| 摘 要： | 本研究以牛粪和小麦秸秆为堆肥原料,设置不同C/N处理组（分别为25/1、30/1、35/1）,通过添加外源菌剂（枯草芽孢杆菌、黑曲霉菌、细黄链霉菌）和酶制剂（纤维素酶和蛋白酶）进行好氧堆肥,研究其对进程中温度、有机质、全氮、全磷、全钾指标的影响。结果表明,不同C/N条件下添加菌酶制剂能够提高高温期的平均温度,各组温度均能够达到《粪便无害化卫生标准》(GB 7959—1987)要求;添加菌酶制剂可以有效地促进有机物的降解;对堆体的含氮量有明显的提升作用;使全磷、全钾的相对含量增加;通过对堆肥进程中各项指标变化特性的综合分析,C/N为35/1的C8组（添加枯草芽孢杆菌+黑曲霉菌+细黄链霉菌组）的堆肥效果最好。

| Abstract: | In this study, cow dung and wheat straw were used as composting raw materials, and different C/N treatment groups (25/1, 30/1 and 35/1) were set up. The effects of exogenous bacteria (Bacillus subtilis, Aspergillus niger and Streptomyces flavus) and enzyme preparations (cellulase and protease) on temperature, organic matter, total nitrogen, total phosphorus and total potassium in the process of aerobic composting were studied. The results showed that adding bacterial enzyme preparation under different C/N conditions could increase the average temperature in high temperature period, and the temperature of each group could meet the requirements of Hygienic Standard for Harmless Treatment of Feces (GB 7959—1987). The addition of bacterial enzyme preparation could effectively promote the degradation of organic matter, obviously improve the nitrogen content of the composting pile, and increase the relative content of total phosphorus and total potassium. Through the comprehensive analysis of the change characteristics of various indexes in the composting process, C8 group with C/N of 35/1 (adding Bacillus subtilis+ Aspergillus niger+ Streptomyces flavus) had the best composting effect. |
