摘　　要：该试验在内蒙古半干旱区的科尔沁天然打草场开展。羊草是科尔沁区天然打草场的优势物种,近年来发生的不同程度的草场退化现象,严重影响了种群特征和群落生产力,尤其是地下生产力直接关系着牧草的产量和品质。本研究选取腐殖酸、糖蜜发酵物和海藻酸等3种复合微生物肥料,设置对照、单独施加该3种复合微生物肥料和混合施加等5个处理,分别表示为CK、F、T、H和A。结果表明,施加复合微生物肥料的年份、土层深度以及施加年份和复合微生物肥料种类的交互作用对群落地下生物量均有显著影响(P 0.05)。由此看出,单一复合微生物肥料对群落地下生物量变化没有显著的影响效果。The experiment was set in Horqin native grassland in Inner Mongolia semi-arid area. Leymus chinensis is the dominant species. Recent years, the grassland showed various degradations which had a strong impact on population characteristics and community productivity;above all, underground biomass was related to grass yield and quality. The Humic acid, Molasses fermen-tation and Alginic acid were selected in this study. And control, apply above three compound bio-fertilizers solely and mixed were set to be five treatments, and were indicated as CK, F, T, H and A. The results showed that the applying year, soil depth and the interaction of applying year and variety of compound bio-fertilizers had significant effects on community underground bio-mass (P 0.05). Thus it showed that the compound bio-fertilizers applied simply had no significant impact effect on community underground biomass.
