Embodiment 1

[0024] A method for comprehensive management of coastal saline-alkali land, comprising the following specific steps:

[0025] a. Water conservancy engineering measures: the groundwater level of saline-alkali land in coastal areas is high, so measures should be taken according to local conditions. In low-lying places, landscape pools or coastal wetlands should be excavated; in slightly higher places, trenches should be dug to lift soil, with an interval of 100 meters and a main trench with a depth of 1.5 meters. Dig drainage ditches with a depth of 0.5 meters; build a grid drainage system with connected ditches and smooth drainage and irrigation, lower the groundwater level below the critical depth, level the land, eliminate surface salt depressions, build high land ridges, plow deep in autumn Shallow plowing and early harrowing;

[0026] b. Chemical improvement measures: take sulfur, ferrous sulfate, calcium superphosphate and other quality chemical modifiers for comparison te...

Embodiment 2

[0040] A method for comprehensive management of coastal saline-alkali land, comprising the following specific steps:

[0041] a. Water conservancy engineering measures: the groundwater level of the saline-alkali land in coastal areas is high, so measures should be taken according to local conditions. In low-lying areas, landscape pools or coastal wetlands shall be excavated; in slightly higher areas, trenches shall be dug to lift soil, with an interval of 120 meters, and the depth of the main trench shall be 1.8 Dig drainage ditches with a depth of 0.5 meters; build a grid drainage system with connected ditches and smooth drainage and irrigation, lower the groundwater level below the critical depth, level the land, eliminate surface salt depressions, build high land ridges, deep plowing in autumn, and drying in spring. Shallow plowing and early harrowing;

[0042] b. Chemical improvement measures: take sulfur, ferrous sulfate, calcium superphosphate and other quality chemical ...

Embodiment 3

[0055] A method for comprehensive management of coastal saline-alkali land, comprising the following specific steps:

[0056] a. Water conservancy engineering measures: the groundwater level of saline-alkali land in the coastal area is high, so measures should be taken according to local conditions. In low-lying areas, landscape pools or coastal wetlands should be excavated; in slightly higher areas, trenches should be dug to lift soil, with an interval of 150 meters, and the depth of the main trench should be 2.0 Dig drainage ditches with a depth of 0.5 meters; build a grid drainage system with connected ditches and smooth drainage and irrigation, lower the groundwater level below the critical depth, level the land, eliminate surface salt depressions, build high land ridges, plow deep in autumn Shallow plowing and early harrowing;

Abstract

The invention discloses a coastal saline-alkali soil comprehensive treatment method. The coastal saline-alkali soil comprehensive treatment method comprises the following specific steps that a, a water conservancy project measure is taken, wherein at the low terrain, a landscape pool is excavated, or a coastal wet land is built, and at the slightly high terrain, ditching soil raising is adopted, and a network drainage system with connected irrigation canals and ditches and smooth irrigation and drainage is built; b, a chemical improvement measure is taken, wherein a chemical improver is selected to reduce the PH value of soil; c, ferment bacterial fertilizer improvement is carried out, wherein agricultural and forestall waste, straw, branches and leaves and livestock manure are locally utilized for composting ferment bacterial fertilizer, the fertilizer is applied in light, moderate and severe saline-alkali soil according to the standards of 300 kg per mu, 500 kg per mu and 1,000 kg per mu, ploughing is required while fertilization, and it is strictly avoided that the fertilizer effect is influenced by solarization and air drying; d, the measures are adjusted to local conditions, and species are matched with the site. In this way, a water conservancy measure is adopted as the foundation, microbial enzymes are adopted as a core, the chemical improver and a biological measure are adopted for assistance, the ferment bacterial fertilizer is composted through local materials, and the saline-alkali soil can be fast and efficiently improved on a large scale.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land treatment, in particular to a comprehensive treatment method for coastal saline-alkali land. Background technique [0002] my country has 18,000 kilometers of coastline and many islands, 5 million hectares of coastal saline-alkali land, 210 million mu of tidal flat resources, and very rich coastal saline-alkali soil resources. The coastal area is an economically developed area with a dense population and a high degree of urbanization in my country, and the pressure on land resources is huge. The improvement and development of coastal saline-alkali soil can not only directly alleviate the contradiction of land resource shortage, improve land utilization rate, and increase economic benefits, but also have great practical significance in maintaining ecological balance, promoting social and economic development, beautifying the environment, and maintaining ecological balance. and far-reach...
