Wilson (), originated in the Minjiang River basin in Sichuan, China, has different phenotypic characteristics in different environments. To analyze the correlation between the phenotypes of and its soil micro-ecological environment, wild habitat soil of at the two altitudes were selected to analyze the diversity and community structure of microorganisms in soil, and measure the soil physicochemical factors and enzyme activities. The structural composition and diversity of fungal and bacterial communities in hillside and valley soils were significantly different (< 0.01). Soil available potassium (AK) and soil enzyme activities such as urease (S_UE), sucrase (S_SC), and catalase (S_CAT) differed significantly different between hillsides and valleys ( < 0.01), while organic matter (OM), total phosphorus (TP), and polyphenol oxidase (S_PPO) had no great variances. Correlation analysis was conducted between the common and differential microorganisms and the morphological characteristics, soil physicochemical factors and soil enzyme activities of in both hillside and valley. The results showed that both of the fungal and bacterial could be clustered into two distinct groups by positive and negative correlations, suggesting that the representative microorganism may have structural characteristics that are directly related to soil physicochemical properties and enzyme activities, which conversely affect the phenotype of Lily. Therefore, the study on the native species of horticultural plants and the local soil microhabitat environment will benefit the conservation of wild Lily and provide theoretical guidance for the domestication and breeding of horticultural plants.
威尔逊兰，原产于中国四川岷江流域，在不同的环境中有不同的表型特征。为了分析威尔逊兰表型与其土壤微生态环境的相关性，选择了两种不同海拔的野生栖息地土壤，分析土壤微生物多样性和群落结构，并测定土壤理化因子和酶活性。山坡和山谷土壤中真菌和细菌群落的结构组成和多样性存在显著差异（<0.01）。山坡和山谷土壤中速效钾（AK）和土壤酶活性（如脲酶（S_UE）、蔗糖酶（S_SC）和过氧化氢酶（S_CAT））差异显著（<0.01），而有机质（OM）、总磷（TP）和多酚氧化酶（S_PPO）则没有很大的差异。对山坡和山谷土壤中常见和差异微生物与威尔逊兰形态特征、土壤理化因子和土壤酶活性进行了相关性分析。结果表明，山坡和山谷土壤真菌和细菌均可通过正相关和负相关聚类为两个明显不同的组，表明代表性微生物可能具有与土壤理化性质和酶活性直接相关的结构特征，而这些特征反过来又影响百合的表型。因此，对园艺植物本地种和当地土壤微生境环境的研究将有利于野生百合的保护，并为园艺植物的驯化和选育提供理论指导。
