The branches and leaves trunk 11 at top carries out misty sprinkling moisturizing, after metasequoia root system development is complete, stops top limb moisturizing, is changed to periodically
Root irrigation.
Big specification metasequoia complete crown plant construction method is described below in detail.
Metasequoia is deciduous species, in the fall when metasequoia be in fallen leaves state, absorb that moisture is few, and vital movement is mainly underground
Root growth, and start rudiment in spring metasequoia, water consumption is larger, and therefore, autumn transplants metasequoia high survival rate and plants in spring
Metasequoia is planted, the present invention preferably carries out metasequoia plant in the fall.
In addition, this method for planting be applicable not only to metasequoia plant, apply also for metasequoia belong to root of Roundfruit Licorice plant, transplanting,
Maintenance.Such as: China fir, Taiwan China fir, Taiwania flousiana, Taiwania cryptomerioides, cryptomeria, yew, parasol pine, Japanese cedar, bald cypress, Mexico fall plumage
China fir, taxodium ascendens, big tree, sequoia sempervirens etc..
In step sl, place adjustment is carried out first, and before construction, the sundries for being unfavorable for metasequoia growth to growing area is carried out
Removing, grasp groundwater level and surrounding soil property water content, organic matter situation simultaneously carry out draining, water storage work according to periphery landforms
Make.Then design idea is conveyed according to design drawing, illustrates and build landscape style standard, seedling is selected to metasequoia, tests seedling, trimming, cultivation
It plants and late maintaining carries out work and tells somebody what one's real intentions are, implement details preparation.
In step s 2, metasequoia nursery stock preferentially choose branching-point it is lower, it is tree-like it is well-balanced, growing way is preferable, plant root is complete,
The nursery stock of fibrous root prosperity.When metasequoia is shade tree, nursery stock branching-point is consistent, and primary and secondary branch branch is uniform, and whole height is approximate,
Side shoot reaches three-level branch or more.Branches and leaves are luxuriant at the top of limb, and the abundant metasequoia of greenery is preferable as plant is introduced.
Since metasequoia winter insect pest multiparasitization is on limb, autumn insect pest starts to breed and lodge, in step s3,
Branches and leaves and worm's ovum with disease pest are wiped out emphatically when before plant to digging nursery stock, the disease pest branches and leaves cut will be cleared up in time, transport
It concentrates and destroys in scene.To be unfavorable for the deadwood of metasequoia growth, sick branch and to as shade tree when cannot be formed it is unified
Limb will be trimmed together, determine metasequoia whole height, branching-point position, deadwood rudiment branch of erasing.Keeping metasequoia whole
Metasequoia internal branch is pruned off in the case of moulding, metasequoia, which trims appropriateness in the case where guaranteeing whole crown type state, ensures that metasequoia branch needs
Water fibrous root energy normal transmission.In addition, metasequoia nursery stock must obtain the quarantine quality certification that quarantine departments are provided.
The planting soil layer for carrying out metasequoia plant must be connect with sub-surface, to keep permeability inside soil.In step
In S4, planting soil layer is dug to when requiring depth still waterproof, should dig impermeable stratum, then backfills planting soil 5 to requiring depth
And it is steady and sure.The soil for being not suitable for planting plants in planting technique depth 1.5m must take soil removal and replacement measure, should be compacted after soil removal and replacement, make soil
Earth compactness is up to 80% or more, in order to avoid metasequoia root regeneration, growth are influenced because sedimentation makes metasequoia generate and tilt.It is lacking
When transplanting metasequoia on few surface soil or the insufficient topsoil of thickness, backfill soil should be carried out by related planting soil code requirement, make soil
Earth thickness reaches metasequoia master horizon thickness of earth covering, generally requires thickness in 0.9m or more.
In step s 5, metasequoia nursery stock takes the mode of stage excavation, avoids disposably cutting 1 periphery root system of metasequoia soil ball
It is disconnected.After the cutting of upper layer root system, the continuation of lower layer's root system can maintain metasequoia to grow.Lower layer is cut off again after upper layer cutting root system healing
Root system.Root system is orderly cut off, restores, reduce metasequoia because the system of taproot by destroying caused by the unbalance suddenly shadow of metasequoia moisture
It rings.It is fitly completely cured using fast knife saw, overlength lateral root, forms smooth face of being completely cured, protection is uniformly smeared at the face of being completely cured
Agent.
With reference to Fig. 1,1 diameter of metasequoia soil ball that metasequoia root carries after excavation is 8~10 times of the metasequoia diameter of a cross-section of a tree trunk 1.3 meters above the ground, metasequoia soil ball
1 with a thickness of 0.6~0.8 times of 1 diameter of metasequoia soil ball.General 1 diameter of metasequoia soil ball is no more than 1.8m, and otherwise metasequoia soil ball 1 is held
It is easy to crack to make root system by breakage, while metasequoia soil ball 1 is excessive also violates five sections, one environmental requirement.Act the metasequoia soil ball 1 dug out
It is covered with wet cloth and maintains 1 humidity of metasequoia soil ball, by the control of the soil moisture content of metasequoia soil ball 1 50%~60%, metasequoia soil ball 1
Soil grabs native balling-up, and that touches dissipates.It is the guarantee for promoting main root to restore, grow that soil ball, which keeps humidity, while being also to maintain metasequoia
The key survived.Metasequoia of marching into the arena answers soil ball complete, without loose, false soil ball phenomenon.
In step s 5, moisturizing cloth is wrapped up on metasequoia limb, the height of moisturizing cloth is from 1 surface of metasequoia soil ball to limb
At 3.5m~5m, metasequoia moisturizing cloth is using environmentally friendly cotton.
Suspension centre is protected with plank when metasequoia handling is transplanted and tree crown cannot mop floor, and soil ball is excessive should to wrap up soil ball handling to cultivation
Plant point.Metasequoia limb, greenery progress spraying and moisturizing are suitably given during metasequoia seedling transportation, and is simply covered, and are subtracted
Loss of water during few metasequoia seedling transportation.
It is that circle is drawn in the center of circle with metasequoia field planting point, circle range is when carrying out metasequoia field planting in step s 6 with reference to Fig. 1
Metasequoia plant pit (8) range.Along circle sideline, outside vertical is excavated downwards metasequoia plant pit (8), and metasequoia plant pit (8) diameter compares metasequoia
Big 0.6m~the 0.8m of 1 diameter of soil ball, metasequoia plant pit (8) depth is than 1 thickness depth 0.4m~0.5m of metasequoia soil ball.Excavate metasequoia plant pit
(8) when, straight crater wall is repaired when digging, makes plant pit upper edge and base vertical, while keeping crater wall smoothly straight.In metasequoia plant pit
(8) hole bottom is uniformly laid with 10kg peat soil, and peat soil layer upper berth sets the rubble drainage layer 3 of 0.2m thickness, and rubble drainage layer 3 uses grain
Diameter is that the scree of 40mm~60mm is set.The native mound 4 of element that heap sets with a thickness of 0.2m~0.3m in rubble drainage layer 3, really
Soil conservation ball bottom planting soil is closely knit.Wound protection measure is cleared up metasequoia root tree root and carried out again, and metasequoia soil ball 1 is placed
Metasequoia field planting is carried out on plain native mound 4.Soil ball is excessive should to wrap up soil ball handling to planting point, then wrap up suspension centre with clamping plate again
It is transplanted at station.30kg peat soil is sprinkled in soil to be backfilled, as backfill planting soil 5 after mixing uniformly, in metasequoia plant pit (8)
Interior artificial backfill planting soil 5 is simultaneously steady and sure, and after the completion of planting earthen backfill, 1 surface of metasequoia soil ball is higher than earth's surface 0.05m~0.1m.
It must manually be backfilled when the metasequoia plant backfill earthwork, so that soil ball the hollow phenomenon in periphery is occurred to prevent machinery backfill.
After metasequoia plant, soil ball water content will affect metasequoia and survive, and water content is too low to be not achieved metasequoia normal growth demand
Moisture when, metasequoia just will appear withered phenomenon, and water content is bigger to promote the poisoning of metasequoia root system to make metasequoia root system anaerobic respiration
Alcohol is generated bad root phenomenon occur root system is caused to send out rotten the phenomena of mortality occur.Therefore in step s 6, before carrying out plantation earthen backfill,
The pvc pipe 2 of both ends open is placed in 1 two sides of metasequoia soil ball, with reference to Fig. 1, the diameter of pvc pipe 2 is 75mm~80mm, pvc pipe 2
Tube head is embedded to 0.12m~0.16m depth, 2 nozzle of pvc pipe in rubble drainage layer 3 and carries out breathable tube sealing.For newly transplanting water
China fir heavy rain should in time be excluded the ponding in plant pit by pvc pipe 2 later, when long-time dry weather, pass through 2 Taoist temple of pvc pipe
1 humidity of metasequoia soil ball is examined, moisturizing plan is formulated.Pvc pipe 2 can also accelerate having for metasequoia fibrous root as metasequoia humidity is adjusted simultaneously
Oxygen breathing, promotes metasequoia root growth and development.After metasequoia transplants maturation, its own root system is torn open again when can satisfy water demand
Except pvc pipe 2 carries out backfill improvement planting soil.
Indwelling watering cave on planting soil 5 is backfilled, metasequoia plant terminates first piling and is fixed, and sends sole duty water conservancy project to metasequoia soil
1 periphery of ball carries out low hydraulic pressure irrigation, while sending a full-time greening personnel to pour water area to soil ball periphery and carrying out backfill fine earth, really
Without hollow phenomenon between soil conservation ball and soil, 1 fibrous root of metasequoia soil ball is never destroyed when backfilling fine earth, earthwork sedimentation is with water irrigation
Supplemented by owner's work.After metasequoia root water has poured, a small amount of repeatedly watering is followed for later period watering.
With reference to Fig. 2 and Fig. 3, the metasequoia just transplanted is due to center of gravity height, and tree crown is big, and after root water irrigates, soil starts to wrap
Root system in soil ball, metasequoia shake, and will cause root fibrous root and break main root cannot heal, and can seriously destroy root power of regeneration
Cause the metasequoia phenomena of mortality.Therefore metasequoia is fixed using triangular support, and metasequoia is fixed using bottom support leg when gusseted
Fixed point angle is as far as possible close to 120 degree, to guarantee metasequoia support triangle stability.It is beaten by metasequoia plant pit (8) after backfill
Spud pile 6, the diameter 80mm or more of spud pile 6, spud pile 6 should be embedded to underground 0.6m or more.Three spud piles 6 are in 120 ° of exhibitions
It opens, support rod 7 is set up on spud pile 6, gusseted is carried out to metasequoia plant.The length of support rod 7 is 4m, under support rod 7
Foot sectional area 80mm2, upper foot sectional area 50mm2, and at least 0.15m in the leftover bits and pieces embedment original soil of support rod 7.Spud pile 6 with
Between support rod 7, iron wire binding and fixing are used between support rod 7 and support rod 7, are wound with straw rope on trunk 11 in order to avoid support rod
7 direct friction trunks 11, cause bark to wear.
Since metasequoia limb is tall and big tall and straight, after metasequoia has poured root water, was unclamped at second day and is fixed temporarily fir pile previously,
Are retightened by fir pile and is subject to foot stake and is fixed for metasequoia root backfill fine earth and then metasequoia righting.
Native balling-up should be grabbed with metasequoia soil ball 1 for the metasequoia newly transplanted, slightly band moisture is preferred in hand.Plant initial stage should pour
Preceding water three times, metasequoia start fast-growth after 5.6 months, and development requires large quantity of moisture and sent out from limb foliation to root system
It educates.Nursery stock larger for metasequoia specification was irrigated 1 time in 4.5.6.7 month using one week, respectively used high pressure using the morning and evening in 5.6 months
Rifle carries out moisturizing to branches and leaves trunk 11, slows down the evaporation of blade face moisture.Metasequoia soil ball 1, without ponding state, guarantees in this way in wet
Moisture normally for foot, can also promote root system to develop, and accelerate system of fibrous root aerobic respiration.Focus on metasequoia during the maintenance of metasequoia moisture
Dry telomic leaves situation, it is ensured that metasequoia trunk is without bald fallen leaves phenomenon.After metasequoia root system development is complete, it can satisfy at the top of limb
The supply of itself moisture, can stop moisturizing at the top of limb, be changed to regular root irrigation.It is also answered later for newly transplanting metasequoia heavy rain
The ponding in plant pit is excluded in time, the ponding time is caused greatly too long with waterproof, so that metasequoia root system anaerobic respiration is generated alcohol and goes out
Existing bad root phenomenon.
Manual cleaning afforests the building waste in place, and miscellaneous filling plant etc. influences the rubbish of landscape effect and trees surviving rate
It carries out entrucking and has bad luck to designated place.Classification accumulation is carried out to metasequoia plant tool, stub, iron wire and is cleared up in time.To water
The earthwork of China fir cofferdam, which arrange, removes the extra earthwork, and clean to live branches and leaves ensures that construction area meets environmental protection inspection and acceptance standard
The current obstacle in cleaning scene.
Metasequoia pipe supports standard: growth is vigorous, with luxuriant foliage and spreading branches in leafy profusion, handsome in appearance, the unbiased bald phenomenon of hat, the straight height of trunk 11
It is unified, no disease and pests harm deadwood dead leaf phenomenon.
In the step s 7, tree body aerial part (especially blade face) the easy dehydration because of transpiration, it is necessary to which water spray is protected in time
It is wet.Spraying water, it is thin and uniform to require, and spray and on the ground each position and surrounding space provide wet microclimate environment for tree body, can
It is spraying using giant.Metasequoia need to increase water spray moisturizing dynamics after foliation of branching out.
In the step s 7, newly plant metasequoia pours root water for the first time and wants saturating.The watering cave that metasequoia leaves when planting, first
It is secondary sprinkle profoundly water after should fill and lead up or slightly above surrounding ground ensures that perception effect is good, for PVC drain pipe nozzle carry out tube sealing with
Ponding when anti-rainy or watering, but 2 air circulation of pvc pipe cannot be influenced.In time to water in 2 material of pvc pipe after continuous rainstorm
Situation is checked that discovery ponding is cleared up in time, it is ensured that root system air can normally circulate.
In the step s 7, initial stage is transplanted in metasequoia, the bud sprouted to metasequoia will be protected, allow its foliation of branching out, to
