AI Technical Summary

Technical Problem

Currently, leguminous forages such as alfalfa suffer from inconsistent sowing times, low standardization of cultivation techniques, and extensive field management, resulting in unstable quality, a high rate of inferior products, and significant resource waste. This severely restricts yield and quality improvement. Meanwhile, market demand for high-quality leguminous forages is rising sharply, and existing technologies are insufficient to effectively improve their yield and quality.

Method used

A strain of Pasteurella multocida S17 and its compound inoculant were provided, which has the ability to solubilize phosphorus, fix nitrogen, produce siderophores and produce IAA. By inoculating the roots of alfalfa seedlings with the compound inoculant, alfalfa growth and development were significantly promoted, increasing plant height, root length, fresh weight and dry weight, while also increasing total nitrogen content.

Benefits of technology

It significantly increases the plant height, root length, underground fresh weight, underground dry weight, above-ground fresh weight, and above-ground dry weight of alfalfa plants, and improves the total nitrogen content, thereby enhancing alfalfa quality and yield.
