Embodiment 1

[0039] A method for comprehensive improvement of soil ecology in muddy coastal saline-alkali land, which consists of the following steps:

[0040] (1) Dig a ditch on the land that needs to be improved. The ditch is 0.8 m deep and 1.0 m wide, and then a water tank with a depth of 10 cm and a width of 20 cm is dug at the bottom of the ditch to lay salt drainage pipes, which are divided into trunks and the branches, the branch salt discharge pipelines are separated by 5 m, and they are all connected to the main trunk, the interval of the main trunk is 20 m, and the pipes are covered with granular stones, such as figure 1 with figure 2 shown.

[0041] (2) Lay a 10 cm thick isolation layer above the water tank, each isolation layer is 1.0 m wide, and the materials used are block and granular stones, and the diameter of the stones is controlled at 0.5 cm. The isolation layer is separated from the surrounding soil by geotextile, such as image 3 shown.

Embodiment 2

[0048] A method for comprehensive improvement of soil ecology in muddy coastal saline-alkali land, which consists of the following steps:

[0049] (1) Dig a ditch on the land that needs to be improved. The ditch is 0.8 m deep and 1.0 m wide, and then a water tank with a depth of 10 cm and a width of 30 cm is dug at the bottom of the ditch to lay salt drainage pipes, which are divided into trunks and the branches, the branch salt discharge pipelines are separated by 5 m, and they are all connected to the main trunk, the interval of the main trunk is 20 m, and the pipes are covered with granular stones, such as figure 1 with figure 2 shown.

[0050] (2) Lay a 10 cm thick isolation layer above the water tank, each isolation layer has a width of 1.0 m, and the materials used are block and granular stones, and the diameter of the stones is controlled at 1.5 cm. The isolation layer is separated from the surrounding soil by geotextile, such as image 3 shown.

[0051] (3) The ditc...

Embodiment 3

[0057] A method for comprehensive improvement of soil ecology in muddy coastal saline-alkali land, which consists of the following steps:

[0058] (1) Dig a ditch on the land that needs to be improved. The ditch is 0.8 m deep and 1.0 m wide, and then a water tank with a depth of 10 cm and a width of 40 cm is dug at the bottom of the ditch to lay salt drainage pipes, which are divided into trunks and the branches, the branch salt discharge pipelines are separated by 5 m, and they are all connected to the main trunk, the interval of the main trunk is 20 m, and the pipes are covered with granular stones, such as figure 1 with figure 2 shown.

[0059] (2) Lay a 10 cm thick isolation layer above the tank, each isolation layer is 1.0 m wide, and the materials used are block and granular stones, and the diameter of the stones is controlled at 2 cm. The isolation layer is separated from the surrounding soil by geotextile, such as image 3 shown.

Abstract

An muddy coast saline-alkali soil ecotype comprehensive improving method is provided; the method comprises the following steps: digging gutterways; digging water channels on the bottom of the gutterways; paving a salt drainage pipeline in the water channel; paving an isolation layer on the water channels; filling block and particle type rocks in the isolation layer, and using an earthwork cloth to isolate the surrounding soil; adding certain amount of an organic fertilizer-rice husk mixed material into the gutterway backfill soil; planting tree seeds vegetation having strong adaptive ability on the coastal muddy zone enclosing district original soil and improved soil. The comprehensive and vertical technical method is low in investment, cannot pollute the environment, can well process the muddy coast soil salinization problems, and is low in invest, strong in sustainability, and strong in ecological environment benefits.

Description

technical field [0001] The invention relates to the field of comprehensive improvement methods for saline-alkali tidal flats, in particular to an ecological comprehensive improvement method for saline-alkali tidal flats aimed at muddy coastal zones. Background technique [0002] In recent years, with the development of the economy and the increasingly urgent demand for land resources in urban construction, saline-alkali soil development and utilization projects have flourished. However, the characteristics of saline-alkali soil, such as high salt content, low nutrient content, and poor soil structure, seriously affect the regional agriculture and forestry. The improvement and greening of saline-alkali soil has always been an internationally recognized "worldwide problem". In order to improve the ecological conditions in coastal tidal reclamation areas, improve the efficiency of land use in coastal tidal flat reclamation areas, build ecological safety barriers in coastal tida...
