Preparation before transplanting Transplanting time The best conditions for transplanting trees in the Fairy Pine tree before the budding in spring (early April) are best. Therefore, when the ground temperature gradually rises, the damaged root system can be restored in a relatively short period of time and new roots can be produced.
The tree pits of the newly planted land shall be dug one week before transplanting the tree pit. The diameter of the pre-excavated tree pit shall be 40 to 50 cm larger than the diameter of the transplanted tree soil ball, and the height shall be approximately 15 cm higher than the height of the soil ball. The excavated earth should be separated from the topsoil and the bottom soil (if the soil can be spread out for drying), the bricks, tiles, and other impurities in the soil should be cleaned.
The pruning and transplanting of transplanted trees will damage the root system and weaken the ability to absorb water. Therefore, reducing the water transpiration of the tree is one of the keys to improving the survival rate of transplanting Fatong trees. Because the Fatong sprouts are strong and resistant to pruning, the trees that are to be transplanted should be severely cut. First, the short branches should be cut short and the remaining branches of the short cut tree should be thinned. After pruning, large branches and cuts are processed in time, and the methods often used are white paint, paraffin or tying with plastic cloth.
The irrigation and irrigation of the trees to be transplanted should be carried out 3 to 4 days before transplanting. In accordance with the principle of pouring feet, the root system should absorb enough water. After the water is poured, the excavation is easy to be a ball, and it will not spread out because the soil is too dry.
Digging, lifting and planting Earthballs Earthballs are typically 6 to 8 times the diameter of the trunk and 65% to 80% of the diameter. It is better to dig bigger if possible. When excavating, first remove the top soil from the base of the trunk and excavate at a defined diameter. The earth ball should be dug into an inverted conical shape (ie, it should be large and small). After the initial shaping, it should be rounded off to make the surface as smooth as possible to facilitate dressing. The big roots that need to be cut off must be sawed off with a saw, but not with an axe. The root section was treated with sulphur powder and ABT rooting agent in a paste ratio of 2:1 for wound treatment.
After dressing the earth ball, we must promptly pack it. During the dressing, the bottom of the soaked sacks was applied to the back and then wrapped in straw ropes. The bandaged grass rope must be tight and the joints should be minimized. Finally, the rope head should be tightly tied to the root of the tree. After the soil ball is wrapped, the trunk is also tangled with a soaked straw rope, and it must be wrapped around the branching point.
When lifting and lifting, special attention should be paid to not damaging the bark. The author puts rubber sheets (car tires) and used quilts under the steel wire ropes, and achieves good results. The trunk is not damaged. In addition, when lifting, be careful not to crush the soil ball. Pay attention to the fixed transport, to prevent rolling, so as not to damage or hurt.
Before the planting, the pre-duged tree pits shall be sprayed and disinfected. After thoroughly decomposing and fermenting the circle fertilizers, the soil and the fertilizer shall be fully mixed in a ratio of 6:1 and then backfilled to the bottom of the pits to a thickness of 15 cm. about. When using a crane to lift a tree, sprayers are used to sterilize the ball in all directions. After disinfection, slowly put it down, place the tree in the direction of the original growth place (ie, Nanji Branch), add solid soil after standing, and coffer, and then water it.
Post-transplantation management Watering After planting water, generally two to three days, two waters, and three to three to three days. Later, depending on soil moisture, each watering should be thoroughly emptied, and the topsoil should be cultivated in time. In addition to normal watering, the straw ropes that are wrapped around the tree should often be sprayed in the hot summer season to keep it moist.
In addition to the application of basal fertilizers, fertilization of large trees should be carried out after fertilization. The use of N, P and K fertilizers is the best. Fertilization can be conducted once every 20 days, and fertilization stopped at the beginning of September. Fertilization should be based on the principles of weak trees and multiple facilities and strong trees. For particularly poorly growing trees, infusion can also be used to restore tree vigor.
The prevention and control of pests and diseases in summer is the season in which pests and diseases of Fatong occur frequently. Prevention and treatment should be based on the principle of “prevention first, prevention and control combinedâ€. For some of the more stubborn diseases (such as Tianniu), we must adopt a multi-pronged approach to control.
Fatong Big Tree Transplanting Technology
Transplanting large trees generally requires cutting roots around the roots 1 to 2 years in advance to promote fine roots to facilitate their survival. However, some projects require the big trees to be transplanted in one place because of time constraints or other reasons. The author's unit once transplanted 25 to 40 centimeters thick Fatong trees once. They have all achieved success. The survival rate of the transplanted trees is high and the growth is good. Now the technical points summarized by the author are introduced as follows: ,for reference only.
