Embodiment 1

[0019] Embodiment 1: screening suitable mixing ratio

[0020] 1 Material method

[0021] 1.1 Test material

[0022] The test materials were planted in the experimental field of Grassland Station, Shigatse City, Tibet Autonomous Region, and were cut on September 7, 2010. Wheat (Triticum aestivum L.) was the stalk after the seeds were harvested, and perennial ryegrass (Lolium perenne L.) was cut For the heading period. After harvesting, they were quickly sent back to the laboratory of Shigatse Grassland Station to make silage. The silage cellar is a laboratory silo cellar with 1L plastic container.

[0023] 1.2 Experimental design

[0024] This experiment was divided into control group and three treatment groups, control group (Control): 100% wheat straw; treatment one (XH15): 85% wheat straw + 15% perennial ryegrass; treatment two (XH35): 65% wheat straw + 35% perennial ryegrass; treatment three (XH55): 45% wheat straw + 55% perennial ryegrass, with three replicates per gr...

Embodiment 2

[0043] Embodiment 2: Screening of suitable biological additives

[0044] 1. Material method

[0045] 1.1 Test material

[0046] 65% wheat straw + 35% perennial ryegrass as materials.

[0047] The cellulase preparation is cornzyme cellulase (Bao Kangsheng), the main components include cellulose, hemicellulose and glucose oxidative cellulase. It is a special additive for silage developed by Finland Feed International Co., Ltd. (FFI), and the addition amount is used as reference illustrate. 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.

[0048] The preparation method of the lactic acid bacteria compound additive is as follows:

[0049] 1) MRS medium: peptone 10.0g; beef extract 10.0g; yeast extract 5.0g; glucose 20.0g; Tween 1mL; ammonium citr...

Abstract

The invention discloses a wheat straw and perennial ryegrass containing silage composition and application thereof. The wheat straw and perennial ryegrass containing silage composition consists of the following components in parts by fresh weight: 50 to 80 parts of wheat straws, 20 to 50 parts of perennial ryegrass, a cellulase preparation and a lactobacillus composite additive, wherein the lactobacillus composite additive consists of lactobacillus plantarum, bacillus subtilis and glucose. According to the wheat straw and perennial ryegrass containing silage composition and the application thereof, a specific fermentation promoter combination is selected from a plurality of fermentation promoters according to the characteristics of the wheat straws and the perennial ryegrass, so that the fermentation quality of mixed silage feed is remarkably improved, and the wheat straw and perennial ryegrass containing silage composition is low in cost, safe, reliable and easy to use.

Description

technical field [0001] The invention belongs to the technical field of forage preparation and processing and application of biological additives, in particular to a silage composition containing wheat straw and perennial ryegrass and its application. 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, the grassland overload rate in Tibet's pastoral areas is as high as 80%. More than / 2 is seriously degraded, and about 1 / 3 is 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 for pastoral areas in northern Tibet, relieve the pressure of overloading and overgrazing grasslands ...
