【摘要】：为了解不同基质培育长裙竹荪栽培种覆土层土壤微生物群落功能多样性特点,运用Biolog-ECO技术,分析了以生橡胶木屑和熟橡胶木屑为基质的覆土层土壤微生物群落功能多样性。结果表明:覆土层土壤微生物平均吸光值(AWCD)总体变化趋势和对六大类碳源的利用情况均为生料组大于熟料组和对照组,且熟料组和对照组基本一致;生料组Mc Intosh指数与熟料组、对照组间显著差异,但3组之间的Shannon指数(H')、Simpson指数(D)和Pielou指数(E)的差异均不显著。熟料作为培育长裙竹荪栽培种的基质加入,既增强了覆土层土壤的通透性,又为长裙竹荪菌丝的生长繁殖提供了丰富的营养和良好的土壤微环境,更有利于长裙竹荪栽培种菌丝的生长和繁殖,对长裙竹荪栽培种的培育质量具有重要的作用。
[Abstract]:In order to understand the functional diversity of soil microbial communities in different substrates, Biolog-ECO technique was used to analyze the functional diversity of soil microbial communities in overlying soil with raw rubber sawdust and cooked rubber sawdust as the substrate. The results showed that the total trend of (AWCD) and the utilization of six kinds of carbon sources in the soil covered soil were larger than those in the clinker group and the control group, and the clinker group and the control group were basically the same. The Mc Intosh index of raw meal group was significantly different from that of clinker group and control group, but there was no significant difference in Shannon index (H '), Simpson index (D) and Pielou index (E) among the three groups. The addition of clinker as the substrate for cultivating the cultivated species of Phylophora lanceolata has not only enhanced the permeability of soil covered with soil, but also provided rich nutrition and good soil microenvironment for the growth and reproduction of mycelia of Phylophora lanceolata. It is more conducive to the growth and propagation of mycelia of the cultivated species of Phylophora longicolor, and plays an important role in the quality of cultivation of Phylophora lanceolata.
