摘要
沼气工程可有效解决生猪规模养殖粪尿的污染问题。但沼气生产过程中产生的沼液、沼渣达不到直接排放的要求,很可能会造成二次污染。同时,沼液、沼渣中含有丰富的有机质、腐植酸、营养元素、氨基酸、维生素、酶等物质。为有效解决并利用诏安县大中型养猪场的沼液、沼渣,本研究利用诏安县发顺农牧有限公司水稻试验地,研究施用沼液对水稻产量的影响。结果表明,施用沼液可提高水稻产量,平均产量提高6.09%。本研究为进一步综合利用沼液、沼渣提供了前期的实践经验。
Biogas engineering can effectively solve the manure pollution caused by the scale pig farming.However,the biogas slurry that produced in the process of biogas production is not up to the requirements for direct discharge,and it is likely to cause secondary pollution.At the same time,biogas slurry contains organic matter,humic acid,nutrient elements,amino acids,vitamins,enzymes and other substances.In order to effectively utilize biogas slurry produced by large and medium scale pig farm in Zhaoan County,effect of biogas slurry on rice yield was studied.The results showed that application of biogas slurry could improve rice yield,and the average yield increased by 6.09%.The research provides preliminary experience for further comprehensive utilization of biogas slurry.
