摘要: 为了研究有机肥发酵过程中各种微生物和有害生物的变化规律,笔者利用平板稀释法研究了有机肥有氧发酵过程中微生物和有害生物的变化,并建立数学模型,以期为自然条件下条垛型积制有机肥发酵技术的完善及发酵时间的确定提供理论依据。研究表明:真菌、霉菌数量与发酵时间呈一元三次多项式方程曲线,随着发酵时间的延长呈减少的趋势。细菌数量随发酵时间的延长呈“下降—上升—下降”的一元三次多项式方程曲线。大肠杆菌值与发酵时间呈一元三次多项式方程曲线,随着发酵时间的延长而持续提高。蛔虫卵死亡率与发酵时间呈一元二次多项式方程曲线,随着发酵时间的延长呈上升趋势,至110天左右达到最大值。在自然条件下,条垛型积制有机肥发酵时间宜掌握在100~120天之间。

Abstract: The paper aims to study the changes of microorganism and harmful biology in the process of organic fertilizer oxygen fermentation. The author used the plate dilution method and established a mathematical model, in order to provide a theoretical basis to determine the production technology and fermentation time for organic fertilizer fermentation under natural conditions of windrow type. The results showed that the number of fungi and mildew presented a three quadratic polynomial equation curve with the fermentation time, and decreased with the prolonging of the fermentation time. The number of bacteria presented a‘down-up-down’ three quadratic polynomial equation curve with the prolonging of the fermentation time. Escherichia coli value presented a three quadratic polynomial equation curve with the fermentation time, and increased with the prolonging of the fermentation time. Mortality of ascarid eggs presented a two quadratic polynomial equation curve with the fermentation time, and increased with the prolonging of the fermentation time, and reached the maximum around 110 days. Under natural conditions, fermentation time of windrow type organic fertilizer should be within 100-120 days.
