The utility model discloses a sandy soil farmland, at the in-process of precipitation and irrigation, during moisture sees through geotechnological cloth and enters into the porous disk and flow through the porous disk, can effectively avoid moisture too much ground to be detained in the bottom on sandy soil planting layer, because plant roots breathes the emergence of the not smooth "seedling burning" phenomenon that leads to when having avoided current sandy soil farmland only to set up the water proof geomembrane.

Description

Sandy soil farmland with bottom drainage function

Technical Field

The utility model relates to a sandy soil farmland, more specifically the theory that says so especially relates to a sandy soil farmland with bottom drainage function.

Background

In the northwest region of China, xinjiang, tibet, inner Mongolia, qinghai and other lands have a large amount of sandy lands, and as the sandy lands cannot be used for planting crops, a large area of sandy lands are wasted. One of the main reasons that sandy soil cannot be used for crop planting is that the water-retaining property of sandy soil is poor, and after rainfall or irrigation water is poured onto the sandy soil, the water can seep down quickly, so that the water cannot be retained at the position where the plant root system can reach.

In order to avoid the problem that the existing sandy soil can not store water for a long time, a waterproof geomembrane is laid at the bottom of the sandy soil so as to prevent the water from seeping downwards. Laying waterproof geomembrane although solved the problem of infiltration of moisture, nevertheless because waterproof geomembrane is waterproof, can lead to irrigation water or precipitation to be detained in the top of geomembrane, the bottom root system of plant is in the sand soil that the water content is too big for a long time like this, and the great sand soil oxygen content of water content is minimum for plant roots's respiration is inhibited, causes the emergence of "burning seedlings" phenomenon to appear in the plant.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1 and fig. 2, the utility model discloses a main view and the top view in sandy soil farmland with bottom drainage function, local area's enlargements in fig. 1 have been given in fig. 3, shown sandy soil farmland comprises sandy soil foundation 1, side retaining wall 2, water proof geomembrane 3, porous disk 4, geotechnological cloth 5 and sandy soil planting layer 6, shown sandy soil farmland is built on sandy soil foundation 1, 2 intervals of both sides retaining wall and mutual parallel arrangement, the sandy soil farmland region for the structure between the retaining wall 2 of both sides. The water-resisting geomembrane 3 is laid on the sandy soil foundation 1 between the retaining walls 2 on the two sides and on the inner walls of the retaining walls 2 on the two sides so as to avoid the infiltration of moisture and solve the problem that the sandy soil foundation 1 is not easy to retain moisture.

One deck porous disk 4 has been laid to the top of water proof geomembrane 3 shown, and one deck geotechnological cloth 5 is laid to the top of porous disk 4, and the top of geotechnological cloth 5 is sandy soil planting layer 6, and sandy soil planting layer 6 comprises sandy soil, and both sides barricade 2 realizes the effect of blockking the sandy soil planting layer 6 both sides, and crops are planted in sandy soil planting layer 6. Because set up geotechnological cloth 5 between sandy soil planting layer 6 and porous disk 4, when having guaranteed that the moisture in sandy soil planting layer 6 can infiltrate down in the porous disk 4 like this, also keep apart sandy soil and crops 7's root system, can effectively avoid sandy soil and crops root system to enter into on the porous disk 4.

Like this, in precipitation and irrigation process, the moisture that flows into in sandy soil plants layer 6 can see through geotechnological cloth 5 and permeate into porous disk 4, and flow porous disk 4, just so avoided the too much delay of moisture in sandy soil plants the bottom of layer 6, make the bottom of sandy soil plants layer 6 contain sufficient oxygen, solved current water proof geomembrane 3 time because the crops root system that the bottom moisture of sandy soil plants layer 6 leads to is too much when only adopting, just also avoided crops 7 the phenomenon of "burning seedlings" to appear.

A water storage tank 9 is dug on the sandy soil foundation 1 outside one end of the side retaining wall 2, the water storage tank 9 is communicated with the water permeable plate 4, and water extending into the water permeable plate 4 flows into the water storage tank 9 and is stored. The water stored in the water storage tank 9 can be used for irrigation. In order to ensure that the sandy soil thickness in the sandy soil planting layer 6 meets the planting requirement, the rear end of the sandy soil planting layer 6 is between 30cm and 60cm.

The side retaining wall 2 is shown for blocking the sandy soil and water in the sandy soil planting layer 6 from overflowing, so the side retaining wall 2 has a certain bearing capacity, and the side retaining wall 2 is ensured to be low in cost and convenient to build as far as possible, so the side retaining wall 2 adopts the structural form shown in fig. 4. The side retaining wall 2 is composed of ground piles 10, iron wire nets 11 and binding belts 12, a plurality of ground piles 10 are driven into the sandy soil foundation 1 at even intervals, the iron wire net 11 is arranged between every two adjacent ground piles 10, and two ends of the iron wire net 11 are bound on the ground piles 10 through the binding belts 12, so that the side retaining wall 2 with lateral stress capacity is formed, and meanwhile, the side retaining wall is low in manufacturing cost and simple in construction.

As shown in fig. 5, a schematic structural view of the permeable plate 4 of the present invention is given, the permeable plate 4 is composed of a plate body 13, the plate body 13 is rectangular, vertical permeable holes 14 are uniformly formed on the plate body 13, and a horizontal water flow hole 15 is formed at the bottom of the plate body 13 along the length direction thereof; the upper end opening of the vertical permeable hole 14 is communicated with the outside, the lower end opening is communicated with the horizontal water flowing hole 15, and both ends of the horizontal water flowing hole 15 are communicated with the outside. Therefore, after moisture in the sandy soil planting layer 6 enters the upper part of the water permeable plate 4 through the geotextile 5, the moisture firstly flows into the transverse water flowing holes 15 through the vertical water permeable holes 14, and then the moisture flows in the transverse water flowing holes 15 in the adjacent water permeable plate 4 until the moisture flows into the water storage tank 9.
