; Big tree transplantation method and treatment The first section of soil ball transplantation technology And handling 1. Preparations before digging big trees Main tools: 1, shovel and Shovel 2, hoe or pick 3, grass rope, draw rope, sling 4, tree pole guard, cork pad 5, hand saw vehicle preparation: 1, crane 2, transport vehicle If conditions permit, for crown shape Too big trees can be properly pruned first, mainly cutting off the inner branches, diseased branches and unwanted old branches and weak branches. In order to reduce the amount of canopy, it is convenient for hoisting and transportation, and the consumption of nutrients is reduced.
Second, the construction process of excavating large trees
excavating large Technical points of the tree: 1. When digging, take the trunk as the center and draw a circle 3-5cm larger than the calculated earth ball 2, follow the circle drawn and dig the soil outward, the width of the trench is 60-80cm 3, the height of the soil ball is generally 60-80% of the diameter of the soil ball ; 4. For fine roots, you can use a sharp shovel or spatula to shovel directly 5. Thick roots must be cut off with a hand saw. Do not use other tools to hardly break and tear 6. After the soil ball is basically formed, trim the soil ball smoothly to facilitate bandaging 7. When the soil ball is trimmed to 1/2, the bottom is gradually closed inward, and when 1/3 is received, a flat bottom is trimmed at the bottom, and the entire soil ball is in the shape of a rounded truncated cone. 8. Before digging, you can pull rope or sling according to the situation to ensure safety 9. The diameter of the soil ball is generally 8-10 times the diameter of the tree at breast height < br />
10. Ditching. The width of the ditch is generally 60-80cm 11. The height of the soil ball is generally 60-80% of the diameter of the soil ball 12. Fine roots can be directly shoveled off with a shovel or a shovel. Be careful not to damage the cracked roots 6. For the thick roots of tall trees, wait for the crane to lift them before sawing off
3. Soil ball correction
Key technical points: 1. Try to maintain the integrity of the soil ball and not loose it 2. When the soil ball is half of its height, go inwards Retracted to 1/3 of the diameter 3. Flatten the edge of the earth ball to make it smooth and easy to tie the rope
4. In the end, the whole soil ball should be in the shape of a "rounded platform"
Repairing the soil ball with "burrs" is conducive to bandaging ;The repaired "inverted cone" type soil ball
Fourth, the key technical points of root treatment:
< span>1. Spraying roots with root power ① 200 times can induce rapid rooting of big trees 2. Spraying soil balls with "Gen Ling" 600 times to prevent disinfection Root rot 3. Spray the whole soil ball, re-spray the root cut surface and fibrous root fine root system 5. Bundling Soil ball Key technical points: 1. The base of the tree is tied with a grass rope nail guard for protection Trunk 2, "waist hoop", generally tie 8-10 loops of straw rope 3, the rope tying requires tightness Appropriately and evenly, Bundle 60-80cm tall grass rope at the base of the big tree, nail the guard board on the grass rope to protect the trunk, hit a waist hoop, tie 80-10 loops of grass rope to tie the soil ball, orange type or chicken cage type when binding Evenly, tightened, and partially embedded in the soil, the rounded truncated cone-shaped soil ball bundled in the soil
VI. Lifting the big tree p> Key technical points:
1. Cut off the thick roots. Before cutting the roots, you must first use a crane to hold them < br /> 2. Determine the lifting position; determine the lifting position according to the weight of the tree crown and soil ball, and make the center of gravity of the big tree below the lifting position
3. Lifting Part damage prevention treatment: ①Tie a 60-70cm straw rope on the hoisting part ② Nail the same height and evenly distributed wooden boards on the straw rope to protect the tree trunk
4. Lifting: the steel rope Tighten the hook or soft strap on the wooden board (note: prevent the steel rope from breaking when hanging the tree). Bundle the grass rope guard board at the lifting place and trim it properly, Pull inside the lifting part and fasten the steel rope, pay attention to the safety of lifting
Seven, loading and transportation
Key technical points:
1. When hoisting, try to avoid damage to tree bark and soil ball
2 When loading the car, use a soft rope (as shown in the picture) to protect the bark
3. When loading the soil ball, please be careful and put it softly under the soil ball. Soil or straw rope to prevent the earth ball from being scattered
4. The contact between the trunk and the rear deck must be supported by cork
5. Use cork or sandbags to support both sides of the soil ball in the cart
6. The crown of the tree should be higher than the ground during transportation to prevent damage to the crown of branches, and pay attention to the damage caused by the branches during transportation.物
7. The road conditions are not good. You should drive slowly and carefully. Use cork and soft cushions (straw rope, straw bale or soft rubber skin can be used) to cushion the trunk with a soft rope to make soil The ball is firmly fixed, with cork sandbags on both sides to prevent rolling, and transport carefully. The speed should be controlled at about 20 km/h. For long-distance transportation, water should be continuously sprayed and a tree power bottle infusion should be inserted to supplement nutrients and moisture. < /span>
8. Transplanting and planting and treatment
Select the orientation to place the tree and place the tree Straightly remove the soil ball wraps such as grass ropes to prevent water and retting roots Coarse soil to facilitate ventilation and use support and tie rods to stabilize the tree
Key technical points:
1. Holes in the trunk must be crossed and staggered, and the holes are required to be smooth and have little damage.
2. After the liquid is injected, if you need to add water to the tree, you should add water immediately, and there should be no empty bottles or empty bags.
3. After the injection, the needle should be removed immediately, and the empty bag or bottle should not be hung for a long time.
4. The orifice must be brushed with "calligraphic film" in time to sterilize and disinfect the orifice to promote healing and prevent air from entering the tree.
5. If you need to hang again, you should re-punch, water the root water, you can add Guoguang root power to use the suspension needle injection and tree power to activate cell viability and promote budding Promote.
