The female flower is a deciduous tree of the genus Magnolia. The branches are long and glabrous, and the branchlets and buds are pilose. Leaves broadly elliptic or obovate-oblong, 6 to 15 cm long, with white powder on leaf blade, lateral veins 6 to 8 pairs. The flowers are white, aromatic, single-branched, with long stalks. When in full bloom, they are wafting with the wind. They are fragrant and fragrant. The flowering period is from early June to mid-July, and the fruit ripening period is mid-September. Sexual cool and moist climate and fertile soil, propagation methods commonly used cuttings, sowing, but also grafting, ramets.

First, cutting cuttings Select the current year's shoots, 12 to 15 cm long, full of buds, cut the top 2 to 3 leaves cut half, remove the lower leaves. The cutting depth is 4 to 5 cm (ie, 1/3 of the length of the cutting), and watering is performed after plugging to make the cutting and the substrate tightly bound. Insert the bed with a plastic film, keep the humidity inside the inserter, water it 2 or 3 times a day, and root it for 50 to 60 days.

Second, sowing 1, seed treatment Seeds in the sand in mid-November, to the middle of March the following year began to warm the germination, the temperature should be 10 to 25 degrees Celsius, beginning in mid-April, germination, after mid-April the germination rate can reach 72 %. 2. Sowing the soil for soil preparation, so that the surface is filled with water. After the water is left behind, the water is used for seeding. The spacing is 25 centimeters, the seed distance is 3 centimeters, and the cover soil thickness is 1.5 centimeters. After the film is covered, the film is moistened to prevent heat. Seedling damage. 3. Seedling management at the initial stage of emergence, in order to accelerate germination, windproof frost, and anti-flooring. In the middle and late May, the height of the seedlings can reach 1 cm, and a leaf begins to be shaded at this time to prevent sunburn. In order to prevent the occurrence of leaf spot and yellow seedlings, carbendazim can be sprayed and fertilized in appropriate amounts. In addition, weeds should be rigged and irrigation must be timely. Through the comparison of shading and total light, it was proved that the shading seedlings have a relatively large blade and a large growth. Slow growth throughout the summer. In early September, as the sun weakened, the weather gradually cooled and the shade was removed. Seedlings are as high as 4 to 5 cm at this time and grow 4 to 5 leaves. The seedlings grow strong. In late October, the seedlings defoliated, they stopped growing, the winter was cold, and fertilization and irrigation were stopped.
