Abstract:

Soil salinization has become a global issue in recent years, and is one of the most important environmental factors restricting forest growth. Therefore, it’s of great significance to understand the salt-tolerant mechanisms of trees and improve techniques of comprehensively using saline-alkali land for soil utilization and ecological environment protection. Here, we discuss effects of salt stress on forests, including growth restriction, photosynthesis inhibition, metabolism turbulence and ion imbalance, which leads to a low yield of plantation and insufficient efficiency of soil utilization. Additionally, we review the integrated system evolved by forests focusing on the host metabolic regulation and interaction with microbiota to alleviate damages to provide a theoretical basis for exploring forestation techniques and plantation cultivation on saline-alkali land.

Key words: saline-alkali land, trees, salt-tolerant mechanisms, soil microbe, forestation techniques
