Abstract

The invention provides a salt-removing pipe containing a high-strength water-permeable layer. The salt-removing pipe comprises a concealed pipe and the water-permeable layer, wherein the external surface of the concealed pipe is wound with a nylon mesh. The invention further provides an application of the salt-removing pipe containing the high-strength water-permeable layer in salt removing of saline-alkaline land. According to the salt-removing pipe and the application thereof, the concealed pipe is high in flexural strength, large in flexural modulus and high in Vicat softening point, wherein the flexural strength is 52MPa to 61MPa, the flexural modulus is 50MPa to 59MPa, and the Vicat softening point is 160 DEG C to 170 DEG C; the growth speed of plants planted in the saline-alkaline land which is subjected to salt-removing amendment by using the salt-removing pipe provided by the invention is increased greatly; the plants planted in the saline-alkaline land which is subjected to salt-removing amendment by using the salt-removing pipe provided by the invention are high in survival rate and high in disease resistance; and taking cedar for example, the survival rate of transplanted cedars can reach 95.8% to 99.0%, and the disease resistance to common diseases of the cedars is high.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a salt discharge pipe with a high-strength water-permeable layer and its application in saline-alkali land salt discharge. Background technique [0002] With the continuous development of social economy, urban land resources are increasingly scarce, and coastal cities have turned their attention to land reclamation. Reclaiming land from the sea can solve the land shortage problem to varying degrees. But on the other hand, we must see that land reclamation has also directly or indirectly led to the degradation of the ecosystem in coastal areas, destroying the natural attributes of tidal wetlands and the unique natural landscape of coastal tidal flats; The constraints of climate and other ecological factors are mainly reflected in the high groundwater level and the salinity of groundwater is greater than 30g / L, which is equivalent to the salinity...
