摘要
研究了在西番莲果渣高温堆肥体系中,接种榕风和添加牛粪对西番莲果渣高温堆肥过程中温度、全氮(T-N)、水溶性NH4--N和水溶性NO3--N随时间变化规律的影响。结果表明,西番莲果渣单独堆肥,升温慢,高温分解阶段时间短,全氮(T-N)损失大,NH4+-N向NO3--N转化量少,不宜单独堆肥;在西番莲果渣中加入牛粪和榕风能缩短进入高温分解阶段的时间、增加高温分解持续时间,减少全氮(T-N)的损失,促进NH4--N向NO3--N的转化,加快西番莲果渣堆肥化进程,提高堆肥产品的品质。
The high-temperature compost with passion fruit marc as raw material was carried out to study the effect of microbial strain Rongfeng on the dynamic changes of temperature, total-N, watersoluble NH4^＋ -N, water-soluble NO3^- -N in compost processing. The results showed that a slower temperature increased, shorter high-temperature decomposing period,larger T-N loss and less, transforming from NH4^＋ -N N to NO3^- -N was found, in the compost with passion fruit mare only. Adding cow manure and microbial strain Rongfeng shorten the time of reaching high temperature, extend high temperature decomposing duration, reduce the T-N losing, enhance transforming NH4^＋ -N to NO3^- -N, accelerate the compost process of passion fruit Marc. And improve the quantity of compost.
