Description
Technical Field
The technology belongs to the field of growth management of trees and relates to the work of repairing the bark defect of a trunk of a big tree.
Background
The trees directly and indirectly breed more than 95 percent of terrestrial animals on the earth, the forest regulates the climate, blocks the damage of strong wind, reduces the disasters of heavy rain, maintains water and soil, shelters the sun in sunny days, creates living environment for a plurality of plants and animals, but people walk to the ground from the trees, since the birth of people, in each period of the development of human civilization, the trees play a key and extremely important role for the human beings, one of the earliest tools of the human beings is made of a tree stick, the earliest weapon of the human beings is made of wood, the house which the human beings live at the earliest is built by the trees, the fire which is used by the marks of the civilization of the human beings is mainly made of wood as fuel, and also has the introduced wood drilling for getting fire, the yellow revolution of the human civilization marks is made of the majority of wood, and the metal smelting of the human civilization marks is made of wood, coal as fuel, the black powder invented by human beings is charcoal, the starting point of human industry modernization is based on industrial grain coal, the earliest vehicle of human beings is a car made of wood, the first bridge of the river made by human beings is a wood bridge, the first bridge of the river made by human beings is a wood boat, the human beings conquers the rivers and oceans and uses the best articles of wood furniture, the best paper of the modern times is wood pulp paper, the human beings ask for the trees endlessly, and take a cool place by leaning against the big trees all the time, only want to make a living house for the human beings, and want to grow a good living environment … … for the human beings, but because of asking for and hurting of the human beings, the growth of the big trees is far less than the disappearance of the big trees, the long-lived trees are fewer and less, and more prominent in cities.
Street trees, square trees and courtyard trees become the favorite of pedestrians and leisure people, and particularly, larger trees, trees with more shady shades in summer and ancient trees with commemorative significance are popular with people. But urban trees are most damaged by three types; firstly, the trunk is artificially injured, the street trees are injured most artificially, the most injured parts are barks of trunks which are quite high as people, the more the trees are, the more the artificially injured trees are accumulated, the vehicle collision and the instrument collision exist, (the trees in other places are injured little, and the forests hardly exist) at present, the street trees basically depend on the growth of the street trees and the restoration of the street trees, after a plurality of trees are seriously injured, the barks cannot be folded, the wood parts of the trunks losing the protection of the barks for a plurality of years begin to rot, the trunks of some trees are rotten to be hollow, and the serious trees die. Secondly, the tree still receives the harm of insect pest, especially street tree and the square tree that is hot, because people's heat is very loud, almost has not had the natural enemy of insect pest, and urban tree insect pest is managed by afforestation personnel completely, in case the management is interrupted or neglected, serious insect pest also threatens the growth of trees, and often people find that big tree has the insect pest, and the trunk branch has been eaten away by the worm, and more has the strong wind to scrape big tree trunk or big branch and has been cut off, just sees that the rupture department is eaten away by the worm, even people find the insect pest, also sprays the pesticide and kills the pest, also has no way to the trunk that moths is empty. Thirdly, when the big branches are blown off by wind and are artificially broken, and dead branches naturally eliminated at the lowest part of the crown of the big tree are not repaired by people in time, the broken branches are cleaned up and left, so that the bark at the broken branches cannot grow tightly, and the branch core starts to rot at the position for a long time every year and is rotten to the center of the trunk; and the branch remained after repairing the big branch is too long, the branch is withered early, but the branch does not fall off, and the bark cannot grow tightly, so that the branch is rotted from the withered branch until the branch reaches the center of the big trunk. All cities are present for these three points.
The sycamore street trees in Nanjing are many, and are the earliest cities planted in large scale in China, many sycamore trees have the growth tree ages of 90 years, because the sycamore trees have strong self-repairing capability, many people define that the sycamore trees are resistant to pruning and the king of the street trees, so the sycamore trees are damaged, the sycamore trees are pruned every year, only the sycamore tree enjoys the 'stand-by', the sycamore trees in several main streets in Nanjing are pruned for several times in one year before reform is opened, firstly, the sycamore trees are shaped like, secondly, the main streets in Nanjing are also the main wiring paths of various lines, various lines are basically arranged in a row with the sycamore street trees, the phenomenon that the big trunks of the sycamore trees are all provided with several big branches, the middle of the big branches are various lines, (the existing lines are switched to the ground, and the individual local sub-street trees in three mountains also have one section of electric wires), the common electric department participates in tree trimming every year, the standard of the tree trimming is that which branch is sawed off when touching a wire, even a strong wind is scraped, a person needs to be sent to patrol once, branches with the wire touching are immediately removed, the telephone line arrangement is also the same, the garden department repairs the trees mostly according to the crown, all tree trimmers have high and low trunk technical levels and large responsibility centers, the bark is damaged too much by some tree trimming, the bark is repaired too large, the stumps left by some sawed branches are too long, the diameters of the sawed branches are too large, the barks cannot grow the bark, the exposed wood parts begin to rot for a long time, some trees rot to the center of the trunk, so that the big ballwood trees in the main streets in Nanjing have much rotten cores, the streets are green tunnels when the streets are far away, and the trees are nearly seen to have scars, some big trees are completely rotten to be empty, big trees which are eliminated due to rotting or big branches which are sawed off in the year exist, cement is poured into the holes of the rotten core of the big sycamore (the same method is also used in many cities) at present, plastic foam is used in other methods, the bark cannot be folded by the two methods, the appearance is good, the cement absorbs moisture when meeting rain, the moisture evaporates when meeting the weather, the cement also contains chemical components which have influences on sap in the trunk, a gap exists between the cement and repaired hole wood, some cement cracks to form a gap, rainwater seeps into the wood trunk of the big trees, the plastic foam is too soft, the bark cannot be supported by the plastic foam to grow, and the trunk and branches cannot bear load, so that the big trees cannot be completely saved.
All organisms on the earth are organisms wrapped by skins, the circulation and the propagation of the organisms are completed in an organism wrapped by skins and protected by skins, any organism cannot be called as a complete or normal organism once the skins are broken, the barks have the protection effect, the circulation function of upper and lower liquid and the unique growth function of trees, all roots, trunks and branches are grown by the growth layer of the barks, no bark wood layer can not grow, the tree circulation without the skins does not exist, and the only standard of life is the circulation of the organisms.

Detailed Description
The invention adopts the method of repairing the bark lacking of the trunk by the live bark, namely repairing the defective bark and forming a complete big tree by the big tree, in the determined collected bark blocks for repairing, the upper part of the bark block is cultured in advance to grow branches, the lower part of the bark block is cultured in advance to grow tree roots, and the bark is the bark with branches and roots, the bark block can be used for repairing the defective bark, the bark block is embedded into the defective bark and can grow circularly, the surrounding bark of the bark block is tightly combined with the bark for repairing the trunk, the bark of the trunk and the repaired bark block grow and fold into a whole in the later growth, then the branches and the roots on the bark block are gradually removed in different times, and the whole trunk of the big trunk is repaired by using the live bark.
The method of repairing the bark of the trunk by using the live bark is adopted, the tree which can be cut is selected, for the tree which is to be eliminated, the rotten tree is hollow, as long as the bark is live and thick in a wood layer, the tree can be used, the big branch which is to be sawn off is prepared, particularly, the big branch of the big tree to be repaired is best, a certain bark is selected, the branch is cultured and grown on the upper part of the bark, the root of the tree is cultured and grown on the lower part of the bark, the bark is changed into a live bark block with root, branch and leaf, and the bark is cut off to repair the defective bark of other big trees;
A. selecting a tree to determine the bark blocks adopted; selecting a tree which can be cut into bark or a big branch to be sawed off, selecting the grown bark, determining the size of a bark needed for repairing, and making a full record and necessary brands. 1. Selecting bark blocks and making full records for facilitating later work, and according to the foundation and the summary experience, the varieties of trees are many, and the characteristics of all the trees are not all the same; 2. the barks of a plurality of trees never fall off, so that dead barks of old barks are removed completely, and the range of the dead barks is larger than that of determined bark blocks; 3. the trunks are all round, and the shape of the bark blocks selected and cultured is basically consistent with that of the trunks to be repaired; 4. selecting eliminated trees, wherein all trunks are hollow, the tree can be processed as long as good barks exist, and the eliminated trunks can be made into a plurality of bark blocks; 5. the big branches to be eliminated are selected, some big branches must be trimmed, and the branches can be made into a plurality of bark blocks, and the radian of the appearance is required to be consistent.
B. Culturing long branches and leaves on bark blocks; the determined bark block is best provided with branches, the upper edge of the bark block is 2-5 cm lower than the upper edge of the bark block when the bark block is not in spring and autumn, a bark cutting groove with the width of 3mm and the length of 20mm is cut by a knife or the bark is cut into a cross shape by a knife, the length of the bark cutting groove is 10-20 mm, the depth of the bark cutting groove is 3mm below a wood layer, the sun does not need to be shined at the bark cutting and cutting position, long branch leaves on the bark block are cultured until the sum of the areas of the leaves on the branches is more than 10 times of that of the bark block, and more branches are cultured on the. The life of the tree is the leaf, a certain amount of the tree is needed, the branches are cultivated firstly, different methods are selected according to different tree species, and observation is needed after the bark cutting and the bark cutting are finished.
C. Culturing the lower long root of the bark block; selecting spring and autumn, drilling 2-5 cm on the edge below the bark block (vertically below the branches), clamping a drill bit with the diameter of 10mm by a pistol drill, drilling 10mm in parallel, drilling more holes when the determined bark block is large, blocking sunlight at the hole opening, keeping the periphery of the hole moist, wrapping fertile soil in time when the roots grow out, hanging the fertile soil at the hole opening, enabling the grown roots to go deep into soil, increasing the lengthened soil package according to the long roots later, shading the soil package in summer and not sunning the sun, preserving heat in winter and not freezing, and enabling the roots to be thick and long until the sum of the lengths of all the roots is 1.5-2 times of the length of the branches. All water of the tree is absorbed by the roots of the tree, bark blocks serve as an independent tree culture, the tree is various in types and different in species, the principle of culturing the roots is the same, rooting powder can be scattered after the holes are punched, openings of the holes shield sunlight, and the moisture keeping and the soil wrapping are created for the roots and the roots.
D. Culturing the bark blocks to grow independently; when the branches on the bark blocks are 15 cm long, more than 6 leaves are provided, and the roots are 10 cm long, the determined sizes of the bark blocks are enlarged by 1 cm on the left side and the right side in the transverse direction respectively, then 1 cm of bark is cut off, when the branches grow to 30 cm long and the roots grow to 20 cm long, one third of the bark is cut off, the positions of the bark blocks are increased by 1 cm above and below the original determined sizes of the bark blocks respectively, then 1 cm of bark is cut off, when the branches grow to 40 cm long and the roots grow to 28 cm long, one third of the bark is cut off, and the other third of the bark is left, so that the bark blocks can independently and circularly grow on the roots and the branches on the blocks. The method is characterized in that the independent growth of bark blocks is cultured, the bark blocks are independent to promote the roots and leaves on the bark blocks to grow quickly and to grow long, the bark blocks circulate independently, bark cutting and separation are gradual work, the growth is carried out early according to the growth conditions of the leaves and the roots, the color of the bark is observed after the bark cutting, the color of the bark reflects the growth quality, more bark is cut after the bark is grown, and the quantity of bark is reduced otherwise.
E, (I) digging and embedding grooves at the defective bark; the damaged bark is completely removed, grown live bark is cut to be exposed, the cut bark is in a shape of a circle, an ellipse or a rectangle with a round corner, a wood layer is dug to be 1.5-4 cm deep according to the shape to form an embedded groove, the surfaces around the groove are cut to be neat, flat and smooth, the bottom surfaces are parallel and have no height, the bark and the wood layer cannot be separated, and old dead bark around the groove is removed. The embedded grooves are pits and roots of the bark blocks, after the periphery and the bottom surface of each groove are contacted with the wood of the bark blocks, sap can mutually permeate and circulate, no gap and no cavity exist, otherwise, the sap can not mutually permeate and also can be retained, certain cutting is good, a used cutter is used for cutting once, the cutter can not repeatedly scrape the cut surface so as not to damage wood cells, and the following moving cutters work the same.
(II) treating the defective bark with a cavity; the damaged bark is rotted into a deep cavity, the cavity is filled up, the cavity is cleaned, the cavity wall is processed to be smooth and disinfected, the cavity is made of plastic into a pocket and placed into the cavity, cement is filled into the plastic pocket, the cement is sealed at the position 4 cm away from the bark in the cavity, the cover is smooth, the bark and a wood layer are vertically cut around the cavity, and the reserved space is easy to place bark blocks. The bottom surface is made of plastic, so the periphery is cut and matched well later.
Cutting bark blocks with branches and roots; the leaves and the roots of bark blocks meet the requirement of B, C, the bark with branches and roots is cut off together with a wood layer according to the slightly enlarged shape of the cut bark blocks, old and dead bark which does not play a role in growth is removed, the thickness of the wood layer is 2-4.5 cm, the bark cannot be separated from the wood layer, the wood layer is not cracked, leaves are removed by 80%, the tree roots of branches are kept intact, the tree roots can not be damaged, the periphery of the bark with the wood layer and the plane of the wood layer are carefully trimmed, the peripheral size and the embedding grooves are particularly matched with each other closely, the bottom plane and the plane of the embedding grooves are parallel, the depth error of the wood layer is not more than 2mm, after the bark blocks are determined completely, the bark blocks which are repaired are in contact with each other in a tidy mode, and butt joint are matched. Bark and wood layers cannot grow alone, two pieces must be combined to grow, and the larger the tree, the thickness of the wood layer is to be preserved, what is called bark pieces, bark, which are cut off from the wood layer with bark
The wood layer can not be separated absolutely, the bark block is cut by amplifying 1-2 cm according to the size of the embedded groove and then repaired finely to reach the matching size of the embedded groove, the thickness of the wood layer can not be too large in error, the wood layer can not grow, and the butted wood layer is long foreverBut not together, the butt joint can only obtain the mutual permeation of sap, the bark grows a new wood layer only by the good combination of the bark in the future, and the bark is specially straightened and butted after the bark blocks are embedded.
Repairing bark blocks at the cavities; the plastic plane of the hole repairing needs to be flat, no gap is formed in the periphery of the tree hole, all gaps are filled with the user-shaped glass cement, the bottom surface of the hole is made of plastic, the periphery of the hole is also cut into a wood layer, the bark blocks are placed in the hole to be in close contact, the bark blocks are in close contact, and the height error is not more than 2 mm. The glass cement can be applied to the uneven bottom surface, so that the contact surface has no gap or cavity, accumulated liquid is avoided, the periphery is in good contact, and the bark is in good contact, so that the bark is beneficial to the growth of the bark and the mutual seepage is integrated.
G, (I) fixing the bark blocks; the diameter of the trunk is less than 50 cm, the embedded bark blocks are less than 200 square cm, the thickness of the wood layer is less than 2 cm, the trunk is bound by a metal throat hoop or a rope, and small sticks are placed at the bark blocks to improve the pressure on the bark blocks; the bark blocks with large area and wood layer thickness of more than 2.5 cm can be fixed by long wood screws, a circle is arranged around the bark blocks, the distance between the periphery of the bark blocks and the edge of the bark blocks is 2-3 cm, a wood screw is fixed at the interval of 5-10 cm, the length of the wood screw exceeds 2 cm of the bark blocks, holes are punched on the bark blocks, then the wood screw is arranged, the head of the wood screw can slightly press into the bark, and the bark and the wood cannot be laminated and cracked. The wood layer can not grow, the butt-jointed wood layer is two bodies forever, the embedded bark block is fixed only by adding, the bark block is ensured not to be loosened, two barks grow into a whole in the growth process, the integrated wood layer grows out again, the wood layer grows thick, the bark block is stable, fixing devices such as a hose clamp and the like are only dismounted, a wood screw does not need to be dismounted, the bark can wrap the wood screw in the future growth process, and the wood screw is galvanized or stainless steel.
(II) fixing the bark blocks for repairing the holes; the bark block is big, adopts long wood screw fixed, breaks through the bark block with the drill bit earlier, trades the percussion bit again and punches the hole depth 3 centimetres above with the cement layer, and the diameter in hole is less than wood screw external diameter, blows the hole clean with the air pump, and downthehole glass that pours into glues, and reuse wood screw or self tapping screw are fixed firmly. Because the bottom surface of the cement is needed, a percussion drill bit is used for drilling a cement hole, the cement slag is blown clean by an air pump, the circulation of the sap is not influenced, the glass cement is injected into the cement hole to achieve sealing, and the sap cannot seep into the cement.
H. Growing and nursing; the branch leaves on the repaired bark block can shine the sun, the branches on the original tree are pruned when necessary, the soil bag is fixed firmly on the trunk, the soil bag needs to be lengthened when the roots grow, secondary water is added for several days, the soil is kept moist, the soil bag can not shine the sun, the growth condition of the bark is observed regularly, fixing devices such as hoops are intact, the branch leaves on the trunk on the bark block are kept to grow vigorously particularly, the branches and leaves on other places can be pruned, the fertilizer is applied to the roots on the same side, and the branches and leaves on the bark block are highlighted vigorously. The bark blocks are ensured to be circularly alive, the growth requirement of the tree is required to be ensured, leaves on the bark blocks can be fully sunned, other branches and leaves are trimmed off when necessary, roots on the bark blocks fully absorb moisture and nutrition, soil bags are kept moist, in addition, the roots on the side, where the bark blocks are embedded, of the repaired big tree are supplied with more water and fertilizer, branches and leaves on the side are kept in vigorous growth, and the circulation of the tree (the branches and leaves do not cover the branches and leaves on the bark blocks) is vertical up-and-down circulation, so that the bark on the side grows fast, and the growth of the bark blocks is fast.
I. Performing later-period management; the tree species which grow fast grow in the second year and the tree species which grow slow grow in the second year can be folded in the third to fourth year, the soil bag is gradually watered a little by a little after being folded, finally, watering is not carried out, the roots are sawed off by the tree species along with the dried roots, the branches are sawed off at intervals, the hoop or the rope can be disassembled, the wood screw is not moved, and the wood screw can be wrapped in by the tree species which grow fast grow in the later year. When two types of barks grow into a whole, devices such as hoops and the like can be gradually removed, the roots and branches are cut off close to the barks, the barks grow tightly, and after the hoops and the like are removed, the positions of repaired bark blocks, particularly street trees and plaza trees, still need to be protected.
The bark is equal to the life of the tree, the bark is intact, namely the tree is intact, and like all organisms, the bark plays a role in protecting the integrity of the tree and has the function; the bark has the unique growth function of trees, the bark wraps the roots of tree trunks and enables the tree trunks to grow big and thick, and the trees stop growing when no bark exists, so the bark is protected firstly, the bark has strong self-healing capacity, so that many forests in the world, and many trees in the forest are grown vigorously and naturally and grow, and have the natural elimination function, when the trees grow big and high, the small branches with bad growth and the branches growing early become the branches which cannot be exposed to sunlight at the bottom of the tree trunks and can be eliminated naturally, the branches can automatically fall down after the leaves do not dry up again, and the bark can automatically grow tightly at the gap parts of the fallen branches, so the seen big trees are all smooth and intact from top to bottom, forest trees have a long life and are still grown well for thousands of years.
However, the city tree has no good 'life', firstly, the city is busy, people come and go, the bark of the trunk of the street tree plaza tree is most damaged artificially, the part with the most damage is the bark of the trunk which is quite high with people, and the trees are accumulated to be more damaged artificially when the trees are larger and instruments collide with each other; secondly, the tree is also harmed by insect pests, particularly street trees and busy square trees, and almost no natural enemies of the insect pests exist due to the people's busy; thirdly, improper maintenance, management and branch repair are realized, taking the Nanjing big sycamore as an example, the Nanjing big sycamore which is not repaired or called as a shape-repaired big sycamore is not repaired in the southeast countryside scenic area and the Yuhuatai spirit park in the Nanjing basalt lake, the grown high-lobar trees are straight, smooth and round, the Nanjing major streets are distinguished as pride big sycamore, the far distance is a green tunnel, the nearly trunk almost bears scars and dies with rotten and hollow big trees, the rotten tree holes are fully blocked with cement, the trunk is good, the false bark is not alive, and the cement-repaired tree holes continue to rot only slowly.
The method for repairing the bark lacking of the big trunk by the live bark effectively solves the problem of the bark lacking of the big trunk, the method still follows the growth rule of the tree, the growth requirement of the tree is met, the bark lacking of the tree is repaired by the bark block which is not separated and is formed by the wood layer and the bark together, all the barks of the trunk are intact, are circulating corium, are the bark growing continuously, and are the same as all the barks, and the trunk is longer and thicker.
