Chinese Redbud flowers are beautiful, with large amounts of flowers, bright colors, and are an important ornamental shrub in spring. Chinese Redbud has strong adaptability to the environment, good transplant survival rate, low price and green effect, and is deeply welcomed by all places. How does Chinese Redbud propagate? Here are 4 propagation methods of Chinese Redbud.
From September to October, mature pods were collected, seeds were taken out, and buried in the dry sand in the shade for wintering. Sow seeds from late March to early April, and treat seeds before sowing, so as to achieve vigorous and vigorous seedling. Soak the seeds in 60℃ warm water, then continue to soak for 3-5 days after the water cools. Cold water should be changed once a day. After the seeds are expanded by absorbing water, they are put in an environment of 15℃ for accelerating germination.
Doused with warm water 1-2 times a day, to be exposed to white after sowing in the seedbed, 2 weeks can be the seedlings, seedlings after the appropriate thinning.4 true leaves when transplantable nursery, bed with loose fertile loam had better. For ease of management, the planting should be narrow, 60 cm wide and 40 cm narrow, with plants 30 cm to 40 cm apart. Seedling period is not cold, winter with plastic arch canopy protection over the winter.
When chinese redbud is growing, its root is easy to produce root tillering. The lateral roots connecting the tiller seedlings to the mother plant are usually broken with a sharp knife before germination in autumn or spring, and then another transplant is performed, which makes survival easier. When plants are divided in autumn, it is necessary to pay attention to the changes in the growth environment temperature of Chinese Redbud, protect it for overwintering, and wait until march of spring for planting.Generally the second year can flower.
Layering in the growing season can be carried out, with spring march - April better. Chinese Redbud layering method can choose 1 to 2 years old branch, cut with a sharp knife and ring stripped bark about 1.5 cm, exposed xylose, root powder liquid (diluted according to the instructions) coated in the top of the carved part about 3 cm, to be dry with a tubular plastic bag set in the carved part, filled with loose garden soil, watering both ends tie can be.
Check after 1 month. If the soil is too dry to hydrate, root after cutting another plant. Thicket type tree can be chosen periphery is more fine and soft, 1-2 year old branches will be base incised, coated with root powder liquid. After a sharp bend buried in the earth, the upper pressure brick fixed, the top tip can be supported by sticking upright. Generally in the second year in March, divide another plant. Some branches do not root, and we can continue to bury pressure. In the second year, they can root.
Grafting is carried out in the summer growing season. Cut off the young shoots of the year for cuttings, inserted in the sand can also survive, but not commonly used in production. Common Chinese Redbud and giant Chinese Redbud with strong growth can be used as rootstock. However, because giant Chinese Redbud has poor cold resistance, it is not suitable for use in northern China. The scion can be made of buds or branches of excellent varieties such as Canadian red leaf and Chinese Redbud.
