[0002] Arbors are tall trees with independent trunks growing from the roots, and the trunk and crown are clearly distinguished. Arbors are the backbone tree species in gardens. They are not only an important part of garden greening, but also a key factor in improving the quality of garden landscapes and ecological benefits. Arbors add rich visual effects to garden landscapes with their tall crowns and lush branches and leaves, which can significantly improve the beauty of gardens; they can improve the microclimate through the distribution of their branches and leaves, reduce the impact of extreme climate on people; absorb pollutants in the air and improve environmental quality; provide growth conditions for shade-tolerant plants, epiphytes, etc., and improve the biodiversity of gardens.

[0003] In the process of garden tree transplantation, in order to ensure the greening effect after tree transplantation, tree branches and leaves are usually not trimmed significantly. However, due to the tall tree body and the crown size of 2 to 3 times the diameter of the transplanting soil ball, water metabolism is unbalanced during transplantation, evaporation is large, and the tree body is short of water. At the same time, due to the problem that the root system is easily damaged during transplantation and the root system recovers slowly after damage, the mortality rate of the tree after transplantation is high, which seriously affects the aesthetics of the garden. Therefore, it is necessary to provide a garden tree transplantation method to improve the survival rate of the tree after transplantation and shorten the recovery period of the tree after transplantation. Summary of the invention

[0030] In the present invention, the basal fertilizer in step (2) is a potassium sulfate type compound fertilizer; 1-2 kg of basal fertilizer is applied to each tree, preferably 1.2-1.8 kg, more preferably 1.4-1.6 kg, and more preferably 1.5 kg; the water retaining agent is composed of chitosan and polyacrylamide in a weight ratio of 2-3:0.8-1.2, preferably in a weight ratio of 2.2-2.8:0.9-1.1, and more preferably in a weight ratio of 2.5:1; 30-70 g of water retaining agent is applied to each tree, preferably 40-60 g, more preferably 45-55 g, and more preferably 50 g.

[0031] In the present invention, chitosan and polyacrylamide cooperate with each other to significantly improve the water retention effect, which is beneficial to the absorption and utilization of water in the soil by the tree roots.

[0032] In the present invention, the wrapping in step (3) is performed using PLA non-woven fabric or garbage fabric, preferably PLA non-woven fabric.

[0033] In the present invention, the root protection composition in step (3) is prepared from the following components in parts by weight: 400-600 parts of humic acid, 80-120 parts of ABT rooting powder and 8-12 parts of sodium nitrate; preferably, it is prepared from the following components in parts by weight: 450-550 parts of humic acid, 90-110 parts of ABT rooting powder and 9-11 parts of sodium nitrate, and further preferably, it is prepared from the following components in parts by weight: 500 parts of humic acid, 100 parts of ABT rooting powder and 10 parts of sodium nitrate.

[0035] In the present invention, in step (4), the tree is pruned before being transplanted into the planting hole or planting groove.

[0036] In the present invention, during the pruning, the evergreen coniferous trees are not pruned too much, only the dead and diseased trees and injured branches are pruned; for the deciduous trees with large growth potential, especially the trees with strong growth potential and easy to extract new branches, strong pruning can be carried out, and more than 1 / 2 of the crown can be pruned, so as to reduce the burden of the water system, maintain the water balance in the tree body, and make the tree stable after planting and not sway in the wind; for the trees with slow growth effect, thinning can be carried out, all or part of the leaves can be cut short, dead and diseased branches and overcrowded branches can be removed, and 1 / 3 to 1 / 2 of the overlong branches can be pruned. When pruning, the outside should be kept low and the inside high; at the same time, the root system should also be properly pruned, mainly to cut off the broken roots, split roots, diseased and insect roots and overlong roots. The pruning mouth should be flat and smooth, and the preservative should be applied in time to prevent excessive evaporation, drought and damage by diseases and insects.

[0037] In the present invention, the preparation method of the improved soil in step (4) is: the deep soil obtained in step (1) is mixed with coarse sand, rice husk, organic fertilizer, peat soil, and ferrous sulfate in a weight ratio of 40-60:8-12:8-12:6-10:6-10:0.04-0.06 to obtain improved soil; preferably, the deep soil obtained in step (1) is mixed with coarse sand, rice husk, organic fertilizer, peat soil, and ferrous sulfate in a weight ratio of 45-55:9-11:9-11:7-9:7-9:0.04-0.06; more preferably, the deep soil obtained in step (1) is mixed with coarse sand, rice husk, organic fertilizer, peat soil, and ferrous sulfate in a weight ratio of 50:10:10:8:8:0.05.

[0038] The invention adds coarse sand and rice husk into the deep soil, which is beneficial to improving the air permeability of the soil and preventing the roots of the transplanted trees from rotting, thereby significantly improving the survival rate of the transplanted trees.

[0039] In the present invention, the specific maintenance method of step (5) includes: building triangular piles or straight piles for protection after the trees are transplanted; wrapping straw ropes around the trunks of the trees and above the ground, and covering them with plastic sheets for heat preservation and moisture retention; controlling diseases and pests of the trees and regularly fertilizing the leaves of the trees.

[0040] When building triangular piles in the present invention, a triangular steel wire rope (with adjusting bolts-basket screws) is tied at 1 / 3 to 1 / 2 of the height of the tree trunk, and the tree crown is pulled obliquely in three directions to tighten it. The triangular rope must be in the windy direction, and the other two are evenly distributed to prevent it from falling down.
