Problems solved by technology

The soil is compacted due to high salinity, which creates resistance to drainage infiltration, air injection and temperature conduction, resulting in low soil temperature, anoxic, and slow water seepage in these areas, thus restricting the normal growth of plants
[0004] In order to meet the environmental conditions for investment, the developers of the new area usually adopt the method of replacing farmland with foreign soil, which temporarily solves the ecological garden environment of the new area. Destroying large areas of surrounding farmland will cause serious losses to my country's food production, and it does not meet the policy requirements of green and sustainable development

Embodiment Construction

[0025] A rapid treatment method for coastal saline-alkali flats, the treatment method includes the following steps:

[0026] (1) Dredging: level the determined green space, and lay 12-18cm thick soil conditioner 1 on the surface, such as figure 1 Shown; Then soil conditioner 1 is mixed evenly with the 80-90cm thick soil layer below the surface layer, so that the soil can achieve a loose and transparent effect, have the planting thickness of vegetation, and lay a good foundation for desalination, such as figure 2 shown; wherein, the soil conditioner includes the following components in parts by weight: 30-40 parts of vermicompost, 25-35 parts of peat soil, 25-35 parts of plant straw, 1-3 parts of ferrous sulfate and 2-4 parts humic acid;

[0027] (2) punching: such as image 3 and Figure 4 As shown, every interval of 50-55cm on the green space after dredging is to make a water seepage hole 3 with a diameter of 9-12cm. Fill the fine-grained stone salt 31, and then use a ro...

Abstract

The invention discloses a rapid treatment method for a coastal salt marsh. The treatment method comprises the steps of dredging, punching, desalting and improvement. The rapid treatment method has the advantages that the material structure of soil is changed through the dredging, punching and desalting steps to provide basic conditions for dewatering and desalting in the soil; through the improvement step, organic matter and nutrients are supplemented to the soil, the PH index is reduced, good water, fertilizer, air and heat conditions are provided for plant growth, overall investment cost is low, effectiveness is shown fast, operation is convenient, the soil properties of the coastal salt marsh are effectively improved, the requirement for green and sustainable development is met, and good economic and social benefits are obtained.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a rapid treatment method for coastal saline-alkali flat land. Background technique [0002] In response to the coastal development strategy, several economic development zones have been established in my country's coastal areas. These economic zones and Binhai New Area are located along the coast, and the soil conditions and groundwater conditions have brought certain difficulties to the construction of local ecological gardens. In order to promote the rapid development of the new districts, it is necessary to attract domestic and foreign merchants as soon as possible, but the desolation of the original saline-alkali flats restricts the development of these new districts. [0003] The investigation found that the reason why plants cannot grow in coastal saline-alkali flats is because the soil has high salt content, high alkali content and shall...
