绿色水产养殖准则:不用或少用化肥、鱼药及其它化学物质,投入的饵料应能促进鱼类的生长、提高品质,不造成鱼类产生和积累有害物质,对生态环境无不良影响。实践表明,沼肥作为一种生物肥料,营养价值能完全满足藻类和其他微生物生长繁殖需要,又具有生物农药特性,能有效降低病害的发生率,为鱼类营造良好的生态环境,保障正常生长和摄食,降低饵料系数。文章在简要阐述沼肥主要组成与特性的基础上,详述了其应用技术。 Green aquaculture guidelines: No or less fertilizers, fish drugs and other chemicals, feed should be able to promote the growth of fish, improve quality, does not cause fish to produce and accumulate harmful substances, no adverse impact on the ecological environment. Practice shows that biogas fertilizer as a biological fertilizer, nutritional value can fully meet the growth and reproduction of algae and other microorganisms, but also has the characteristics of biological pesticides, can effectively reduce the incidence of diseases, for the fish to create a good ecological environment, to protect the normal growth And feeding, reduce the feed coefficient. Based on the brief description of the main composition and characteristics of biogas fertilizer, the article details its application technology.
