【摘要】：为研究林下种植竹荪地竹荪采收后土壤微生物功能多样性,运用Biolog-ECO技术,分析了竹林地、橡胶林地和生姜竹荪套种地竹荪采收后的土壤微生物群落功能多样性。结果表明: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竹林下种植竹荪地(竹林地)橡胶林空白对照地橡胶林下种植竹荪地(橡胶林地)生姜+竹荪套种地(竹林地),即竹林地活性最强,套种地活性最低。土壤微生物Shananon-Wiener指数(H'值)、Pielou均匀度指数(E值)、Simpson指数(D值)的总体趋势均为竹林地橡胶林对照地橡胶林地生姜+竹荪套种地,即土壤微生物多样性竹林地最高,套种地最低。竹林地土壤微生物的Mc Intosh指数与橡胶林地、生姜+竹荪套种地和橡胶林对照地间差异均显著,且均极显著;橡胶林地和生姜+竹荪套种地土壤微生物的Mc Intosh指数差异不显著,但这两地的土壤微生物的Mc Intosh指数与橡胶林对照地差异均显著,且均极显著;不同样地土壤微生物的Shannon指数(H')、Simpson指数(D)和Pielou指数(E)差异均不显著。
[Abstract]:In order to study the functional diversity of soil microbial communities in bamboo plantations under the forest, the functional diversity of soil microbial communities of bamboo plantations, rubber forest land and interplanting land of ginger bamboo shoot were analyzed by Biolog-ECO technique.The results showed that the total variation trend of soil microbial average absorptivity value and the utilization of six major carbon sources were all planted under bamboo forest under bamboo forest (bamboo forest land) and under rubber forest blank control land (rubber forest) under rubber forest (rubber forest).The ginger bamboo shoot is planted in the field (bamboo forest land, that is, the bamboo forest land is the most active).The activity of interplanting land was the lowest.The general trend of soil microbial Shananon-Wiener index and Pielou evenness index (E) and Simpson index (D) were as follows: the interplanting land of Ginger bamboo shoot in rubber forest was the highest in soil microbial diversity and the lowest in interplanting land.The MC Intosh index of soil microorganism in bamboo forest land was significantly different from that in rubber forest land, interplanting land of ginger bamboo shoot and rubber forest, and there was no significant difference in MC Intosh index between rubber forest land and interplanting land of ginger bamboo shoot interplanting land, and there was no significant difference in MC Intosh index of soil microorganism between rubber forest land and ginger bamboo shoot interplanting land.However, the Mc Intosh index of soil microorganism in these two areas was significantly different from that of rubber forest, and the Shannon index and Pielou index of soil microorganism in different areas were not significantly different.
