Low-temperature-resistant lactobacillus plantarum, application of low-temperature-resistant lactobacillus plantarum in jerusalem artichoke silage and fermentation device Technical Field The invention relates to the technical field of lactic acid bacteria, in particular to low-temperature-resistant lactobacillus plantarum, application of the low-temperature-resistant lactobacillus plantarum in jerusalem artichoke silage and a fermentation device. Background Jerusalem artichoke is taken as a biomass resource with high yield and strong adaptability, and is an excellent silage raw material. However, in cold areas or winter, conventional silage fermentation processes are often inhibited by excessively low ambient temperatures. The low temperature can obviously reduce or stop the activity of beneficial microorganisms such as lactobacillus and the like, so that silage fermentation is slow to start, acid production is insufficient, putrefying bacteria are easy to breed, the quality of silage is reduced, nutrition is lost, and even fermentation fails. In the preparation process of silage, the fermentation agent is uniformly inoculated and fully mixed with the materials, so that the key of ensuring the fermentation quality is realized.
