What is the harm of saline-alkali soil to flowers

The physiological harm of flowers caused by saline soil is mainly as follows: if the concentration of salt in ① soil is too high, the solution concentration in the body of flowers will be lower than that outside, so that the roots can not absorb water from the soil, and the normal metabolic process will be destroyed, resulting in physiological drought of flowers and, in serious cases, plant wilting and death.

The concentration of salt in ② soil is too high. The accumulation of a large amount of salt in flowers will affect the metabolic process of flowers, lead to the accumulation of nitrogen-containing intermediates and cause cell poisoning.

③ causes drought and withering of flowers. If the concentration of salt in the soil is too high, the stomata can not be closed, a large amount of water transpiration, causing flowers to dry and wither.

④ affects the normal nutrition of flowers. Due to the competition of sodium ions, the absorption of potassium, phosphorus and other elements by flowers is reduced, and the transfer of phosphorus is also inhibited, affecting the normal nutrition of flowers, resulting in poor growth of flowers.

In the dry season of ⑤, salt accumulates in the topsoil layer, which will directly damage the tissue at the junction of the rhizome.

The harm of alkaline soil to flowers: ① alkaline soil can directly poison the roots of flowers.

When the ② is too alkaline, the physical properties of the soil deteriorate and the soil structure is destroyed, forming an alkalized layer with poor water permeability, which expands and thickens when wet and hardens when dry, so that flowers can not absorb water normally, resulting in poor growth.

The symptoms of saline-alkali soil damage are basically similar to those caused by drought, such as slow growth of flower plants, chlorosis, wilting and scorching of leaves, etc.
