The application of herbicides to arable land is still the most effective and accepted method to protect plants from weeds. Extensive use of chemicals in conventional agricultural practices has resulted in continuous and serious environmental pollution. Flurochloridone (FLC) is a monophenyl pyrrolidinone selective herbicide that is commonly used to inhibit weeds that occur during the growth of potatoes. In recent years, research on the toxicity of FLC has gradually increased. However, it is relatively rare to analyze the role of FLC by studying the composition of soil microorganisms. Therefore, we used NGS methods to identify the fungal community structure of the low content soil (LS) and high content soil (HS) samples in this study. Subsequently, we identified the fungal community and composition differences of these two group samples using the statistical analysis. Despite the variances of fungal community and composition across the different samples within the group, the fungal composition of the LS samples and the HS samples. LS samples were predominated by , while the HS samples were predominated by and . The major species in the LS samples were and , whereas the dominant species in the HS samples were and . These results suggested that the LS samples and the HS samples had different rhizosphere soil fungal community and composition changes resulting from implementation of FLC in potato growing areas.
将除草剂应用于耕地仍然是保护植物免受杂草侵害最有效且被广泛接受的方法。在传统农业实践中大量使用化学品已导致持续且严重的环境污染。氟咯草酮（FLC）是一种单苯基吡咯烷酮类选择性除草剂，常用于抑制马铃薯生长期间出现的杂草。近年来，关于FLC毒性的研究逐渐增多。然而，通过研究土壤微生物组成来分析FLC的作用相对较少。因此，在本研究中我们使用二代测序（NGS）方法鉴定了低含量土壤（LS）和高含量土壤（HS）样本的真菌群落结构。随后，我们通过统计分析确定了这两组样本的真菌群落及组成差异。尽管组内不同样本间真菌群落和组成存在差异，但LS样本和HS样本的真菌组成情况如下。LS样本以 为主，而HS样本以 和 为主。LS样本中的主要物种是 和 ，而HS样本中的优势物种是 和 。这些结果表明，由于在马铃薯种植区施用FLC，LS样本和HS样本具有不同的根际土壤真菌群落及组成变化。
