Liriodendron chinense, also known as Yajiaomu, is a small evergreen tree or shrub. Many branches, dense branches, palmately compound leaves, 5-8 leaflets, dark green and shiny leaves. The plants are plump and beautiful, and have strong adaptability. This is a good potted foliage plant. Suitable for arranging offices, conference rooms, living rooms, balconies with poor light, etc. This is an ideal indoor plant placement. The management technology of its breeding and growing season is introduced as follows. Sow and breed. From late April to early May, pot planting was carried out with humus soil or sandy soil. First, mix 2 parts of rotten leaves 1 part of soil, put them in a basin, and flatten 2/3. Sow the seeds evenly in the flowerpot and cover them with fine soil to avoid seeing the seeds. Then put the sowing basin into a container filled with water, let the water slowly penetrate into the basin from the hole at the bottom of the basin until the soil on it is wet (water cannot flow into the basin from the mouth of the basin), and then keep the soil wet. Under the condition of 20-25℃, the seedlings gradually emerge after 15 days. Transplant when the seedling height is 5- 10 cm.

Cutting propagation. Before the new shoots grow in spring, cut 1 annual branches as cuttings, and the ear length is 8- 10 cm. Remove the lower leaves, keep the upper 1-2 leaves, and cut the lower end of the cuttings into horseshoes. The seedbed is made of river sand or vermiculite, the cuttings are inserted by 2/3, the height of the arch shed is 10- 15 cm, and it is covered with plastic film to keep enough moisture. When the bottom temperature is 25℃, it can take root and be planted in a pot for 4-6 weeks.

All-light fog propagation. Using the growing season of plants, artificially create a high-humidity microenvironment, so that plants can reproduce asexually under high temperature and high humidity. First, lay bricks on the bottom of the cutting pool, and lay 30 cm thick sterilized river sand on it. Secondly, select cuttings with a length of 8 cm, remove the lower leaves, dip the roots with abt rooting powder 1000 mg/kg for 20 minutes, and insert the cuttings into the pool sand 1/2. It is best to insert in the afternoon, spray at 8- 17 two weeks before insertion, with an interval of 3 minutes, and stop spraying at night; Third, the interval between left and right is 7-8 minutes; After the fifth week, the interval will remain at 10 minute, when the roots have taken root (in case of low temperature or rainy weather, the rooting time may be relatively late). When the seedlings grow strong, they can be planted separately.

Propagation by layering with high branches. It can be carried out from late April to mid-June. Select 2-year-old branches and peel them annularly, with the width of 1- 1.5 cm, so as to see that the green cambium is deeper. Wrap wet moss or decomposed cow dung and pastoral soil (1∶ 1) or humus around the wound, and finally wrap it tightly with plastic film, and tie the upper and lower ends tightly. It takes about 40 days to take root, which is labor-consuming and time-consuming, but the root system is good and the survival rate is high, which is helpful for plant shaping and pruning.

Liriodendron likes semi-shady environment and can grow well in a bright shed with sunshine for 3-4 hours. It can also be directly placed outdoors, shaded by 75% shading net, often sprinkled with water on the leaves, and applied with decomposed cake fertilizer or farmyard manure every 10 day, and the basin soil is kept dry. Pay attention to the pest control, pruning, tying and pulling of Liriodendron chinense in Gao Qian. It is important to note that asexual seedlings should be completely shaded within 7 days after transplanting in high temperature season; Sunny day 8- 15 days 9- 14: 30, all exposed at night; /kloc-within 0/6-20 days, it will be shaded by 20% during the day and fully exposed at night, and then it will enter the normal management stage.
