Description

Technical Field

[0001] The utility model belongs to the technical field of flower beds, and particularly relates to a flower bed for reducing soil salt content. Background Art

[0002] The landscape nodes in the garden have the characteristics of prominent location, small area, high cost, etc. The greening and beautification of the nodes are the top priorities in garden greening, playing a crucial role in enhancing the overall landscape greening effect. In the current greening practice of landscape nodes in saline-alkali areas, there are many difficulties. For example, the greening area is small, and the surrounding areas are mostly hardened sites such as roads or squares, separated from large greening areas, forming a relatively closed soil environment. During the maintenance process, it is difficult for soil salts to be drained away with watering or precipitation. Coupled with the use of snow melting agents in the garden maintenance process, salts gradually accumulate in the greening soil, resulting in low survival rate of seedlings and poor growth, thus seriously affecting the landscape effect of node greening.

[0003] The application of modern saline-alkali land garden greening technology has solved the above problems of node greening to a certain extent. The specific technical measures are as follows: 1. Improve the site conditions, such as raising the ground, making an alkali drainage layer, digging a drainage ditch to lower the water level, replacing the soil, irrigating water to suppress alkali, etc. 2. Select salt-tolerant greening seedlings, such as Chinese ash, white elm, seabuckthorn, chinaberry, tree of heaven, sumac, paper mulberry, Russian olive, Chinese wolfberry, locust tree, mulberry tree, Amorpha fruticosa, tamarisk, etc. 3. Strengthen the maintenance management, drain water in time after watering or precipitation, lay turf or cover the surface soil to block the capillary action of the soil, reduce the evaporation of soil moisture, and slow down the soil alkalization. 4. Other advanced technologies, such as the application of water retaining agents and soil conditioners. These greening technologies have improved the survival rate of seedlings to a certain extent. However, overall, the measures are relatively complex, the implementation cost is high, and it is difficult to continuously reduce the soil salt content. Seedlings with high ornamental value but not salt-tolerant often show poor growth and it is difficult to form a good ornamental effect. Content of the Utility Model

There is a solar panel installation groove at the top of the condensate cover, and a solar panel for supplying power to the pumping device is installed; a water tank connected to the pumping device is provided inside the condensate cover; a water collecting trough is provided between the water tank and the condensate cover, and a recovery pipe is opened in the masonry flower bed at the bottom of the water collecting trough.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] Please refer to Figures 1-3 , the present utility model proposes a flower bed that can reduce the soil salt content, including a masonry flower bed 6, a desalination device, a saline water evaporation and recovery device, and a pumping device.

[0025] The masonry flower bed 6 is a traditional flower bed structure, made of ordinary bricks and jointed with cement mortar, and the surface is treated according to the landscape design requirements. The masonry flower bed 6 provides a supporting surface for the above-mentioned saline water evaporation and recovery device; in addition, the masonry flower bed 6 is generally a flower bed with regular shapes such as circular and square. For irregular-shaped flower beds, it is difficult to process the tempered glass modules.

[0026] The saline-alkali drainage device includes a saline-alkali drainage layer 3, a saline-alkali drainage pipe 2, and a sump 5; the saline-alkali drainage layer 3 is installed in the saline-alkali soil 14 directly below the masonry flower bed 6, and the saline-alkali drainage pipe 2 is provided inside the saline-alkali drainage layer 3; the middle position of the saline-alkali drainage pipe 2 is connected to the sump 5, and the water in the saline-alkali drainage pipe 2 can flow into the sump 5, and the lowest point of the sump 5 is lower than the bottom of the saline-alkali drainage pipe 2. Among them, the saline-alkali drainage layer 3 consists of stones with a thickness of 30 cm and a particle size of 0.5 - 1 cm and two layers of geotextiles 17 up and down. The function of the stones is to prevent the salt in the underlying saline-alkali soil from infiltrating back into the planting soil layer 13, and the function of the geotextiles 17 is to prevent sediment from infiltrating into the gravel layer and blocking the gaps on the saline-alkali drainage pipe 2.

[0027] The saline-alkali water evaporation and recovery device is installed at the top of the side wall of the masonry flower bed 6 and includes a condensate cover 10. There is a solar panel installation groove 11 at the top of the condensate cover 10, and a solar panel 12 that powers the pumping device is installed; there is a water tank 9 connected to the pumping device inside the condensate cover 10; there is a water collection trough 16 between the water tank 9 and the condensate cover 10, and a recovery pipe 7 is opened in the masonry flower bed 6 at the bottom of the water collection trough 16. The saline-alkali water collected in the water tank 9 evaporates under strong sunlight, and the water vapor condenses into water droplets when it encounters the upper condensate cover 10 and flows into the recovery pipe 7, and finally the desalinated water flows back into the planting soil 13 for reuse. The solar panels 12 should be installed at intervals in the battery panel installation groove according to the actual position of the flower bed and the change of the sun's azimuth during the day, which can not only ensure the normal power consumption of the water pump 1 and the water level sensor 15, but also have sufficient sunlight irradiating the water tank 9 and the bottom waterproof coiled material 8 to ensure the water evaporation effect. The top of the water tank 9 with and without the installed solar panels 12 is capped with a condensate cover 10 made of tempered glass and waterproofed. The water tank 9 and the condensate cover 10 should be customized into modules of the same size according to the size and shape of the masonry flower bed 6, and then spliced and pasted into a watertight whole, and a detachable module for cleaning the impurities in the water tank 9 is left.

[0028] The pumping device includes a water suction pipe 4, which is used to pump the saline-alkali water in the sump 5 into the water tank 9 for evaporation and recovery. A micro water pump 1 and a water level sensor 15 are installed at the bottom of the water suction pipe 4. The saline-alkali water is pumped into the water tank 9 by the water pump 1, and at the same time, the water level in the sump 5 is detected by the water level sensor 15 to prevent excessive water accumulation from affecting the saline-alkali drainage efficiency.

[0029] The working principle of the utility model: First, due to daily watering or natural precipitation, the salts originally in the saline-alkali soil 14 and those melted and infiltrated by deicing agents and the like flow into the saline-alkali drainage device with the water flow. Through the leaching and filtration of the saline-alkali drainage layer 3, they are finally collected in the sump 5 through the saline-alkali drainage pipe 2.

[0030] Secondly, the solar panels 12 arranged at intervals in the solar panel installation groove 11 supply power to the micro water pump 1 and the water level sensor 15, and pump the saline-alkali water collected in the sump 5 into the water tank 9.

[0031] Finally, the saline-alkali water collected in the water tank 9 evaporates under sunlight irradiation. The water vapor condenses into water droplets when it encounters the condensation cover 10 made of toughened glass, and finally flows into the upper layer of planting soil 13 in the flower bed through the condensate recovery pipe 7 embedded in the masonry flower bed 6. The salts in the saline-alkali water remain in the water tank, and the water tank is cleaned regularly manually.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
