摘要:
为探明不同年限茶园根际土壤真菌菌群结构及多样性的差别,采用MiSeq高通量测序方法分析了5年、10年、25年和40年茶园根际土壤真菌的菌落组成、Alpha多样性、Beta多样性和组间差异性。结果显示,随着茶园年限增大,根际土壤pH值显著性降低;而土壤养分含量呈现先增后减趋势,其中25年茶园最高。不同年限茶园根际土壤真菌群落α多样性无显著差异,β多样性则5年与10年茶园相近、而25年和40年茶园相似。5年和40年茶园土壤中的优势菌目存在明显差异,其中粪壳菌目占5年茶园总菌群的20.93%、糙孢孔目占40年茶园总菌群的14.97%。此外,不同年限茶园根际土壤中差异性显著的菌种主要分布在粪壳菌纲和银耳菌纲。结果表明,不同年限茶园根际土壤真菌物种组成丰富、结构差异明显;随着茶园年限的增加,茶树根际土壤肥力增加和真菌群落数量增加,有利于茶树生长代谢的真菌种群增多。
Abstract:
To explore differences in fungal structure and diversity in the rhizosphere soil of tea plants for different ages of tea garden, the composition of fungal communities, alpha diversity, beta diversity and group variability in the rhizosphere soil with an age of 5, 10, 25, and 40 year s old tea gardens were studied using the Miseq platformmodel (technique) . Results show that the pH of rhizosphere soil decreased with an age of tea garden, and soil nutrients increased with an age of tea garden and decreased for the case of 40 year s old tea garden. No significant difference in the fungal community alpha diversity was found in the rhizosphere soil of different ages of tea garden, whereas the structures of fungal community beta diversity in the rhizosphere soil of 5 and 10year s old tea garden were similar as well as the identical feature was observed in the rhizosphere soil of 25 and 40years old tea garden. The dominant fungi species was notable in the rhizosphere soil of 5 and 40 year s old tea garden. The Sordariales accounted for 20.93% in the 5 years old tea garden, and Trechisporales accounted for 14.97% in the 40 year old tea garden. In addition, the rhizosphere soil of the different ages of tea garden was mainly distributed in the Sordariales and Tremellomycetes species. Overall, fungal community in the rhizosphere soil of different ages of tea garden was abundant and had obvious differences in species structure. The rhizosphere soil fertility and the amount of fungal communities increased with the age tea garden ages, favoring the increasing in population of fungi that facilitates the growth and metabolism of tea plants.
