沼液是沼气池里有机物和水在产气过程中经厌气发酵所产生的液体。具有植物所需的丰富营养元素和大量微生物代谢产物。试验证明,用沼液浸泡稻种能提高秧苗素质和成苗率,增强抗寒能力,提高稻谷产量。
Biogas slurry is the liquid produced by anaerobic fermentation of organic matter and water in the biogas digester during gas production. Rich nutrients required by plants and a large number of microbial metabolites. Experiments show that soaking rice seedlings with biogas slurry can improve seedling quality and seedling rate, enhance the ability of cold, improve rice production.
