AI Technical Summary

Technical Problem

Existing technologies lack multifunctional strains that possess multiple growth-promoting characteristics, including salt and alkali tolerance, inorganic phosphorus degradation, protease secretion, iron carrier, and the plant hormone indoleacetic acid, making it difficult to effectively improve saline-alkali soils and control plant diseases.

Method used

A strain of Pseudomonas piscicola JY2025 was isolated and identified, exhibiting significant salt and alkali tolerance, indoleacetic acid production, inorganic phosphorus degradation, siderophore secretion, and protease secretion capabilities. It can be used for crop growth and disease control in saline-alkali land.

Benefits of technology

This strain can survive stably in high salinity and alkalinity environments, reduce soil salinity and alkalinity, improve soil fertility, inhibit plant pathogens by secreting antibacterial substances, promote crop growth, and reduce disease pressure under salinity and alkalinity stress.
