【摘要】：【目的】中药渣富含纤维素、作物生长所需的营养元素等,是制作有机肥料的重要来源之一,研究不同微生物菌剂对中药渣堆肥效果的影响,对合理地科学地利用中药渣有机肥的效果有重要意义。【方法】本文以藿香正气液、通天口服混合药液渣为研究对象,分别添加3种高纤维素腐熟速率的复合微生物菌剂(TSM、TEM、TSEM),采用条垛式堆肥系统进行堆肥试验,对比分析了不同微生物菌剂对中药渣堆肥效果,并进一步分析了堆肥过程中温室气体CO2和CH4的排放情况,为中药渣合理地利用提供科学依据。【结果】3种微生物菌剂处理的堆肥过程中温度经历升温期、高温期和降温期,其中TSM处理的高温期持续时间最长,达到了21 d。在整个堆肥周期内,中药渣堆肥的有机质含量表现为TSMTEMTSEM,至堆肥结束时,TSM、TEM、TSEM处理的中药渣堆肥的有机质为78.3%、76.9%和73.1%;仅TEM(T=(终点C/N比)/(初始C/N比)=0.520.6)和TSEM(T=0.480.6)处理的堆肥达到腐熟标准,但是仅TSEM处理的堆肥总养分含量(5.03%)和总金属含量达到中华人民共和国农业行业标准——有机肥料,且无毒性(GI=54%);同时在堆肥过程中,TSEM处理的CO2排放浓度最低(2.13×105~2.73×105mg·m-3),但是CH4排放量较高。【结论】在藿香正气液、通天口服液混合渣中接种TSEM微生物菌剂进行堆肥反应,实现了堆肥物料的资源化、减量化和无害化,但在实际生产过程中要注重温室气体CH4处理。
[Abstract]:[objective] the residue of Chinese medicine is rich in cellulose and nutritive elements needed for crop growth, which is one of the important sources of making organic fertilizer. The effect of different microbial agents on composting effect of Chinese medicine residue was studied. It is of great significance for the rational and scientific utilization of traditional Chinese medicine residue organic fertilizer. [methods] this paper takes Huoxiang Zhengqi liquid and Tongtian oral mixed liquid residue as the research object. The composting experiments were carried out by adding three kinds of compound microbial agents with high cellulose decay rate, TSM TTM TSM and TSEM, respectively. The composting effects of different microbial agents on Chinese medicine residue were compared and analyzed, and the composting effects of different microbial agents on the composting of Chinese medicine residue were compared and analyzed by using a stacking composting system. The emission of greenhouse gas CO2 and CH4 in composting process was further analyzed, which provided scientific basis for the rational utilization of Chinese medicine residue. [results] the temperature of compost treated with three kinds of microbial bacteria agents experienced temperature rise period, high temperature period and cooling period. The duration of high temperature period of TSM treatment was the longest, reaching 21 days. The organic matter content of Chinese traditional medicine residue compost is TSMTMTSEM, by the end of composting, the organic matter of traditional Chinese medicine residue compost treated by TSMSMTEMMA TSEM is 78.3% and 73.1%, only the compost treated with TEMN (initial C / N ratio 0.520.6) and TSEMN 0.480.6 meet the standard of decay, and the content of organic matter in the compost is 78.3% and 73.1% respectively, and the content of organic matter in the compost treated by TSM TMT TSEM is 78.3% and 73.1%, respectively. But only the total nutrient content of compost treated with TSEM is 5.03%) and the total metal content is up to the agricultural industry standard of the people's Republic of China-organic fertilizer. The CO2 emission concentration was the lowest 2.13 脳 10 ~ 5 ~ 2.73 脳 10 ~ (5) mg 路m ~ (-3), but the CH4 emission was higher. [conclusion] in the mixture of Huoxiang Zhengqi liquid and Tongtian oral liquid, TSEM microbial bacteria were inoculated to compost reaction. The compost material was reused, reduced and innocuous, but the greenhouse gas CH4 treatment should be paid attention to in the actual production process.
