The Hengshui Garden Bureau of Hebei Province received a notice this winter and transplanted 10 giant hedgehogs on Injin Street with a DBH of about 20 cm. Because Injun Street is a small commodity wholesale market, with frequent staff movements and many vehicles, it is necessary to make adequate preparations before construction to achieve a quick fix. It can ensure the survival rate of trees and not affect people's activities in the streets.
Prepare for transplantation
Cranes, transport vehicles, professionals (high-saw operators, skillful planers, skilled workers for clearing branches), digging tree holes for planting, preparing pine poles for scaffolds, and wire and other tools.
prune
Use a high-branched saw to cut off the main branches at the branch points of the locust tree by 1 meter. The main branches of each tree should not be trimmed together. It is best to make a high-low drop, with a difference of 3 cm to 5 cm. The main branch leaves some twigs. According to many years of transplant experience, leaving some branchlets easy to sprout. During operation, saw 2 cm to 4 cm on the back of the main branch, and then saw the underside of the back saw and saw the branches.
Excavate
Dig out at a radius of 60 cm around the root of the hedgehog, planing a ditch 40 cm to 50 cm wide and 60 cm to 70 cm deep. Use a saw to break the roots. After reaching the depth, use shovels to dig diagonally. The width of the shovel is about 50 centimeters. Finally, the soil ball is trimmed into an orange shape with a diameter of about 120 centimeters and a height of about 60 centimeters.
Hanging trees and loading vehicles
Lift the tree up by grabbing the upper part of the trunk with a crane-wide strap. If it doesn't move, pull the tree trunk to the side to reveal the long roots of the tree. Slowly put the tree down on the ground. Use scissors and a saw to repair the root of the earth ball. The principle of rooting is the bottom of the tree. The root is level with the bottom of the earth ball. Move the crane-specific wideband to the lower half of the tree trunk. The crane lifts the tree. A worker holds the tree head and uses the principle of leverage to keep the tree level. Put the earth ball on the root first and then put the trunk on the car. For help, put a mat on the trunk of the trunk.
Planting
In the nursery, dig a planting hole, 2 meters in diameter and 1 meter in depth. The bottom of the tree hole is about 30 centimeters thick, making the outer ring high and the middle lower. The locusts were slowly lifted by cranes. The workers supported the tree trunks, placed the soil balls in the tree cavities, kept the trunks downright, and filled the soil balls. Fill in 30 cm after the artificial step, do not step on the soil ball, and then continue to fill the soil after 20 cm. Finally fill the earth ball about 10 centimeters or more, and step on the real earth ball outer ring. The soil above the earth ball is patted with iron shovels, shoveled flat, and the outside is covered with soil.
Watering, sealing pits
Immediately after planting, water the plants and drench them for the first time. If the trunks are skewed, they should be straightened in time and water should be poured every two days. Due to the fact that it is in winter, the second water is poured and the pit can be sealed after the water falls. We buried earth in a tree pit, and piled up earth mound more than about 30 centimeters around the ground, and we photographed.
Bracket
After pouring the water over the first time, the stand was erected. Each tree was used with three pine poles that were 2 meters long. Put a straw mat on the trunk 1.4 meters above the ground, put a pine pole every 120 corners, and dip the base of the pole into the ground at an angle of 45 degrees. The upper part of the pole is tied with iron wire on the mat, and it is tied and tied. The bracket can play a good supporting role for the big hedgehog so that it will not fall due to strong winds or other reasons.
