| الوصف: | In order to better rot mushroom residue and improve the content of available phosphorus and humus in compost, a high cellulose degrading strain YD4 was selected from the waste mushroom residue. The cellulose degrading bacterium Trichoderma reevi DGW1, rhizosphere promoting bacterium Bacillus subtilis SL-44 and Pseudomonas Rs-198 were used to compound five kinds of microbial agent combination:SL-44+Rs-198+YD4, SL-44+Rs-198+DGW1、Rs-198+DGW1+YD4、SL-44+DGW1+YD4、SL-44+Rs-198+YD4+DGW1. Different combinations of bacteria were inoculated with 2% volume fraction and the mushroom residue compost was carried out. The results show that:Compared with the control group, 30 days after composting, the composting treatment inoculated SL-44+Rs-198+YD4+ DGW1 entered the rot stage as soon as 13 days, the lowest electrical conductivity of the pile was 1.37 mS·cm-1, and the lowest optical density ratio (E4/E6) of humic acid to fulvic acid was 6.11. The content of available phosphorus and the maximum degradation rate of organic matter are higher. Inoculant SL-44+Rs-198+YD4+ DGW1 promoted the formation of humus and improved the maturity and stability of compost. |
