The genus is a deciduous small tree of the Magnolia family. The branches are slender and hairless, and the branches and buds are pilose. Leaves broadly elliptic or obovate-oblong, 6 to 15 cm long, with white powder on the back of the leaves, 6 to 8 pairs of lateral veins. The white aroma of the flower, the top of the single-branched branch, the flower handle is quite long, and it floats in the wind when it blooms. It is like a scent of flowers, so it is called the goddess flower. The flowering period is from early June to mid-July, and the fruit ripening period is mid-September. Sexually cool and humid climate and fertile soil, breeding methods are often used for cutting, sowing, grafting, and ramets. First, cutting The cuttings are selected from the same year, with 12 to 15 cm in length and full buds. Two to three leaves in the upper part of the cuttings are cut off and the lower leaves are removed. The cutting depth is 4 to 5 cm (ie 1/3 of the length of the cuttings), watering after insertion, and the cuttings and the substrate are tightly combined. The plastic bed is covered on the insertion bed, and the humidity in the insertion bed is maintained. Watering is carried out 2 to 3 times a day, and rooting can be carried out in 50 to 60 days. Second, sowing 1. Seed treatment. The seeds are sanded in mid-November and begin to warm and germination after mid-March of the next year. The temperature should be 10 to 25 degrees Celsius, and the germination begins in mid-April. The germination rate can reach 72% after mid-April. 2, sowing. The soil is loosened, the surface is smoothed, and the water is immersed. The water is sown, the spacing is 25 cm, the seed distance is 3 cm, and the thickness of the soil is 1.5 cm. After sowing, the film is covered to keep warm and moisturize to prevent seedlings from being damaged. 3. Seedling management. In the early stage of emergence, in order to accelerate germination, windproof frost and anti-floor knot. In mid-to-late May, the height of the seedlings can reach 1 cm, a leaf, and at this time, the shade begins to prevent daily burns. In order to prevent leaf spot and yellowing of seedlings, carbendazim can be sprayed and fertilized in moderation. In addition, hoeing loose soil and irrigation must be timely. Through the comparison of shading and total light, it is proved that the shading seedlings are stretched, large and grow stronger. It grows slowly throughout the summer. In early September, as the sun was weakened, the weather gradually cooled and the shade was removed. At this time, the seedlings are as high as 4 to 5 cm, and 4 to 5 leaves are grown, and the seedlings grow strong. Late October. Seedlings fall, stop growing, prevent cold in winter, stop fertilizing and watering.
