Big tree transplantation refers to transplanting deciduous trees with diameters above 20 cm and evergreen trees with diameters above 15 cm. As the saying goes, “people move and trees die.†Due to poor conditions for transplanting large trees, the excavated root system is generally too small. If the management is not strengthened, it is difficult to survive. Therefore, in order to increase the survival rate of large trees, the following needs to be mastered: skill:
Before digging, determine the diameter of the earth ball. For large trees that have not been treated with root cuttings, the diameter of the soil ball is 7 to 10 times the DBH. In the case of a large tree that has been shrunk and cut off, the soil ball should be loosened by 10 to 20 centimeters outward on the basis of the root cut. Then dig a groove of 60-80 cm deep at the outer edge of the circle of demarcated earthballs, which is also the thickness of the soil ball. Usually 50 to 80 cm, and then tied with straw, pouches, sacks and other soft materials.
The above-ground shoots are protected by branch cuts, and the trunk is tied with straw ropes to reduce the evaporation of water.
In summer, the temperature is high and the water evaporates quickly. In order to reduce the amount of evaporation, shelters should be built to prevent sun exposure. However, the shading during transport in hot weather should not be too strict, and it must not be sealed, nor can it touch one side of the tree.
After the transplanting, support was taken to prevent lodging. Avoid continuous watering to prevent rot caused by poor ventilation. If you need watering, you must use "GGR series rooting powder" to promote the initiation of new roots.
Immediately after autumn, remove the rotted grass ropes that are tied up on the trunk, and then immediately apply a white coating agent such as lime sulfur. In winter frost, the trunk and main branch can be wrapped with antifreeze mats (non-woven linen, plastic, film, straw ropes) to reduce the influence of frost on the big trees and prevent the freezing of the trees. When the temperature rises steadily above 5°C Remove the wrapper.
Within two years after the transplant, full-time technicians should be equipped to perform a series of maintenance and management tasks such as pruning, stripping, spraying, fertilizing, watering, preventing cold, and preventing pests and diseases.
