摘要
草炭与硬杂木锯末以2．6:1比例混匀后,接种不同微生物发酵剂和喷施500倍木醋液,在温室里容积为2．5m3的发酵槽中进行对比试验,试验结果:喷施500倍木醋液比对照最高发酵温度高7℃,平均发酵温度高4℃;大于40℃以上中高发酵温度多7天;HA总比对照增加11．47％,HA游含量也略高于对照。在只接种微生物发酵剂的处理中,最高发酵温度是酵素菌56℃>高温纤维分解菌55℃>秸秆速腐剂54℃>EM53℃>对照46℃;在喷施木醋液条件下接种发酵剂,最高发酵温度是高温纤维分解菌57℃=酵素菌57℃>速腐剂50℃>EM48℃。HA总及HA游含量也是高温纤维分解菌+木醋液与酵素菌+木醋液两个处理明显高于对照及其他接种剂处理。
Peat and hardwood sawdust were mixed in a ratio of 2.6 to 1. The mixture in a 2.5 m^3 fermenting pool of the greenhouse was then inoculated with different microorganisms and sprayed with 500 fold wood vinegar dilute solution. The results showed that the wood vinegar solution increased fermentation temperature by 4 ℃ on average. The highest temperature in the wood vinegar treatment was 7 ℃ higher than that of the control. The duration at higher than 40 ℃ was 7 days longer than that of the control. Total HA content 11.47% higher than that of the control. Free HA content was also higher in the wood vinegar treatment. The highest temperatures of treatments inoculating fermenting, cellulosedecomposing, straw-decomposing and EM were 56 ℃, 55 ℃, 54 ℃and 53 ℃ respectively. But the control was only 46 ℃. Adding both microorganisms and wood vinegar dilute solution, the highest temperatures were 57 ℃ for both cellulose-decomposing and fermenting microbial treatments, 50 ℃ for straw-decomposing microorganisms and 48 ℃ for EM treatment. Both Total and free HA had similar changes
