How do magnolia stems branch? The cultivation method of magnolia

The branching method of the magnolia stem is racemes. That is, there is a branch on a knot.

Magnolia, also known as magnolia, is a deciduous tree species of the genus Magnolia in the family Magnoliaceae. Its appearance is characterized by an ovate or spherical crown, with hairy shoots and buds; The leaves are single alternate, obovate-oblong; The flowers are large, about 10 cm in diameter, pure white, aromatic, calyx and petals are similar, a 9-piece, blooming before the leaves in March and April.

Magnolia is a common garden ornamental tree species in China. It is suitable for row planting or ornamental planting. The petals are edible, the seeds can be pressed for oil, and the bark and flower buds are medicinal.

1. Cuttings.

Cuttings are one of the methods of many flower propagation, mainly because the operation of cuttings is relatively simple, and the survival rate is not low, so it is deeply loved by the majority of flower friends. But on the white orchid plant is the least favored method of propagation, because of the white magnolia.

The self-regeneration ability is relatively poor, and the rooting ability of its branches is not strong, so the survival rate of cuttings will be very low, so it is not recommended for flower friends.

2. Grafting.

Grafting method is one of the most technical tests among the four breeding methods, and there are many kinds of breeding methods, and most flower friends use two kinds of grafting and cutting. Docking refers to the time of connection, spring, summer and autumn three seasons are the growth period of magnolia, in these three seasons can be used to rely on the propagation method, the branch part of the grafting is generally about 60 centimeters from the ground is the best, tie the mud ball on it, and wrap the outside of the soil with leaves, this is for the rain to wash the soil away. After the completion of the pick-up work, the general management time is two months, and it can be cut off after two months.

3. Sowing. The preparation of the sowing method is more, in September you can start to prepare to collect the seeds, the collected seeds should be washed with water and then go out of the false skin on the surface, and then the seeds are kept in the moist sediment, so the preservation method is to prevent the seeds from losing their activity, and they can be taken out and sown in March of the next year, and the cultivation time is generally about half a month to grow small seedlings.

Fourth, the strip.

There are also many methods of strip propagation method of magnolia, and the most commonly used are ordinary strips and high branch strips.

1.The best time for ordinary striping is from February to March, when the branches to be pressed are treated, split at the base of the branches, and can be stuck with something thicker in the middle, and then slowly pressed into the soil, being careful not to break the branches. The branches pressed into the soil need to be held in place with some filaments so that the separated branches do not warp out.

Wait for the shoots to sprout and then divide and cultivate. 2.The high branch strip is selected to grow robustly on the magnolia plant, and is not threatened by pests and diseases, but there are some cracks in its pot, and it is also necessary to use some auxiliary tools to fix the branches, but the high branch strip is covered with some cylinders or clay pots and other things, filled with soil in it, and the humidity is maintained daily, and new shoots can germinate in May.

The branching method of Magnolia Jing is to propagate directly by cuttings, and some small branches can be taken down and propagated by cuttings.

Uniaxial branching. Young forest management.

Weeding and weeding. Weeds and weeds grow rapidly, competing with newly planted seedlings for growth space and fertilizer water, and only by removing weeds and weeds in time can magnolia seedlings grow normally. Removal of weeds and weeds should be carried out 2 3 times within 1 year.

Chemicals can be used to control weeds, usually paraquat and glyphosate. Mechanical weeding can also be carried out, even with a brush cutter, which is highly effective and conserves soil and water. In addition, manual hoeing can also be used, i.e. a shallow hoe is taken within the canopy projection range to avoid damage to the roots.

Fertilize. After the magnolia seedlings survive, the root system stretches outward, and a small amount of nitrogen fertilizer is applied when the new leaves of the seedlings grow and the new shoots are drawn, which can promote the rapid growth of the seedlings. Top dressing was applied with 25 30 g of urea, or 30 40 g of trim nitrogen, phosphorus and potassium compound fertilizer per plant, and irrigated with chemical water or sprinkled in rainy days.

Top dressing can be carried out 1 2 times depending on the growth of the sapling. Due to the fast growth rate and strong assimilation of magnolia trees, a large number of flowers at the beginning of the year and a large number of leaves in autumn, they need to be supplemented with fertility, especially phosphate fertilizer. The fertilization of magnolia trees in cultivation is generally based on basal fertilizer, which is applied in autumn and winter in combination with woodland management.

Two-year-old saplings were treated with 10% superphosphate plus 90% chicken manure 2 3 kg plants and 50 100 g of nitrogen, phosphorus and potassium compound fertilizer, which increased year by year with the growth of the trees.

The pile is shrunk and dried. After magnolia planting, the seedlings are skewed and lodging due to lodging due to external forces or the leafy branches and leaves are lush during the growth process, which will lead to the bending of the main trunk. Therefore, it is necessary to nail the stump and shrink the trunk to keep the seedling growing upright, or to make the trunk grow upright by tying and shrinking the trunk.

Drying and pruning. According to the purpose of cultivation, the stem used for road greening should be set to more than 2 m; Gardens and courtyard planting, in m. Magnolia has strong internode germination, and new branches continue to sprout at the base and internodes of the main trunk, which should be pruned in time.

In order to promote the growth of side branches, the fast-growing main branches were retracted and pruned, and the partial crown trees were pulled to maintain the uniform growth of the crown. In order to increase the amount of magnolia flowering, it is also necessary to pay attention to cutting off the inner branches, weak branches, and retaining the beautiful crown.

1. Soil. Magnolia grows well in sandy loam soils, the soil is thick and loose, humus is abundant, and drains well.

2. Temperature. Magnolia is hardy but not hot and dry, with an average temperature of 16. It is resistant to low temperatures and can withstand extreme minimum temperatures of -12. Most of the north can spend the winter outdoors normally.

3. Watering water.

Because the sandy loam soil with strong permeability is used, it should be watered immediately after drying, and the soil should not be too dry. Remember not to accumulate too much water, otherwise root rot is prone to occur.

Fourth, fertilization. During the growing period, you can add some thin fertilizer, mainly organic fertilizer. If conditions permit, deep application of ammonium bicarbonate in the soil can promote the growth of magnolia and reduce the occurrence of pests and diseases.

5. Illumination. Huangsan magnolia is shade-tolerant when it is young and does not have high requirements for light. When it grows up, it can receive normal light. Don't worry about outdoor planting, the daily sunlight can meet the growth needs.

Sixth, pay attention to the good items of the matter.

1.Repotting: Because it is a small tree and the root system is very developed, it is recommended to use a larger pot, which is conducive to the growth of the tree and enhances the overall beauty.

2.Trim: You can trim the shape and branch state to your liking.

A small amount of pruning can be done during its growth and development.

Magnolia belongs to dicots and is therefore a straight root system.

The straight root system is found in dicots, which is characterized by a distinct and well-developed taproot with a vertical downward orientation, and the lateral roots are grape-like around the taproot. Generally, the straight root system penetrates deep into the soil, and its lateral roots extend widely in the soil, and the root system of woody plants can reach 10 18 meters in diameter, often exceeding several times the canopy; Camel spines that live in desert areas can go up to 20 meters underground to absorb groundwater.

Magnolia belongs to dicots and is therefore a straight root system.

Magnolia flowers prefer warm, sunny, moist and well-drained places, requiring fertile soil and no stagnant water. It is hardy and can safely overwinter at 20 years. It grows well in places with a good microenvironment in Beijing.

In the south, where temperatures are warmer, it blooms from December to January.

Transplanting should be carried out more than ten days before germination, or before the leaf development after flowering. It generally takes about 5 years for seedlings to bloom. There are also two Qiao magnolia common in the north, with petals that are lilac on the outside and white on the inside.

Magnolia flowers are more resistant to harmful gases. If this flower is planted in a factory contaminated with sulfur dioxide and chlorine, it has a certain resistance and sulfur absorption ability.

Magnolia flowers are as white as jade, fragrant as orchids, can be more than 10 meters high, and the crown is ovate. The large leaves are obovate, the apex short and acute, the base wedge-shaped, the surface shiny, the whole margin, the stalk, the young branches and buds are covered with short hairs, and the winter buds have large scales. The flowers bloom before the leaves, apical, large, 12-15 cm in diameter.

The perianth is 9-pointed, bell-shaped. Ears cylindrical, brown; The fruit is cracked when ripe and is red.

It is suitable for growing in warm and humid climates and fertile and loose soils, and likes light. It is not tolerant to drought or waterlogging, and the roots die after 2-3 days of flooding. It is sensitive to toxic gases such as sulfur dioxide and chlorine, and has poor resistance.

Roll down the shoots of the magnolia to the ground and cover the soil. 3. Pruning and transplanting: cut off the rooting branches of the magnolia and transplant them into fertile soil.

4. Top dressing: Magnolia planting needs to be topdressed once a week to make it grow vigorously.

1. Breeding time

The best breeding time for magnolia is in March and April in spring or August and September in autumn every year, because the temperature at this time can be stable at more than 15 degrees, and the light time and humidity are more suitable, which is conducive to improving the survival rate of white magnolia and making it take root and germinate quickly.

2. Strip propagation

Magnolia is usually not fruitful, and is mostly propagated by pressing strips, when propagating magnolias, it is necessary to select erect and strong branches of the year to press down on the ground, and then cover a layer of soil for compaction, and to peel the magnolia branches 5-6 cm from the base.

3. Pruning and transplanting

When cultivating magnolias, it is necessary to cut them off with sterilized sharp scissors after the branches of the plant have taken root, and then transplant the rooted branches of the magnolia into the soil, and apply well-rotted organic fertilizer or cake fertilizer to the soil to provide the nutrients needed for the growth of the magnolia.

4. Top dressing fertilizer

Magnolia needs sufficient nutrients in the growth process, when breeding magnolia, it needs to be planted for a week, and then apply a thin liquid fertilizer to it, so that the growth rate of magnolia is accelerated, and urea needs to be applied every month in the peak growth season of magnolia to make it bloom quickly.

Magnolia is a dicot plant with a straight root system, which is characterized by a well-developed taproot and a grape-like distribution of lateral roots around it, with a wide range of extensions. Therefore, the depth of the pots used for potting should be at least 30-40 cm, so that the roots can grow normally. During the growing season, it is necessary to keep watering and apply well-rotted organic fertilizer, which can generally be applied twice a month, so that the root system can get more nutrients and promote growth.

Magnolia is a dicot plant with a straight root system, which is characterized by a well-developed taproot and a grape-like distribution of lateral roots around it, with a wide range of extensions.

Does the magnolia root system destroy the wall.

The root system of the magnolia is not large, and it may cause serious damage when planting, so you need to pay attention to it when planting.

Magnolia roots are generally deep.

The root system of magnolia is relatively developed, the deep rooting ability is strong, and it belongs to the straight root system, and the root system of woody plants can extend up to 10 18 meters in diameter in the soil.

Magnolia is suitable for growing pots.

Because the root system of magnolia is relatively developed, the pots used for potting plants should not be too shallow, at least 25-35 cm deep, and the orange shade ensures that the roots can grow normally.

Treatment method for underdeveloped root system of magnolia.

White orchid is a fleshy root, the root system is underdeveloped and difficult to grow, and the soil needs to be kept slightly moist during the growth and flowering period. Apply well-rotted organic fertilizer, which can generally be applied twice a month, so that the root system can get more nutrients and promote growth.

Magnolia (magnolia denudata) is a deciduous tree of the Magnoliaceae family. Its flowers are white and fragrant, and they are traditional early spring flowers and trees in our country. Likes light, prefers warm and humid climate; Fleshy roots, prefer fertile, moist and well-drained slightly acidic sandy loam; Avoid waterlogging, poor growth in clayey soil.

It can be propagated by sowing, cuttings, grafting and stripping.

1) Sowing method.

The outer seed coat of magnolia is oily and perishable, and it is not suitable for long-term storage, so it is better to sow it immediately after harvest, or remove the outer seed coat and sow it in the following year after sand storage. Seedlings prefer shade and need to be covered in winter in the north.

2) Cuttings.

It can be used for cuttings in summer, and it takes root after about two months, and the survival rate is generally not high. Heel-shaped cuttings can also be used to promote rooting. Hard cuttings are generally difficult to root.

3) Grafting method.

Magnolia is often used as rootstock. In the northern region, the square budding method can be used in early to mid-August; It can also be cut in late September, and the scion will be covered with soil after grafting, and removed after the spring of the following year, and grafting is generally avoided in early spring; The method of relying on the grafting method is easier to survive than the cutting method, but the growth potential is not as vigorous as the cutting method. It can be carried out in 4 July, and can be cut from the mother plant after about 50 days, but it is reliable to take a longer time.

4) Strip method.

Spring striping can be carried out under the low shrub-like mother plant, and it can be separated from the mother plant after about 1 2 years. High-altitude striping can also be carried out in humid places in the southern climate.

Magnolia is not resistant to transplantation, and in the north it is not suitable for transplantation in late autumn or winter. Generally, it is better to do it before flowering or after flowering and just spreading the leaves in spring; Autumn is the best time to be mid-autumn, and too late will cause the root system to heal slowly. When transplanting, soil should be bringed, and appropriate budding or leaf cutting should be carried out to avoid excessive water loss during transpiration.

Petioles should be left when cutting leaves to protect young shoots. Surviving seedlings are ready to emerge after 4 to 5 years of nursery culture.
