To prevent plants from being damaged due to extreme temperature and sunlight, the pitaya orchards in Hainan Province, China, are increasingly adopting living and black fabric cloth mulching. In this study, an Illumina Hiseq sequencer was employed to compare the soil microbial communities of two pitaya orchards, one covered by living mulching (LM) and the other covered by black fabric cloth (FC). Bacterial abundance was higher in the LM orchard than in the FC orchard (1.19 × 10 versus 4.49 × 10 g soil). In contrast, fungal abundance was higher in the FC orchard than in the LM orchard (2.71 × 10 versus 2.97 × 10 g soil). We also found that the most dominant species in the FC orchard were from the genus Neoscytalidium, which included species that could cause infection in a large variety of plant hosts. However, the LM orchard mainly harbored useful fungal species, such as Trichoderma and Chaetomium. Soil nutrients were positively correlated in the FC orchard, which potentially indicated that the FC orchard could demonstrate better fertilizer utilization efficiency. However, the LM and FC strategies have both advantages and disadvantages with regards to the cultivation management of pitaya orchards.
为了防止植物因极端温度和阳光而受损，中国海南省的火龙果果园越来越多地采用活体和黑色织物覆盖。在这项研究中，使用 Illumina Hiseq 测序仪比较了两个火龙果果园的土壤微生物群落，一个覆盖活体覆盖物（LM），另一个覆盖黑色织物布（FC）。活体覆盖果园的细菌丰度高于黑色织物布果园（1.19×10 比 4.49×10 g 土壤）。相比之下，黑色织物布果园的真菌丰度高于活体覆盖果园（2.71×10 比 2.97×10 g 土壤）。我们还发现，黑色织物布果园中最主要的物种来自 Neoscytalidium 属，其中包括能感染多种植物宿主的物种。然而，活体覆盖果园主要栖息着有用的真菌物种，如 Trichoderma 和 Chaetomium。黑色织物布果园中的土壤养分呈正相关，这可能表明黑色织物布果园的肥料利用率更高。然而，活体覆盖和黑色织物布覆盖策略在火龙果果园的栽培管理方面都有各自的优缺点。
