【摘要】：木薯渣堆肥过程中,起始物料采用接种微生物菌剂与人工翻堆相结合的模式进行堆肥,经过多种生物和生物化学过程而被转化。通过两个实验处理测定了堆肥过程各阶段温度,纤维素酶、蛋白酶、淀粉酶的活性和淀粉、纤维素、半纤维素、木质素、NH+4-N、NO-3-N的含量,并进行了相关性分析。结果表明,接种菌剂可使堆体快速升温,且提高堆肥过程中的最高温度,延长了高温期的持续时间,达到堆肥无害化处理的目的;纤维素酶、蛋白酶和淀粉酶活性的最高值出现在堆肥的高温期。生物酶活性与堆肥有机组分的含量呈显著负相关,说明生物酶活性可以表征木薯渣堆肥中有机组分降解的状况,指示木薯渣堆肥的发酵腐熟进程。
[Abstract]:In the composting process of cassava dregs, the initial materials were compost by the combination of inoculation of microbial agents and artificial piling, and were transformed through a variety of biological and biochemical processes. The temperature, the activity of cellulase, protease, amylase and the contents of starch, cellulose, hemicellulose, lignin, NH _ 4-N _ (no _ 3-N) in composting process were determined by two experimental treatments, and the correlation analysis was carried out. The results showed that inoculation of bacteria could increase the temperature of compost rapidly, increase the maximum temperature in composting process, prolong the duration of high temperature period, and achieve the purpose of harmless composting treatment, cellulase, cellulase, The highest activity of protease and amylase appeared in the high temperature period of compost. There was a significant negative correlation between the bioenzyme activity and the content of organic components in compost, which indicated that the bioenzyme activity could characterize the degradation of compost components in cassava residue compost, indicating the fermentation process of cassava residue compost.
