由于二氧化硫能够抑制葡萄果粒上的真菌,能一定程度上降低果实的呼吸强度,提高果穗的贮藏质量,因此,用二氧化硫熏蒸贮藏葡萄,已作为一项新技术在生产上应用。应用三氧化硫熏蒸贮藏葡萄,主要有两种方法:一是用二氧化硫气体直接熏蒸,二是用重亚硫酸盐缓慢释放二氧化硫熏蒸贮藏。直接熏蒸法,多用于密闭冷库中,不及用重亚硫酸盐法方便。应用重亚硫酸盐法熏蒸贮藏时,要先 As sulfur dioxide can restrain grape fungus on the grain, can reduce the respiration intensity of the fruit to a certain extent and improve the storage quality of the ear, therefore, the use of sulfur dioxide to fumigate the stored grape has been applied as a new technology in production. The application of sulfur trioxide fumigation storage of grapes, there are two main ways: First, direct fumigation with sulfur dioxide gas, and second, the slow release of sulfur dioxide with bisulfite fumigation storage. Direct fumigation, mostly used in closed cold storage, less than the convenience of bisulfite method. Application of bisulfite fumigation storage, first
