Quick Seedling Raising Method of Inverted Bell Flower
An explanation for netizens who are concerned about the aspects of inverted bell flower propagation, the quick seedling raising method of inverted bell flower, details are as follows:
The inverted bell flower, also known as吊钟海棠 or lantern begonia, is native to South America and is a perennial semi-shrub or small shrub. When the flowers bloom, they look like inverted golden bells with bright colors, which are deeply loved by people. The inverted bell flower is sensitive to temperature, and growth will be affected if the temperature is below 5℃ or above 30℃. Now, the main points of the quick seedling raising method using paper钵 for inverted bell flowers are summarized as follows.
One, prepare nutrient-rich paper钵. Take some old newspapers (four-page spread) and fold them into three folds horizontally, then cut into strips about 54 cm long and 13 cm wide. Take a pop can, wrap the cut strip around the top of the can, leaving 3 to 5 cm, and secure the joint with glue. Flatten the protruding part inward and slide it off to form a nutrient-rich paper钵 that is 8 to 10 cm high and 6 cm in diameter.
Two, prepare the growing soil. Take coal cinder, decomposed leaf soil or decayed sawdust, and a small amount of garden soil, crush and mix them evenly, spread them out for sunning and disinfection, or use a 50 to 100 times formalin solution for disinfection. Then, sprinkle in an appropriate amount of water and sieve while wet. Also, prepare several mud balls about 1 cm in diameter using yellow clay or disinfected soil.
Three, cutting operation. Cuttings can be done throughout the year, with the best periods being from mid-March to mid-April and from mid-September to late October. Cut branches with 2 to 3 nodes as cuttings, about 10 cm long, using a sharp blade to reduce mechanical damage to the stem tissue. Keep 1 to 2 pairs of leaves on the top of the cutting and remove the leaves from the bottom. Insert the cutting into the prepared mud ball, with the depth being half the diameter of the mud ball. Finally, place the cutting with the mud ball into the paper钵 filled with growing soil, and cover with a little more soil until the mud ball is buried, planting one seedling per钵.
Four, post-cutting care. The young seedlings need to be shaded for a week after cutting, and then can be maintained conventionally. On sunny and windy days, pay attention to strengthen foliar watering and keep the soil surface moist. Generally, roots can grow within 15 to 30 days after cutting. After rooting, a mixture of 1% to 2% urea and potassium dihydrogen phosphate solution can be sprayed or watered to promote plant growth. Once the new roots penetrate the paper钵, they can be transplanted into pots.
Using this method, the spring cuttings will usually shape up by the end of June to early July of the same year after 1 to 2 times of pinching, and have a certain resistance to high temperatures. With some shading in the summer, they can bloom without obvious summer dormancy. If it is autumn cuttings, they have strong cold resistance and can be placed in a sunlight greenhouse for overwintering without heating. The young seedlings can tolerate short periods of 0℃ and long periods of 1℃ low temperatures, but may show symptoms such as red veins and curled leaves. If the temperature can be maintained above 2℃, the young seedlings can safely overwinter and will bloom by the end of May the following year. The suitable temperature for overwintering cuttings is between 3℃ to 6℃, as high temperatures can cause the plants to elongate.
The quick seedling raising method using paper钵 is simple and easy to perform, solving the problem of summer dormancy and cold intolerance of inverted bell flower seedlings. Under natural conditions, the flowering period can last 6 to 7 months. The disadvantage is that the paper钵 is prone to rot and should not be exposed to rain for long periods.
