The invention belongs to the field of biological prevention and control of
postharvest diseases of
fruits and vegetables, and relates to application of
saccharomyces cerevisiae in
postharvest diseasecontrol, storage and preservation of baby Chinese cabbage. The application of controlling the
postharvest diseases comprises the steps of selecting vegetable leaves of the baby Chinese cabbage, airingwith disinfection, washing with clear water, putting into a sterile plastic basket, airing, uniformly spraying a
saccharomyces suspension on the surfaces of the vegetable leaves, standing, spraying an
alternaria tenuissima
spore suspension, naturally airing, and sealing with a
preservative film, thereby controlling the
black spot disease of the baby Chinese cabbages; the application for storage and preservation comprises the following steps of putting the baby Chinese cabbages in the disinfected plastic basket, uniformly spraying
saccharomyces suspension on the surfaces of the baby Chinese cabbages, naturally airing the baby Chinese cabbages, sealing the baby Chinese cabbages with a
preservative film, and storing the baby Chinese cabbages at the temperature of 20 DEG C to realize prevention and treatment of diseases of the postharvest
disease control and storage and preservation of the baby Chinese cabbages. The application is safe and environment-friendly, not only can effectively control the postharvest
black spot disease, but also can slow down the reduction of the quality of the baby Chinese cabbage to a certain extent, the postharvest
black spot disease can be controlled through the application which can replace chemical bactericide, and the potential application value is achieved.
