沼液是有机物经厌氧发酵后的液态残留物,含有农作物生长发育所需的多种微量元素,特别是含有多种活性物,其中丁酸、吲哚乙酸、维生素B1 2等对病菌有明显的抑制作用。沼液中的氨盐和氨态氮、抗生素等对一些害虫有直接防治作用,因此,沼液是“广谱性的兼具生物农药和肥料特性的厌氧微生物加工物”。同时也是一种速、缓效互补的优质有机肥。但相对于沼渣等其它有机基肥,其肥效不高,因此,作为肥料仅就地利用才有价值,异地
Biogas slurry is a liquid residue after organic fermentation by anaerobic fermentation and contains various trace elements required for the growth and development of crops, in particular, a variety of active substances, of which butyric acid, indole acetic acid and vitamin B1 2 are obvious to the bacteria Inhibition. Biogas slurry in the ammonia and ammonia nitrogen, antibiotics and other pests have a direct role in the prevention and control, therefore, biogas slurry is “a broad spectrum of both biological pesticides and fertilizer characteristics of anaerobic microbial processing.” At the same time is also a fast, slow complement each other high-quality organic fertilizer. However, compared with biogas residue and other organic-based fertilizer, its fertilizer efficiency is not high, therefore, as a fertilizer only on-site use of value, off-site
