摘要

Background and aims

Plant cultivation patterns play a crucial role in regulating and maintaining the productivity of artificial grasslands. However, the mechanisms by which these patterns influence soil physicochemical properties and microbial traits remain unknown.

Methods

A comprehensive 4-year investigation was conducted to analyze the characteristics of plants, soils, and microorganisms under three distinct cultivation patterns (ZC, Festuca sinensis cv. Qinghai + Poa pratensis cv. Qinghai; CLZ, Festuca sinensis cv. Qinghai + Poa pratensis cv. Qinghai + Poa crymophila cv. Qinghai; TZCL, Festuca sinensis cv. Qinghai + Poa pratensis cv. Qinghai + Poa crymophila cv. Qinghai + Elymus sibiricus cv. Tongde).

Results

The findings showed that the temporal succession altered productivity relationships of different cultivation patterns of grasses. Notably, these diverse cultivation patterns significantly influenced the soil's physicochemical properties and microbial community structure. When comparing the three cultivation patterns, the ZC cultivation pattern sustained a relatively high aboveground biomass for 3–4 years following planting. Moreover, ZC pattern positively contributed to enhancing soil fertility and fostering the accumulation of beneficial microorganisms, thereby promoting a conducive environment for plant growth. Soil pH was significantly lower in the ZC pattern than in the CLZ and TZCL patterns, mitigating the soil's tendency toward salinization. 

Conclusions

The ZC cultivation pattern emerges as the most favorable choice for the sustainable management of artificial grasslands in the Qinghai-Tibet Plateau (QTP).
