Methods for Raising Fraxinus chinensis
As an excellent garden tree species, Fraxinus chinensis is highly favored for its strong adaptability to the environment and unique economic value. This article systematically analyzes the key points of the full cycle of care for Fraxinus chinensis from seedling cultivation to adult tree management, helping growers master scientific maintenance methods to achieve efficient cultivation.
Key Points for Environmental Control of Fraxinus chinensis
Temperature and Light Management
Fraxinus chinensis has a wide temperature tolerance range from -20°C to 40°C, but seedlings should be protected from direct sunlight. It is recommended to use 50% shade net protection from 10:00 to 15:00 in summer, and to ensure at least 4 hours of direct sunlight every day in winter. In spring and autumn, it can be exposed to natural light throughout the day.
Water Supply Strategies
In the growing period, soil moisture should be maintained at 60%-70%, and a single watering volume for adult trees should reach 30-50 liters. The circular trench irrigation method can improve water utilization efficiency, and drainage ditches should be dug during the rainy season to prevent waterlogging. Only one补水 is needed per month during the winter dormancy period.
Propagation and Shaping Techniques for Fraxinus chinensis
Efficient Cutting Propagation Method
Methods for Raising Fraxinus chinensis
Select 1-year-old semi-lignified branches, retain 3-4 buds, and after treating with ABT rooting powder, plant them. The matrix should be prepared with a peat:perlite ratio of 3:1, maintaining an environmental humidity of 80% at 25°C, and roots will form in about 20 days.
Pruning Essentials for Shaping
The recommended height for the trunk is 1.8-2.2 meters, with 3-5 robust lateral branches at a 45° opening angle. Thinning should be carried out every March, removing crossing branches and diseased branches to maintain a canopy light transmission rate of over 30%.
Disease and Pest Control System for Fraxinus chinensis
Solutions for Diseases
Before the peak period of brown spot disease, spray 75% carbendazim 600 times liquid, and combine with the removal of diseased leaves. For sooty mold disease, use 10% benz醚甲环唑 2000 times liquid, spraying once every 15 days.
