以桉树皮为材料,通过添加不同氮源和微生物菌剂进行基质化腐熟处理,研究不同处理桉树皮腐熟过程中理化性质的变化.结果表明:添加有机氮源比无机氮源的处理升温快,能更好的促进腐熟进程;随着腐熟的进行,各处理的容重略有增加,孔隙性呈减小趋势,通透性得到改善;pH值呈增大趋势,EC值、CEC值和C/N值呈减小趋势,桉树皮基质缓冲协调性能得到改良;氮源和菌剂对腐熟各指标影响差异均显著,添加鸡粪和酵素菌剂的处理对腐熟效果较好,可作为桉树皮腐熟理想的添加氮源和菌剂.

@@@@In order to understand changes in the physical and chemical properties of Eucalyptus bark during the composting process , variations in the process due to adding different nitrogen sources and microbial agents were studied . The results showed that temperatures following addition of nitrogen in organic forms rose faster than following addition of inorganic forms of nitrogen .Also ,it was found that organic nitrogen sources promot-ed completion of composting process faster than inorganic sources .As composting neared completion ,the densi-ty of each treatment increased slightly and the porosity decreased , whilst permeability was moderated . Also , pH values of each treatment increased whilst EC values , CEC values and C/N ratios decreased . The form of nitrogen and type of microbial agent added were also found to have significant influences on the maturity in-dex . Treatments involving addition of chicken manure and ferment bacteria led to better maturity effect than other treatments . It was concluded that chicken manure and ferment bacteria could be used as ideal additives Eucalyptus
