How many days does it take for the camphor tree transplanted in spring to germinate
As a main species for urban greening, the germination of camphor trees after spring transplantation is of great concern. Factors such as root damage and environmental changes during the transplantation process can affect their recovery speed. Mastering scientific management methods can help this greenery recover more quickly.
Key factors affecting the germination period
Level of root protection
Plants transplanted with soil balls generally germinate 10-15 days earlier than bare-root transplants. A complete soil ball can retain more than 70% of the fine roots, maintaining water absorption capacity. It is recommended that the diameter of the soil ball be 6-8 times the diameter of the trunk, and secured with straw rope.
Environmental adaptability
The first 20 days after transplantation are the key period for seedling establishment, maintaining soil moisture at around 60%, and avoiding waterlogging and root rot. Use shade nets to control light intensity, gradually transitioning to full sunlight.
The four-step method of scientific transplantation
Choosing the best timing
In the Yangtze River Valley, it is recommended to transplant from late March to early April, when the ground temperature rises to 12℃ or higher, and the sap starts to flow but has not fully germinated. Avoid cold spring weather and choose consecutive sunny periods for operation.
Technique for truncating the trunk
Retain a height of 2.5-3 meters of the main trunk and apply wound healing ointment to the cut. Remove 80% of the lateral branches, leaving 3-5 main branches to form a framework. This can reduce the transpiration area by up to 60%, improving survival rates.
Using root-promoting agents
Immediately spray a 200ppm naphthalene acetic acid solution after pruning the roots to stimulate the formation of callus tissue. At planting, add a mixture of 5kg of decomposed organic fertilizer and root-promoting powder to each hole to promote the development of new roots.
Controlling planting depth
Keep the original soil mark 3-5cm higher than the ground surface, backfill the soil in layers, and compact it. Set a tree disk with a diameter of 1.2 meters and build a 10cm high embankment around the edge for convenient watering.
Key points for post-transplant care
Apply a compound fertilizer (15-15-15) of 200g/plant every month after new buds have sprouted. Pay attention to the prevention and control of the camphor nest moth, and promptly cut off any infested areas. With three years of careful management, the tree can fully recover its canopy shape.
