摘要:

土壤微生物群落变化是影响连作障碍的主要因素之一。本研究以长兴县设施番茄种植区为研究对象,采用Illumina MiSeq技术,探究水稻-番茄轮作(D处理)、番茄连作+微生物菌剂处理(M处理)、番茄连作(N处理)等不同种植方式对根际土壤微生物群落的影响。结果表明,与N处理相比,D处理和M处理可改变根际土壤微生物群落结构,但对微生物的丰富度和多样性均未产生显著影响。D、M和N处理的番茄根际土壤微生物群落结构相似,但在门和属水平上的相对丰度存在显著差异。门水平的相对丰度差异主要出现在D处理与M处理、D处理与N处理之间,而M处理与N处理在细菌群落组成与丰度上较为相似;属水平的相对丰度差异主要出现在D处理与M处理之间,部分出现在D处理与N处理之间。D处理与M处理均能显著降低土壤有机质、全氮和有效磷含量;D处理可降低交换性钙含量并提高交换性镁含量,而M处理则使交换性钙和交换性镁含量均显著降低。土壤养分对细菌群落结构的影响大于对真菌群落的影响。综上,水稻-番茄轮作是影响番茄根际土壤微生物群落结构的主要因素,而微生物菌剂处理对真菌群落结构有一定影响,上述措施有助于缓解番茄种植土壤的盐渍化与连作障碍问题。

Abstract:

Changes in soil microbial communities are one of the main factors affecting continuous cropping obstacles. This study, focusing on the protected tomato (Solanum lycopersicum L.) cultivation area in Changxing County, used Illumina MiSeq technology to investigate the effects of different cropping systems—rice-tomato rotation (D treatment), continuous tomato cropping with microbial agent application (M treatment), and continuous tomato cropping (N treatment) on the rhizosphere soil microbial community. The results showed that compared with the N treatment, both D and M treatments altered the rhizosphere soil microbial community structure, but did not significantly affect microbial richness or diversity. The microbial community structures in the rhizosphere soil of tomatoes under D, M, and N treatments were similar, but significant differences existed in relative abundances at the phylum and genus levels. Differences in relative abundance at the phylum level mainly occurred between D and M treatments and between D and N treatments, whereas the bacterial community composition and abundance were relatively similar between M and N treatments. Differences in relative abundance at the genus level primarily appeared between D and M treatments, with some differences also observed between D and N treatments. Both D and M treatments significantly reduced soil organic matter, total nitrogen, and available phosphorus contents. The D treatment decreased exchangeable calcium content and increased exchangeable magnesium content, while the M treatment significantly reduced both exchangeable calcium and exchangeable magnesium contents. Soil nutrients had a greater influence on bacterial community structure than on fungal community structure. In conclusion, rice-tomato rotation is the primary factor influencing the rhizosphere soil microbial community structure in tomatoes, while microbial agent application has a certain effect on the fungal community structure. These measures contribute to alleviating soil salinization and continuous cropping obstacles in tomato cultivation.
