Moss grows in the greenhouse. Moss is a halophilic algae, and red moss is a sign of soil salinization, which shows that soil salinization is very serious, mainly due to continuous greenhouse operation, and a large number of inorganic fertilizers are applied all year round, which is caused by the high concentration of inorganic salts on the surface. 1 It is suggested that salt should be leached by pressing alkali under high pressure, and a large amount of organic active bacterial fertilizer or crop straw should be applied to the soil after deep ploughing, and organic natural active silicon should be applied to melt the soil and improve the soil.
