A seedling raising base is a base for planting and cultivating green seedlings, potted flowers and fruit and vegetable seedlings by applying a scientific cultivation method and a modern scientific management mode on the premise of protecting and improving the ecological environment. The salinization of the soil is one of the problems of planting and cultivating crops in seedling raising bases, and means that the soil has high salt content, so that the soil is hardened and the fertility is reduced, and therefore, the crops are difficult to absorb nutrients and the growth of the crops is hindered. There are two main conditions for the formation of land salinization: one is high underground water level and climate drought, and the other is low-lying, and no drainage path exists. Because the groundwater contains a certain amount of salt, if the groundwater is close to the ground and the area is dry, the groundwater rising to the ground surface under the capillary action evaporates, and the salt is continuously accumulated on the surface layer of the soil, thereby causing the salinization of the soil.

In the related art, water conservancy irrigation measures are often adopted to reduce the salinity in the soil, that is, water is irrigated into the soil to dissolve and dilute the salinity in the soil, so that the purposes of washing the salinity in the soil and adjusting the salinity of the soil are achieved while the requirement of crops on water is met.
