[0002] Saline-alkali land is a type of salt accumulation, referring to the situation where the salt content in the soil affects the normal growth of crops. The characteristics of saline-alkali land mainly include easy water stagnation in the soil, poor air permeability, poor water permeability, slow land warming, low enzyme activity in the soil, slow transformation of organic matter, poor soil fertility, easy hardening, low permeability coefficient, etc. These characteristics together lead to the unsuitability of saline-alkali land, hinder engineering construction, damage the ecological environment, and affect agricultural and forestry production.

[0003] Currently, the commonly used method for improving saline-alkali land is to water and desalt the soil to reduce the soil salt content, and then plant salt-tolerant plants to achieve the purpose of soil improvement. However, the salt content of saline-alkali land in different regions is different, and different seedlings need to be selected to improve the survival rate of seedlings. For this, the method of container seedling cultivation is currently used to cultivate seedlings, and certain effects have been achieved.
