Do you have any precautions when transplanting Chinese Sophora japonica? Next, I will give you a brief introduction.
1. Selection of the transplantation time
The best choice for the dormant period of Chinese Sophora japonica is the fall of leaves after autumn and before the new leaves in spring. The best period in North China is late autumn before the soil freezes and early spring after the soil has thawed. South China can choose to transplant during the growing season, preferably during the rainy season or even cloudy days.
2. Selection and breeding of Transplanting Sophora japonica
Transplanting Chinese Sophora japonica should meet the design specifications and quality requirements. The transplanted Sophora japonica should be robust, grow normally, have no serious pests and diseases, and have no serious harm. Lifting machinery and transportation vehicles can reach the transplantation site of Guohuai. Guohuai should be near and not far away. As long as the time is controlled and reasonable and appropriate measures are taken, any tree species can be transplanted.
3. Pre-treatment of Chinese Sophora japonica transplantation
Before transplanting the locust tree, it must be handled well. The crowns of fallen leaves should be pruned before transplantation, bare root transplantation should be pruned again, 1/2-1/3 of all branches and leaves should be pruned, soil ball transplantation should be pruned appropriately, and 1/3 of the branches should be pruned. When pruning, the cut must be flat, the section should be as narrow as possible, the pruned branches should exceed 2 cm, and the cut should be coated with preservative or paraffin wax. There is no need to prune evergreen trees before transplanting. After planting, pruning the broken branches or the branches that are too dense, overlapping, whorled, drooping, slender branches, and pests and diseases that appear during the transplantation process. When pruning evergreen trees, short branches of 1-2 cm should be left, and rooting methods should not be used for pruning. After cutting, apply preservative or wrap the cutting machine. Deciduous trees can leave some branches appropriately. Side branches are easy to germinate.
The trunk is wrapped in sack and straw rope. Generally speaking, evaporation and wear during transplantation can be reduced from rhizomes to branching points.
Four, digging
When digging the ball, make sure that the ball is in good condition, especially in the rainy season. The size of the earth ball is 7-10 times the diameter of the trunk of 1.3 meters, and the height of the earth ball is about 2/3 of the diameter of the earth ball. (The diameter at breast height is 15-30 cm, the diameter of the earth ball is 1 m to 1.2 m, and the thickness is 80-100 cm. The diameter is more than 40 cm, the diameter is about 1.5 m, and the thickness is 1-1.2 m). Pillars must be erected to stabilize the country. Soak the packaging material in water and stand by.
Five, National Sophora japonica transportation
Trucks and cranes should be selected according to the size of the trees. The contact area between the trees and the carriage should be matted to protect the trunk. The earth ball should be moved forward when loading, and the trees should be slightly backward, and corresponding fixing measures should be taken.
Sixth, the planting of acacia
Dig planting holes according to the designed position. The size of the planting hole depends on the root system and the size of the soil ball. The planting holes of bare roots and Chinese acacia are round pits. It should be 60-80 cm larger than the root system or the diameter of the soil ball. 20-30 cm deep. The pit wall should be smooth and vertical. After digging the bottom of the pit, place 20-30 cm of mellow soil. The planting depth should be appropriate, generally flat, with soil traces or slightly above the ground about 5 cm. When planting, choose the main ornamental surface and pay attention to the sunrise surface. Under normal circumstances, tree bends should wind up as much as possible. (Before planting, the diameter at breast height in the sunrise direction must be marked with lead oil.) When planting, plant it upright. The main tip of the crown is on the same vertical line as the root. Keep the tree upright and facing the right direction.
