摘要:

为探究套作红薯对烟草根际土壤微生物多样性的影响,并为该种植模式的推广提供理论依据,本研究采用 Illumina MiSeq 高通量测序技术,比较了烟-薯套作与烟草净作2种处理下烟草根际土壤微生物的多样性及群落组成。结果表明,与烟草净作相比,烟-薯套作显著(p<0.05)降低了根际土壤真菌群落的α多样性。在细菌门水平上,烟-薯套作处理中酸杆菌门与厚壁菌门的相对丰度分别提高3.29和1.82百分点,而放线菌门、变形菌门和绿弯菌门则分别下降2.70、1.16和1.82百分点。在真菌门水平上,被孢霉门、担子菌门和unclassified_k_Fungi的相对丰度分别增加3.01、1.94和0.91百分点,子囊菌门则下降5.92百分点。在细菌属水平上,norank_f_Vicinamibacteraceae、norank_f_norank_o_Vicinamibacterales、芽孢杆菌属、RB41和norank_f_norank_o_Gaiellales的相对丰度在套作处理中分别提高0.67、0.86、1.47、0.67和0.15百分点;而norank_f_JG30-KF-CM45、norank_f_67-14、norank_f_Gemmatimonadaceae、norank_f_norank_o_norank_c_KD4-96、芽殖球菌属、链霉菌属和土壤红杆菌属则分别降低0.43、0.01、0.37、0.21、0.31、0.25和0.15百分点。相关分析表明,土壤pH值对根际微生物群落影响较大,对厚壁菌门、绿弯菌门、子囊菌门和被孢霉门均具有显著影响。本研究为烟-薯套作模式的推广与应用提供了理论支持。

Abstract:

To investigate the effects of intercropping sweet potato with tobacco on the tobacco rhizosphere soil microbial diversity and to provide a theoretical basis for the promotion of this cropping pattern, Illumina MiSeq high-throughput sequencing technology was employed to compare the microbial diversity and community composition in the tobacco rhizosphere soil under two treatments: tobacco-sweet potato intercropping and tobacco monoculture. The results showed that, compared with tobacco monoculture, intercropping with sweet potato reduced the α-diversity of the fungal community in the rhizosphere soil. At the bacterial phylum level, the relative abundances of Acidobacteriota and Firmicutes increased by 3.29 and 1.82 percentage points, respectively, under intercropping, while those of Actinobacteriota, Proteobacteria, and Chloroflexi decreased by 2.70, 1.16, and 1.82 percentage points, respectively. At the fungal phylum level, the relative abundances of Mortierellomycota, Basidiomycota, and unclassified_k_Fungi increased by 3.01, 1.94, and 0.91 percentage points, respectively, whereas that of Ascomycota decreased by 5.92 percentage points. At the bacterial genus level, the relative abundances of norank_f_Vicinamibacteraceae, norank_f_norank_o_Vicinamibacterales, Bacillus, RB41, and norank_f_norank_o_Gaiellales increased by 0.67, 0.86, 1.47, 0.67, and 0.15 percentage points, respectively, under intercropping. In contrast, the relative abundances of norank_f_JG30-KF-CM45, norank_f_67-14, norank_f_Gemmatimonadaceae, norank_f_norank_o_ norank_c_KD4-96, Blastococcus, Streptomyces, and Solirubrobacter decreased by 0.43, 0.01, 0.37, 0.21, 0.31, 0.25, and 0.15 percentage points, respectively. Correlation analysis indicated that soil pH value significantly influenced the rhizosphere microbial community, exerting notable effects on Firmicutes, Chloroflexi, Ascomycota, and Mortierellomycota. This study provides a theoretical foundation for the promotion and application of the tobacco-sweet potato intercropping pattern.
