one side of the bottom of the silage pit is provided with a door capable of being nailed up by using a wood plate. The silage with good palatability and abundant nutrition, provided by the invention, can be directly used as a feed for ruminants in South China, so that grains are saved and guarantees are provided for sustainable development of a bamboo shoot processing industry.

Description

technical field [0001] The invention relates to the field of silage methods, in particular to a method for preparing silage from bamboo shoot shells and a silage pit. Background technique [0002] The inedible shells and bamboo shoots cut off during the processing of bamboo shoots are collectively called bamboo shoot shells, and the weight of bamboo shoot shells accounts for about 74.35% of the weight of the whole bamboo shoots. Studies have shown that the nutritional content of fresh bamboo shoot shells is relatively high, among which the crude protein content is 8.12%-12.7%, which is higher than that of straw feed such as corn stalks; the crude fat accounts for about 1.42%-1.74%, and the neutral detergent fiber accounts for about 75.3%-78.9% , crude ash accounts for about 4.28%-8.68%, which is similar to common roughage such as corn stalks; in addition, it is also rich in various biologically active substances such as phytosterols and polysaccharides, which can improve the...
