二丁与连翘药渣联合堆肥腐熟度评价

为了对不同比例的二丁与连翘药渣堆肥腐熟度进行评价,采用条垛式好氧堆肥方式,将二丁和连翘两种药渣按照5种不同的比例进行堆肥处理,通过分析堆肥过程中温度、pH、C/N和发芽指数等指标的变化规律,对堆肥腐熟度进行评价。结果表明:在试验处理条件下及堆肥周期内,单一药渣堆肥的两组处理未能完全腐熟,混合药渣堆肥的3组处理均已达到完全腐熟的标准,说明两种药渣混合后进行堆肥,可以有效促进堆肥的顺利进行,且二丁与连翘比例为2∶1(质量比)时发酵效果最好。3组混合药渣的发酵产物可以作为有机肥或土壤改良剂施用,也可以与化肥配合,制备成有机/无机配方肥。

Evaluation of composting maturity of erding and forsythia residue

The composting maturity of erding and forsythia residue under different ratio was studied in the study.The stacking aerobic composting method was used to compost the two kinds of drug medicinal(erding and forsythia)at five different proportions.Based on the analysis of the changing characteristic of temperature,pH,C/N ratio,germination index and other indexes during composting,the composting maturity was evaluated.The results showed that under the treatment conditions of the study and within the composting cycle,two groups of single medicinal residue composting were not completely decomposed.All the three groups of the mixed medicinal residue composting reached the standard of completely decomposing,indicating that the mixture of erding and forsythia could effectively promote the progress of composting.In addition,the fermentation effect was the best when the ratio of erding and forsythia was 2∶1(mass ratio).The fermentation products of the three groups of mixed residue could be used as organic fertilizer or soil improver,and they could be prepared into organic and inorganic formula fertilizer in combination with chemical fertilizer.
