Salt elimination planting structure for improving saline-alkali soil
The salt elimination planting structure comprises a planting layer, a filtering layer, a dehydration layer, an isolation layer and a saline-alkali layer which are sequentially arranged from top to bottom, the filtering layer comprises a lower gravel layer and an upper AM fungus layer, and the gravel layer is formed by wrapping gravel with geotechnical cloth in a laying mode; the dehydration layer comprises a first-stage drainage layer, a second-stage drainage layer, a third-stage drainage layer and a fourth-stage drainage layer; and a first-stage water guide pipe layer, a second-stage water guide pipe layer and a third-stage water guide pipe layer are respectively arranged at the bottoms of the first-stage drainage layer, the second-stage drainage layer and the third-stage drainage layer. According to the method, the four-stage drainage system, the three-stage water guide system and the relatively closed saline-alkali soil improvement space are utilized, saline-alkali infiltration water is recycled to the maximum extent, long-acting saline-alkali improvement and productivity conversion can be achieved, the method is environmentally friendly, and the aim of gradually changing the saline-alkali soil into fertile farmland can be finally achieved through periodic long-term salt elimination.
本发明涉及一种改良盐碱地的排盐种植结构，包括自上而下依次设置的种植层、过滤层、脱水层、隔离层、盐碱层，所述过滤层包括下层的沙石层与上层的AM真菌层，所述沙石层由土工布包裹沙石铺设形成，所述脱水层包括第一级引流层、第二级引流层、第三级引流层、第四级引流层，所述第一级引流层、第二级引流层及第三级引流层的底部分别设有第一级导水管层、第二级导水管层、第三级导水管层。本发明利用四级引流系统和三级导水系统，以及相对封闭的盐碱地改良空间，实现盐碱下渗水最大程度的回收，不仅可以实现长效改良盐碱，转化生产力，而且环境友好，并通过周期性长期排盐，最终可以实现把盐碱地逐步变成良田的目标。
