Morphological characteristics:
It is an evergreen high shrub to small tree, and the model specimen mother tree is now preserved in Dongxi Township, Cangxi County.
The tree is about 100 years old, with a height of 6 meters, a diameter of 22 centimeters in diameter, and a crown of 5.8 meters. At present, it is growing moderately.
Cixiang laurel is spherical to ellipsoidal with tightly branched branches. The bark is light grey, with small lenticels, round or elliptical, and sparsely distributed. The average branching force of standard plants was 2.6, and the average length of spring shoots was 16.3 cm. Leaves green to dark green, hard leathery, slightly lustrous; broad leaves in early spring, obovate or oblanceolate, entire margins; late spring shoots and summer and autumn fall leaves long, oblong, with sparse serrations in the middle and upper leaves; The surface is flat, with an average leaf length of 9.9 cm, an average leaf width of 3.5 cm, and leaf margins in the form of microwaves, which are counter-rolled. Lateral veins 10 to 12 pairs, relatively neat; tip short to obtuse; leaf base cuneate to broadly cuneate. The first and the last stage of flowering are cymes; in the central period, the panicles are inflorescences, with obvious peduncles, and the corolla is light yellow to lemon yellow. Corolla flat, slightly buckled; corolla lobes elliptic, deeply lobed; floral denser.
Ecological habits:
Cixiangui has wide adaptability and strong resistance to stress. It prefers neutral, acid-rich, organic-rich soils that require a cool, moist microclimate and a certain degree of cold resistance. Germination period is earlier each year. In the northeast and north parts of China, the potted plants can normally bloom; in the Qinling Mountains and the areas south of the Huaihe River, the open land can safely overwinter; in places with higher temperatures throughout the year, such as Fujian, Guangdong, Guangxi, and Hainan, they can adapt to the annual blooming.
According to statistics, each new shoot of Japanese Xianggui has three to four pairs of leaves, and each leaf has two to three pairs of stacked axillary buds in the leaves. The other fresh shoots generally have only two to three shoots per new shoot. For leaves, there are only 1 to 2 pairs of solitary or stacked axillary buds in each leaf blade. This resulted in an objective material basis for the greater flowering and flowering potential of N. sinensis. The total flowering period can reach more than 200 days, and the variety is also named as Xiangxiang Guiri Xianggui Shrub Ball; the diameter of the ground is 5 cm, and the height is 50 to 100 cm. .
Use value:
It is a high-grade green tree species with its high ornamental value, greening, aroma, and colorization. It can be cultivated into a globular arbor with graceful posture. It can also be cultivated into thick spherical shrubs with branches and leaves. It can also be potted, or branches and leaves can be used for flower arrangement to add greenery to the living room. The simultaneous development of the ornamental value and use value of the Japanese Xianggui can make its comprehensive economic value more than double that of other sweet-scented osmanthus products.
In addition to the value of the seedlings themselves, the Japanese osmanthus planted with 1 mu can also produce 300 kilograms of flowers annually, worth 3,000 yuan. If it is made of essential oils, the added value is even higher. The extraction rate of Rixiangui oil is more than 1 times that of other sweet-scented osmanthus flowers. The extraction volume of 1 mu is 0.5 kg and worth 10,000 yuan. Taken together, the direct economic value of planting 1 mu of Xianggui can reach more than 20,000 yuan. In addition, a piece of Japanese fragrant Guilin, in addition to the ornamental and practical value, there is a very high value of tourism, the comprehensive benefits brought about by this aspect are also considerable.
The planting and utilization of Japanese osmanthus 'has a well-developed root system, a fast growth rate, and a green leaf color throughout the year for good ornamental effect. In addition, the variety has a long flowering period and beautiful appearance. In the Mid-Autumn Festival, National Day, New Year's Day and the Spring Festival, China's four major festivals can continue flowering, aroma hit people, indicating that it is a rare evergreen flower tree species.
Rixianggui's breakthrough in the general awareness of the "fragrant osmanthus is not diligent, open ground osmanthus and not fragrant," has become a famous osmanthus species in China. This may be the main reason why the Xiangxiong series seedlings have always been sold well and sold well over the years.
Sweet osmanthus seedlings can be potted or planted. However, large-scale planting is generally based on planting. Sun Xiang Gui Xi sunshine, bogey dark, hi moist, cold and heat-resistant, so you can choose to light more sufficient land for planting.
