Abstract

Platanus orientalis tree is one typical arbor and street tree, and normally, its tree top is cut off to develop side branches, resulting in waste and trouble in disposing. The present invention provides one kind of large branch suspending and layering method for plane tree as street tree to culture the large branch into tree. The method can save the seedling growing time of 5-8 years, change waste into useful seedling, protect environment and result in great economic utility.

Description

Large branch suspending and layering averruncation method for plane tree as street tree

One, technical field

The present invention relates to a kind of branch pruning method, particularly relate to a kind of huge branch pruning method at oriental plane tree.

Two, background technology

Oriental plane tree is a kind of typical high megaphanerophyte type street tree.Because the tall and big limb in tree crown centre often interferes with the cable of road both sides, simultaneously also for the top that suppresses trunk slightly, the development side shoot so the huge limb work in oriental plane tree centre is drastically pruned, becomes people's general knowledge already.Problem is that the huge branch of pruning all is to do garbage disposal, and this is not only a kind of wasting of resources, and the characteristics of this branch class rubbish are that volume is big and in light weight, it is very inconvenient to load and transport, not only the cost of transportation height deals with also trouble, and burning can contaminated air, piles, buries and account for the place especially.

For the air layering of branch, should be general knowledge well known to those skilled in the art.But present known air layerage all is to carry out on the tiny branch that is confined to give birth to one or two years, and it only is at the seeds that are difficult for surviving with cuttage, can improve its survival rate with this method, and therefore, the air layering breeding all is to replenish as a kind of of cuttage.Why is air layering all to give birth on the tiny branch in one or two years to carry out usually? reason is that the operator will wrap a certain amount of earth at the band girdle place of branch, the humidity that keeps these earth in the 2～March that must grow up at the new root of branch simultaneously, for reaching this purpose, people normally pinch on branch with a sposh that sticks together duck's egg or goose egg size and wrap with film.For the huge branch of diameter at 8～20 centimetres, required earth more than 20kg, properly and easily wraps in many like this earth on the branch, and remains its suitable humidity at least during press strip, not by special method, is difficult to realize.

Three, summary of the invention

The objective of the invention is provides a kind of large branch suspending and layering averruncation method for plane tree as street tree to society, with the air layering of the huge branch of smooth realization oriental plane tree, eliminates a large amount of rubbish that cause because of pruning simultaneously to greatest extent.

The object of the present invention is achieved like this: during 5～June, for the huge branch of oriental plane tree to be pruned, earlier to make a width be 5～10 centimetres ringing in a selected position of being convenient to operate on limb, and thoroughly strike off the cambium on xylem surface with blade part, use the polypropylene woven bag that has plastic film to make lining of 35 * 90cm to load onto 20～40kg earth again, the humidity of earth can be agglomerating to clutch, can loosing of touching is degree, after tightening sack, be tied to the head of woven bag respectively with three ropes, tail and waist, then the other end of three ropes is walked around the crotch of band girdle mouth top, spur its end, make woven bag be hung on limb band girdle mouth place, woven bag is horizontal vacant state, fixedly the woven bag lower surface must exceed band girdle mouth lower edge 2cm behind the end, vertically cut long a 20～30cm long openning in woven bag waist center over against a side of band girdle mouth with cutter then, retract the woven bag and the film of openning both sides with hand, after spilling 2～3kg earth, encase this limb, bag interior earth is fully contacted with the bark of band girdle mouth upper edge, and make the both sides mouth of sack openning also overlapping along offside junction at trunk, with the 4th rope woven bag laterally is fastened onto on band girdle mouth upper edge and the above limb around band girdle mouth again, through 2～March, as fine as a spider's web fibrous root tightly is fixed on the earth in the bag on the limb in the woven bag, this moment can be sawed-off with limb from the band girdle mouth lower edge, put down gently in ground, remove its 1/3 tree crown, and promptly can be used as into the tree field planting after removing whole woven bags and film with scissors.

Owing to adopt technique scheme, can receive following remarkable result:

1, owing to the branch that is used for press strip is perennial huge branch, can directly do the street tree field planting after the intercepting, compare, can save the seedling raise period in 5～8 years with conventional air layering or cuttage and seedling culture.

2, under the situation of identical trunk diameter, oriental plane tree through growing seedlings and grow up to for many years, the main distributed areas of its fibrous root have been transferred to and the corresponding to annular region of crown diameter, when taking transplanting, can not allow root with soil block greatly to the size identical with tree crown, therefore must lose most fibrous roots.And the oriental plane tree that this law obtains, its fibrous root accounts for more than 90% of root total amount, and preserves from.Therefore not only survival rate was up to 100% after the latter planted, and growth rate that the more important thing is the latter after surviving is also far above the former.

3, the huge branch of the oriental plane tree under repairing according to a conventional method is the rubbish that is difficult to dispose, and the present invention becomes it into the Cheng Shu that can directly do the street tree field planting, has not only reduced rubbish and disposal cost, has protected green resource again, also can produce huge economic benefit.

Claims

1, a kind of large branch suspending and layering averruncation method for plane tree as street tree, comprise band girdle to huge branch, remove cambium, Pig and opening, wrapping, saw cuts, repair tree crown, go bag and 8 steps of field planting, it is characterized in that: during 5～June, for the huge branch of oriental plane tree to be pruned, earlier to make a width be 5～10 centimetres ringing in a selected position of being convenient to operate on limb, and thoroughly strike off the cambium on xylem surface with blade part, use the polypropylene woven bag that has plastic film to make lining of 35 * 90cm to load onto 20～40kg earth again, the humidity of earth can be agglomerating to clutch, can loosing of touching is degree, after tightening sack, be tied to the head of woven bag respectively with three ropes, tail and waist, then the other end of three ropes is walked around the crotch of band girdle mouth top, spur its end, make woven bag be hung on limb band girdle mouth place, woven bag is horizontal vacant state, fixedly the woven bag lower surface must exceed band girdle mouth lower edge 2cm behind the end, vertically cut long a 20～30cm long openning in woven bag waist center over against a side of band girdle mouth with cutter then, retract the woven bag and the film of openning both sides with hand, after spilling 2～3kg earth, encase this limb, bag interior earth is fully contacted with the bark of band girdle mouth upper edge, and make the both sides mouth of sack openning also overlapping along offside junction at trunk, with the 4th rope woven bag laterally is fastened onto on band girdle mouth upper edge and the above limb around band girdle mouth again, through 2～March, from the band girdle mouth lower edge that limb is sawed-off, put down gently in ground, remove its 1/3 tree crown, and promptly can be used as into the tree field planting after removing whole woven bags and film with scissors.
