Technical Field

The utility model belongs to the technical field of the technique of afforestation and land desertification are administered and specifically relates to a porous cellucotton retaining structure is related to.

Background

At present, soil is mostly greened in cities and suburbs, and the environment can be directly improved after greening. In the actual greening process, the vegetation is generally directly transplanted to the position needing greening.

Chinese patent No. CN101773037B discloses a method for greening a plant net, which comprises the steps of 1) leveling waste land; 2) paving a clay layer; 3) preparing and paving a greening substrate; 4) spraying water to saturate and settling; 5) laying and fixing a plant growth net; 6) covering a protective layer; 7) and (5) carrying out water content management. The utility model discloses the method is not only material resource abundant, and is with reasonable costs, and construction process is simple, can fully ensure the plant moreover to sprout in earlier stage and later stage growth, reaches effective afforestation effect, can gradually improve soil structure, resumes ecological environment, reaches the purpose of reduction natural environment. The method is mainly used for greening and governing engineering of waste lands.

The above prior art solutions have the following drawbacks: because the unreasonable development and utilization of land and the continuous aggravation of pollution, the abandoned idle land with a large area appears, and the soil has poor texture, the underlying surface contains more stones, the water storage capacity is small, the physical structure is unreasonable, and the plant growth is not facilitated.

Chinese patent CN101538622A discloses a method for recovering vegetation in situ in waste land, which adopts the technical scheme that: the grass seeds and the growth substrate are uniformly mixed according to the weight ratio of 1: 10 to prepare the seeding material, the seeding material is uniformly covered on the surface of the waste land, and then the cultivation management is carried out according to the conventional method.

The method belongs to the traditional soil replacement and filling type, and has the defect that water in soil can continuously seep downwards, so that the water content in the soil is continuously reduced, and the growth of plants is influenced.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art existence, one of the purposes of the utility model is to provide a porous cellucotton retaining structure, through pre-buried porous cellucotton in soil, carry out quick absorption storage and slow release to the water in the soil, the plant sustainable absorption of being convenient for.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: a porous fiber cotton water storage structure is shown in figures 1 and 2 and comprises a foundation soil layer 1, a water storage layer 2 is arranged on the upper side of the foundation soil layer 1, and the water storage layer 2 is formed by arranging a plurality of porous fiber cotton 21.

A planting soil layer 3 is arranged on the upper side of the water storage layer 2, and the water storage layer 2 is arranged between the foundation soil layer 1 and the planting soil layer 3. Plants are planted on the planting soil layer 3. The underside of the foundation soil layer 1 is in contact with the groundwater layer.

When the vegetation is watered in overcast and rainy days, moisture falls on planting soil layer 3, oozes along planting soil layer 3, when permeating in aquifer 2, porous cellucotton 21 absorbs moisture with the mode that the sponge absorbs water, lets rich water in the porous cellucotton 21. During the growth process of the plants, the roots of the plants can continuously absorb water from the planting soil layer 3. The water content of the soil gradually decreases as it permeates, evaporates and is taken up by the plants. At this time, the water in the porous cellucotton 21 is slowly released and supplemented to the planting soil layer 3 for the growth of plants. Compared with a planting structure without a water storage layer, the porous cellucotton plays a role in fast storage and slow release of water, and the root system of the plant can be in the environment with high water content for a longer time, so that the greening effect is improved, and the survival rate of the plant is increased.

In order to prevent that the mixed silt of water from infiltrating into the water-storage layer 2 from planting the soil layer 3 gets into porous cellucotton 21, block up porous cellucotton 21, influence porous cellucotton 21's effect of absorbing water, arranged one deck interfacial layer 4 between water-storage layer 2 and planting soil layer 3, interfacial layer 4 is arranged by geotechnological cloth 41, blocks up silt, and lets hydroenergy enough infiltrate into water-storage layer 2.

In a specific soil layer, the basic soil layer 1 contains a certain amount of saline-alkali components, and the growth of plants is influenced. In order to carry out the separation to saline and alkaline composition, arrange barrier layer 5 between aquifer 2 and basic soil layer 1, barrier layer 5 is arranged by a plurality of drain bars 51, and barrier layer 5 directly blocks saline and alkaline composition.

Have arranged many row salt pipes 6 at drain bar 51's downside, arrange the level of row salt pipe 6 and arrange, follow saline and alkaline composition and follow the same infiltration that upwards of groundwater, after saline and alkaline composition and drain bar 51 contact, can receive stopping of drain bar 51, make saline and alkaline composition pile up the gathering in drain bar 51 department, later along with the increase of saline and alkaline composition, moisture and saline and alkaline composition can be towards arranging salt pipe 6 department infiltration, get into row salt pipe 6, finally flow along arranging salt pipe 6 and arrange away, make the gathering can arrange away via row salt pipe 6 at drain bar 51 saline and alkaline composition, thereby reduce saline and alkaline composition's erosion to drain bar 51.

When planting herbaceous plant, porous cellucotton 21 tiling is in the downside of planting soil layer 3, will be adjacent one when laying, and the contact can not have the gap between cotton and the cotton, avoids influencing the effect of absorbing water, so be provided with 45 cutting contact limit on porous cellucotton 21, the handing-over is laid together, avoids moisture loss.

Example 2: the embodiment of the water storage structure of the porous cellucotton is different from the embodiment 1 in that when shrub plants are planted, the porous cellucotton 21 is laid on two sides of the plants, and the root systems of the shrub plants are developed compared with those of herbaceous plants, so that the porous cellucotton 21 cannot be laid under the root systems, and needs to be laid on two sides for water-containing moisture supplement, and further the porous cellucotton 21 is prevented from influencing the growth of the root systems. Wherein, the geotextile 41 wraps the porous cellucotton.

Example 3: a porous fiber cotton water storage structure is different from embodiment 2 in that when arbor plants are planted, porous fiber cotton 21 is paved around the plants, and the porous fiber cotton 21 cannot be paved on two sides of the root system and at four corners to supplement moisture due to the fact that the root system of the arbor plants is more developed than that of shrub plants, as shown in figure 4. Wherein, the porous cellucotton 21 is vertically laid to avoid the blockage of the cavity.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
