Abstract: In order to improve the fertilizer utilization effect of sisal residue, this paper conducted an experiment of adding microbial agent and lime to the sisal residue  and studied the maturation effect and mineral nutrient loss rate. The results showed that 125 d after composting, the compost smell of sisal residue treated with bacterial agent alone presented mud fragrant, and germination index of sisal residue fermentation broth was significantly increased by 4.1 times than that of the control, and the effect on nitrogen, phosphorus and potassium nutrient contents and loss rate of compost was not significantly different from that of the control. Adding lime alone also had deodorizing effect, and there was no remarkable influence on nitrogen and phosphorus nutrient contents and loss rate of compost. The compost mass loss rate and potassium loss rate were significantly reduced. But the compost germination index was lower, only 1%. When the microbial agent was mixed with low level lime（lime: sisal residue=1∶300）adding, the germination index of compost was significantly improved, being 2.3 times of that of the control. Meanwhile, the compost total potassium content was outstandingly increased, reaching 3.3  g·kg-1, 10% higher than that of the control. The compost mass loss rate and potassium loss rate were also significantly reduced. Therefore, the initial conclusion was that microorganism inoculants could be added alone as maturation agent to promote maturation of sisal residue. When it was added and mixed with low level lime, the maturation effect of sisal flax residue compost was the best, the microorganism inoculants was a most suitable maturation agent for sisal flax residue.
