Liriodendron Chinense Native Habits
Liriodendron chinense (Chinese tulip tree) is fond of light, mild and humid climates, and has a certain cold tolerance. It likes deep, fertile, wet and well-drained acid or slightly acid soil (pH4.5-6.5). liriodendron chinense cannot grow well in arid land, and it also avoids low humidity and waterlogging.
Liriodendron chinense is usually born in mountain forests or forest margins at an altitude of 900-1 000 meters, with scattered distribution and small pure forests.
Liriodendron Chinense Propagation
Liriodendron Chinense Seed Propagation
Liriodendron chinense propagates from seeds and must be artificially pollinated. After selecting seeds in autumn, they accumulate in the middle layer of wet sand for winter, and sow and raise seedlings in the next spring. The third year seedling height of 1 meters or more time can be out of the nursery planting. The root should be protected when grafting. Cultivated soil with a deep, fertile, well drained acid and slightly acid soil.
Liriodendron Chinense Cutting propagation
In addition to sowing seedlings, Liriodendron chinense (Chinese tulip tree) can also be used to raise seedlings by cutting. In the southern area of Henan Province, a hard cutting method is used, and its seedling raising method is simple and easy to learn. In the second half of February after deciduous, the choice of robust mother tree, cut annual 5 mm above thick branches as cuttings, ear length about 15 centimeters, each ear should have 2 to 3 full buds, the lower cut flat cut, according to the plant row distance 20 centimeters ×30 centimeters inserted into the soil 3/4, cutting before the use of root powder soaked for about 30 minutes. Cuttings should be inserted along with the mining, after inserted to have shading facilities, frequently spray water.This method becomes seedling rate can amount to 80%, annual seedling grows to 80 cm above, can give nursery afforestation likewise.
Liriodendron Chinense Disease Control
Many diseases and insect pests of Liriodendron chinense, the main diseases and insects of Liriodendron Chinense are anthrax, white silk disease.
Anthrax damage Liriodendron chinense mainly occurs on the leaves, the disease spots are mostly on both sides of the main side of the veins, the initial brown small spots, round or irregular shape, the central dark brown and its outer color is lighter, the edge is dark brown, the disease spots often around the brown green halo, the late disease spots appear black small dots. The pathogen was Gloeosporiumsp, belonging to the genus Discospora of the order Discospora of the family Discospora of the order Discospora. The conidia have no setae. The conidia are oblong, colorless, unicellular and contain 1 to 2 oil globules. The pathogen overwintered in mycelia and conidia on the residual plants and fallen leaves. Conidia spread with wind and rain, air flow, from the host wounds or stomata invasion, in the humid climate conditions of Meiyu serious disease.
During the onset period, 50% Anthrax Fomex WP was sprayed with 1000-1500 times solution, once every 10-18 days, for 2-3 consecutive times. The symptoms of white silk disease are: first the root layer of the affected seedlings rots, and then the aboveground parts wilts and dies. Prevention and control measures: seedlings sick with prevention, drugs can only play a controlling role.
1. In the onset period, with 5% lime water or 1% copper sulfate pouring seedling roots, can also be used per mu of 100 pounds of lime scattered on the ground.
2. Increase the application of organic fertilizer: improve the growth of seedlings, enhance resistance, increase microorganisms.
3. Crop rotation: If possible, crop rotation of seedlings and grasses should take place over a period of 4-5 years.
Liriodendron Chinense Species Classification
Because of its unique leaf shape, golden autumn leaves, straight trunk end, beautiful tree shape, deeply loved by people, Liriodendron Chinense is widely used in gardens. However, people often cannot distinguish Chinese tulip tree, North American chinese tulip tree and hybrid Chinese tulip tree when buying seedlings, and some people even mix the three together, collectively referred to as "Chinese tulip tree". This is very wrong.
Liriodendron chinense (Chinese tulip tree) is a large deciduous tree in the magnolia family. After the Quaternary glacial climate, there are only two species of this genus: Chinese tulip tree and North American Chinese tulip tree. They are called living fossil plants and are among the most precious tree species in the world.At present, Chinese tulip tree is only found in China in the wild, and is endemic to China. North American Chinese tulip tree is produced in the southeastern part of the United States. It is not only very similar to Chinese tulip tree in morphology, but also presents an intercontinental discontinuous distribution pattern from East Asia to the eastern part of North America in geography, which is of great scientific significance.
Liriodendron Chinense Distribution
Liriodendron chinense distributes from the south of the Qinling Mountains to the north of Vietnam, from Zhejiang Province in the east to Yunnan Province in the west.
