| 摘 要： | 通过对上坡、中坡、下坡和平坡油茶林地土壤养分、微生物数量和林分生长量的调查研究,得出如下结论:(1)上坡、中坡、下坡的土壤养分状况差别不大,没有形成显著性差异;上坡的土壤养分含量除全钾含量外,其它指标均显著高于平坡。(2)下坡的土壤微生物数量明显高于其它坡位,不同坡位的微生物数量从大到小为下坡>中坡>上坡>平坡。(3)上坡的生长量指标除结果数外,其它指标均显著高于平坡,与中坡、下坡未形成显著性差异。试验结论将为油茶的科学种植提供理论依据。

| Abstract: | The soil nutrients, microbe quantity and growth of Camellia oleifera forest land in upslope, midslope, downslope and flat slope have been studied. It showed that the soil nutrients of upslope＇s, midslope＇s and downslope＇s have little difference, and there were not significant differences between them; the soil nutrients of upslope＇ s were significantly higher than flat slope＇ s except the content of total K; the microbe quantity of downslope＇s were significantly higher than the other＇ s, and the order of microbe quantity from big to small was downslope 〉 midslope 〉upslope 〉flat slope; the growth indexes of upslope＇s were significantly higher than flat slope＇s except the fruit number, but there were not significant differences between upslope＇s and midslope＇s and downslope＇s. It provided theoretical basis for the scientific planting of C. oleifera. |
