The invention provides a method for improving forage grass production performance and silage quality and application of the method, and belongs to the technical field of silage production. The method comprises the following steps that after silage corn is sown, lacroton beans are sown between two rows of corn immediately; first topdressing is carried out 18-22 days after sowing; carrying out secondary topdressing 60-68 days after sowing; harvesting is conducted on the 105th-110th day after sowing is conducted; and carrying out silage on the harvested silage corn and the harvested lacroton beans. Through mixed sowing of the corn and the lab beans, the dry matter yield and the crude protein content of the mixed forage grass are improved, supply of protein raw materials in concentrated feed is reduced, and the feed cost is reduced. The abundance of leuconostoc can be remarkably reduced during the ensiling period, and the silage obtained after ensiling is excellent in sensory evaluation. The content of nutritional ingredients in the silage is changed, protein and carbohydrate components are changed, and the nutritional value of the silage is improved.

The strain is outstanding in the production of fermented squid-flavor soy sauce and the development of low-purine fermented food, can specifically degrade four types of main purines, namely, adenine, guanine, hypoxanthine and xanthine, effectively solves the problem of excessive purine in traditional squid-flavor soy sauce, and provides a core strain for the industrialization of low-purine seafood soy sauce.

The invention discloses a method for improving the quality of sugarcane tip silage through lactic acid bacteria-saccharomycetes synergistic fermentation. The method comprises the following steps: (1) preparing silage raw materials; (2) preparing bacterial suspension of lactic acid bacteria and saccharomycetes; and (3) preparing and storing the silage. According to the method, based on the high-sugar raw material characteristic of sugar cane tips, lactic acid bacteria and saccharomycetes are added to synergistically regulate and control the quality of the sugar cane tip silage, and lactic acid bacteria (lactobacillus or lactococcus and leuconostoc) and saccharomycetes (candida boidinii and pichia kudriavzevii) are used for synergistically anaerobic fermentation in the silage process, so that the quality of the sugar cane tip silage is improved. The substrate sugar is decomposed to generate a large amount of lactic acid, and the pH value of the feed is effectively reduced, so that the growth of harmful microorganisms is inhibited, the generation of ethanol is reduced, more nutritional ingredients are retained, and the quality of the sugar cane tip silage is further improved.
