Description

Salinity Measuring Device {APPARATUS FOR DETECTING SALINITY}

The present invention relates to a salinity measuring apparatus, and more particularly to a salinity measuring apparatus that can always obtain a constant salinity value.

In general, land reclamation refers to the creation of embankments on lakes or beaches, the extraction of water within them, and the land reclamation into agricultural land or other industrial sites.

Particularly, reclamation of sea level aims to use seabed soil as arable land for sea level near the estuary of estuary of big river or big sea tide, but various salts are used in sea water. Since the large amount of iii) is contained, the solution to remove the salt has emerged as an important challenge.

In land-based initial reclaimed soils, salt content is generally about 1% per weight of wind-dried soils due to salt, and sometimes 5-10% of surface soils. According to the effect of the salt concentration in the soil water on crop growth, for example, rice yields 0.17% daily yield decrease by 15%, and 0.33% yields 30% water loss. Iii), and when it is 0.5%, it is reported that it is not viable. In the case of barley, the germination is slightly delayed at 0.125%, and at 0.25%, it is germinated, and early growth is very poor, but soon recovers, and it is not affected by the later growth. When the harvest showed little to see.

In addition, the salt damage was found to be more severe in the reproductive growth period than in the trophic growth period of rice.

As a countermeasure against salt damage, the salt value (salt concentration) should be measured, and if the salt value is higher than the set salt value as a result of the measurement, the salt value should be reduced by decontamination. Decontamination methods include freshwater decontamination and osmotic decontamination.
