Device for ecologically improving salinity of seashore saline land

Abstract

The invention discloses a device for ecologically improving the salinity of a seashore saline land. The device for ecologically improving the salinity of the seashore saline land comprises a rack, wherein the rack comprises two vertical supports and a horizontal support positioned between the vertical supports; mounting openings which are opposite are formed in positions, which are positioned below the horizontal support, of the two vertical supports; a rotating shaft is rotatably arranged in each mounting opening in a penetrating manner; a plurality of soil loosening knives are arranged on each rotating shaft; one end of each rotating shaft is connected with a first motor which is used for driving the rotating shaft to rotate; each soil loosening knife comprises a knife body and a connecting rod; one end of each connecting rod is fixedly connected with the corresponding rotating shaft; a threaded hole is formed in an end surface of the other end of each connecting rod; and a connecting end of each knife body is provided with a threaded connecting column which extends into the corresponding threaded hole and is in threaded connection with the corresponding threaded hole. By the device, the seashore saline land is cultivated and applied with fertilizers to improve the salinity of the seashore saline land, the soil of the saline land is improved favorably, the utilization rate of the saline land is increased, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a device for ecologically improving the salinity of coastal saline-alkali land. Background technique [0002] There are large areas of saline-alkali land distributed in our country, and the degree of salinization is expanding, such as coastal areas. Coastal saline-alkali land is mostly high-sodium-salt muddy marine extremely fine-grained clay, with poor soil permeability, and the surface soil quickly forms compaction after being soaked by precipitation or irrigation water, the soil infiltration capacity is further reduced, and water is easy to form under heavy rain or rainstorm conditions. Due to the blocking of the dense silt and silt layer of the soil, the proportion of water infiltrated into the soil to wash the salt and discharged through the hidden pipe is relatively low, and the effect of fast desalination of the dark pipe is not obvious; the hy...

AI Technical Summary

Problems solved by technology

[0004] Among them, when the soil is improved by tillage and fertilization, since the surface soil is soaked by precipitation or irrigation water, it will quickly form compaction, so when tillage and fertilization, if it is completely dependent on manual tillage, it will take time and effort, and the area of ​​saline-alkali land is relatively large , the workload of farming and fertilization is relatively large, which brings greater labor intensity to workers and lower efficiency
