1, transplant technical requirements:
(1) The transplanting season is mainly in spring, supplemented by summer and autumn.
(2) The width of seedbed is 1.2- 1.5m, and the sidewalk is 50cm. The seedbed runs north and south.
(3) The row spacing of transplanted plants is 80×80 cm, and they are planted in two rows in a zigzag arrangement.
2, transplant method requirements:
(1) The whole process of digging, transporting and planting seedlings should be strictly organized to minimize the exposure time of seedling roots.
(2) When transplanting, the seedlings should be graded, and grade A or grade B seedlings should be selected, strictly graded and planted, and mixed planting is not allowed.
(3) Seedlings are required to bring an appropriate amount of original bed soil. Before planting, the main roots should be cut off, the length of the main roots is 15-20cm, and the total lateral roots are 15-20cm.
(4) The leaves on the overground part of transplanted seedlings should be cut off properly, but the terminal buds must be kept.
(5) The planting depth should be slightly deeper than the original seedbed.
(6) Water immediately after planting, and water for two or three times every 3-7 days. The second transplanting is at the stage of DBH 4-5 cm. Although the seedlings have reached the basic requirements of urban greening seedlings, high-quality greening seedlings with certain dry height and crown shape can be obtained through continuous cultivation with sparse planting.

(2) The width of seedbed is 1.2- 1.5m, and the sidewalk is 50cm. The seedbed runs north and south.
(3) The row spacing of transplanted plants is110-120× 80-90 cm, and they are planted in two rows in a zigzag pattern.
2. Requirements for transplanting seedlings:
(1) When digging seedlings, bring soil balls as far as possible, trim the injured roots, and leave 30-40 cm of total lateral roots.
(2) at this time, the broad-leaved tree species are pruned, and the reserved seedling height is 2.8-3.0m ..
(3) Grading the excavated transplanted seedlings, and selecting Grade A seedlings or Grade B seedlings for strict grading transplantation.
3, transplant method requirements:
(1) The transplanting process should be carefully organized and planned, so as to shorten the root exposure time of seedlings and improve the survival rate of transplanting.
(2) The planting depth of seedlings should be 5- 10 cm deeper than the original growing place, and the root disc should not be exposed when planting.
(3) The transplant work shall conform to the requirements of neatness and tidiness. After transplanting, the seedlings should be arranged in rows, neat and orderly, and the edge of Miao Di should be clean and tidy.
(4) Water the root immediately after planting, and then water it two or three times every 3-7 days. Transplanting seedlings of slow-growing trees for the first time. Transplanting for the first time after seedling 1 year.

(3) The row spacing of transplanted plants is 20-40× 30cm.
2. The transplanting method is similar, except that fewer leaves should be cut off properly in the transplanted seedlings to reduce the transpiration intensity. The second and third transplants are basically the same as fast-growing trees.
