添加有机废弃物对茶渣高温堆肥过程中氮变化的影响

摘要

利用废弃茶渣为原料添加玉米杆、锯末、绿化废弃物和VT-1000微生物菌剂进行高温堆肥，采用人工翻堆方法，研究茶渣高温堆肥过程中总氮、铵态氮和硝态氮含量随时间的变化。结果表明：从堆肥的温度变化来看，添加玉米秆处理高温持续时间长且温度高，腐熟效果最好；从氮的变化情况看，茶渣堆肥过程中添加玉米杆、锯末和绿化废弃物有利于茶渣堆肥的腐熟进程，而添加玉米杆腐熟效果最好。%Using tea leaves residue as raw material by adding corn stalk, sawdust, green wastes and VT - 1000 microbial agents in high temperature compost with artificial pile method, to research total nitrogen, ammonium nitrogen and nitrate nitrogen contents change with time in high temperature compost. The results show that from the point of the temperature variation, adding corn stover by high temperaturein in long time, rotten effect is the best; from nitrogen variation aspect, adding corn stalk, sawdust and greening wastes are advantageous to the tea leaves residue composting rotten process, but adding the corn stalk rotten effect is the best.
