Integrating Native Plant Mixtures and Arbuscular Mycorrhizal Fungi Inoculation Increases the Productivity of Degraded Grassland

Intense human activities break the grassland–livestock balance and accelerate grassland degradation. We evaluated use of native dominant species combined with arbuscular mycorrhizal fungi (AMF) in order to recover restrain conducted a full factorial greenhouse experiment evaluate interaction effects distinct traits grass Lolium perenne (L) legume Trifolium repens (T) inoculation on productivity soil properties across non-degraded, lightly degraded, severely degraded soils. The grass–legume mixture was manipulated five ratios (T:L = 1:0, T:L 1:1, 3:1, 1:3, 0:1). results showed that L. significantly increased at different ratios, regardless AMF presence or absence. plant N P content uptake improved grasslands, especially grasslands. NO3−-N available concentrations when component from 0:1 (grass monoculture) 1:0 (legume monoculture). This may be because can promote nitrogen fixation legumes. Structural equation modeling indicated mixtures directly affected biomass, whereas biomass via providing nutrients. A quality index based minimum datasets significant positive effect artificial establishment quality. conclude planting 1:3 used production, 1:1 plus applied for nutrient accumulation stability maintenance.
