以牛粪、菌糠和鸡粪等为材料按照两种比例调配为混合基质,在添加或不添加快腐剂的条件下在发酵桶中进行为期38 d的堆肥发酵实验,通过对发酵产物的温度、p H值、总有机碳、C/N、硝铵态氮含量和种子发芽指数等指标变化的研究,揭示了快腐剂对发酵过程的影响。结果表明,虽然快腐剂对有机物料的温度、C/N比无显著的影响,但可以促进铵态氮向硝态氮的转化,在16 d时使发酵产物NH+4-N/NO-3-N比值降为0.15,达到腐熟标准(0.16);提升种子发芽指数,在腐解29 d时使种子发芽指数达到82.76%,达到完全腐熟指标(0.8),比不添加快腐剂的处理提前了4 d左右。快腐剂的作用效果受腐解物料配比的影响。
With cow manure, bran and chicken manure as the material in two proportions formulated as a mixed matrix, with or without the addition of fast preservative conditions in the fermenter for 38 days of composting fermentation experiments, the fermentation product Temperature, p H value, total organic carbon, C / N, ammonium nitrogen content and seed germination index and other indicators of changes, revealing the effect of the fast preservative on the fermentation process. The results showed that although the preservative had no significant effect on the temperature and C / N ratio of organic materials, it could promote the conversion of ammonium nitrogen to nitrate nitrogen, and at 16 days, the fermentation product NH + 4-N / NO- 3-N ratio was reduced to 0.15, reached the maturity standard (0.16); seed germination index increased, the decomposition time of 29 d germination index reached 82.76%, to complete maturity index (0.8) About 4 days earlier. The effect of the preservative is affected by the ratio of decomposed material.
