title: [Effects of two microbial agents on high temperature composting of passion fruit marc].
abstract: This paper studied the effects of microbial agents Faby (MF) and Rongfeng (MR) on the dynamic changes of temperature, C/N ratio, NH(4)+ -N and NO(3)- -N contents and compost quality in the composting process of passion fruit marc. The results showed that both MF and MR could accelerate the composting process. Compared with the control, these two agents extended the sustaining time of high temperature from 4 days to 11 and 12 days, promoted the decrease of C/N ratio, and the NO(3)- -N concentration increased by 58.0% and 64.2%, respectively. After the amendment of MF or MR, the total N, P and K contents, total porosity and water-holding porosity in the compost increased significantly, while the bulk density decreased. No significant difference was observed in the effects of MR and MF on the high temperature composting process of passionflower fruit marc, but MF was more beneficial to the improvement of compost quality.
