一般来说,用稻草之类作培养料,制堆后由于微生物的分解,稻草腐烂变较,料堆逐渐下沉变实,堆中心通气不良,好氧微生物一旦耗尽了可利用的氧气,代谢活动即停止,而厌氧微生物的生长则加快,产生厌氧发酵。为了弥补料堆氧气不足,每隔3～4天要进行翻堆,需连续翻4～5次。即使这样,堆料中、下部要避免厌氧发酵仍很困难,且由于料堆表面干燥、温度低,表面的部分料不能较彻底地发酵。为此,科学家们找到了一种有效方法,即采用室内后发酵。但是,
In general, the use of straw or the like for the cultivation of materials, after the heap due to the decomposition of microorganisms, straw rotting change, gradually sinking material pile real, heap center poor ventilation, aerobic microorganisms once depleted the available oxygen, Metabolic activity is stopped, while the growth of anaerobic microorganisms is accelerated, resulting in anaerobic fermentation. In order to make up for the shortage of material oxygen, every 3 to 4 days to be turned over, need to turn 4 to 5 times in a row. Even so, it is still very difficult to avoid anaerobic fermentation in the middle and bottom of the stack, and due to the dry and low temperature of the stack, some of the surface material can not be more thoroughly fermented. To this end, scientists have found an effective way to use indoor post-fermentation. but,
