In this study, we used 7-year-old dwarf middle-stock apples as the test materials to study the effect of tree disk covered with different materials (waterproof, water-permeable horticultural ground fabrics and plastic film) on the soil microbial abundance, community structure and diversity. High-throughput sequencing results showed that three different types of horticultural ground cloth could increase the relative abundance of Proteobacteria of 0-20 cm soil layer, Proteobacteria abundance of the 20-40 cm soil layer covered by waterproof gardening cloth and plastic film were improved as well as. The results of microbial diversity showed that the horticultural ground fabrics and plastics film all changed the soil bacteria A (Ace), C (Chao 1) and S (Simpson) index. Among them, the permeable horticultural ground fabrics changed the indicators above most significantly, followed by the waterproof horticultural ground fabrics and plastics film. In addition, the permeable gardening cloth significantly reduced the soil fungal A, C and S index. The result of clustering relationship was consistent with the result of diversity, which was also the most obvious change of soil microbial community structure in permeable ground fabrics. Comprehensive analysis showed that different mulching were conducive to improving the richness and diversity of soil bacterial communities, reducing the richness and diversity of soil fungal communities, and optimizing the structure of soil microbial communities. Among them, permeable horticultural ground cover had the optimal effect.
