将作物秸秆、人畜粪尿、杂草等各种有机物料,在密闭的沼气池内经嫌气发酵制取沼气后所剩残渣和肥液,即为沼气池肥。沼气池肥料的养分含量,主要决定于配料的比例、酸碱度、发酵温度、密闭程度、水分及沼气细菌的接种等因素。沼气池肥是矿质化和腐殖质化过程进行比较充分的肥料,它较一般有机肥料的利用率高得多,且具有速效、迟效养分兼备。腐殖质含量较高和富含激素、维生素类物质的特点。
The crop stalks, human and animal waste urine, weeds and other organic materials, in the closed biogas digester gas fermentation system after the residual gas and fertilizer, biogas pond fertilizer. Digester fertilizer nutrient content, mainly depends on the proportion of ingredients, pH, fermentation temperature, the degree of confinement, water and biogas bacteria inoculation and other factors. Biogas digester fertilizer mineralization and humification process more adequate fertilizer, which is more than the average utilization rate of organic fertilizer is much, and with quick-acting, delayed nutrient both. High humus content and rich in hormones, vitamin characteristics of the material.
