Other claims from this paper (15)
- Intervention effect Mixed forest soils had 120.10% higher nitrate nitrogen content than CLS forests.
- Intervention effect Urease activity in mixed forest soils increased by 123.99% relative to CLP forests.
- Intervention effect Urease activity in mixed forest soils increased by 49.56% relative to CLS forests.
- Intervention effect Mixing significantly altered the rhizosphere microbial community structure.
- Intervention effect In mixed forests, nitrogen-fixing and potentially phosphorus-solubilizing bacteria of the genera Paraburkholderia and Burkholderia increased in abundance.
- Observation The arbuscular mycorrhizal fungus Rhizophagus showed absolute dominance of the fungal community, with relative abundance from 14.84% to 88.81%.
- Intervention effect Genes associated with denitrification and phosphorus starvation regulation were significantly upregulated in mixed forests.
- Intervention effect Phosphorus starvation regulation genes were 18.84% more abundant in HJSs than in CLSs.
- Observation The proportion of positive correlation edges in the HJP nitrogen cycling network reached 75.0%.
- Intervention effect The average degree of the HJS phosphorus cycling network (2.691) surpassed that of CLS.
- Association In mixed forests, the association strength between fungi and phosphorus cycling genes reached R2 = 0.915, significant at p < 0.01.
- Association In pure forests, the association strength between fungi and phosphorus cycling genes was R2 = 0.213.
- Mechanism Mixed planting transforms nutrient cycling from a resource-competitive mode to a microbially synergized mode.
- Mechanism The synergistic rhizosphere microbial effect is a key internal mechanism for overcoming nutrient bottlenecks.
- Recommendation The synergistic rhizosphere microbial effect should serve as a diagnostic indicator of soil recovery in degraded pine forests.
