First, select seedlings. The selection of seedlings should meet the following criteria: first, the varieties should be of high quality, the leaves should be light green, contain moisture, and the surface should be intact; Second, the trunk is thicker and more resilient than the root system; Third, the root system is developed, so it is not easy to break when pulling, and the branches can be clearly seen. It is best to choose seedlings around 1 year.
Secondly, make the planting place and method. Platanus acerifolia should be planted in sunny, well-ventilated and well-drained places. The depth of the pit should be moderate, slightly deeper than the root system, and its diameter should be 2-3 times the diameter of the stump. The bottom of the pit should be paved with drainage materials such as bricks and stones. When planting, enough space should be reserved, which requires more than 2~3 meters to facilitate its normal growth and development.
Third, prepare for planting. Dig the pit first, then lay the top of soil or masonry on the bottom, then put the saplings vertically in the center of the pit, and then add fertile soil. In the process of planting, pay attention to avoid bending or twisting the root system.
Finally, cultivate management. Paulownia trees should be watered, pruned and moisturized regularly after planting, especially in dry season, watering times should be increased, and attention should be paid to preventing pests and diseases.
In short, although the growth of paulownia tree is slow, as long as the above aspects are fully considered, certain planting methods and management rules are followed, and persistent efforts are made, it can grow into a beautiful and healthy tree and make certain contributions to the development of urban greening.
