- 摘要:
- 为了促进玉米秸秆快速腐解还田，使秸秆资源能够在田间得到高效利用，减少环境污染，对实验室保藏的纤维素降解菌和木质素降解菌进行组合，以筛选高效降解玉米秸秆的微生物菌系，并通过玉米秸秆失重率、木质纤维素降解率评价该微生物菌系对玉米秸秆的降解效果。结果表明:由蜡样芽孢杆菌（Bacillus cereus）、枯草芽孢杆菌（Bacillus subtilis）、出芽短梗霉（Aureobasidium pullulans）、少孢根霉（Rhizopus microsporus）、苏云金芽孢杆菌（Bacillus thuringiers）组成的复合菌系对玉米秸秆的降解效果最好，秸秆失重率为29.83%，纤维素降解率为56.14%、半纤维素降解率为47.98%、木质素降解率为42.18%。高效降解玉米秸秆复合菌系的筛选对解决秸秆还田，提高土壤肥力和作物产量具有重要的现实意义和经济意义，同时，也可解决环境污染，具有一定的社会和生态效益。
- Abstract:
- In order to promote maize stalks rapid decomposition,so that maize stalks resources can be efficient use in the field,study the straw decomposition effects of different composite microbial system.After degraded,take weight loss rate of maize straw and lignocellulose degradation rate as standards,evaluation the maize stalks degraded effects of different composite microbial system.Finally,optimized the fermentation conditions of composite microbial system which has best maize stalk degraded effect.The results showed that the composite microbial system which compose of Bacillus cereus,Bacillus subtilis,Aureobasidium pullulans,Rhizopus,Bacillus thuringiensishad higher maize stalks degraded effect.The maize stalks weight loss rate was 29.83%,the degradation rate of cellulose,hemicellulose and lignin were respectively 56.14%,47.98%,42.18%.Screening of high efficient degradation of maize straw composite microbial system have important practical significance and economic significance to solve the straw,improve soil fertility and crop yield; At the same time,it also solve the environmental pollution,have a certain social and ecological benefit.
