The demand for soil is not high, like the slightly acidic soil with high dryness and rich humus, especially the sandy soil with deep, fertile and moist soil and good drainage. Do not tolerate drought and barren soil, avoid saline-alkali soil and waterlogged land, planted in poorly drained wetlands, will cause poor growth, root rot, leaf shedding, and eventually lead to the death of the whole plant.

Propagation technique of Cinnamomum chinense

1. Twig cuttings: select excellent mother plants with good varieties, exuberant growth and no diseases and insect pests. When cutting cuttings, cut them into 2cm, keep 1cm leaves at the top, cut the top into a flat mouth, cut the base into a bevel, and the slope should be smooth to facilitate cutting and rooting. After disinfection, the cuttings were soaked in rooting powder for 10 minutes and then cut. After the cuttings were finished, the cuttings were immediately watered to cover the film and sunscreen or grass curtain. 2000 times carbendazim solution was sprayed once every 7 days, and 0.2% urea or potassium dihydrogen phosphate solution was sprayed every 10 days.

2. High-altitude striping: the high-altitude crimping method is mostly carried out before sprouting in spring, can also be carried out during the summer growth period, and has a good effect in the plum rain season. Cut or ring peel the branches born in 2012, fill them with rice bran ash, moss, culture soil, perlite and other substances to cover the wound, often keep moist, but the moisture is not easy to be too much, after rooting can be cut off from the mother plant.

3. Rootstock grafting: the rootstocks used for grafting Siji cinnamon mainly include privet, white wax, clove, tassel and so on. The disadvantage of privet as rootstock is that the root system is too developed, it is not suitable for pot planting, and it blossoms late. The disadvantage of white wax as rootstock is that it has a short life span, and it is easy to shed leaves and blossom less in winter. When cloves are used as rootstocks, the trunk is thick and thin, and the tree is top-heavy. Tassel rootstock has good affinity, drought and cold resistance, strong adaptability, long life, and the age of the tree can be more than a hundred years. Therefore, the most suitable rootstock for grafting propagation of potted sweet-scented osmanthus is tassel.
