Embodiment 1

[0046] Take the street tree greening project in Tianjin Binhai New Area as an example. Specifically, it includes slotting, horizontal salt drainage system construction, vertical salt drainage ventilation system construction, saline-alkali soil structure improvement and backfilling, irrigation and leaching, soil fertilization and seedling planting and maintenance, etc.

[0047] Grooving: The excavator excavates the planting groove, the soil is placed on the roadside non-woven fabric, the groove width is 1.2m, and the groove bottom is 45cm higher than the groundwater level; the groove bottom is manually trimmed and leveled, the groove bottom flatness is within ±3cm, and the groove bottom pressure Solidity ≥ 80%;

[0048] Construction of horizontal salt drainage system: Lay a vertical salt drainage pipe in the center of the tank bottom to ensure that the slope of the salt drainage pipe along the water flow direction is 0.1%; The root canal is about 100m long; the outlet end of t...

Abstract

The invention relates to a method for fast and efficient improvement greening of coastal saline soil. The method comprises a step 1) of digging a planting trough, a step 2) of laying a horizontal salt drainage system; a step 3) of laying a vertical salt drainage ventilation system; a step 4) of performing soil structure improvement; a step 5) of performing irrigation leaching and a step 6) of performing soil fertility improvement and nursery stock transplanting maintenance. According to the method, the leaching efficiency and a desalting effect of the coastal saline soil are improved. By adoption of the method, horizontal and vertical motion of irrigation leaching water in soil can be improved, irrigation leaching water salt leaching efficiency and drainage and desalting efficiency of the horizontal and vertical salt drainage systems are improved, and the saline soil improvement time is shortened.

Description

technical field [0001] The invention relates to a method for afforesting saline-alkali land, in particular to a method for rapid and efficient improvement of original soil in coastal saline-alkali land. Background technique [0002] There are a large number of coastal saline-alkali lands in my country's coastal areas. Coastal saline-alkali land has low terrain, high soil salinity, and high groundwater level, which restrict the development and utilization of coastal saline-alkali land resources and the construction of regional ecological environment. The coastal area is the most densely populated and most economically developed area in my country. Scientific, ecological, and efficient management of coastal saline-alkali land is of great significance to improving the ecological living environment in coastal areas and promoting sustainable social and economic development. [0003] Affected by the special site environment and soil conditions, coastal saline-alkali soil improvem...
