What harm does saline-alkali soil do to flowers?

The main physiological harms to flowers caused by saline soil are: (1) When the salt concentration in the soil is too high, the solution concentration inside the flower plant becomes lower than that outside, so the roots cannot absorb water from the soil, the normal metabolic process is disrupted, causing physiological drought in the flowers, and in severe cases causing the plant to wilt and die.

(2) When the salt concentration in the soil is too high. A large amount of salt accumulates in the flower plant, which affects the flower's metabolic process, leading to the accumulation of nitrogen-containing intermediate products and poisoning the cells.

(3) Causing drought and wilting of flowers. When the salt concentration in the soil is too high, the stomata cannot close, water is transpired in large amounts, causing drought and wilting of the flowers.

(4) Affecting the normal nutrition of flowers. Due to competition from sodium ions, the flower's absorption of potassium, phosphorus and other elements is reduced, and the transfer of phosphorus is also inhibited, affecting the normal nutrition of the flowers and causing poor growth.

(5) In dry seasons, salts accumulate in the surface soil layer, directly damaging the tissue at the junction of roots and stems.

The harm of alkaline soil to flowers: (1) Alkaline soil can directly poison the root system of flowers.

(2) When the soil is too strongly alkaline, its physical properties deteriorate, the soil structure is destroyed, and an alkalized layer with extremely poor water permeability is formed, which swells and becomes sticky when wet and hardens and cakes when dry, so that flowers cannot absorb water normally, resulting in poor growth.

The symptoms shown by the harm of saline-alkali soil are basically similar to those caused by drought, causing flower plants to grow slowly, with leaves chlorotic, wilting and scorched.
