Abstract:

【Objective】 To evaluate the effects of different microbial treatments on tomato soil microbial diversity, and provide theoretical basis and reference for improving soil microbial diversity and increasing tomato yield.【Methods】 With fruit tomato Nongbo powder 18109 as the test material, high-throughput sequencing technology was used to study the effects of microbial bacteria on tomato soil microbial diversity and environmental relevance of one control (CK) treatment and three microbial bacteria treatments of Actinomycetes (T1), Bacillus subtilis (T2) and Trichoderma harzianum (T3).【Results】 T3 had the highest bacterial content, T1 had the highest fungal content.The ratio of bacteria to fungi in T1 and T3 was greater than that of the CK, and soil microorganisms presented "bacterialization".Alpha diversity showed that T1 and T3 had more bacterial species than CK.T1, T2, and T3 have fewer fungal species than CK.Shannon and Simpson indexes of bacteria treated with T2 were lower than those of CK, and the Shannon and Simpson indexes of bacteria treated with T1 and T3 were lower.The Shannon and Simpson indexes of the fungi treated by the three microorganisms were higher than that of CK.There were differences among the four treatments of control, Actinomycetes, Bacillus subtilis, and Trichoderma harzianum, and there was a strong consistency among the same treatments.The bacterial and fungal diversity of T1 and T3 microbial treatments were similar.Among the bacteria, Unspecified_iii1_15,Unspecified_RB41, Unspecified_Gemm_5, Unspecified_Syntrophobacteraceae, Kaistobacter were the dominant bacterial genera.The relative abundance of Kastobacter in CK, T1, and T3 was the highest, and in T2 the relative abundance of Bacillus was the highest.Among the fungi, Fusarium, Unspecified_Chaetomiaceae, Unspecified_Pezizales, Unspecified_Hypocreales_fam_Incertae_sedis, Mortierella were the dominant fungi, the relative abundance of Fusarium was the highest among the 4 different treatments.The correlation between leaf width and microbial community distribution in bacteria and fungi was the smallest, and the correlation between leaf length, plant height, stem thickness, yield and microbial community distribution was high.The effect of Actinomycetes and Trichoderma harzianum on tomato soil microorganisms was relatively strong.The correlation between leaf length, leaf width, stem thickness and Actinomycetes was the strongest, and the correlation between yield and Trichoderma harzianum was the strongest.【Conclusion】 Different microbial treatments have different effects on tomato soil microbial diversity, but Actinomycetes and Trichoderma harzianum havw relatively greater effects on tomato soil microorganisms, and leaf length, leaf width and stem diameter have the highest correlation with Actinomycetes, Trichoderma harzianum has the highest correlation with yield.

摘要:

【目的】评估不同微生物菌处理对番茄土壤微生物多样性的影响,为改善土壤微生物多样性、增加番茄产量提供理论依据与参考。【方法】以水果型番茄农博粉18109为试材,采用高通量测序技术,研究放线菌(T1)、枯草芽孢杆菌(T2)、哈茨木霉菌(T3)3种微生物菌处理,以不施用微生物菌对照(CK)进行番茄土壤微生物多样性及与环境相关性的影响。【结果】哈茨木霉(T3)处理的土壤中细菌含量最高,放线菌(T1)处理的土壤中真菌含量最高,T1、T3的细菌和真菌的比例均大于对照,土壤微生物呈现“细菌化”。Alpha多样性显示T1和T3的细菌种类多于CK,T1、T2、T3的真菌种类均少于CK;T2处理的细菌Shannon和Simpson指数均低于CK,T1和T3处理的细菌Shannon和Simpson指数均高于CK,3种微生物菌处理的真菌Shannon和Simpson指数均高于CK。对照、放线菌、枯草芽孢杆菌、哈茨木霉4个处理间存在差异,相同处理间存在较强的一致性。T1和T3微生物菌处理的细菌和真菌多样性较为相似。细菌中Unspecified_iii1_15、Unspecified_RB41、Unspecified_Gemm_5、Unspecified_SyntrophobacteraceaeKaistobacter为优势细菌属。真菌中Fusarium(镰刀菌属)、Unspecified_Chaetomiaceae(未分类毛壳菌科)、Unspecified_PezizalesUnspecified_Hypocreales_fam_Incertae_sedisMortierella(被孢霉属)为优势真菌属,镰刀菌属(Fusarium)在4个不同处理中相对丰度最高。细菌和真菌中叶宽与微生物群落分布间的相关性均最小,叶长、株高、茎粗和产量与微生物群落分布间的相关性高;放线菌和哈茨木霉对番茄土壤微生物的影响相对较大,叶长、叶宽、茎粗与放线菌的相关性最高,产量与哈茨木霉的相关性最高。【结论】不同微生物菌处理对番茄土壤微生物多样性影响不同,但放线菌和哈茨木霉对番茄土壤微生物的影响相对较大,叶长、叶宽、茎粗与放线菌的相关性最高,哈茨木霉与产量的相关性最高。
