摘要
应用聚合酶链式反应—变性梯度凝胶电泳(PCR-DGGE)研究了不同栽培时间三叶赤楠根际微生物多样性特征。结果表明:采用改进的蛋白酶K-CTAB法提取的三叶赤楠土壤DNA经PCR扩增的产物经DGGE检测后得到的电泳条带清晰且分离效果好,可以明显反映出三叶赤楠生长过程中土壤微生物多样性的变化。栽培时间对三叶赤楠根际微生物特征有很大影响:随着栽培时间增加,土壤微生物多样性增加,在第4年多样性指数达到最高值2.741,第8年时多样性指数降为1.378。不同栽培时间三叶赤楠根际微生物类群组成有所变化。根际微生物特征可以作为盆景换盆的一个指导因素,三叶赤楠盆景的换盆在其生长4~6年时进行可能最为合适,此时三叶赤楠根际微生物的多样性最为丰富,进行换盆会加快其根际微生态系统的建成。
