Abstract

The invention discloses a coastal saline-alkali soil terrace type afforesting method for improvement of dredger fill. The coastal saline-alkali soil terrace type afforesting method for improvement of the dredger fill comprises water seepage ditches, foundation terrain dredger fill, straw curtains, geotechnical cloth, improved planting soil, local models and the like, wherein square seepage ditches of the water seepage ditches are longitudinally excavated in the lowest position of the foundation terrain dredger fill, particle-size ballast stones are filled into the square seepage ditches, the distance between the foundation terrain dredger fill and the ground is 1-1.5m, the gradient of the foundation terrain dredger fill is 15 degrees to 30 degrees, straw is distributed on the foundation terrain dredger fill, the geotechnical cloth is laid on the straw curtains, and then the improved planting soil is laid on the geotechnical cloth. Due to the fact that the coastal saline-alkali soil terrace type afforesting method for improvement of the dredger fill is combined with the terrace type shape, the coastal saline-alkali soil terrace type afforesting method for improvement of the dredger fill is beneficial to retaining rainwater, enables salinity to be effectively leached and reduced, is beneficial to fertilizer and soil conservation, and enables the survival rate of landscape plants to be more than 90%, the waste is effectively utilized, natural resources are protected, and afforesting cost is reduced by more than 50%.

Description

technical field

[0001] The invention belongs to the technical field of landscaping engineering, and relates to a method for designing landscaping, in particular to a greening method for improving coastal saline-alkali land terraced fields by dredging and filling. Background technique

[0002] The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. As one of the main types of saline-alkali land in my country, coastal saline-alkali land has the characteristics of large area, large regional differences, and difficulty in improvement. In particular, the afforestation of the original saline-alkali soil and dredger fill in the coastal area has always been a problem that has plagued the greening construction of the port for a long time. In the past, the landscaping in the port area mostly adopted ...
