Embodiment 1

[0006] 500 Clivia grandis seedlings imported from the Netherlands were planted in the following substrate in the No. 17 pot: the substrate in the pot was mixed with Klasmann514# peat soil imported from Germany and perlite at a volume ratio of 4:1, and the pH value was 6.0- Irrigate the whole substrate with 6.8 clean water, spray 800 times of chlorothalonil wettable powder on the plants after 2-4 days of watering, control the temperature at 25-28°C during the day, 18-20°C at night, and the humidity at 70%-80% during the day , 75%-85% at night, light 8000-15000Lux; seven days after the first watering, water with pH 6.0-6.8 when the EC value is > 0.4, and water once per liter of water solution containing Huabao when the EC value is < 0.4 , 4-5 months before the expected flowering, move the mature seedlings of Clivia grandis to the greenhouse, keep the temperature of the greenhouse at 30-32°C during the day and 24-26°C at night, and adjust the light in the greenhouse to 10000-12000...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a cultivation method of Clivia grandiflora in a northern greenhouse. Background technique [0002] Clivia grandis is native to the mountain forests in southern Africa, where the annual temperature is 15-25°C, thus forming the habit of being afraid of cold and heat and requiring a warm, humid and semi-shady environment. It grows slowly below 10°C, relatively dormant below 5°C, and suffers from freezing damage below 0°C; above 30°C, it grows excessively, the leaves are too long, the scapes are too high, and the ornamental value is reduced. During the cultivation process, the environment should be kept moist, the relative air humidity should be 70%-80%, and the soil moisture content should be 20%-30%. Do not accumulate water, especially when the room temperature is low in winter, to prevent root rot. It is not suitable for strong light, and it needs to be cultivated unde...
