Technical Field

[0001] The utility model relates to the technical field of land improvement, in particular to a salt-isolating, salt-draining and greening device for saline-alkali land. Background Art

[0002] Salt-alkali land is a type of land that is widely distributed around the world, especially in arid and semi-arid areas. These areas usually face problems such as excessive soil salinity, water shortage and fragile ecological environment. The existence of salt-alkali land seriously limits the agricultural utilization value and ecological function of the land.

[0003] Most of the existing methods for improving saline-alkali land are to lay a sand and gravel filter layer on the saline-alkali land, and an improved soil layer for planting plants is laid on the upper part of the sand and gravel filter layer. A number of salt drainage pipes are provided in the saline-alkali land below the sand and gravel filter layer. The salt and alkali in the saline-alkali soil are discharged through the salt drainage pipes, thereby reducing the salt and alkali content in the saline-alkali soil and improving the saline-alkali soil.

[0004] However, this type of land improvement device relies more on rainwater or artificial irrigation to dilute the salt in the soil, and is not suitable for arid areas with less rain. In addition, large-scale artificial irrigation wastes water resources, is difficult and cumbersome to operate, and is labor-intensive.

[0005] Therefore, the prior art needs to be further developed. Utility Model Content
