| 摘 要： | 为分析土壤化学性质和微生物群落对冰糖橙(Citrus sinensis)果实品质的影响,本研究在土壤类型、海拔、农事管理和树龄(10 年以上)均相同的情况下,分析了高品质(H)和普通品质(N)橙子树根围土壤化学性质差异,以及土壤细菌和真菌群落多样性和结构组成差异,并探讨了土壤化学性质和微生物群落结构组成与橙子品质的关系。结果表明,H组橙子树根围土壤中全钾含量显著高于N组土壤,有效锰含量显著低于N组土壤;此外,H组0~20 cm土层土壤有机质、交换性钙、交换性镁的含量和20~30 cm土层全氮和全磷含量显著高于N组相应土层土壤。高通量测序分析发现,两组土壤中细菌和真菌群落多样性和结构并无显著差异,但部分细菌和真菌类群的相对丰度发生了变化:绿弯菌门(Chloroflexi)、蓝细菌门(Cyanobacteria)和纤线杆菌科(Ktedonobacteraceae)等细菌类群与丛赤壳科(Nectriaceae)、枝孢菌科(Cladosporiaceae)和葡萄穗霉科(Stachybotryaceae)等真菌类群在H组土壤中显著富集。通过PLS-PM对比分析土壤化学性质、微量元素和微生物群落对橙子品质的影响,发现土壤真菌和细菌群落对橙子品质影响较小;土壤化学性质(主要是全钾、全氮和有机质含量)和土壤微量元素(主要是交换性镁含量)对橙子品质具有较大的影响,土壤化学性质整体上表现为正效应,土壤微量元素整体上表现为负效应。本研究结果可为橙园土壤的合理施肥提供科学依据。

| Abstract: | In order to explore the effects of soil chemical property and microbial community on the fruit quality of Bingtang orange (Citrus sinensis), this study was conducted to analyze the chemical property, the diversity and structure of bacterial and fungal communities in the soil samples collected around the roots of high-quality (H) and normal-quality (N) orange trees. The above-mentioned two groups were under the same conditions the soil type, altitude, agricultural management, and tree age (over 10 years). Relationships among soil chemical property, soil trace element content, microbial community structure and orange quality were also discussed. Results showed that the total potassium content in the H group soil was significantly higher than that in N group soil, while the available manganese content was significantly lower than that in N group soil. In addition, the 0~20 cm soil layer of H group had significantly higher contents of organic matter, exchangeable calcium, and exchangeable magnesium than those in N group. The concentration of total nitrogen and total phosphorus in the 20~30 cm soil layer of H group was significantly higher than that in N group. Through high-throughput sequencing analysis, we found that there was no significant difference in the diversity and structure of microbial communities between the two groups. However, the relative abundance of some bacterial and fungal taxa had changed. Bacterial taxa such as Chloroflexi, Cyanobacteria and Ktedonobacteraceae and fungal taxa such as Nectriaceae, Cladosporiaceae and Stachybotryaceae were significantly enriched in the soil of H group. Through the PLS-PM comparative analysis of the effects of soil chemical property, trace elements and microbial communities on the quality of oranges, it was found that soil fungi and bacterial communities had little effect on orange quality. While soil chemical property (mainly total potassium, total nitrogen and organic matter content) and soil trace element (mainly exchangeable magnesium content) had greater influence on orange quality. Soil chemical property had a positive effect in general, but soil trace element had a negative effect on it. Results of this study provide scientific basis for appropriate fertilization in orange orchards. |
