AI Technical Summary

Technical Problem

In arid and semi-arid desert environments, traditional irrigation methods result in low water use efficiency, shallow root systems, poor wind erosion resistance, low survival rate and stability, and an inability to effectively utilize deep soil moisture.

Method used

A fixed-depth watering system using PVC pipes with seepage holes and water-absorbing expansion cylinders is adopted. By controlling the depth of water infiltration in stages, the system precisely guides the roots of plants to grow into deeper soil layers. Combined with gravity and sealing principles, it forms a deep and well-developed root network.

Benefits of technology

It significantly improves water use efficiency, enhances vegetation drought resistance and windbreak resistance, increases survival rate, forms a stable deep root system, and promotes desert ecological restoration.

Abstract

本发明公开了一种诱导沙生植被根系下渗的方法,包括选地与整地、挖坑、植被选择、PVC管施水系统设置、植被种植与回填、分层控水操作。本发明通过在植被根系附近布置带有不同深度渗水孔的PVC管,且在管内首次采用吸水膨胀圆柱块与定深挂钩‑挂环链的自降和拉升活塞结构,通过精确计算渗水孔间距、绳段长度及挂环尺寸,确保了在每个阶段,水分只能从特定目标深度的渗水孔渗出,引导根系追随水分信号不断向下深扎,形成深而发达的根系系统,实现精准的分层控水与根系定向诱导,大幅增强植被的抗旱性和抗风倒能力,且用水量少、植被成活率高、生长势好;该定深施水系统作为多功能、永固型的生态修复单元,还带有土壤换气、增湿和自清洁功能。
