The invention relates to a method for cultivating eggplant with plastic mulch, which improves the utilization ratio of nutrients of eggplant by means of seedling and raising, soil preparation and fertilization, covering plastic film, transplanting and field management, thereby improving the yield and quality of eggplant. Compared with the open field cultivation, the content of soluble sugar, soluble protein and rutin in the eggplant fruits in plastic mulching cultivation increased by 21.45%, 8.0% and 18.43%, respectively. The method can also inhibit the growth of weeds, reduce the use of herbicides, save time for manual spraying, finally reduce production costs.
