Prunus Triloba has high ornamental value because its leaves are like elm leaves and its flowers resemble plum blossoms. There have been hundreds of years of cultivation of Prunus triloba in Our country. Now let's find out the propagation methods of Prunus Triloba.
The propagation methods of Prunus Triloba include grafting propagation, splitting propagation, layering propagation, cuttage propagation and seed propagation. Among them, the common propagation of Prunus Triloba methods are plant division propagation and grafting propagation.
Plant division propagation of Prunus triloba is usually carried out in the fall and spring before plant germination after soil thawing. The whole plant is dug out of the soil. Then, with a sharp knife, the plant is divided into branches, each with a certain amount of roots. Before transplantation, the damaged branches should be cut off completely at the neck, and the remaining branches should be left about 10 cm short. Take good care after transplant, or die easily.
There are two kinds of grafting reproduction: bud grafting and graft grafting. It is advisable to bud grafting in mid-to-late August. Rootstock can be annual Prunus triloba seedlings, or wild Rose plants, peach, peach seedlings. The new buds can be selected from the Prunus Triloba plant of excellent species and the plump leaves from the annual branches can be cut for use. Grafting should take place in February and March of the spring. The scion should be cut before the plant sprouts. Scions can also be intercepted in winter and stored in sand for use in spring. The graft is usually rooted from 1-2 year old apricot, peach and Prunus triloba. Cutting before budding in spring; Buds bud in July - August; The graft can be separated from the mother plant before June and healed after 1 to 2 months. After the completion of grafting, we should pay attention to the management of grafting. When the grafting branch dies, we should make up in time.
Cuttage is generally carried out in the late spring and early autumn. Generally choose the branches of the current year to carry out the twig cutting, or in early spring to carry out the old twig cutting with the branches of the last year. The medium used for cutting is generally nutritive soil or river sand, clay carbon soil and other materials. It is difficult to get the ideal cutting substrate under the condition of family cutting, so it is suggested to use the prepared and sterilized cutting substrate. Medium coarse river sand is fine, but wash it with water several times and expose it to the sun for a few days before use. Care should be taken to avoid sunlight after cutting and to keep the soil moist.
Select robust branches, from the top tip below about 15 ~ 30 cm place bark stripped off a ring, strip after the wound width in a centimeter or so, the depth to just skin stripped off for the limit. Cut a piece of film 10 ~ 20 cm long and 5 ~ 8 cm wide, put some wet Garden earth on it, wrap up the part of ring stripping like a wound, tie up the upper and lower ends of the film and bulge in the middle.It takes about four to six weeks to take root. You can also bend the branches to the ground and then dig a hole to bury the middle and keep the top of the tree out of the ground. After taking root, you cut off the roots along the side of the branch to make a new plant.
Prunus Triloba seeds can be divided into autumn and spring sowing. Autumn sowing is usually carried out in mid-October and late October, and spring sowing is carried out in late April or early May after the weather warms up. It's best to disinfect the soil before sowing Prunus triloba, and appropriate compost can be added to increase the fertility of the soil. Water the seeds after sowing to keep the soil moist. Keep the seedlings warm and moist after emergence. When the seedlings grow 4-6 true leaves, they can be transplanted to other places for cultivation.
