Embodiment Construction

[0020] The present invention is described in detail below in conjunction with accompanying drawing.

[0021] A treatment and utilization method of silty coastal saline soil is carried out as follows:

[0022] 1. Establish a water supply system:

[0023] Generally, land leveling before soil treatment is carried out in April. Use bulldozers and excavators to level the land; according to the needs of washing salt with fresh water and watering plants before planting, dig fresh water wells, install water pumps and supporting cables, and lay water supply pipelines. The water supply pipeline adopts DE125 pipeline and DE50 pipeline, and the buried depth is 1m.

[0024] 2. Establish a drainage and salt shower system (see figure 1 ):

[0025] In May, in the soil treatment area, excavate a salt-spraying drainage ditch 1 with a width of 2m at the top, 1m deep and 1m at the bottom of the ditch. The distance between the ditch is 20m, forming a small terrace. The depth should reach the ...

Abstract

The invention relates a treatment and utilization technology of saline soil resources, in particular to a treatment and utilization method of muddy seashore saline soil. The method comprises the following steps of: establishing a water supply system consisting of a fresh water well, a water pump and a water supply pipe; excavating a salt leaching drainage ditch so as to establish a drainage salt leaching system; applying a cow dung and crop stalk fertilizer and a phosphogypsum soil and fertility improving fertilizer; with a small raised field as unit, irrigating fresh water to wash and leach salt; and planting and maintaining vegetation through cultivating the land by machine, sunning the upturned soil, planting the vegetation and irrigating the vegetation, wherein a planting technology with gradient increasing salt tolerance is adopted in planting the vegetation. According to the invention, for the salinity and structural characteristics of the muddy seashore saline soil, the muddy seashore strongly salined soil in the coastal zone is treated and utilized in combination with engineering measures, physical measures and chemical measures on the basis of salt tolerant plant appraisal; and The treatment and utilization method of the muddy seashore saline soil provided by the invention has the advantages of simplicity in operation, resource conservation, soil treatment and utilization cost of less than 166.21 yuan/m2 and plant survival rate of more than 90%.

Description

[0001] Technical field: [0002] The invention relates to a technology for harnessing and utilizing saline soil resources, in particular to a method for harnessing and utilizing muddy coastal saline soil. Background technique: [0003] According to the classification standard of saline-alkali soil in coastal areas of my country (0-100cm), saline-alkali soil with a total salt content of 1 meter of soil > 0.6% is coastal saline soil. The muddy coastal zone around the Bohai Sea is mostly unstructured coastal saline soil, with high salt content, heavy soil texture, weak salt leaching, and poor effect of traditional fresh water salt pressing; the surface layer has a salt content of 1.5-2.5%, and some can reach 4 % or more, the average salt content in 1m soil layer is 0.6-2%; the groundwater level is high (about 0.6-1.5m); the groundwater salinity is high (average salinity is 11.8 g / l-33.7g / l). The harsh soil environment of coastal silt and saline soil is not conducive to the ...
