摘要:
为明确不同类型绿肥混播对青海地区土壤真菌群落结构的影响及其主要驱动因子,本研究设置箭筈豌豆和毛苕子混播(HV)、箭筈豌豆和青稞混播(HB)、箭筈豌豆和油菜混播(RS)和箭筈豌豆单播对照(CK)的比较试验,利用宏基因组测序技术,分析了不同类型绿肥混播对土壤基础理化性质、有机碳组分、真菌群落多样性及组成的影响。结果表明,与箭筈豌豆单播对照(CK)相比,箭筈豌豆和毛苕子混播处理土壤有机碳含量提高10.84%,箭筈豌豆和油菜混播处理土壤微生物量碳含量增加19.97%。箭筈豌豆和油菜混播处理的土壤真菌群落的丰富度(Chaol指数)和多样性(Simpson指数)比CK分别提高36.42%和11.59%。不同绿肥混播处理还能增加土壤真菌群落组成的丰富度,门水平下箭筈豌豆和青稞混播处理毛霉菌门和担子菌门真菌的相对丰度分别提高7.24%和113.09%,箭筈豌豆和油菜混播处理壶菌门真菌的相对丰度提高583.79%。土壤全碳含量和微生物量碳含量与土壤真菌群落结构显著相关,是影响土壤真菌群落结构和多样性的主要驱动因子。本研究结果表明绿肥混播比绿肥单播能更好地优化土壤环境和真菌群落结构。
Abstract:
In order to clarify the effects of mixed sowing of different types of green manure on soil fungal community structure and its main driving factors in Qinghai area, a comparative experiment of mixed sowing of common vetch and hairy vetch (HV), mixed sowing of common vetch and highland barley (HB), mixed sowing of common vetch and rape (RS) and single sowing control of common vetch (CK) was set up in this study. The effects of mixed sowing of different types of green manure on soil basic physical and chemical properties, organic carbon components, fungal community diversity and composition were analyzed by metagenomic sequencing technology. The results showed that compared with CK, the soil organic carbon content increased by 10.84% under HV treatment, and the soil microbial biomass carbon content increased by 19.97% under RS treatment. The richness (Chaol index) and diversity (Simpson index) of soil fungal communities in RS treatment were 36.42% and 11.59% higher than those in CK, respectively. The mixed sowing of different types of green manure could also increase the richness of soil fungal community composition. At the phylum level, the relative abundance of Mucoromycota and Basidiomycota in HB treatment increased by 7.24% and 113.09%, respectively. The relative abundance of Chytridiomycota in RS treatment increased by 583.79%. Soil total carbon content and microbial biomass carbon content were significantly correlated with soil fungal community structure, which were the main driving factors affecting soil fungal community structure and diversity. The results of this study showed that green manure mixed sowing could better optimize soil environment and fungal community structure than green manure monoculture.
