Family: Duyingke Duying Latin name:
Elaeocarpus sylvestris Aliases:
Sandu Ying, Sheep urine tree, Gall tree Morphological characteristics:
Evergreen tree, 10-20 meters high, oval crown. The bark is dark brown and smooth. Branchlets reddish brown, young branches sparsely pubescent, glabrous later. The leaves are leathery, obovate to obovate-lanceolate, 4-12 cm long, 1.5-4.5 cm wide, apex obtuse, base wedge-shaped, and obscure serrations above the middle of the leaf margin. Flowering from June to July, racemes axillary. October fruit ripe, stone fruit, oval. Distribution and habits:
It is produced in southern China, and distributed in Zhejiang, Jiangxi, Fujian, Taiwan, Hunan, Guangdong, Guangxi and southern Guizhou. It is mostly born in the mountain woods below 1000m.
Like warm and humid environment, cold resistance is slightly worse. Slightly shade-resistant, well-developed root system, strong budding ability, and pruning resistance. Likes good drainage, moist, fertile acid soil. It is suitable for growing in acidic yellow soil and red-yellow soil. If it is planted in the plain, it must be well drained and the growth rate is moderately fast. Strong resistance to sulfur dioxide. Reproduction and cultivation:
Sowing or cutting propagation. Autumn fruits are harvested when they are ripe, piled up until the flesh is softened, rubbed and washed to clean the seeds, removed after being dried, and then planted, or the wet sand is layered until the next spring sowing. The seeding space is about 20cm, the soil is about 2cm thick, and then the grass is covered with moisture. In that year, the height of the seedlings can reach more than 50cm. In Hangzhou and other places, it is necessary to shed or cover the grass to prevent cold. It was planted once in the spring of the next year to expand the row spacing of the plants. The transplanting time should be carried out in the early autumn or late spring. The small seedlings should have the soil, and the large seedlings should have the soil ball. After transplanting, some branches and leaves should be properly removed in combination with shaping. application:
Du Ying has four seasons with lush green foliage, a rounded crown and a round crown. After the frost, some of the leaves turn red and red and green. Background trees, or rows of green walls, are used for concealment and sound insulation. Due to its strong resistance to sulfur dioxide, it can be selected as a tree species for greening and shelterbelts in industrial and mining areas.
