Potting and medicinal use of magnolia

Magnolia is a deciduous shrub of the genus Magnolia in the family of Magnoliaceae, with a height of 3 to 5 meters in the ground, and a height of 1 to 1.5 meters in pots. It is often clustered, with leaves that are obovate or elliptic, and flowers that are solitary at the tops of the branches, campanulate, and with a perianth of 9 pieces, 3 pieces in a round, purple or purple-red, and in spring, the first flower is followed by a leaf or a flower and leaf are put together.

Magnolia can be planted in the ground, but also suitable for pot planting. Potting points are as follows:

Potting soil

Magnolia likes loose and fertile acidic, slightly acidic soil, can be used to mix the amount of rotting soil and garden soil for culture soil, and add 50 to 150 grams of bone meal or nitrogen-phosphorus-potassium composite fertilizer in the soil. Pots should be slightly deeper and larger, the bottom of the pot to put some broken hard plastic foam block, enhance air permeability and drainage, and prevent root rot. Every year or every other year in the flower after turning pots to change the soil, retaining 1/2 to 1 / 3 of the soil.

Water and fertilizer

Magnolia like moist, afraid of waterlogging, so timely and appropriate amount of watering is very important. Spring to flowering, the potting soil to keep moist but not wet; after flowering potting soil to keep moist but not waterlogged; after leaf fall potting soil to keep slightly moist but not dry can be. No drought or waterlogging at any time, especially in the rainy season to pay attention to drainage and flooding.

Magnolia likes fertilizer, fertilizer to seize the two key moments before the flower in February and after the flower in May, ten days or so a nitrogen, phosphorus and potassium fertilizer, the former so that the buds expand, flowers open, the latter to promote more pregnant buds, the following spring flowers. Winter leaf drop when the application of a phosphorus and potassium-based fertilizer, to enhance its ability to resist the cold over winter, the rest of the time less or no application. Avoid single application of nitrogen fertilizer.

Light and temperature

Magnolia likes light, placed in the sunny courtyard, roof garden, see more sunlight growth robust and luxuriant, semi-shady conditions can also grow, but thinner and fewer flowers, overshade is flowerless. It is hardy, Beijing and its south can be outdoor overwintering.

Pruning

The roots of magnolia have strong sprouting power, such as the need for propagation, cut as long as possible, keep three trunks per pot can. For too high and too long branches, can be cut short just after the flower leaf spreading, because of its poor ability to heal, after cutting to apply sulfur powder antiseptic, if not necessary, do not prune. After flowering, if you don't need to keep the seed propagation, you should cut off the residual flowers with the tip.

Propagation

Commonly used method of dividing the plant, combined with the pot after the flowering of the soil, will be poured out of the plant, with a sharp scissors or knife to the roots of the tiller of the plant with the roots cut off, another planting can be.

Medicinal

Magnolia is not only big and beautiful flowers, graceful, fragrant, high ornamental value, few pests and diseases, and its flower buds named Xinyi, has always been the main medicine of Chinese medicine to treat nasal diseases, picked before the flower buds, and placed in a well-ventilated place in the shade to dry. Li Shizhen in the "Compendium of Materia Medica" on its efficacy in the treatment of nasal disease made a positive statement. Modern research has proved that the volatile oil contained in Xinyi has a constricting effect on the blood vessels of the nasal mucosa and can promote the absorption of secretions, thus improving the function of nostril ventilation. Treatment of acute and chronic rhinitis, sinusitis, can be taken Xinyi, Cang Erzi 10 grams each, with gauze bag decoction, take its concentrated juice nose drops, 3, 4 times a day, the efficacy of good.

Magnolia is a deciduous tree, up to 25 meters high, diameter thickness of up to 200 centimeters, the crown is narrowly ovate when young, mature large trees are broadly ovate or loose broadly ovate. The solid origin of the tree is often the main trunk obvious, the tree is strong, majestic, strong growth potential, section long branch sparse, but the amount of flowers is a little sparse. Grafted species are often multi-stemmed or low-branching main stem-like features, short branches, dense, small tree, but the flower clusters, white from a distance, enchanting. Therefore, different origins of magnolia garden applications in different interests, in small or closed gardens, lone planting or small pieces of bush planting, grafting is appropriate to reflect the interest of the ancient and elegant; and scenic areas are appropriate to use the live species to show the rugged simplicity of the style.

The bark of the tree is grayish-white and smooth and less cracked when young, and dark gray and rough and cracked when old. The branchlets are gray-brown. The terminal buds and pedicels are densely covered with gray-yellow long Juan hairs, fluffy as a young mouse hibernation, winter state is more obvious. Branching habit with the age of the tree is different, young single bud extension, so the main trunk is obvious, the crown is regular, and after the flower, leafy branches mixed buds in the fruiting spike after the double branch or multiple branch extension, lateral development is more prevalent than the straight in the growth, so the crown to the direction of the development of broadly ovate.

Leaf blade alternate and sometimes spiral, broadly obovate to obovate, 10-18 centimeters long, 6-12 centimeters wide, apex rounded and broad, truncated or slightly concave, with a short cusp, so it is also known as the convex head of the magnolia; below the middle of the tapering cuneate, entire. Magnolia leaves at the base usually have stipules or appendages, stipules are of two kinds, the stipules at the end of the buds at the end of the branches are adnate to the young stems and the petiole is separated and is imbricated; the stipules in the leaf part are scattered, tile knife-like, adhering to the base of the petiole on both sides, the buds reach out to the leaves for a long time, the stipulates are detached, and the residual annular stipulate scars are found on the young branches, which is the identifying feature for the species of the Magnoliaceae.
