Grafting propagation of Magnolia mandshurica

Magnolia, also known as Magnolia, Magnolia and so on, generally blossoms in mid-late March. Because Magnolia magnolia is difficult to plant and is an endemic plant in China, its reproductive survival rate is also relatively high. Magnolia can be propagated by sowing, grafting, cutting and other methods. What the editor here introduces to you is the grafting propagation of Magnolia.

I. selection and treatment of Magnolia rootstocks

The rootstock should choose the inferior species in the early and full bud stage with no budding or less budding. First saw the crown from the main branch. The horizontal height from the ground should be close to avoid the imbalance of the main branches caused by the top dominance, the upper main branch should be shorter than the next main branch, and the height of the main trunk should be slightly higher than that of the uppermost main branch. The interface should be selected in a smooth place, and the saw blade should be flattened with a cutter.

2. Selection and treatment of scion

The excellent varieties of monkey palm string elm, big hairy peach string elm or two-hairy peach string elm should be selected for scion, and the annual branches with strong growth, full development and free of diseases and insect pests should be selected.

The grafting technique should be carried out before and after sprouting in spring to the stage of leaf expansion. Generally for the middle and late March, only work axillary buds do not sprout, the time can also be extended. The grafting methods are: split grafting, cutting grafting and bud grafting.

Cleavage is often used for thick branches. First split the joint with a cleavage knife or axe, insert the wood in the center of the split, cut the scion by about 10 cm, cut the base into a wedge, and insert it into the split to align the outer cambium with each other. Each split can be grafted with a scion on each side. After that, gently pull out the wooden pole. The cutting is to cut a knife longitudinally with xylem at the interface, cut the scion to about 5 cm, and cut both sides of the base into one long and one short (the long side is about 3 cm and the short side is about 1. 5 cm), insert the short face outward into the incision and align it close to one end to form a layer.

Bud grafting is the use of bud grafting to fill the gap in the missing branches in the branch group, so as to make the branch group complete.

After the grafting is finished with the above methods, the interface should be tightly wrapped and tied up with plastic film strip immediately, and the scion should be exposed.

III. Post-grafting management

After the scion survived about 20 days after grafting, the leaves could be unfolded. Be careful to remove the sprouts from the rootstock in time. If it does not survive, the summer bud grafting should be carried out in the right place on the rootstock. When the new tip of the scion is 50 cm long, it can be coring to increase branches and form a crown as soon as possible.

How should purple magnolia breed? Propagation methods of Magnolia mandshurica

[FAQ] how should Magnolia reproduce?

[expert answer] Magnolia is a famous ornamental flower and tree, which is very suitable for planting in front and back of the hall in classical garden. it can also be planted alone or scattered in a small courtyard, so it has high ornamental value. I believe many flower lovers want to know how purple magnolia breeds. In fact, the main propagation methods of Magnolia are sowing, grafting, cutting and so on. The breeding methods of Magnolia are introduced as follows.

First, sowing and reproduction

From September to October, the seeds of Magnolia mandshurica were sowed with picking and sowing in warm water of about 50 ℃ before sowing, sowing in ditches and strips, and fertile sandy loam was selected for seedling sowing. After sowing, the soil was covered with 2 cm soil, watered thoroughly, covered with grass, and often kept moist. Generally, the seedlings could emerge after about 2 months, and the soil could be divided after thawing in the following spring.

2. Grafting propagation

Magnolia should be grafted with 2 ~ 3-year-old Magnolia seedlings as rootstock, bud grafting from July to August and cutting in autumn. After cutting, the scion should be covered with soil, and the soil should be removed in the late spring of the next year. It can also be cut and grafted in the greenhouse, and then stored in wet sand. After the graft is healed, it will be transplanted before germination in the following spring.

3. Cutting propagation

Before cutting, the cuttings were stained with rooting powder or soaked in 25ppm's Tsai acetic acid solution for 20 hours, which could promote rooting and improve the survival rate. The cuttings were collected from the one-year-old branches of the mother plant of Magnolia Magnolia. The cuttings were 15 cm long and 2 leaves were retained at the upper end.

IV. Ordinary pressing strip

The ordinary striping had better be carried out in February to March, cut the base of the branch to be pressed into half the depth, cut a section upward, and then stick a tile in the middle, then gently press it into the soil without breaking it, insert it into the soil with "U"-shaped thick iron wire, fix it to prevent it from warping, and then pile it on the soil, and in spring the strips can be cut off and planted after sending out root buds.

Fifth, high branch pressing

Before sinking, select strong and disease-free twigs (1.5 cm in diameter) on the mother plant, cut the cracks in the lower part of the basin fork, then cover them with bamboo tubes or bottomless tile pots, fill them with culture soil, tie them tightly with string on the outside, be careful not to touch them, often spray a small amount of water, keep them moist, and grow new roots around May of the following year.

[conclusion] Magnolia lanceolata likes light, high dryness and fat, so it should be paid special attention in the process of breeding. The breeding method of Magnolia is introduced in the above, and I hope it will be helpful to you!
