Hierarchical greening method suitable for saline-alkali soil
The invention relates to a hierarchical greening method suitable for saline-alkali soil. The method comprises the following steps that S1, planning of a greening area and a water storage area; S2, excavation of the greening area: digging grooves with the depth being 1 m in soil of the greening area; S3, laying of concealed pipes in the greening area: laying the concealed pipes in the grooves, enabling the ends of the concealed pipes to extend to the water storage area, and forming a plurality of water collecting holes in the tops of the concealed pipes; S4, excavation of the water storage area: downwards deeply digging a reservoir with the depth being 2 m deeply in the water storage area; S5, soil backfilling of the greening area: completely backfilling the dug soil into the greening area; S6, washing out of saline-alkali substances in the soil: spraying water to the soil for cleaning in a manual spraying mode; S7, neutralization treatment on the water in the reservoir: adding an acidifying agent into the reservoir for neutralization treatment; and S8, recycling of the water in the reservoir. The hierarchical greening method has the advantages that the saline-alkali soil is improved in situ, the growth requirements of green plants are met, and bottom layer saline-alkali reverse osmosis and secondary pollution to soil in other regions are avoided.
本申请涉及一种适用于盐碱地的层级式绿化方法，其包括如下步骤：S1、规划出绿化区和蓄水区；S2、开挖绿化区：在绿化区的土壤深挖至1m深的凹槽；S3、绿化区内铺设暗管：将暗管铺设于凹槽内，暗管的端部延伸至蓄水区，暗管的顶部开设有多个集水孔；S4、开挖蓄水区：将蓄水区向下深挖出2m的蓄水池；S5、绿化区回填土壤：将挖出的土壤完全回填于绿化区；S6、洗出土壤中的盐碱物质：人工喷淋的方式向土壤喷水清洗；S7、对蓄水池中的水中和处理：向蓄水池中加入酸化剂进行中和处理；S8、对蓄水池内的水循环利用。本申请具有就地改良盐碱地土壤、满足绿化植物的生长需求、避免了底层盐碱反渗和对其他地区土壤造成二次污染。
