The invention discloses a cultivation method of clivia miniata in a greenhouse of northern China. The method comprises the following steps: planting young seedlings of clivia miniata in a matrix formed by turfy soil and perlite used in a mixed manner in the volume ratio of (4:1) to (5:1); thoroughly pouring the overall matrix with clear water with the pH value being 6.0-6.8; watering for 2-4 days, and comprehensively spraying 800-fold liquid of chlorothalonil wettable powder on the plants; transferring mature seedlings of the clivia miniata into the greenhouse at 4-5 months before an expected flowering period; keeping the temperature of the greenhouse at 30-32 DEG C and the temperature at night at 24-26 DEG C; adjusting the illumination in the greenhouse to 10,000-12,000Lux; and regularly fertilizing, namely applying a balance fertilizer along with water for once a week in the ratio of N to P to K being 20 to 20 to 20.
