Taking the summer black grape as the sample, the effects of different mulching materials on soil microbe and grape growth in rain-shelter vineyards were studied. The results indicated that, compared with the control check (CK), by CM, WM and RM treatment, the number of fungi and bacteria in 0~40 cm soil layer could be increased and soil actinomycetes could be reduced; soil microbial biomass carbon and soil microbial quotient under the four mulching materials were all higher than CK, while microbial metabolic quotient was lower than the control; soil organic carbon under CM, WM and RM treatment showed a decreasing trend and under SM treatment was on the contrary; SM and CM treatment could increase soil respiration intensity, and WM and RM treatment were on the contrary; the four mulching materials could increase the grape root activity, promote the growth of grape leaves and new shoots, and improve the internal and external quality of grape. The quantity and activity of soil microorganism under SM treatment were the strongest, whose total microbial biomass, soil microbial biomass carbon, soil microbial quotient and soil respiration intensity significantly increased by 20.27%, 51.43%, 40.38%, and 13.52%, respectively, while soil microbial metabolic quotient significantly decreased by 22.51% compared with the control; Grape fruit quality was better under SM and RM treatment, but no significant difference was found between them. Compared with the control, the soluble solids of SM and RM treatment significantly increased by 14.25%, and 17.74%, respectively. The experiment results provided theoretical and practical references for the selection of mulching materials in rain-shelter vineyards. %U https://www.hnxb.org.cn/EN/10.11869/j.issn.100-8551.2021.02.0471
