Abstract:

In order to explore the effect of compound bio-fertilizer on native pasture improvement, five compound bio-fertilizers were fertilized which including control (CK), Humic acid fertilizer (F), Molasses fermentation fertilizer (T), Alginic acid fertilizer (H) and both three compound bio-fertilizer fertilizers (A),to study the effects on productivty,community characteristics and species diversity of Leymus chinensis mowing pasture in Horqin. The results showed that the community above-biomass of T was 27.18% which was higher than CK (P<0.05). The compound bio-fertilizer increased the community height, coverage and density. Treatment T increased the community height and coverage significantly (P<0.05), but the community density had no significant difference among the treatments. Treatment T, H and A increased the important value of Leymus chinensis, up to 20.46% increase in treatment T (P<0.05). The community Margalef diversity index, Shannon-Wiener diversity index, Pielou evenness index and Simpson dominance index had no significant changes. In conclusion, the compound bio-fertilizer improved the native pasture condition,and Molasses fermentation fertilizer (T) showed the best improvement effect in this study.

Key words: Compound bio-fertilizer, Mowing pasture, Productivity, Community diversity

摘要：

为了解复合微生物肥料在天然草场改良中的效果，本研究设置对照（CK）、腐殖酸（F）、糖蜜发酵（T）、海藻酸（H）和3种复合微生物肥料混合施入（A）5种处理，研究其对科尔沁羊草（Leymus chinensis）割草场草地生产力、植物群落特征和物种多样性的影响。结果表明：复合微生物肥料对天然草地的改良有一定促进作用。T处理地上生物量较CK显著增加了27.18%（P<0.05）；复合微生物肥料增加了群落高度、盖度和密度，T处理显著增加了群落高度和盖度（P<0.05），各处理间群落密度无显著差异；T、H和A处理增加了群落中羊草的重要值，其中T处理显著增加了20.46%（P<0.05）；群落Margalef丰富度指数、Shannon-Wiener多样性指数、Pielou均匀度指数和Simpson优势度指数都没有显著变化。综上所述，本研究选取的几种复合微生物肥料以糖蜜发酵（T）改良效果最佳。
