Bellflower, also known as bell flower, is bell-shaped, bright and elegant. It is a common herb flower in small gardens in late spring and early summer, and is often used to express healthy and gentle love. Campanulaceae, Campanula, has about 300 varieties, annual, biennial or perennial herbs. The flowers are bell-shaped, usually blue, and there are many cultivated and ornamental varieties. Sow and breed. Sow the seeds as soon as they are ripe, and the plants can blossom in the next year. If you sow in autumn, most seedlings will not bloom until the end of the third spring.
The following is information to help you find. Personally, I suggest you dig some soil in the wild and raise it according to its original environment. No problem if you don't die or drown. I always take things to the wild and then come back to raise them.
Management:
Pay attention to wintering and cold protection, and need a low-temperature greenhouse. The Yangtze River basin needs cold bed protection. When the seedlings pass the summer, they should be shaded to a certain extent to avoid strong sunlight.
Germination stage-preparation stage
Acupoint method: it is recommended to use a large plug, such as No.200 plug. Using plug to cultivate bellflower can save seedbed space, because the germination time of bellflower is long and the young leaves grow slowly.
PH value of substrate: 5.5-6.0
Germination stage-stage 1
The radicle appeared in 10- 12 days.
Appearance characteristics: 1 Late stage, radicle has appeared.
Saturated moisture: Sow in the substrate. Water must be kept at the top of the substrate and seeds cannot be covered.
Humidity: Relatively high humidity should be maintained before radicle appears.
Substrate temperature:? 60-65 degrees Fahrenheit (15- 18 degrees Celsius)
Matrix EC: < 0.5
Germination stage-second stage
Appearance characteristics: at the late stage of the second stage, the root length is 1.27-0.64 cm, and cotyledons have appeared.
Moisture: The substrate should be wet, but unsaturated to prevent wilting due to too little moisture. When necessary, new seedlings should be covered with a layer of coarse vermiculite to keep moisture.
Basement temperature: see stage 1.
Fertilization: Bellflower only needs a small amount of fertilization. If the seedlings want to grow rapidly, calcium fertilizer can be applied on the basis of applying 30-50PPM calcium nitrogen fertilizer.
Matrix Ec value: 0.5-0.75
Light: Short-term light can promote the growth of crops. Germination does not require light.
Germination stage-the third stage
Appearance characteristics: at the end of the third stage, the root system was deeply embolized and several true leaves appeared.
Moisture: The substrate should be slightly wet, but it should not be soaked to prevent the seedlings from wilting due to excessive drying.
Humidity of the substrate: see stage 1.
Fertilizer: See Phase 2.
Matrix Ec value: See Phase 2.
Lighting: See Phase 2.
Germination stage-stage 4
Appearance characteristics: at the end of the fourth stage, root system? Full of holes. Moisture: during the two watering, keep the substrate slightly dry, but don't let the plants lack water?
Wilt.
Basement temperature: 58-60 degrees Fahrenheit at night (14-60 degrees Celsius) and 65-70 degrees Fahrenheit during the day (18-2 1 degrees Celsius).
Fertilization: See the second stage.
Matrix Ec value: See Phase 2.
Lighting: See Phase 2.
growing period
Similar to Begonia, Bellflower begins to grow slowly, but before the root system grows, the plant should be moved to the last growth pot.
Substrate: It is particularly important to choose a porous substrate with good drainage performance when the temperature and light are low in autumn and winter and the substrate dries slowly.
PH value of substrate: 5.5-6.0
Moisture: between watering, the substrate can be slightly dry, but plants should not wither due to lack of water.
Temperature: 58-60 degrees Fahrenheit at night (14-60 degrees Celsius) and 65-70 degrees Fahrenheit during the day (18-2 1 degrees Celsius). When active roots grow, the temperature can be reduced to 50-55 F (10-6544) at night.
Fertilization: If the rapid growth of plants requires fertilization, apply 100-50PPM nitrogen fertilizer.
Matrix Ec value: 1.0. Stella series is sensitive to salt, and the Ec concentration can be reduced from time to time if necessary.
Illumination: Campanula likes long sunshine, and it can bloom naturally when it is illuminated 14 hours a day. If you want to blossom early, you need an intermittent night of 30 days and 4 hours. When 15 true leaves appear, carry out light treatment. If the plant is too small at the initial stage of light and only grows once, the secondary growth will be in a state of vigorous growth.
Growth regulation and enucleation: bluebells do not need growth regulation and enucleation. In the early stage of growth, the appearance of bluebells is chaotic, but in the later stage of growth, the plants will naturally be neat and compact.
Conventional pests:? Thrips, spider tapeworms.
Common diseases:? Tomato mosaic virus.
Planting arrangement: Campanula is a cool-loving plant, which should grow for several months in winter and complete its life cycle in the following spring. The illumination time should be at least 14 hours per day, and the viewing period is long. It takes about 30 days from germination to flowering. If it is treated by long sunshine, it should be planted in 165438+ 10. Under natural conditions, it can grow in summer.
