通过两次连续温室玉米盆栽试验, 研究了施用具有调节微生物功能的生物有机肥对土壤微生物数量与活性的影响, 并利用传统平板计数法与BIOLOG ECO方法相结合研究生物有机肥对土壤微生物生态的影响.结果表明, 与化肥相比, 施用生物有机肥可显著提高土壤微生物中3大菌群的数量; AWCD值及微生物对不同碳底物利用水平的测定结果表明, 施用生物有机肥可明显提高土壤微生物对碳源的利用率, 尤其土壤中的羧酸、胺类和其他类碳源等.表明生物有机肥的施用能增加土壤微生物利用碳源能力, 改善微生物营养条件, 使微生物保持较高活性, 提高土壤微生物多样性.

Microbial organic fertilizer (which is a typical functional fertilizer) was used in a corn pot culture under greenhouse condition to determine the effect of microbial organic fertilizer on soil microbial ecology via plate count and BIOLOG ECO methods. The study shows significantly enhancement in the number of soil microbes under microbial organic fertilizer compared with chemical fertilizer. AWCD values and carbon source utilization analyses show that microbial organic fertilizer noticeably increases carbon source utility by microbes, especially utility of carboxylic, amino acids, and miscellaneous carbon sources. More carbon source is used under microbial organic fertilizer application than under other treatments. Microbial organic fertilizer increases carbon source utilization, improves soil microbial nutrient level, and also increases soil microbial community activity and diversity.
