Problems solved by technology

[0005] However, because the soluble sugar content of alfalfa is too low, the production of lactic acid in the silage process is insufficient, and the pH is difficult to lower to below 4.2, and its buffer energy is high, which easily leads to a negative silage sugar difference, which determines that alfalfa is not easy to carry out conventional silage.

Embodiment 1

[0029] In this embodiment, stevia stalks and alfalfa mixed wrapped silage are made by the following steps:

[0030] (1) Raw material selection and harvesting: Recycling the waste stalks of stevia rebaudiana after utilization, and harvesting alfalfa at the budding stage (the flowering rate is about 3%);

[0031] (2) Kneading, mixing and chopping: Mix 5% stevia stalks and 95% alfalfa evenly by weight, knead and chop into 2-5cm long fragments through a 9FR-15 forage crushing and kneading machine;

[0032] (3) Bundling: The above-mentioned mixed and chopped silage raw materials are compacted and wrapped with high-density 9YQ-1.0 round bale balers to obtain a bale with a size of Φ100cm*85cm and a baling density of 650- 700kg / m 3 , the number of winding layers is 4 layers;

[0033] (4) Wrapping: the mixed silage raw materials of stevia rebaudiana stalks and alfalfa are compacted and bundled with polyethylene stretch film to wrap and seal the bale through the 9YCG-1.0 hanging round...

Embodiment 2

[0036] In this embodiment, stevia stalks and alfalfa mixed wrapped silage are made by the following steps:

[0037] (1) Raw material selection and harvesting: recycle the waste stems of stevia rebaudiana, and harvest the alfalfa when it is approaching the initial flowering period (the flowering rate is about 5%);

[0038] (2) Kneading, mixing and chopping: Mix 8% stevia stalks and 92% alfalfa evenly by weight, and knead and chop them into 2-5cm long fragments through a 9FR-15 forage crushing and kneading machine;

[0039] (3) Bundling: The above-mentioned mixed and chopped silage raw materials are compacted and wrapped with high-density 9YQ-1.0 round bale balers to obtain a bale with a size of Φ100cm*85cm and a bale density of 700- 800 kg / m 3 , the number of winding layers is 4 layers;

[0040] (4) Wrapping: the mixed silage raw materials of stevia rebaudiana stalks and alfalfa are compacted and bundled with polyethylene stretch film to wrap and seal the bale through the 9YC...

Embodiment 3

[0043] The stevia stalk of present embodiment and alfalfa mixed wrapping silage are made by following steps:

[0044] (1) Raw material selection and harvesting: Recycling the discarded stevia stalks after utilization, and harvesting alfalfa at the initial flowering stage (about 7% flowering rate);

[0045] (2) Kneading, mixing and chopping: Mix 10% stevia stalks and 90% alfalfa evenly by weight, and knead and chop them into 2-5cm long fragments through a 9FR-15 forage crushing and kneading machine;

[0046] (3) Bundling: The above-mentioned mixed and chopped silage raw materials are compacted and wrapped with high-density 9YQ-1.0 round bale baler to obtain a bale with a size of Φ100cm*85cm and a bale density of 750- 850 kg / m 3, the number of winding layers is 4 layers;

[0047] (4) Wrapping: the mixed silage raw materials of stevia rebaudiana stalks and alfalfa are compacted and bundled with polyethylene stretch film to wrap and seal the bale through the 9YCG-1.0 hanging rou...

Abstract

The invention provides a stevia rebaudiana Bertoni stalk and alfalfa mixed and wrapped silage feed and a preparation method thereof. The method comprises the following steps of (1) harvesting raw materials: recovering utilized abandoned stevia rebaudiana Bertoni stalks, and harvesting alfalfa from the squaring stage to the early flowering stage; (2) performing kneading, cutting up and mixing: uniformly mixing the harvested stevia rebaudiana Bertoni stalks with the harvested alfalfa, and performing kneading and cutting up through machinery; (3) performing binding: performing high-density compacting and binding on the cut-up silage raw materials; (4) performing wrapping: performing wrapping and sealing on the bound silage raw materials; and (5) performing storage fermentation. According to the stevia rebaudiana Bertoni stalk and alfalfa mixed and wrapped silage feed disclosed by the invention, the stevia rebaudiana Bertoni stalks and the alfalfa are selected as silage raw materials for mixed silage, so that the problem that the alfalfa is low in soluble carbohydrate content, high in buffering energy and difficult in direct ensile can be solved; besides, stevia rebaudiana Bertoni waste residues, stevia rebaudiana Bertoni stalks and the like are also utilized, so that resource waste is reduced, and environmental pollution is reduced; and besides, the source of the silage feed is extended, and the nutrient quality of the silage raw materials is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of silage processing, and relates to silage mixed with stevia stalks and alfalfa and a preparation method thereof. Background technique [0002] Stevia ( Stevia rebaudiana Bertoni ) Alias ​​Stevia, belongs to Asteraceae, Stevie ( stevia ) subgenus, originating in the subtropical region of South America, mainly grows in the undulating hills of the Amambai Mountains adjacent to Brazil in the northeast of Paraguay (about 20° south latitude). Stevia is a plant containing a variety of sweet substances. It has strong adaptability and a wide range of cultivation. Stevia planting areas in my country are mainly distributed in Jiangsu, Anhui, Shandong, Jiangxi and other places. In recent years, the research of stevia has been more and more favored by scientists. From production and planting to extraction and separation, from research on physical and chemical properties to separation of chemical components to modifi...
