Ice plant cultivation process in plant factory

The invention specifically relates to an ice plant cultivation process in a plant factory. The ice plant cultivation process comprises the following steps of: 1, seedling culture, namely putting a sponge block into a seedling culture plate, uniformly pressing the sponge block to make the sponge block absorb water fully, and then putting ice plant seeds into the sponge; 2, seedling management, namely after the seeds are germinated, transferring the plate into an environment with a fill light, wherein chromatography of the fill light is red:yellow:blue=3:1:2, and replacing clean water in the seedling culture plate by a nutrient solution after two cotyledons appear on each seedling; 3, field planting, namely after three euphyllas appear on each seedling, and starting to carry out field planting; 4, management after field planting, namely keeping exposing the seedlings under combined white light for filling; and 5, pickling, namely after side buds of ice plants grow, picking leaves of the ice plants.
