Problems solved by technology

[0003] Rational development and utilization of saline-alkali land resources has become a thorny issue at present. Salt discharge pipe salt discharge technology can be used to improve saline-alkali land. However, the existing salt discharge pipe salt discharge technology is still not particularly ideal, for example:
[0004] (1) The existing dark pipe body has low bending strength, small bending modulus, and low Vicat softening point;
[0005] (2) After using the existing salt discharge pipe to discharge salt, the saline-alkali soil 0-30cm contains high saline-alkali content, which is not conducive to plant growth;
[0006] (3) After improving the saline-alkali land with the existing salt discharge pipe, the plant survival rate is low and the plant growth rate is slow
[0007] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention provides a salt discharge pipe with a water-permeable layer, which includes a hidden pipe and a water-permeable layer. The permeable layer includes a lower permeable layer and an upper permeable layer, and the lower permeable layer is laid sequentially from bottom to top: non-woven fabric layer, red jade soil layer, first mixed stone layer; the upper permeable layer is sequentially laid from bottom to top Laying: the second mixed stone layer, leaf humus layer. The invention also provides the application of the salt discharge pipe with a water-permeable layer in salt discharge in saline-alkali land. The hidden pipe of the present invention has good flexural strength, flexural modulus, and Vicat softening point; after using the salt discharge pipe of the present invention to discharge salt for one year, the pH in the 0-30cm soil of saline-alkali land is 7.0-7.5; After the invented salt discharge pipe improves the saline-alkali land, the survival rate of the plants is high and the growth speed is fast.

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 permeable layer and its application in saline-alkali land salt discharge. Background technique [0002] Saline-alkali soil refers to soil with high salinity and alkali content, which makes it difficult for plants to grow. The problem of soil salinization and secondary alkalization is a worldwide problem, which is common in the world. The problem of soil salinization and secondary salinization is more serious in coastal areas and arid and semi-arid areas. Saline-alkali hazards have made it difficult to use large areas of soil resources, and the overall agricultural production capacity has declined, seriously affecting agricultural production in many places. Today, the increasing pressure on population, food, resources, and the environment has prompted people to develop, transform, and use saline-alkali wasteland to a...
