Abstract:

The species of pterygolith were studied widely distributed on the Liaoning coastline,the effects of different concentrations of NaCl stress (0,100,200,300,400,500,600 mmol?L^-1) on the nutrient content of Suaeda salsa were studied,with a view to improving the saline-alkali land,it provided some theoretical basis for the development and utilization of materialized cultivation and economic value.The results showed that with the increase of NaCl concentration,the content of soluble sugar,protein and vitamin C in Suaeda salsa were increased first and then decreased,soluble sugar and protein treatments were higher than CK.NaCl stress promoted the accumulation of soluble sugars and proteins in the pterygotic body to maintain the osmotic balance,through osmotic regulation to resist the damage of salt,the plant could absorb water from the high salt solution under salt stress.NaCl concentration also had obvious influence on the content of Zn,Fe,Ca and Mg in Suaeda salsa.With the improvement of NaCl concentration,the content of Zn,Fe and Mg in Suaeda salsa showed a change trend after the first increase,and the change trend of Ca content continued to decrease.Among them,when NaCl concentration was 0 mmol?L^-1,the content of the PWM was the highest.When NaCl concentration was 100 mmol?L^-1,the wing base Zn and Fe content were the highest.Mg was the highest in 300 mmol?L^-1.
