Coastal saline-alkali soil engineering improvement system and method
The invention discloses a coastal saline-alkali soil engineering improvement system and method thereof. The system comprises a large pit dug in saline-alkali soil, a salt drainage ditch formed in thebottom of the pit, an isolation layer arranged in the large pit, all the side walls, the bottom and the salt drainage ditch of the pit are fully paved with the isolation layer, and a planting soil layer, an original soil layer and a salt drainage layer are sequentially arranged in the large pit from top to bottom. According to the system and the method, the effects of cutting off a saline water infiltration channel, rapidly discharging salt, reversely infiltrating and fully utilizing original soil resources are achieved, the purposes of improving the quality of the severe saline-alkali soil, increasing the survival rate of greening plants and improving the greening level of the severe saline-alkali soil are rapidly achieved at low cost, and salt returning of a saline-alkali soil layer to aplanting soil layer is avoided.
本发明公开了一种滨海盐碱土工程改良系统及方法，包括在盐碱土内挖出的大坑，坑底设置有排盐沟，大坑内设置隔离层，所述隔离层铺满坑的所有侧壁、坑底和排盐沟，大坑内从上到下依次设置有种植土层、原土层、排盐层。本发明系统和方法实现了切断咸水入渗通道、快速排盐反渗及充分利用原土资源的效果，用较低成本快速达到改善重度盐碱地质量，提高绿化植物成活率，提高重度盐碱地绿化水平的目的，并且不会导致盐碱土层返盐至种植土层。
