Optimized fertilizer-microbe ratios enhance synergistic restoration of alpine mining ecosystems.

ABSTRACT:

Introduction

To address the critical issues of soil fertility depletion, poor vegetation establishment, and functional degradation of microbial communities in degraded alpine mining ecosystems, this study focuses on the Muli coal mine on the Qinghai-Tibet Plateau. This study systematically examined the synergistic regulatory mechanisms underlying the combined application of compound microbial inoculants and forage-specific fertilizers for restoring degraded ecosystems. The findings establish a theoretical framework and technical approach for rehabilitating fragile alpine ecosystems under extreme environmental conditions.

Methods

A three-year field experiment was conducted using a long-term plot design. Integrated assessments of vegetation performance, soil physicochemical pr
