Dragon bamboo (Dendrocalamus giganteus) is a giant sympodial bamboo species widely distributed in Asia. However, it remains unclear how dragon bamboo and soil microbes interact to affect soil properties. In this study, we investigated the planting patterns (semi-natural and artificial) on different slopes (sunny and shady) to determine the effects on soil properties and microbial community. The results showed that the soil in which dragon bamboo was grown was acidic, with a pH value of ~5. Also, the soil organic matter content, nitrogen hydrolysate concentration, total nitrogen, available potassium, and total potassium of the dragon bamboo semi-natural forest significantly improved, especially on the sunny slope. In contrast, the available phosphorus level was higher in the artificial bamboo forest, probably owing to the phosphate fertilizer application. The bacterial and fungal diversity and the bacterial abundance were all higher on the sunny slope of the semi-natural forest than those in the other samples. The microbial operational taxonomic units (OTUs) shared between the shady and sunny slopes accounted for 47.8–62.2%, but the core OTUs of all samples were only 24.4–30.4% of each sample, suggesting that the slope type had a significant effect on the microbial community. Some acido-philic microbes, such as Acidobacteria groups, Streptomyces and Mortierella, became dominant in dragon bamboo forest soil. A PICRUSt analysis of the bacterial functional groups revealed that post-translational modification, cell division, and coenzyme transport and metabolism were abundant in the semi-natural forest. However, some microorganisms with strong stress resistance might be activated in the artificial forest. Taken together, these results illustrated the influence of dragon bamboo growth on soil physicochemical property and microbial community, which might help understand the growth status of dragon bamboo under different planting patterns.

龙竹（Dendrocalamus giganteus）是一种在亚洲广泛分布的巨大的sym竹种类。然而，尚不清楚龙竹与土壤微生物如何相互作用以影响土壤特性。在这项研究中，我们调查了不同坡度（晴天和阴凉处）的种植方式（半天然和人工），以确定对土壤特性和微生物群落的影响。结果表明，生长龙竹的土壤呈酸性，p​​H值为〜5。同样，龙竹半天然林的土壤有机质含量，氮水解物浓度，总氮，有效钾和总钾显着改善，尤其是在阳光明媚的斜坡上。相反，人造竹林中的有效磷水平较高，这可能是由于施用了磷肥。在半天然林的向阳坡上，细菌和真菌的多样性以及细菌的丰度都高于其他样品。阴坡和阳坡之间共享的微生物操作分类单位（OTU）占47.8–62.2％，但所有样品的核心OTU仅占每个样品的24.4–30.4％，这表明斜坡类型对土壤样品具有显着影响。微生物群落。一些嗜酸性微生物，例如酸性细菌群，提示坡度类型对微生物群落有显着影响。一些嗜酸性微生物，例如酸性细菌群，提示坡度类型对微生物群落有显着影响。一些嗜酸性微生物，例如酸性细菌群，链霉菌和莫氏菌在龙竹林土壤中占主导地位。对细菌功能基团的PICRUSt分析显示，半天然林中翻译后修饰，细胞分裂以及辅酶运输和代谢丰富。但是，某些具有较强抗逆性的微生物可能会在人工林中被激活。综上所述，这些结果说明了龙竹生长对土壤理化性质和微生物群落的影响，可能有助于了解不同种植方式下龙竹的生长状况。
