Description

Salt system is arranged in normal position saline and alkaline land

Technical Field

The utility model belongs to soil improvement afforestation field especially relates to a salt system is arranged in normal position saline and alkaline land.

Background

The saline-alkali soil is a land with excessive soluble salt in soil, the reason for salinization of the land is that because the salt content of the soil and underground water is too high, under the action of strong evaporation on the earth surface, shallow underground water is conveyed to the earth surface through a capillary tube to be evaporated, the capillary tube drives the earth surface to remove the salt in the water, after the water is evaporated, the salt content of the soil rises through the capillary action and is accumulated on the surface layer of the soil, the salt content is remained in the shallow earth surface and the earth surface, and the saline-alkali soil is formed if insufficient fresh water is diluted and discharged.

Due to the accumulation of a large amount of salt in saline-alkali soil, a series of physical properties of soil are deteriorated, such as: the structure viscosity, the air permeability is poor, the volume weight is high, the hardening is compact, the soil temperature rises slowly, the activity of aerobic microorganisms in the soil is poor, the water release is slow, the permeability coefficient is low, the capillary action is strong, and the salinization of the surface soil is further aggravated. According to the water-salt movement law that salt comes with water, salt goes with water and is under water, a large amount of reclaimed water or rainwater is needed for irrigation, salt in soil is taken away, and therefore a drain pipe needs to be arranged at the bottom of planting soil.
