根据堆肥原理,影响发酵的主要因素是水份、通气、酸硷度和营养料。如果这几个因素处理得好,那末主持发酵作用的微生物,便会活跃地工作起来。在制作堆肥时,这几个因素当中,酸硷度问题不大,因为堆肥物料一般是中性,如果处理得好,在发酵过程中产生有机酸不多;且堆肥常用粪便补充氮素,粪便有一定的中和有机酸的作用,因此自然就近乎中性,即使有微量的酸度,也没有大影响。营养料问题也不严重,农民用作堆肥的原料,绝大部分是稻麦藁桿、杂草和一些人畜粪便,这些 According to the principle of compost, the main factors affecting the fermentation are water, aeration, pH and nutrients. If these factors are handled well, then the microorganisms that host the fermentation will work actively. Among the several factors that make up the compost, acidity and alkalinity are not a problem because composting materials are generally neutral. If handled well, there are not many organic acids in the fermentation process. In addition, manure is commonly replenished with nitrogen and manure There is a certain role in the neutralization of organic acids, so naturally almost neutral, even with a trace amount of acidity, there is no big impact. Nourishment material problem is not serious, farmers used as compost raw materials, the vast majority of rice noodles, weeds and some human and animal feces, these
