Optimization planting method suitable for plant saline-alkali soil greening

The invention relates to an optimization planting method suitable for plant saline-alkali soil greening. The optimization planting method is used for solving the problem that seedlings in a severe saline-alkali soil area are not easy to survive; different plants are selected in different environments by controlling the physicochemical properties of soil and are planted in a regular and natural combined manner, so that the interlacing effect of group planting of the different plants is achieved, the beautiful shape and charm of the plants are shown, the combination of megaphanerophytes, under-forest shade shrubs and ground covers is used as the characteristic, the hierarchy of plant communities is emphasized, and the ecological landscape effect is highlighted; and some waste is used as a nutrient for nursery stock growth, so that the method is environmentally friendly, and meanwhile, the survival rate of the seedlings can be greatly improved. 本发明涉及一种适用于厂区盐碱地绿化优化种植的方法，用于解决重度盐碱地区域苗木不易存活的问题，通过控制土壤的理化性质后，在不同的环境下选择
