Description
Technical field
Transplanting and technical field of cultivation the invention belongs to ornamental plant, and in particular to a kind of humid region ground diameter is more than 20cm
Big tree, the method for transplanting of ancient and well-known trees.
Background technology
On the one hand the modernization of Chinese city drive ons the border of urban land construction boldly to wide range, the opposing party
Often there is Important Adjustment and change in face urban internal structure, urban construction, afforestation development are swift and violent, particularly afforestation
It is required that more and more higher, transplanting big tree, a night grows into forest is the requirement of afforestation, is also the direction of development, these cause nursery,
The many big tree in field（Diameter is in more than 20cm）And panoramic ancient and well-known trees are faced with the destiny for being transplanted and transplanting.
Chinese Regional is wide, and Difference of physical environment is very big, and humid region and arid biogeographic zone can be divided into from the differentiation of precipitation large scale angle, leads to
Normal humid region arboreal growth does not need irrigation management, and natural precipitation can sufficiently meet growing for trees, and arid
Area's ornamental trees and shrubs growth must carry out irrigation management（Except the raw trees of drought）, otherwise trees cannot normal growth development and survive.
The root growth of different region trees is different with development, the distribution space in underground, therefore transplanting tree is in different regions
Different to method for transplanting requirement, especially requirement of the transplanting big tree to technology is very harsh, as the saying goes " people moves work, and tree moves dead ",
Transplanting process is careless slightly to may result in forest death, is really also such in practice.In present city and road construction for
The various transplanting demands of big tree and ancient tree are a lot, and trees are transplanted transplanting almost all to be occurred everyday, for humid region, according to
Statistics, big tree（Diameter is in more than 20cm）And ancient tree transplanting survival rate is not very high, normally no higher than 70%, main cause：By
Then humid region, during root system development, root system is not influenceed by moisture, general shallower, the wide range of distribution of distribution,
It is mainly transporting root and support root near trunk part, absorption root is mainly distributed on the place away from trunk, currently employed shifting
Flitch method of planting trees is simple, is generally conventionally excavated, and the diameter of general root system soil ball is trees according to a conventional method
8-10 times of ground diameter, it is contemplated that the problem of carrying, general soil ball diameter is no more than 2.5 meters, the soil ball that such tree root is carried
Typically only transporting root and support root, absorption root is capillary root few, after transplanting, root system cannot timely and effectively absorb nutrient and
Moisture supplies huge aerial part, causes big tree dead or trunk is most of dead, and such transplanting scheme does not follow tree
Wood transplants the self-demand of trees, and transplanting trees physiological and biochemical activity can not normally be maintained, and moisture, nutrient can not have
Effect supply, so as to cause to transplant forest death；Due to being to set greatly and ancient and well-known trees, every plant of ten thousand to the hundreds of thousands of value 1 unit, so that
Cause substantial amounts of economic loss.This invention is directed to humid region, using special method, changes the above and causes to transplant trees
Dead principal element, by the method for being completely cured, is largely sprouted, afterwards again using digging before transplanting by stimulation trees absorption root of being completely cured
The method of pick is to tree digging, it is ensured that transplants tree root soil ball and includes substantial amounts of support root, transporting root and absorption root, greatly
The integrality for having saved root system from damage, so as to greatly improve transplanting tree survival rate, experiment survival rate to more than 95%.
The content of the invention
It is an object of the present invention to provide one kind of a kind of big tree of humid region ground diameter more than 20cm and ancient and well-known trees
Method for transplanting.The method changes the method for the big tree in humid region and ancient and well-known trees routine transplanting and causes the fatal of tree death to lack
Point, the key technology that wooden root system soil ball absorption root of planting trees lacks is moved down using technological break-through humid region environmental condition of being completely cured,
By being completely cured and intercepting promoting root growth technology so that form substantial amounts of absorption root in the range of soil ball transplanting, it is ensured that transplant tree soil
Comprising substantial amounts of transporting root, support root and absorption root in ball, the big tree in more than 20cm and the transplanting of ancient and well-known trees for diameter,
Using being completely cured and intercepting promoting root growth technology, formed and transplant the preferable soil ball that trees need, the physiology life for transplanting trees has been effectively ensured
Change activity and moisture, the demand supplies of nutrient, fortune are carried out transplanting big tree and achieve significant effect in Shanghai City in this way,
Transplanting survival rate is greatly improved.The method is simple and easy to apply, workable, survives with storage rate up to more than 95%, the method
Transplanted for the economical and effective of the big tree in humid region and ancient and well-known trees and provide new method.
Humid region ground diameter of the present invention more than the big trees of 20cm, a kind of method for transplanting of ancient and well-known trees follow these steps into
OK：
A propings：Trees proping to transplanting is fixed, and level altitude is according to the height of trees, size at 3-8 meters of trunk
Place, fixed using hard materials such as wooden and/or ironys, ground supports point at 3 meters from trees in addition, using 3-4 support frame
It is fixed, it is desirable to which that support two ends are fixed on ground and trunk, can not be swung as principle with trees after fixing.Stem sample site bearing
First wrapped up with materials such as felt and/or rubbers and fixed again, not damage bark as principle；
B is excavated：In any period in arboreal growth season, according to trees size, soil ball diameter is typically required in 2-2.6m, i.e., with trees
It is the center of circle, carries out vertically manually or mechanically excavating annular ditch groove by radius of 1-1.3m, in mining process, with the sharp weapon such as spade edge
The root system of the cut-out trees of the interior outside vertical of groove, groove width is defined by that can excavate cutting depth, is tried one's best during excavation
Ensure that the root system of trees side is complete, it is to avoid big disturbance, cutting depth 1.2-1.5m；
C materials enclose root：After groove is excavated, will with the impenetrable material of the tree roots such as width 1.2-1.5m iron sheets, plastics

Humid region, during root system development, root system is not influenceed by moisture, the wide range of distribution, is mainly near trunk part
Transporting root and support root, absorption root are mainly distributed on the place away from trunk；The depth of Root Distribution is typically shallower, because soil
Water content is big, and the permeability of soil is poor, and deep layer root growth and development is difficult；Currently employed transplanting trees method is simple, generally
Conventionally excavated, the diameter of general root system soil ball is 8-10 times of trees ground diameter according to a conventional method, it is contemplated that
The problem of carrying, general soil ball diameter is no more than 2.5 meters, the soil ball that such tree root is carried typically only transporting root and support
Root, absorption root is capillary root few, so causing that trees are bigger, soil ball is smaller, survival rate is lower, after transplanting, root system cannot and
When it is effective absorb nutrient and moisture supplies huge aerial part, cause big tree dead or trunk be most of dead, it is such
Transplanting scheme does not follow the self-demand that trees transplant trees, and transplanting trees physiological and biochemical activity can not normally be tieed up
Hold, moisture, nutrient are unable to effective supply, so as to cause to transplant forest death；Due to being big tree and ancient and well-known trees, every plant of value
1 ten thousand to hundreds of thousands unit, so as to cause substantial amounts of economic loss.This invention is directed to humid region, using special method, changes
More than cause to transplant the principal element of tree death, one be by the method for being completely cured, by stimulation tree root of being completely cured before transplanting
A large amount of to sprout, two is largely to form capillary root, absorption root in the interior survey for enclosing root timber material to fertilizer using root growth, and three is profit
With the extension transplanting tree phase so that transplant in soil ball comprising substantial amounts of transporting root, support root and absorption root；Afterwards again using excavation
Method to transplant tree digging, in combination with the science pruning method that the bright bud of trees is all wiped out with branch；Ensure that
Transplant tree root soil ball and include substantial amounts of support root, transporting root and absorption root, greatly save the integrality of root system from damage, so that
