Abstract

The invention relates to a speed-up method of a thick living ancient tree, belonging to the fields of sightseeing agriculture and landscaping. A living ancient tree with the trunk thickness over 2m, the height over 6m and the crown width over 8m comprises the following three parts: a hard rigid material tree core, trees planted on the periphery of the tree core and trees planted in a pit at the top of the tree core. The tree core made from steel reinforced concrete or other hard rigid materials is cylindrical, medium-size trees longitudinally split from the trunks to rhizosphere soil balls are planted on the periphery of the tree core, partial core wood is removed from the longitudinally split trees so that the longitudinally split trees are in arc shapes, and the adjacent left cortex andright cortex of each tree are straightly cut up and down to be tightly connected into a whole trunk. The tree keeps original twigs and new trigs growing after plantation, the pit is preserved at the top of the tree core, the medium-size trees of the rhizosphere soil balls are planted to extend upwards and around to form a gigantic crown of the thick living ancient tree.

Description

A kind of thick ancient tree express method alive

Technical field

The invention belongs to afforestation, sight-seeing agriculture field.

Background technology

Prior art can only be transplanted the big tree below the diameter of a cross-section of a tree trunk 1.3 meters above the ground 1m, and need to uproot be about native bulb diameter 1.5m, will guarantee that also native ball is complete in the loading and unloading transportation, soil block is not scattered, otherwise, transplant be difficult to into alive.The Chinese Central Television's thick transplanting tree survival rate in the seven cover domestic many cities of report is lower than 50%.Given this and to the former ecological environmental protection purpose vegetatively of big tree, limit thick transplanting tree various places.Change news from Xinhua News Agency " Xi'an evening paper " on May 8th, 2006, and to some urban afforestation, the leader of nation-building portion " requires firmly to prevent big tree ancient tree ... guaranteed not survival rate, causes huge fund and ecological waste.”

Color century city is grown in order to view and admire needs, with the bionical false ancient tree of concrete for making like Xing Shansi street, Xi'an, the Eastern Jin Dynasty Land of Peach Blossoms, Chang'an Shang Wang village's Peasants Joy and Jilin in some places.Number of patent application 01133669.2, its trunk surface are concrete, do not possess the general features of ancient tree trunk.

Someone plants a plurality of small-sized trees in one clump, and the bark of joint, front and back cuts away and makes joint together, becomes a whole big tree behind the generation callus.Its existing problems are that the tree thickening growth meeting of group planting central authorities is squeezed to such an extent that peripheral tree is scattered here and there; Tree crown is little, and about diameter 5m, group planting becomes thicker tree, also is difficult to transplant.Number of patent application 200310111468.X is from the sowing beginning, and the seedling distortion is woven into netted, and be abutted against the intersection, needs to form netted trunk through for many years, does not possess the express method characteristics.

In the Tian Wenjie of Xi'an State Forestry Administration, P.R. China " Xi'an ancient and well-known trees " book several strains ancient tree in thousand is arranged, the vacancy suffers fire in the trunk, retains epidermal thickness 1520cm.The strain Chinese honey locust ancient tree in 2 years is transplanted in Xi'an " Chinese Tang Yuan ", and trunk hollow is retained the about 20cm of epidermal thickness." Chinese businessman's newspaper " in March, 2006 news picture report, Qi Li village, Ankang city thousand " loblolly tree king " (gall nut), a brood of number of people honeybee in vacancy in the trunk before 10 years, the villager burns one day one night, the remaining half-turn of trunk, tens centimetres of thickness, annual so far branches and leaves are luxuriant.

The vital movement of trees, conduit upwards transports moisture and inorganic nutrients in the outer field primary xylem of dependence xylem, and the secondary xylems of the overwhelming majority just play a supportive role; Screen casing in the primary phleom under the trees dependence appearance tertia transports the organic nutrient of blade manufacturing to root.So, keep about trunk appearance thickness 20cm, just can guarantee trees vitality.A bough and a big root of perennial trees relatively independently exchange nutrition up and down; Between this separate unit because growth conditions is different; The growth force is also different, and in the course of time, vigorous corresponding bough, the big transport channel of root in trunk increase thick more and apparent rib shape.The ancient pear tree in Dunhuang, the ancient ginkgo picture in Chang'an all show rib shape trunk in the nineteen eighty-three Sun Yun of Shanghai science tech publishing house luxuriant " Chinese fruit tree history and the fruit tree resource " book.

Summary of the invention

The present invention mainly solves green lands such as sight-seeing agriculture scenic spot, ancient culture tourist attraction, park, garden for building the technical problem that the ancient culture atmosphere is planted thick ancient tree alive.

The present invention is thick, and ancient tree express method alive is realized through following technical scheme.

Thick ancient tree alive is to remove tree crown by some medium-sized trees saws; And will do to root soil ball from middle vertical profile, enclose and plant a circle, incision directly makes close proximity on the cortex of adjacent trunk; The callus that both produce merges together each other, and enclosing the wood of planting trees becomes more regular thick trunk.

Form cylindric tree core with hard rigid materials such as armored concrete or bamboo and wood, metals, as the dependence of enclosing the wood of planting trees.1m left and right sides dell is reserved at tree core top, several strains of planting upwards and to around extend medium-sized (rugosity 30～50cm) trees prop up as the middle rough segmentation of thick trees, totally form more than the high 6m the very large tree crown that fabric width 8m is above.

The vital activity of thick trees embodies through following approach: enclose and plant the medium-sized tree root frenulum soil of vertical profile ball; The ecological condition that keeps root system in the native ball; Make and continue to absorb moisture content, inorganic nutrients top needs contentedly; And root system stretches out from native ball and penetrates in the planting-site soil, incorporates for a long time in the planting-site ecotope; Enclose the wood of planting trees and go up the more original sprigs of reservation, make its continued growth; Enclose the wood of planting trees and go up the new twig of kryptoblast or indefinite bud germinating, keep some continued growths; Be difficult for the trees of the new twig of germinating, adopt subcutaneous stem grafting method, some twigs of grafting germinate and are new twig.Near two vertical profile trees were joined otch, germinating or grafted branch germinate new twig, and be favourable to healing of wound.These lived twigs can normally bloom, the result.

If the vacancy medium-sized trees of a strain of planting in advance in hard rigidity tree core, both go up the thickening growth space of a century leaving after at a distance of about 0.5m.

The embodiment of the ancient characteristic of thick trees is done, the very large tree crown, can also be made and enclose the wood of planting trees and leave vertical shape hole with hard rigidity tree core except that fat tree, is interlinked to the outside demonstration trees ancient in making; At hard rigidity tree in-core wall, the trees heartwood of removing when pasting medium-sized trees vertical profile, and, paste the sawdust of glue fusion at the wood surface of pasting or directly at hard tree wicking surface, more show the hollow rotten shape of ancient trees.

Advantage of the present invention is to plant and make more than the trees trunk diameter 2m, and more than the height of tree 6m, the very large ancient tree that tree crown fabric width 8m is above is equivalent to a bimillennial age of tree.Because be that a plurality of medium-sized trees are formed, the medium-sized tree root of every strain has less native ball, so it is easy to operate to plant, survival rate is also high, and making green land have ancient tree becomes possibility.Implement before trees germinate spring, and trees germinate, branch out in tens days, and the medium-sized trees of planting in tree core top also have a part the flowers are in blossom puts.Ancient tree alive in thousand appearred in tens days.

Embodiment

The case study on implementation shown in accompanying drawing and in the High-Tech Development Zone, Xi'an, a kind of thick ancient tree alive provided by the present invention is planted and preparation method, comprise that the tree core is made, the outer corral of tree core is planted trees wood and tree core top hole trees three parts of planting.

The tree core is made into cylindric 3 with armored concrete, high about 3m, and dried highly definite to enclose the ebon of planting trees, thickness is not less than 20cm.Hard rigid materials such as also available bamboo and wood, metal are processed.

Cylindric hard rigidity tree core can be trapped among around the existing medium-sized trees in original place or the tubular tree core central authorities medium-sized trees of a strain of planting, forms and mix the tree core.Tubular tree core supplies century-old thickening growth space on the central trees apart from the about 0.5m of central trees.

Enclose the wooden root system of planting trees and have native ball 1, cut two halves open with saw up and down from doing to root system soil ball, and remove the wooden heartwood of part, make into arcuation 2, enclose and be planted in cylinder and set around the core 3.Incision is straight on the adjacent trees cortex, makes mutual close proximity, does so that healing becomes full tree.When transplanting the vertical profile trees, keep original sprig 6 as far as possible, make its continued growth.

Cylinder is set core and is enclosed the wooden same position of planting trees, and leaves hole 4 and is interlinked to the outside.Timber pasted by tree in-core wall and glue closes sawmilling 5, covers hard material surface.

Tree well 8 is reserved, the upright and oblique medium-sized trees 7 of planting in cylinder tree core top.Dagger can be found in the oblique medium-sized trees of planting two or three meters that stretch out.
