The implementation of inter-row cover crops is considered a promising alternative ecological solution for sustainable agriculture, because they have been proven to be effective in improving soil structure, increasing soil fertility, controlling pests and diseases, enhancing biodiversity and to regulate excessive vine growth. However, the effects of vineyard inter-row cover crops on grape microbial community during maturity period remain unknown. This work used high-throughput sequencing technology in 2021 to investigate the effect of inter-row cover crops on the diversity of grape microbial community during maturity period. First, inter-row cover crops changed the grape microclimate and the diversity and structure of grape microbial community; second, compared with clear tillage, the assembly process of grape microbial community at the grape harvest, and the interactions between species within the microbial community changed; finally, there was a strong correlation between grape microbial species and microclimate factors. Taken together, this work provides important insights into the effects of vineyard inter-row cover crops on the diversity of grape microbial communities during the maturity period, and contributes to improve vineyard management techniques.
行间覆盖作物的实施被认为是可持续农业的一种有前途的生态替代方案，因为它们已被证明在改善土壤结构、提高土壤肥力、控制病虫害、增强生物多样性和调节过度藤本生长方面非常有效。然而，葡萄园行间覆盖作物对成熟期间葡萄微生物群落的影响尚不清楚。本研究于 2021 年使用高通量测序技术，调查行间覆盖作物对成熟期间葡萄微生物群落多样性的影响。首先，行间覆盖作物改变了葡萄微气候和葡萄微生物群落的多样性和结构；其次，与清耕相比，葡萄收获时葡萄微生物群落的组装过程以及微生物群落内物种之间的相互作用发生了变化；最后，葡萄微生物物种与微气候因素之间存在很强的相关性。总之，本研究为葡萄园行间覆盖作物对成熟期间葡萄微生物群落多样性的影响提供了重要的见解，并有助于改进葡萄园管理技术。
