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. 本研究表明，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. （图4 表2 参36）
Abstract:
To explore differences in fungal community structure and diversity in the rhizosphere soil of tea plants in tea gardens among different ages, the composition, alpha diversity, beta diversity, and group variability of fungal communities in the rhizosphere soil of 5-, 10-, 25-, and 40-year-old tea gardens (Y5, Y20, Y25, Y20) were studied using the Miseq platform. Results showed that the pH of the rhizosphere soil decreased as the age of the tea garden increased, while the soil nutrient content increased with age, except that this began to decrease in the 40-year-old tea garden. No significant difference in the fungal community’s alpha diversity was found in the rhizosphere soil among different tea garden ages. The structure and beta diversity of the fungal community in the rhizosphere soil of the 5- and 10-year-old tea gardens were similar to each other, as were those of the 25- and 40-year-old tea gardens. Certain dominant fungal species were most notably abundant in the rhizosphere soil of 5- and 40-year-old tea gardens. The order Sordariales accounted for 20.93% of fungi in the 5-year-old tea garden, and species of Trechisporales accounted for 14.97% of those in the 40-year-old tea garden. In addition, the rhizosphere soil of the tea gardens of different ages mainly contained fungi distributed among the Sordariales and Tremellomycetes orders. Overall, the fungal community in the rhizosphere soil of tea gardens of different ages was abundant overall and showed obvious differences in community structure among ages. The rhizosphere soil fertility and the amount of species in the fungal community increased with the age of the tea garden, favoring the increases in the populations of fungi that facilitate the growth and metabolism of tea plants.
