| Abstract:The experimental setup included net Sophora alopecuroides stem powder(T1),Sophora alopecuroides stem powder+stem crude fiber degrading bacteria(T2),Sophora alopecuroides stem powder+organic fertilizer and crude fiber degrading bacteria(T3),Sophora alopecuroides stem powder+urea+cellulose fiber degrading bacteria(T4),Sophora alopecuroides stem powder+organic fertilizer urea+crude fiber degrading bacteria(T5). Taking T1 as control to study the change of related parameters of Sophora alopecuroides stalks substrate for fermentation.The results showed that growth rate of composting temperature of T3 and T5 treatment significantly were faster than that of the control,and could keep high temperature for a long time(> 50 ℃ for 10 d,> 55 ℃ for 6 d), and shorten the rotten time of the stalks of Sophora alopecuroides pile body at end of the fermentation,to contrast,total organic carbon mass fraction and C/N was reduced by 12.20% and 27.76% respectively,total nitrogen mass fraction increased by 19.24% and 21.49% respectively,and NO-3-N increased by 12.72% and 13.60% respectively,NH4+-N was reduced by 16.67% and 21.26%,respectively,it were significantly higher than that of control and other processing,and there was no significant difference between the two processing,and increased the content of total nitrogen in the process of the composting for ensuring the fertility after it was rotten. To sum up,adding organic fertilizer+urea+inoculated microbe and organic fertilizer+inoculated microbe treatment pile body had better effect on promoting stalks substrate of Sophora alopecuroides. |
