AI Technical Summary
Existing technologies cannot systematically and quantitatively assess the nitrogen competition relationship between plants and microorganisms. They lack a standardized evaluation system across ecosystems, making it difficult to reflect the intensity, direction, and process regulation characteristics of nitrogen competition. Furthermore, microbial functional information is difficult to incorporate into a unified model.
A quantitative assessment system for plant-microbe nitrogen competition is constructed. By calculating the plant-microbe nitrogen competition index (PMCI) and combining stable isotope tracing, nitrogen cycle data, and microbial functional processes, a unified competition evaluation framework is formed, including a calculation unit and a result reading unit. The system outputs the direction, intensity, and functional contribution of nitrogen competition between plants and microorganisms.
It enables a systematic and quantitative assessment of nitrogen competition between plants and microorganisms, improves the comparability and reproducibility of results across different ecosystems, and is applicable to nitrogen cycle diagnosis in ecosystems such as wetlands, grasslands, forests, and farmlands.
