The invention discloses a high-yield environmental-protection eggplant cultivation method. The method comprises the following steps: sandy loam soil with no eggplants planted in the preceding crop is selected, soil preparation is carried out, a special fertilizer for eggplants is applied, ridges with a row distance of 40 to 60cm and a height of 16 to 20cm are made through deep tillage and leveling, a greenhouse is built, plump eggplant seeds are selected, seeding boiling, temperature reduction, immersion, cleaning and germination are carried out until 40 to 55% of seeds reveal white, seeding is carried out, fine soil covers the seeds, when a seedling has 4 to 5 leaves, the seedling is put to a cold frame, the nutrient area kept for a single plant is 5*15cm, a small plastic greenhouse covers the seedlings, the temperature is controlled to be 24 to 28 DEG C, ventilation cooling is carried out after rejuvenation, field planting is carried out when the seedling has a height of 20 to 25cm and a leaf number of 6 to 10, the temperature is controlled to be 30 to 35 DEG C and the soil humidity is controlled to be 70 to 85% after field planting, and harvesting is carried out when the eggplants are mature. The method of the invention has the advantages that the cost is low, the yield is high, and the environment is not polluted.
