Abstract

A water-draining and air-permeating device for big tree transplantation is characterized in that: the water-draining and air-permeating device mainly comprises a water-draining and air-permeating pipe, the lower end of the water-draining and air-permeating pipe is provided with a lower cover, and a plurality of small water-draining and air-permeating holes are evenly distributed on the periphery of the sidewall of the lower part of the water-draining and air-permeating pipe. The water-draining and air-permeating device has the advantages that: since coastal saline-alkali regions have a high ground water level, a high salt content, a heavy texture, a poor structure, a small porosity and a small permeability coefficient, the survival rate of big transplanted nursery stocks is low, the conventional blind pipe technique is not suitable for trees in a small area and a single tree, and the adoption of the technique can effectively solve the problem in small-area greening, decrease the ground water level and increase the oxygen content of roots and the survival rate of nursery stocks.

Description

Big tree transplanting draining gas permeable devices
Technical field
The utility model belongs to stock growing, relates in particular to a kind of big tree transplanting draining gas permeable devices.
Background technology
Current landscape engineering often will be realized greening in the short period of time, beautify effect.Because large-tree-shaped height is big, the attitude grace is transplanted big tree and can be quickened the urban afforestation process, represent the plant landscaping effect rapidly.Therefore, big tree transplanting also just is applied in the afforestation more and more.Though big tree transplanting becomes scape fast, more conventional garden seedling tree survives difficulty, and reason mainly contains the following aspects: 1) set olderly greatly, phasic development is old, the regeneration capacity of cell a little less than, excavate and the process of planting in the root regeneration that damages slow, new root generating ability is poor.2) owing to reason young, that strengthen the eccentric growth of tree in age, the root system spreading range of trees very big (generally surpassing tree crown floor projection scope), and it is very dark to penetrate soil layer, effective absorption root is near deep layer and the tree crown projection, the soil ball is with and is absorbed root seldom when causing excavation to set greatly, and the many suberifications of root are serious, and casparian strip has stoped the absorption of moisture, and the absorption function of root system obviously descends.3) large-tree-shaped height is big, and the rising area of branches and leaves is big, for making it bring into play afforestation effect as early as possible and keeping its original graceful attitude, how not to carry out overweight lopping again; Root system is apart from the tree crown distance in addition, brings certain difficulty for the conveying of moisture, thus be difficult to behind the big tree transplanting set up as early as possible on the ground, underground water balance.4) trees are big, and native ball is heavy, easily causes impaired, the native ball fractured of bark, branch to fracture in digging, the process of carrying, plant, and survives thereby jeopardize big tree.
In addition, also exist soil alkaline content height on the ground at coastal saline-alkali, the subterranean water level height, quality is sticking heavy, reasons such as gas permeability difference.At coastal saline-alkali ground lowering of watertable, suppress aspects such as the soil accumulation of salt in the surface soil accumulation of salt in the surface soil, generally take to lay filter layer, blind pipe is installed, and measures such as big hydraulic pressure salt can effectively reduce the soil subterranean water level, suppress the soil accumulation of salt in the surface soil accumulation of salt in the surface soil, the advantage of plant growing is provided.Large tracts of land are afforested but the measures such as filter layer, installation blind pipe of laying relatively suit, and are less for area, and do not have the place of drainage system, and this method is restricted, and in addition, this measure does not have ventilative effect.Current also have relevant report about the nursery stock gas permeable devices, Wu Jianping, the firm utility model of Shen Zhi disclose a kind of permeability cell of transplant big tree, this device can effectively improve nursery stock root gas permeability, satisfy the root system of plant respiratory demand, but in arriving rainy season, do not have the effect of draining and lowering of watertable, root system of plant is breathed and is suppressed, and still can cause the mortality of nursery stock.
The utility model content
The utility model provides a kind of big tree transplanting draining gas permeable devices at the deficiencies in the prior art, can the draining lowering of watertable, can breathe freely again, satisfy the root system respiration demand, can effectively solve the subterranean water level height, the problem of root system of plant gas permeability difference can significantly improve big tree transplanting survival rate.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of big tree transplanting draining gas permeable devices, it is characterized in that: mainly constitute by the ventilative body of draining, the ventilative body bottom of described draining is provided with bottom, is evenly equipped with the ventilative aperture of some drainings around the ventilative body lower sides of draining.
The ventilative aperture place of the draining of the ventilative body of described draining is coated with gauze.
The ventilative body top of described draining is provided with loam cake.
Beneficial effect: coastal saline-alkali area subterranean water level height, salt content height, quality sticking heavy, structure is poor, porosity and osmotic coefficient are little, big nursery stock transplanting success is low, original blind pipe technology is not suitable for small size and individual plant is counted wood, adopt this technology can effectively solve a microcell greening difficult problem, lowering of watertable increases the root oxygen content, improves plant percent.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a scheme of installation of the present utility model.
Embodiment
Below in conjunction with preferred embodiment, details are as follows: a kind of big tree transplanting draining gas permeable devices to embodiment that foundation the utility model provides, mainly constitute by the ventilative body 1 of draining, the ventilative body bottom of described draining is provided with bottom 2, is evenly equipped with the ventilative aperture 3 of some drainings around the ventilative body lower sides of draining.The ventilative aperture place of the draining of the ventilative body of described draining is coated with gauze 4.The ventilative body top of described draining is provided with loam cake 5.A among Fig. 2: face of land line B: tree well C: filter layer.
Embodiment
One. the making of draining permeability cell
Choose pvc pipe or thick bamboo tube or the steel tile of diameter 15-20cm, seal the bottom, evenly punching according to bottom 20-40cm place, and aperture 0.5cm, punching place is wrapped up with gauze.The pipe range weak point is by planting trees kind decision, guarantees the pipe 20cm that bassets.The mouth of pipe is added a cover.
Two. pipe laying
Deep-cut 20cm again in tree well one side, the draining permeability cell is inserted, lay filter layer thickness 15-20cm in the tree well, make the drainpipe punch position over against filter layer.Plant trees filling planting soil.The filter layer material is by two or more is formed in vermiculite, stone, rough sand, slag, the pine needle.
