Soil Bacterial Community of Rubber Plantations of Different Ages of Stand: Composition and Diversity Study
To understand the soil bacterial composition and diversity of rubber plantations of different ages of stand, soil samples were collected with 5-point sampling method, and the composition, diversity, and seasonal changes of soil bacterial communities in forests of three ages of stand were measured by using high-throughput sequencing. Acidobacteria, Chloroflexi, Actinobacteria Firmicutes, Bacteroidetes showed significant differences, and Nitrospirae showed extremely significant differences. Acidbacteria, Actinobacteria, γ-Proteobacteria, and Sphingobactaiia showed significant differences, while Ktedonobacteria, OPB35_soil_group, and Bacilli showed extremely significant differences. norank_c__Acidobacteria, Variibacter, Candidatus_koribacter, norank_o__JG30-KF-AS9 showed significant differences, and norank_c__OPB35_soil_group and Acidibacter showed extremely significant differences. There was no significant difference in the Simpson index, Sobs index, Ace index and Shannon index among the soil bacterial communities of the forests of three ages of stand. The seasonal interpretation of the microbial community was 24.60%. In summary, Proteobacteria and Acidobacteria were the most abundant bacterial groups and there was no significant difference in the diversity index, and the season was an important factor affecting community structure and diversity of soil bacterial communities of rubber plantations.

运用传统培养法和高通量测序技术研究不同植茶年限（5年、10年、20年）茶树根际土壤细菌的多样性、结构和组成,并分析茶树土壤理化性质与细菌群落的相关性,为改善茶树的土壤和提高茶树产量提供参考。结果表明：两种方法均指出不同植茶年限下的根际细菌群落结构存在显著性差异,5年和10年茶树细菌多样性显著高于20年茶树细菌;培养法得出厚壁菌门（Firmicutes）和芽孢杆菌属（Bacillus）为优势门属,高通量测序技术得出酸杆菌门（Acidobacteria）、变形菌门（Proteobacteria）、拟杆菌门（Bacteroidetes）和Candidatus_Udaeobacter属为优势门属;总氮（TN）、总钾（TK）、总磷（TP）、pH是影响茶树细菌群落的关键理化因子;随着植茶年限增加,要采取措施防止土壤酸化,适当增施氮肥和磷肥。

土壤微生物在森林生态系统中起着重要作用。高通量测序方法的出现为进一步认识土壤微生物提供了契机。本文利用Illumina Miseq高通量测序技术对宝天曼森林土壤的细菌多样性进行了初步研究。结果显示: 在31个采样点内, 随着采样点增加, 检测出不同分类水平的土壤细菌类群也在增多, 当采样点达到31个时, 检测出的土壤细菌类群达到45门163纲319目495科785属和42,632个OTU; 31个土壤样品中所检测出的细菌类群平均有34.2门114.7纲215.2目323.7科446.6属5,924.7个OTU, 其中门、纲、目分类水平上的优势类群(所占比例)分别为变形菌门(Proteobacteria)(38.30%)、α-变形菌纲(α-Proteobacteria)(18.08%)、根瘤菌目(Rhizobiales)(10.62%)。这些初步研究结果表明在一定程度上宝天曼森林土壤有较高的细菌多样性水平, 为进一步认识森林土壤细菌多样性与植物多样性关系等奠定了基础。
