CN1263371C - New root growing method for street yellow oak to be transplanted - Google Patents

Abstract

Street trees on both sides of roads need to be transplanted in an urban road extending and improving project. Because a traditional transplanting method needs to cut off all main roots and whole tree crowns, a plurality of street trees are dead in the transplantation, and the roots and the tree crowns can be restored after many years even though the transplanted trees are luckily survived. The present invention adopts a trunk band girdle and suspending bag wrapping method for aiming at the street trees of bigleaf fig trees to be transplanted, and a large number of novel roots of the street trees of bigleaf fig trees can be cultivated in short order. Thus, the present invention eliminates the death of the bigleaf fig trees because of transplantation and can also make the bigleaf fig trees rapidly restore the vigor after transplantation.

Description

Wait to move the street yellow oak new root pre-growing method

One, technical field

The present invention relates to the cultivation of yellow square rafter tree, particularly relate to a kind for the treatment of and move street yellow oak and carry out new root and cultivate in advance, thus the method that survives and recover rapidly tree vigo(u)r of guaranteeing to move street yellow oak.

Two, background technology

Because the construction and the development in city unavoidably will be extended and transform urban road, in these engineerings, usually need street tree migration with the road both sides.Yellow square rafter tree is one of modal street tree, be characterized in that tree crown is roomy, trunk is sturdy, growing way is healthy and vigorous, yet in order to transplant, during excavation, none is blocked its main root with escaping by luck, for the possibility of survival is arranged after it is transplanted, has to cut out whole tree crown again, after being unearthed, must send into the nursery gives treatment to, cultivate, rejuvenation, main root is all blocked during owing to excavation, only surplus collar portion minute quantity fibrous root, and trees absorption soil water branch and nutrition is the fibrous root that relies on more than 95%, the but transpiring moisture ceaselessly of sturdy trunk of back acrial part and huge fracture of planting will solve this to contradiction, needs high-caliber, meticulous culture technique.In fact, this transplanting is a big disaster to yellow square rafter tree, and survival rate generally is lower than 60%, the yellow square rafter tree that survives by sheer good luck, reaching the level of transplanting again needs 3～5 years, and recover original tree vigo(u)r then needs 6～8 years, and this management therebetween must drop into great amount of manpower and material resources.

Three, summary of the invention

The objective of the invention is at the huge injury of yellow square rafter usage tree root and tree crown in the migration and provide a kind for the treatment of to move yellow square rafter tree and carry out new root and educate method in advance to society, to realize transplanting whole the surviving of yellow square rafter tree, the operation and the cycle of save into nursery treatment, cultivating, and make the yellow square rafter tree after the transplanting can recover tree vigo(u)r rapidly.

The object of the present invention is achieved like this: when in a single day Bureau of Urban Planning determines and will the yellow square rafter tree in certain highway section be moved, then treating the new root of yellow square rafter tree implementation that moves in advance 2～March by gardens department educates in advance, its concrete operations are as follows: set trunk in the altitude range of ground 90～120cm at yellow square rafter, yellow square rafter tree trunk bark is carried out band girdle, the band girdle width is got 10～15cm, thoroughly strike off the cambium on xylem surface behind the band girdle with sharp weapon, use 40cm * 120cm specification then, pack into the earth of bag capacity 6/10～8/10 of the polypropylene woven bag that inside is lined with polyethylene film, when trunk diameter takes off limit during less than 30cm, surpass then capping of 30cm, the humidity of earth can be agglomerating to clutch, can loosing of touching is degree, after tightening sack, be tied to the head and the tail and the waist of sack respectively with three ropes, lift sack, after allowing the other end of rope walk around top limb, be controlled in respectively in three staff, adjust the position of sack, make it be in the accumbency vacant state, the lower surface of sack is higher than band girdle mouth lower edge 2～3cm, three fag ends then are fixed on the trunk, standardized the I-shaped openning of a side that then faces toward trunk in sack waist center, on, the length of following twice openning is consistent with the girth of band girdle mouth place trunk, long 20～the 25cm of vertical openning, retract two bag sheets about I-shaped openning, after allowing the interior earth of bag miss 3～5kg, crooked sack makes it be surrounded on band girdle mouth, allows bag interior earth fully contact with the band girdle mouth upper edge, laterally sack is anchored on the trunk with the 4th rope again.Through having overgrowed with new root in the bag after two months, this moment can be sawed-off with trunk from the band girdle mouth lower edge, removing 1/2 tree crown and all can direct field planting behind sacks and the film, if the time allows, can educate root time lengthening to 3 month with hanging bag.

After adopting such scheme, can receive following remarkable result:

1, owing to defeated passage under the nutrition of yellow square rafter tree trunk is completely severed, and under the stimulation of a large amount of nutrition moistening earth in bag that the huge tree crown in top is made except that the tree crown autophage, all the other all are used for the growth of new root, through observing, handle about back ten days by this programme, near the band girdle mouth upper edge, promptly bear a large amount of new roots, the bimester after, the new root in the bag is as fine as a spider's web.Yellow square rafter is set original root system will be depleted gradually under the situation of the following defeated nutrition that can not get tree crown, up to final death, through observing, this process reaches 7～8 months, therefore, set former root system at yellow square rafter and occur as yet when significantly depleted, new root and original old root in the bag are finished succession of the old by the new already.On this problem, often there are the mistaken ideas on the understanding in those skilled in the art, promptly think and break off defeated passage under the nutrition on the trees trunk fully, tree root can be final dead, nature can cause the death of whole strain tree, thereby hesitate to implement the trunk band girdle, but they do not know that but different types of trees are after to its trunk band girdle, there is huge difference the phase of keeping of its root system vitality, therefore, understanding fully this after date of keeping of different seeds, can find the technical program applicable to considerable seeds, and yellow square rafter is set this just one of the longest seeds of phase of keeping.As mentioned above, this programme can make to be waited to move yellow square rafter tree and bears a large amount of new roots in a short time, then must 3～5 years by traditional way, thereby not only can shorten the field planting time greatly, also save the management work of the treatment that moves in the nursery, cultivation, rejuvenation.

2, this programme has not only thoroughly been eliminated and has been moved the dead possibility of yellow square rafter tree, also can make it recover original tree vigo(u)r fully in two years.

This programme reduce more than 80% when 3, can make yellow square rafter tree transplant preceding preparation, by traditional way, when taking, must around tree root, dig a hollow place, also to cut off whole main roots successively, this is an extremely time-consuming thing of requiring great effort, and particularly will cut off the main root in centre, and is very difficult especially, therefore finish this work and generally all want more than half a day, only need to take sawed-off getting final product of time a few minutes in the band girdle mouth lower edge with saw and will move yellow square rafter tree by this programme.In addition, conventional method must be removed whole tree crown before transplanting, and a large amount of branches that these cut down have just become very unmanageable rubbish, and this programme then can significantly reduce this rubbish.
