摘要

This study focused primarily on ‘Muscat Hamburg’ grape varieties of the same age cultivated in the eastern foothills of Helan Mountain, China, to comprehensively assess the effects of quilted and buried soil winter treatments on grapevine growth, fruit quality, and the microorganisms of grape skins. These results indicated that both the survival rates and phenological periods of the plants subjected to the quilted and buried soil treatments were remarkably consistent. In particular, quilted treatment led to improvements in the ripening coefficient of grape fruits, accompanied by significant increases in the concentrations of tannins, total phenols, and total anthocyanins within the grape skins. Additionally, there was an increase in the total phenol contents in the grape seeds. To analyze the specific microorganisms on mature grape berry surfaces under quilt covering and soil-burying practices, high-throughput sequencing 16S and internal transcribed spacer (ITS) methods were employed. The results indicated that the effects of the cover measures facilitated notable changes in the microbial community structure, with a pronounced influence on the fungal community structure. This study serves as a valuable foundation for advancing both theoretical research and practical applications related to the replacement of conventional soil-burying techniques.
