摘要
背景和目的施肥对亚热带森林演替过程中土壤微生物群落和功能的时间动态的影响尚不十分清楚。方法在中国亚热带森林幼龄期和成熟期的三个生长季中，利用Illumina Miseq测序技术和土壤多功能指数对土壤细菌和真菌群落以及土壤多功能指数进行了为期4年的氮磷添加试验。结果表明，施肥（2.5-4.5%）、林龄（2.1-2.5%）、季节（2.3-12.52%）和土壤变量（6.8-12.8%）解释了总真菌群落、嗜渍真菌群落、外生菌群落和病原真菌群落10-22.44%的变异。此外，施肥（2.5-3.8%）、林分（0.7-1.1%）、季节（2.2-2.7%）和土壤变量（5.3-6.6%）解释了总细菌群落、寡养细菌群落和共养细菌群落 8.1-9.9% 的变化。此外，幼林中氮肥和成熟林中磷肥对全缘真菌、嗜渍真菌和 EM 真菌群落组成的时间动态有影响，但对病原真菌和细菌群落的时间动态没有影响（嗜渍真菌除外）。此外，土壤多功能指数的时间动态在成熟林中受氮肥影响，在幼林中不受氮肥影响，在两个森林阶段均不受磷肥影响。然而，这些影响因森林演替阶段和施肥类型而异，这说明在评估养分添加对亚热带森林土壤微生物的影响时，需要同时考虑森林阶段和施肥类型。
Effect of nitrogen and phosphorus fertilization on the temporal dynamics of soil microbial community and multifunctionality in young and mature subtropical forests
Background and aims
The impact of fertilization on the temporal dynamics of soil microbial community and function along subtropical forest succession is not well understood. The study aims to explore how the seasonal changes in fungal and bacterial communities and multifunctionality respond to fertilization in two subtropical forest stages.
Methods
Here, we examined soil bacterial and fungal communities using Illumina Miseq sequencing and soil multifunctionality index in a 4-year experiment of nitrogen (N) and phosphorus (P) addition in three growth seasons in young and mature stages in a Chinese subtropical forest.
Results
Our results showed that 10-22.44% variation of total, saprotrophic, ectomycorrhizal (EM) and pathogenic fungal communities were explained by fertilization (2.5-4.5%), forest stage (2.1-2.5%), season (2.3-12.52%) and soil variables (6.8-12.8%). In addition, 8.1-9.9% variation of total, oligotrophic and copiotrophic bacterial communities were explained by fertilization (2.5-3.8%), forest stage (0.7-1.1%), season (2.2-2.7%) and soil variables (5.3-6.6%). Furthermore, the temporal dynamics of the community composition of total, saprotrophic, and EM fungi, but not pathogenic fungi and bacterial groups, were affected by N fertilization in the young forest and by P fertilization in the mature forest (except for saprotrophic fungi). Additionally, the temporal dynamics of soil multifunctionality index was affected by N fertilization in the mature forest, but not in the young forest, and not by P fertilization in either forest stage.
Conclusion
This study revealed that fertilization influenced the temporal dynamics of the soil fungal community and multifunctionality index, but not the bacterial community. However, these effects varied by forest successional stages and fertilization type, underscoring the need to consider both forest stage and fertilization when assessing the impacts of nutrient addition on soil microbes in subtropical forests.
期刊介绍：
Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
