AI Technical Summary

Technical Problem

When existing saline-alkali land irrigation devices irrigate the soil surface, the water infiltrates slowly into the deeper layers and evaporates easily, making it difficult to effectively leach salts from the soil below the surface. As a result, the deep salinization problem has not been adequately improved, and the treatment effect is poor.

Method used

An irrigation device for saline-alkali land remediation was designed. By setting multiple irrigation mechanisms on both sides of the main water supply pipe, including buried pipes, drip irrigation pipes, conical heads and control components, the drip irrigation pipes can be inserted into the deep soil. Combined with the water delivery components and adjustment mechanism, the water source can be controlled to penetrate into the soil at different depths, reducing water evaporation and improving the deep remediation effect.

Benefits of technology

It accelerates the penetration of water into the deep soil, fully leaches the salt in the deep soil, significantly improves the deep treatment effect of saline-alkali land, and can flexibly adjust the irrigation amount according to the degree of soil salinization, reducing water waste.

Abstract

The application discloses a kind of saline-alkali soil management irrigation devices, including water supply main pipe for water supply, multiple irrigation mechanisms are evenly distributed in the two sides of water supply main pipe;Irrigation mechanism includes embedding pipe, the inner wall of embedding pipe is fixedly connected with multiple fixed frames that are arranged at equal intervals, the inner wall of fixed frame is slidably connected with multiple drip irrigation pipes, in the present application, by setting irrigation mechanism, by embedding pipe is inserted or embedded in soil, control assembly cooperates with stretching assembly to control drip irrigation pipe from embedding pipe and cooperates with conical head and inserts into deep layer of soil, not only can improve the stability of embedding pipe, and water supply main pipe cooperates with water delivery assembly and provides water source for drip irrigation pipe, multiple-position drip irrigation pipe directly water supply to different depth soil, reduce the phenomenon that traditional surface irrigation water is slow, easy to evaporate, speed up the speed of water penetration to deep layer, can more fully leaching salt in deep layer of soil, greatly improve the effect of saline-alkali soil deep treatment.
