Cultivation methods and matters needing attention for double-tree
As a high-quality tree species with both ornamental value and ecological benefits, Chongyang is favored for its unique umbrella-shaped crown and anti-pollution characteristics. However, in order for this common southern tree to grow healthily in a home environment, scientific management methods are needed. This article will systematically sort out the key points of maintenance from environmental regulation to pest and disease control. Environmental conditions regulate the balance between temperature and light. Doughnut is most suitable for growing in the range of 20-30℃. Although it can withstand low temperatures of-5 ℃, continuous frost will cause the branches to dry out. It is recommended that the northern region adopt cover film for root protection in winter, and use it with sunshade nets when it exceeds 35℃ in summer. Direct light should be guaranteed for more than 5 hours a day, and a south-facing balcony or courtyard open space is an ideal cultivation location. The key points of water management follow the principle of "seeing dry, seeing wet". Maintain soil water content at 60%-70% in spring and summer, and gradually reduce it to 40% in autumn. Using the dipping basin method to supply water can avoid hardening of topsoil. In the rainy season, attention should be paid to the setting of drainage ditches to prevent root rot caused by accumulated water.

3-10 Nitrogen, phosphorus and potassium compound fertilizers (20-20-20) are applied every month during the monthly growth season, and bone meal is added in late autumn to enhance cold resistance. It is recommended to use slow-release fertilizer granules for potted plants and spray ferrous sulfate solution every season to keep the leaves green. It is recommended to keep the height of the stem at 1.5-2 meters, and the bifurcation angle of the main branch is controlled at 45-60 degrees. Cutting is carried out in early spring every year to remove crossing branches, pest and insect branches, and retain the "three-pronged and nine-topped" skeleton structure. Bonsai shapes can be treated with aluminum wire coil binding and core picking. Analysis of propagation technology: Soak seeds in warm water at 45℃ for 12 hours before sowing, and after 20 days of germination, the emergence rate can reach 85%. Semi-lignified branches are selected for cuttage, soaked in indole butyric acid solution, and inserted into vermiculite matrix, maintaining 80% humidity for about 40 years.
