Habits: Magnolia is a deciduous tree, up to 25 meters in diameter, up to 200 cm in diameter, canopy narrow egg-shaped when young, mature trees are broadly ovoid or loose wide oval. The tree of the origin of the actual life is often the main trunk. The tree is sturdy and magnificent. It grows strong, and the length of the branch is sparse, but the amount of flowers is slightly dilute. Marriage inoculation tends to be characterized by multiple stems or trunks with low branching characteristics. Branches are short and branches are dense and the trees are small and clever, but the flowers are luxuriant and distant. Therefore, different origins of the Magnolia Garden in the application of different tastes, in small or closed gardens, solitary planting or small pieces of planting, should be used to inoculate, in order to reflect the quaint interest; and scenic resorts should choose real species, To express rough and simple style. When the young, the bark is grayish white, less smooth and cracked, and when old, it is dark gray and cracks rough. Branchlets grayish brown. The end buds and pedicels are densely covered with gray-yellow long hairs, fluffy hair like young rats dormant, and winters are more prominent. Branching habits differ with the age of the tree. When young, single shoots extend, so the trunk is obvious, and the crown is regular. After the flower is seen, the mixed shoots of the leaf shoots are double-branched or multi-branched in the ear, and the lateral development is prosperous in the straight growth. The crown develops in the direction of a wide oval. Leaves alternately sometimes spirally, broadly obovate to obovate, 10-18 cm long, 6-12 cm wide, apex rounded, truncate or dimpled, with short tips, it is also known as convex magnolia; Wedge, whole. Magnolia leaves usually have stipules or appendages at the base. There are two kinds of stipules. The stipules at the end of shoot buds are borne on the young stems and separated from the petiole to form imbricate. The stipules of the leaves are scattered, wattles and sticky. On both sides of the base of the petiole, the shoots stretched and the stipules fell off. The stipules remained on the young shoots. This was the distinguishing feature of the Magnoliaceae species.
Features: Flowers open, top, erect branches, bell-shaped, in full bloom, such as jade dish, diameter 10-16 cm; perianth 9 pieces, occasionally 12-15 pieces, even more than 30 pieces, inverted oval, Jade white, sometimes basally with blush; filaments purple-red; gynoecium pale green, glabrous. Pollen grains are long and elliptical, such as a leaf boat. The equatorial view is olive-shaped and its size is 46.6*20 (microns). With a single groove, left and right symmetry; the outer wall surface has a fine fine mesh glyph, the mesh is small and not obvious, the ridges are fuzzy. Aggregate fruit cylindrical, green, turning reddish-brown when mature, length 12-15 cm, diameter 3-5 cm, giant sometimes up to 25 cm, weighing 250 g; Usually part of the carpels are inconsistent and inflexible, and the cultivars are often infertile. When the single fruit matures, there are drooping rosacea, weak red fruit, swaying in the wind, and it lasts for a long time. The seeds are heart-shaped or irregular polyhedron, about 9 in length. Millimeters, width of about 6 mm, seed coat can be divided into three layers from the outside to the inside, the outermost is a leathery layer, bright red or pink, very smooth, usually called aril. The middle layer is fleshy, creamy, and has a greasy feel. The inner layer is a hard inner seed coat. It is yellow-brown when it is immature and dark and shiny when it is too ripe. The red outer seed coat and the oily fleshy mid seed coat are all intended to attract insects and birds for feeding, in order to facilitate the spread and germination of the seeds. The hard inner seed coat can protect the young life from harm before germination. There is a special structure of the seed coat in the seed coat of Magnolia magnolia. It is a simple bead hole formed by the introgression of the seed coat inward. This structure is an important feature distinguishing the species of Magnolia from other species. However, the magnolia genus is mostly similar in shape, shape and quality. Even if it is of the same Magnolia species, its origin is different, and its seed age is not the same.
Cultivation points: Magnolia blossoms in March. After flowering (in late May), the aggregated fruits swell and become sturdy. In August, the physiology matured. In the middle and late September, the fruit was hardened, turned red, cracked, opened, and the single seed was suspended. Naturally mature. The grain weight of seeds is about 146 g, the rate of outgrowth of polymer fruit is about 10%, and the seed germination rate is 20.7%-97%. Seedlings, sprouted on excavation, 2 cotyledons, ovate near rhombic, increased with seedling growth, narrowed at upper and lower, base spurt into stem, entire margin slightly wrinkled, bilaterally unsymmetrical, yellow-green on top, abaxially The color is slightly lighter, the epicotyl length slightly longer, about 1-2 cm, young stems yellow-green, primary leaves alternate, the first leaf is oval, apex rounded, with a sharp tip, base wedge, petiole length 6-9 mm, with two The stipules, leaving the stipules on the petiole, leaving a ring-shaped mark on the stem, after the leaves are long oval gradually become normal leaf. The hypocotyl is cylindrical, the base is thick, and the major roots are well developed. The roots and necks produce 3-5 unequal lateral roots, pale yellow. The soil is rich in organic matter, and the moist soil is good. In open field cultivation, there are often shrubs with flourishing leaves and few flowers. It is necessary to stop the use of nitrogenous fertilizers, cut off long branches, apply twigs, make them dwarf, and increase trace fertilizers such as phosphorus and potassium. To promote flowering.
