榕风对西番莲果渣高温堆肥过程中氮变化的影响*

 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NH^-₄-N和水溶性NO^-₃-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,NH⁺₄-N向NO^-₃-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NH^-₄-N向NO^-₃-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。

Effect of Microbial Strain Rongfeng on the Nitrogen Dynamic Changes in Passion Fruit Marc High-temperature Compost Process

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,water-soluble NH~ _4-N,water-soluble NO~-_3-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 NH~ _4-N to NO~-_3-N was found,in the compost with passion fruit marc 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 NH~ _4-N to NO~-_3-N,accelerate the compost process of passion fruit Marc.And improve the quantity of compost.
