Introduction of common propagation methods of Magnolia lanceolata

The second Arbor Magnolia is purplish red on the outside, and the length of the calyx is half the length of the petals. Some flower friends will not know the difference between it and Mulan. Erqiao Magnolia is a hybrid of Magnolia and Magnolia, and there are about 20 species in horticulture. Artificial propagation of Magnolia can be done by sowing, cutting, grafting, striping and tissue culture.

1. Sowing: the second Arbor orchid generally does not bear fruit, and a small amount of fruiting fruit ripens from September to October. Harvest the ripe fruit, dry it indoors for 1 to 2 days, remove the red seeds, pile them with fine sand or rub the red skin in water to dry in the shade, avoid the sun and do not lose water. It is appropriate to pick and sow or store in wet sand to sow from February to March of the following year, with a germination rate of 70% to 80%. The seedling of Magnolia mandshurica has good plant shape and is suitable for ground planting, but because it is a hybrid, the characters of its offspring are unstable and can not maintain all the habits of good varieties, so it is rarely used in the propagation of improved varieties, but it is often used in breeding new varieties.

2. Cutting: the cuttings of Magnolia mandshurica were carried out from May to July. Select the current year's branches of young trees as cuttings, leave a small amount of leaves in the upper part, soak the lower part of the branches in 50 mg / L indoleacetic acid, rooting powder or naphthylacetic acid for 6 hours, insert into wet sand or vermiculite bed, properly shade, and often spray moisturizing, the survival rate can reach about 70%.

3. Grafting: usually use their parent Magnolia (details) or Magnolia, this species or Huanglan, Magnolia, Magnolia and other plants of this genus as rootstocks, which can be used in many ways, such as split grafting, bud grafting, cutting grafting, abdominal grafting and so on, but the survival rate of split grafting and bud grafting is higher.

4. Striping: select well-growing plants, take 1-2-year-old branches with a diameter of 0.5 to 1.0 cm as strips, if there are branches, they can be pressed on the branches. The time of pressing is better from February to March, and it can take root in the same year after pressing. It can blossom from 2 to 3 years after planting.

5. Tissue culture: the tissue culture of Magnolia can maintain the excellent characters of its varieties, generally using terminal buds and lateral buds as explants, primary and subculture medium MS+3.0mg/L6-BA+0.2mg/LIBA, and rooting medium 1/2MS+0.5mg/LNAA.

The morphological characteristics and habits of Longnu Flower the function and reproductive mode of Longnu flower

Longnu flower, also known as Shangguan flower, the lost Chinese famous flower, belongs to the shrub or tree of Magnoliaceae, and is a precious ornamental flower. Produced in the mountainous areas of southwestern China, due to deforestation and excessive bark peeling, serious damage to resources, habitat deterioration, weak ability of natural regeneration, adult plants are unique, is a national protection of endangered rare plants.

Longnu flowers bloom in March of the lunar calendar every year, flowers and leaves open at the same time, drooping, the flowers are milky white, beautiful and fragrant. Pistil prominent, stamens dark purple.

Longnu flower bark, known as "Jiang Pu", is a substitute for Magnolia officinalis. It is a rare traditional Chinese medicine with definite efficacy and reliable therapeutic effect, such as dryness and dampness, resolving phlegm, relieving asthma, appetizer and relieving pain. it has an irreplaceable effect of other drugs.

Morphological characteristics of Longnu Flower

The dragon female flower is an evergreen shrub or small tree with obvious lenticels in the bark and purplish red branches in the current year. The leaves are elliptic-ovate or oblong-ovate, about 8 "long and 4" wide, shiny; the upper part is grayish yellow pilose along the midrib and lateral veins, and the lower part is densely silvery gray flat villous. Every year in March of the lunar calendar, the flowers and leaves open and droop at the same time, the flowers are milky white, the flowers are large and beautiful, the pistils are prominent, the stamens are dark purple, the petals bloom 12 petals every year, 13 petals bloom every year, and the petals increase or decrease naturally because of the year, which is very magical and has high ornamental value.

Longnu flower is a precious ornamental flower and tree, which grows from northwest and west of China to Ailao Mountain. It is born in coniferous and broad-leaved mixed forest at an altitude of 2700-3500 meters. It is a third-class national protected plant. After 15 years of unremitting efforts of flower workers in Dali Bai Autonomous Prefecture, Yunnan Province, Longnu Flower, a famous folk flower for hundreds of years, has been lost, and the historical situation of only hearing its name but not its flowers has ended. The first batch of living specimen seedlings of Longnu flower have been successfully bred, and Longnu flower will reappear in Dali.

Ecological habits of Longnu Flower

The dragon female flower is a subtropical tree species with a sexual preference for light. However, the young trees are quite tolerant to shade, like warm and humid climate, have a certain ability to tolerate drought, and can withstand short-term-19X low temperature without significant frostbite, but if the low temperature is-12x for a long time, the leaves will be frozen.

Longnu flower is a kind of acidic or neutral soil which is fertile, deep, moist and well drained. It grows poorly on dry, calcareous, alkaline soil and poorly drained clay. It has certain resistance to smoke and sulfur dioxide gas.

Longnu peanuts are in the mixed forest at an altitude of 1800 mi 2000 meters.

The mode of reproduction of dragon female flower

Longnu flowers are commonly used for grafting reproduction, striping reproduction, sowing reproduction, mainly sowing and grafting reproduction.

Sowing seeds

After seed collection in autumn, wet sand stratification can also be used to sow seeds in March of the following year and emergence in May. The growth of seedlings is slow, sowing should be denser and transplanted in the second year after sowing.

Grafting

From March to April, Magnolia and Magnolia were used as rootstocks. The scion selected the annual lateral top branches on the adult plants with many flowers, large flowers and thick leaves, removed leaves, grafted by splicing method, choked soil and top, plucked the soil after bud extension, and cut off the sprouting of rootstocks. There are also those who rely on biennial branches, which can be separated from the mother and grow independently after 1 ~ 2 months.

The function and use of Longnu Flower

Ornamental value

Dragon female petals milky white, usually 12 petals, leap years 13 petals, pistil such as dragon whisker-like protuberance, glittering and translucent; stamens deep purple and snow-white petals set off beautiful, sweet flowers, attractive honey smell. Leaf appreciation is "two and a half inches long, half wide, green and bright", while flowers are "Tingting Yan like this", "Luzhou incense", "stamens are big and fragrant". With the successful breeding of the first batch of live specimen seedlings of dragon female flowers, after orchids and camellias, another characteristic flower in Dali will trigger a new round of green wealth upgrading.

Function and use

The mysterious Cangshan dragon female flower quilt Dali flower worker skillfully inoculated down the mountain, identified by experts from Kunming Plant Research Institute of the Chinese Academy of Sciences, ended the chaotic era of this genus referring to deer as a horse. Dali Bai Autonomous Prefecture Flower Association Longnu Flower Research Group made an in-depth study of Longnu flower "high medicinal value, high cultural content, high ornamental value" conclusion.

How to breed magnolia with beauty and elegance

Magnolia is a very popular plant, beautiful and elegant. When planting magnolia, we should grasp the right time, neither too early nor too late. Today, the editor will give you a good introduction to the method of breeding magnolia, come and have a look!

Magnolia prefers fertilizer, but avoids big fertilizer; generally applying fertilizer twice during the growing period can be beneficial to flower bud differentiation and promote growth. Once in early spring, and again in May-June. Fertilizers are often made of fully mature organic manure. Newly planted seedlings do not need to be fertilized until after falling leaves or in the following spring. The root system of Magnolia is fleshy and can not tolerate stagnant water. It is advisable to keep the soil moist during the flowering and growing period. After entering the autumn, we should reduce watering, delay the rooting of magnolia, and promote the branches to mature in order to survive the winter. It is generally not watered in winter, but only once when the soil is too dry. Magnolia branch wound healing ability is poor, so generally do not prune. However, for the sake of reasonable tree shape, the overgrown branches, withered branches, disease and insect branches and branches that hinder the beauty of the tree shape should still be cut off at the initial stage of leaf expansion. In addition, after the flower fade, if there is no seed, the remnant flower and the ear of oyster should be cut off so as not to consume nutrients and affect the flowering in the coming year.

Magnolia is mostly planted in the ground, and it is appropriate to cultivate it into a pile when potted.

Magnolia can be propagated by grafting, striping, cutting, sowing and other methods, but the most commonly used are grafting and striping.

Magnolia prefers a sunny and humid environment and should not grow in alkaline soil for a long time. Planting should choose places with shelter from the wind and sun, good drainage and fertile places. There should be plenty of water and fertilizer before flowering to promote the fragrance of the flowers. Magnolia has few branches and generally does not need pruning except for withered branches, disease and insect branches and branches that disturb the tree shape. If there is no seed left after the flower fade, the fruit should be cut off so as not to consume nutrients. Magnolia has strong cold tolerance and can survive the winter in the open field in the south of North China and Northeast China.

Potted magnolia, feasible banding treatment, that is, after germination in April, with the growth of new shoots, banding at any time, tied into a curved posture, limiting the height of the trunk. And because Magnolia is a deep root system, living in the basin for a long time, it is easy to grow weak, so the main root should be repaired, planted in the field, and then put on the pot before flowering, so that the flowers can be numerous and colorful.

If you propagate with seeds, you must master the maturity of the seeds. When the seeds turn red and crack, they will be picked immediately. Early harvest will not sprout, and late harvest will be easy to fall off. The fruits with red outer seed coat were soaked in cold water and scrubbed except for clean seed coat. The seeds were dried and stored in layer sand. The seeds were sown from February to March the following year. The height of one-year-old seedlings was about 30 cm. Those who cultivate large seedlings are transplanted in the next spring, properly cut off the main root, re-apply base fertilizer, and control the density, the qualified seedlings with complete crown, rare buds and plant height of more than 3 meters can be cultivated in 3 to 5 years. After 2-3 years of planting, it can enter the full flowering stage. This kind of seedling has strong growth potential and strong adaptability, and its effect is not inferior to that of grafted seedlings.

Cutting is the main propagation method of Magnolia. The cutting time has a great influence on the survival rate, which is generally carried out from May to June, and the survival rate of young trees is the highest in the same year. Soaking the base with 50ppm naphthylacetic acid for 6 hours could increase the rooting rate.

Striping is a traditional breeding method, which is suitable for the preservation and development of famous and high-quality varieties. Purple magnolia is the most suitable to use this method, select well-growing plants, take 1 ~ 2-year-old branches with a diameter of 0.5 cm ~ 1 cm as strips, if there are branches, can be pressed on the branches. The time of striping is 2 ~ 3 months. After pressing, it took root in the same year, and the longer it was connected with the mother plant, the more developed the root system was and the higher the survival rate was. It can blossom in 2-3 years after planting.

In recent years, using the method of tissue culture, the buds of Magnolia were used as explants and cultured successfully in test tube. This method is of special significance in the preservation and development of new types bred by budding and hybridization.
