[目的]研究微生物复合菌剂在生猪发酵床中的效果。[方法]采用室内模拟发酵的方法,通过分析微生物发酵与自然发酵过程中温度、pH、硝化氮、铵化氮、脲酶酶活、蛋白酶酶活的变化,探讨复合微生物菌剂的填入对生猪发酵床的影响。[结果]与自然发酵的对照组相比,接种菌剂能促进发酵升温,并延长高温持续的时间,其温度升至60℃高温并维持了10d;接种菌剂能降低垫料环境pH,其最终pH值为7.05低于对照组的7.81;接种菌剂能促进铵态氮向硝态氮的转化,减少氮的损失;接种菌剂后,垫料中脲酶和蛋白酶的活性得到提高,加速了生猪排泄物的降解。[结论]该研究为生猪发酵床菌种开发、筛选及效果评价提供了技术参考。

[Objective] The aim was to study the effects of compound microbial inoculants on fermentation bed.[Method] With fermentation simulated in lab,analysis was conducted on changes of temperature,pH,nitrate nitrogen,ammonium nitrogen,urease activity and protease activity in fermentation by microorganism and natural fermentation respectively,to explore effects of compound microbial inoculants on fermentation bed of swine.[Result] Compared with control group,the added microbial inoculants in test group promoted temperature rising during fermentation and prolonged lasting period of high temperature,for example,high temperature at 60 ℃ maintained 10 d in the test.Furthermore,the inoculants reduced pH of packaging material environment,for example,pH finally was 7.05,lower than that of control group.Microbial inoculants accelerated transformation of ammonium nitrogen into nitrate nitrogen and reduced nitrogen loss.In addition,activities of urease and protease enhanced in packaging materials and excrements degraded rapidly.[Conclusion] The research provides technical references for strain development,selection and evaluation of fermentation bed of swine.
