Abstract

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).

不同牧草栽培模式对植物群落结构、土壤理化性质、微生物群落结构及功能的影响

背景与目的植物栽培模式对人工草地生产力的调节和维持起着至关重要的作用。然而，这些模式影响土壤理化性质和微生物特征的机制尚不清楚。MethodsA综合四年开展了调查分析植物的特点,土壤,微生物在三个不同的栽培模式(佐,羊的简历。青海+草豆cv。青海;中华羊茅属（Festuca sinensis）；青海+草豆cv。青海+ Poa嗜冷菌cv。青海;中华羊茅（Festuca sinensis）；青海+草豆cv。青海+ Poa嗜冷菌cv。青海+羊草品种。同德)。结果时间演替改变了禾草不同栽培模式的生产力关系。值得注意的是，这些不同的耕作方式显著影响了土壤的理化性质和微生物群落结构。比较3种栽培模式，植后3 ~ 4年，ZC栽培模式能维持较高的地上生物量。此外，ZC模式对提高土壤肥力和促进有益微生物的积累有积极的促进作用，从而促进植物生长的有利环境。ZC模式下土壤pH值显著低于CLZ和TZCL模式，减缓了土壤的盐碱化趋势。

期刊介绍： Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
