Embodiment 1

[0019] Embodiment 1: screening suitable mixing ratio

[0020] 1 Material method

[0021] 1.1 Test material

[0022] The highland barley (Hordeum vulgare L.) and reed fescue (Festuca arundinacea) planted in the experimental field of grassland workstation in Tibet were harvested. Highland barley stalks are the stalks after the grains have been removed, and the reed-like fescue is in the early heading stage when it is cut. After harvesting, use a guillotine to cut into about 2cm in the field. The mixing ratio is: 100% highland barley straw (Control); 80% highland barley straw + 20% reed fescue (QW20); 60% highland barley straw + 40% reed sheep Mao (QW40); 40% highland barley straw + 60% reed fescue (QW60), each group was repeated three times.

[0023] 1.2 Test method

[0024] 1.2.1 Preparation of silage

[0025] After harvesting on August 24, 2010, it was cut into 2cm with a guillotine in the field. After the stems and leaves were fully mixed, they were weighed according to ...

Embodiment 2

[0041] Embodiment 2: Screening of suitable biological additives

[0042] 1. Material method

[0043] 1.1 Test material

[0044] 60% highland barley straw + 40% reed fescue as materials.

[0045] The cellulase preparation is cornzyme cellulase (Bao Kangsheng), the main components include cellulose, hemicellulose and glucose oxidase. It is a special additive for silage developed by Finnish Feed International Co., Ltd. (FFI). The amount of addition refers to the instructions for use. The lactic acid bacteria compound additive is composed of 60% Lactobacillus plantarum freeze-dried powder, 20% Bacillus subtilis freeze-dried powder and 20% glucose by weight. Lactobacillus plantarum and Bacillus subtilis were purchased from Shanghai Fusheng Biotechnology Co., Ltd.

[0046] The preparation method of the lactic acid bacteria compound additive is as follows:

[0047] 1) MRS medium: peptone 10.0g; beef extract 10.0g; yeast extract 5.0g; glucose 20.0g; Tween 1mL; ammonium citrate 2.0g...

Abstract

The invention belongs to the technical field of ensilage processing, and relates to an ensilage combination including barley straws and festuca arundinacea and application thereof. The ensilage combination including the barley straws and the festuca arundinacea consists of the following components by fresh weight: 50 to 70 parts by weight of the barley straws, 30 to 50 parts by weight of the festuca arundinacea, cellulase preparation and lactic acid bacteria compound additive, wherein the lactic acid bacteria compound additive consists of lactobacillus plantarum, bacillus subtilis and glucose by dry weight. The ensilage combination can be applied to silage production. A particular fermentation enhancer combination is chosen from a plurality of fermentation enhancers according to the characteristics of the barley straws and the festuca arundinacea, and therefore, the fermentation quality of mixed silage is obviously improved. The ensilage combination including barley straws and festuca arundinacea has the advantages of low cost, high safety and reliability and simplicity in application.

Description

technical field [0001] The invention belongs to the technical field of silage processing, and relates to a silage composition containing highland barley straw and reed-shaped fescue and an application thereof. Background technique [0002] Due to Tibet's special geographical location and ecological conditions, animal husbandry occupies a very important position in the whole region. However, at present, the grassland overload rate in pastoral areas of Tibet is as high as 80%. Excessive overloading and grazing have caused more than 50% of the usable grassland to be degraded to varying degrees, of which more than 1 / 2 are seriously degraded and about 1 / 3 are desertified. Grassland degradation has led to increasingly prominent contradictions between grassland and livestock, seriously restricting the sustainable development of Tibet's animal husbandry. Implement high-quality pasture planting, processing and storage in the agricultural areas of Tibet to provide high-quality silage...
