Chinese name of Araliaceae
Chinese name: Liriodendron chinense.
Leaves with 6- 10 lobules, petiole cylindrical, 9- 19 cm long, nearly hairless, lobular leathery, with different sizes, linear and rectangular, 3-1/cm long, 0-3.5 cm wide, and apex. Petiole 0.5-4 cm long, almost glabrous.
Liriodendron likes warm, humid and semi-cloudy environment.
The optimum growth temperature of Liriodendron chinense is 27℃. September is 27℃, and September to March is 2 1℃. It can still grow normally at a high temperature above 30℃. The temperature in winter is not lower than 5℃. If the temperature is lower than 0℃, plants will be frozen and defoliated, but if the stems are intact, new leaves will grow in the next spring.
Liriodendron prefers wet to dry. When the air humidity is high and the soil moisture is sufficient, the stems and leaves grow luxuriantly. But too much water will cause waterlogging and root rot. If the basin soil is short of water or dry and wet for a long time, defoliation will occur. Liriodendron chinense has certain adaptability to temporary drought and air drying.
Liriodendron has a wide range of adaptability to light, and can grow in full sunshine, half sunshine or half shade. However, the intensity of light has a certain relationship with the color of leaves. When the light intensity is high, the color of leaves turns pale, and when it is half cloudy, the color of leaves turns dark green. In bright light, the color of spotted leaf species is more vivid. If you have about 4 hours of direct light indoors every day, you can grow well. Varieties with yellow and white stripes, such as weak light or biased application of nitrogen fertilizer, will blur their stripes and lose their original characteristics.
The soil should be fertile, loose and well drained. Pot soil is a mixture of peat soil and humus soil, and the annual branches of 6-8 cm are cut from the mother plants that have grown for several years, or the cut branches are changed to pots and cut again in spring as materials. Remove the inserted leaves and use the pre-soaked leaves as the cutting substrate.
If there is any stain, insert the cuttings 3 into the sand or perlite, and the water level in the container should always be higher than the cuttings basin 2. Then in the bright place of scattered light, cover the cuttings basin with a transparent plastic cover, and keep the temperature at 25℃. After 40 days, the root system of cuttings will be generated. At this time, Liriodendron seedlings can be transplanted into 6-8 inch pots, and the pot soil should be filled with fine and fully mixed fertile nutrient soil, and then watered after planting.
