摘要

As global environmental challenges intensify, enhancing forest health and soil quality has emerged as a crucial area of research. Understanding and application of beneficial bacteria in forestry industry is urgently needed as an environmentally friendly and sustainable approach. Although thousands of patents have been registered for microbial application in agriculture and forestry, the mechanisms and application of beneficial bacteria on the soil nutrient availability have not been well summarized. This review investigated the role of beneficial bacteria in tree growth, particularly their contributions to soil nutrient availability in forest trees. We summarized that beneficial bacteria significantly enhance the availability of essential elements such as nitrogen, phosphorus, potassium, and iron by promoting nutrient cycling and transformation within the soil. This process supports tree growth and improves soil quality. Additionally, beneficial bacteria facilitate plant growth by synthesizing plant hormones and inducing resistance to biotic and abiotic stresses. This review concludes by discussing practical implications of beneficial bacterial colonization and application for enhancing soil nutrient levels, along with potential future research directions. We have enriched the theoretical framework of forest-associated bacteria and provided a scientific basis that can inform forest management and ecological restoration.
