The invention discloses a method for cultivating summer-planted film-covered peanut healthy seedlings. The method comprises the following contents: a peanut plant is not covered with a mulching film after seeding but are covered when the peanut plant grows to around a four-leaf stage after seedling emergence; after the peanut plant is covered, a round hole with the diameter of about 5 cm is formed on the mulching film above a seedling so as to expose the seedling outside the film; and an opening of the mulching film is sealed with soil. The method for cultivating summer-planted film-covered peanut healthy seedlings has the advantages of advancing peanut seedling emergence by 1 to 2 days, increasing seedling emergence rate by 8.9 to 15.6 percent, raising healthy seedling rate by 34.3 to 53.4 percent and improving yield by 12.7 to 13.7 percent.
