How do magnolia reproduce? Introduction to several propagation methods of magnolia

Magnolia, also known as Magnolia, Magnolia, etc., is a famous ornamental plant and traditional flower of Magnoliaceae. It is native to the provinces in central China. It is very sensitive to temperature and has a certain resistance to low temperature. It can survive the winter safely under a 20C condition. The main propagation methods are sowing reproduction, grafting reproduction, cutting propagation and striping reproduction. Let's take a look!

Magnolia magnolia sowing and propagation

Magnolia is the most suitable for autumn sowing. When the seeds mature from September to October, they can also be sowed in March-April of the following spring. Soak the seeds with warm water of about 50 ℃ before sowing, remove the waxy layer outside the seeds and remove the waxy layer, which can be rubbed with sand or soaked in 0.5% alkali water or plant ash water for 1-2 days. After sowing, cover 2 cm of soil, water thoroughly, cover grass, and often keep the soil moist. Generally, seedlings can emerge after about 2 months. Shade is needed in summer, anti-freezing in winter, and separate planting after soil thawing in the following spring.

Grafting propagation of Magnolia

Grafting propagation is the most commonly used method for propagation of Magnolia. It can not only maintain the quality of excellent varieties, but also blossom 2-3 years earlier than seedlings. 2-3-year-old Magnolia seedlings should be selected as rootstocks during grafting, and budding should be carried out from July to August. Cutting is carried out 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 (autumn or winter), and then stored in wet sand. After the graft is healed, it will be transplanted before germination in the following spring.

Cutting propagation of Magnolia

Magnolia is not easy to take root and has a low survival rate, so this method of propagation is rarely used. However, if the base of the cuttings is stained with rooting powder or soaked in 25ppm's Tsai acetic acid solution for 20 hours before cutting, it can promote rooting and improve the survival rate. Cutting in June-July, cuttings are collected from the annual branches of Magnolia magnolia mother plant. The cuttings are 15 cm long and 2 leaves are reserved at the upper end. After cutting, we should pay attention to shading, watering, and often keep the soil moist.

Magnolia striping propagation

Magnolia crimping propagation is also used in more ways of reproduction, mainly divided into ordinary striping and high branch crimping.

1. Ordinary striping: ordinary striping is best carried out in February-March, cut the base of the branch to be taken into half the depth, then 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, prevent it from warping, then pile it on the soil, press it in spring, and cut it apart after sending out root buds.

2. High branch pressing: select strong and disease-free twigs (1.5-2 cm in diameter) on the mother plant before entering, cut the cracks in the lower part of the basin fork, then cover them with bamboo tube or bottomless tile pot, 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.

Several common methods for the reproduction of Magnolia magnolia and the introduction of the matters needing attention in its reproduction.

When it comes to magnolia, I believe we are no stranger. Magnolia is a common woody plant, which is loved by many flower friends because of its beautiful color and charming fragrance. So, do you know how magnolia propagates? What are the points for attention in its reproduction? Today, the editor will give you a detailed introduction.

Grafting propagation of white orchids:

White orchids are often propagated by grafting. Generally, magnolia and yellow orchids are used as rootstocks. In June, the branches of white orchids can be grafted on the branches of magnolia and yellow orchids. Their incisions are 3-5 cm long and are tied tightly with plastic strips after joining. After about 3 months, the rootstock basically grows with the scion, which can be cut off from the mother plant and remove the upper part of the rootstock. It becomes a new plant.

White orchid striping propagation:

White orchid striping propagation is also used in more ways of reproduction, mainly divided into ordinary striping and high branch crimping.

1. Ordinary pressing: the ordinary pressing is best carried out in February to March, cut the base of the branch to be pressed into half the depth, then 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 wire, fix it, prevent it from warping, and then pile it on the soil. After the root bud is sent out, the strip can be cut off and planted in spring.

2. High branch pressing: select strong and disease-free twigs (1.5-2 cm in diameter) on the mother plant before entering, cut the cracks in the lower part of the basin fork, then cover them with bamboo tube or bottomless tile pot, 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.

Magnolia magnolia sows and propagates:

Sowing and raising seedlings at the end of September or early October, harvest the ripe fruit, take out the seeds, soak them in ash water for 2 days, then scrub the waxy aril and rinse them with clean water to sow the seeds; you can also wash the seeds and refrigerate them with the wet sand stratification method, otherwise it is easy to lose the seed germination ability. It was sown in the indoor pot in March of the following year, and the seedlings could emerge in about 20 days.

Cutting propagation of white orchid:

White orchids can also be propagated by cutting, but the ability of reproduction and regeneration of white orchids is poor, and it is not easy to root and survive by cutting, so most of them are not adopted. There are more ways of propagation of white orchids, more grafting and striping are used, while sowing and cutting are less used, but for family breeding, grafting and striping are enough.

The trunk of the big tree of seed origin is often obvious, the tree body is sturdy, majestic and majestic, the growth is strong, the node long branch is sparse, but the flower quantity is a little sparse.

Grafted species often show multi-stem or trunk low-branched characteristics, short branches are dense, the tree is relatively small, but the flowers are colorful, the distant view is flawless and enchanting. Therefore, Magnolia landscapes of different origins have different tastes in the application. In small or closed gardens, grafting species should be used to reflect the interest of antiquity, while real species should be selected in scenic spots to show the rough and simple style.

Huang Magnolia

Magnolia belongs to Magnoliaceae, deciduous shrubs. It is a very precious ornamental plant. The flowers of Magnolia are mostly white, pink and purplish red. Yellow magnolia is extremely rare. Magnolia blossoms at the end of spring.

The growth environment is positive to semi-negative, and the soil is a general garden soil with good drainage and no need for pruning. It can be planted in both north and south. Magnolia flowers are golden and bloom late, so there is no need to worry about the harm of frost in early spring.

Second Qiao Magnolia

Magnolia plants of the family Magnoliaceae. Also known as cinnabar magnolia, purple magnolia. It is a hybrid of Magnolia Magnolia and Magnolia magnolia, which was bred in 1840 by 1820 Murray. Morphological features: deciduous small trees, high 6--l0 meters. Branchlets glabrous. Leaves Obovate, apex shortly acute, midvein base often hairy, abaxially more or less pilose, petiole pilose, stipules 1/3 of petiole.

The first leaves of the flowers are open, the flowers are large bell-shaped, purple or red, white and fragrant inside, with 9 tepals. Fruit black, with white lenticels, seeds dark brown. The flowering period is 2mi-March, and the ripening stage is 9m-October.

Ecological habits: positive trees, slightly shady, the most suitable to grow in acidic, fertile and well-drained soil, slightly alkaline soil can also grow. Like fat, fleshy roots can not tolerate stagnant water. Like moist air, strong cold resistance, sensitive to temperature. I can't stand pruning. The life span can reach more than a thousand years. Seedling cultivation: mainly by grafting propagation, can also be used to strip, cutting propagation. Greening uses: Magnolia is an excellent ornamental tree species.

Red magnolia

The new variety selected by Magnoliaceae New Variety Research Institute blossoms three times a year in spring, summer and autumn. In China, there are few flowers in midsummer and even fewer woody flowers and trees. This variety meets the needs of this period of time very well. Magnolia can be planted alone or in groups in the garden, and now it tends to be used in street trees.

The key points of Magnolia cultivation are like light, fertilizer and water, and are afraid of stagnant water and rotten roots. The position should be raised when planting in the southern lowland. In the alkaline land with a pH value of 7.5-8.3 in the north, 3 ‰ ferrous sulfate solution can be neutralized 3-4 times a year. As the new root of Magnoliaceae is fleshy root, the wound heals slowly and needs careful management after transplanting.

From ancient times to the present, Magnolia is a flower plant with high value. From the above introduction, we can see that its value is mainly reflected in landscaping and food. Magnolia has a beautiful appearance, so it is not too much to be an ornamental plant in the garden.

In addition, Magnolia is also rich in vitamins, amino acids and other trace elements, which has the effect of dispelling wind-cold, ventilating and regulating the lung. Magnolia as an ingredient, making magnolia cake, magnolia salad, magnolia corn porridge and so on are all good delicacies.
