The invention discloses a production method of a dual purpose microecological preparation for food (use) modification. On the one hand, the invention adopts the microbial fermentation method to increase the source and nutrition of the bait, adding algae to the kelp residue to make up the growth factor which is destroyed during the processing of the kelp residue, and produce the biologic microecological preparation by fermentation by the microorganism of the mixed strain. The product is rich in the production of the product. It contains all kinds of beneficial active microorganisms. With 50 algae 75% kelp residue as the main raw material, adding seaweed powder 10, 5 corn flour 10%, fish meal 1 5%, and shell powder 1 5%, the moisture content of the material was adjusted by fresh water or a certain amount of seawater, and the solid facultative fermentation of fresh water or a certain amount of seawater could be obtained by solid facultative fermentation. (good environment) biologic microecological preparation products, the product can be directly applied to the culture of the cucumbers. It can also be dried below 60 centigrade to less than 15% of water. After grinding up to 100 200 orders, the two use microecological agents are obtained. In the process of sea cucumber breeding, this product can significantly improve the survival rate and growth of the cucumbers, improve the water quality of the aquaculture water, reduce the occurrence of disease, improve the micro ecological balance of water body and improve the water quality of the aquaculture water, and have extensive popularization value.
【技术实现步骤摘要】
食(用)改(良环境)两用微生态制剂的生产方法
本专利技术涉及为生物发酵技术,提供了一种发酵型的既可饲喂刺参,又可改善刺参养殖环境,降低水体氨氮和亚硝态氮的生物制剂的生产方法。
技术介绍
随着刺参人工养殖产业的蓬勃发展,刺参消化生理和营养需求的研究也稳步发展,对刺参体内消化酶的研究促使刺参人工配合饵料的开发,在某种程度上促进了刺参育苗和养殖产业的发展,随后刺参发酵饵料开始出现,并表现出了较好的优越性。刺参肠道内含有众多的消化酶和微生物,有助于饲料的消化和吸收,即使如此,部分饵料仍消化吸收率仍较低。结合其他生物饵料的研究现状,刺参的发酵饵料应运而生。发酵饵料不仅可体外消化大分子、难降解物质,还可以补充大量的活性物质和消化酶,从而使刺参对营养物更易消化,使饵料更充分的利用,提高刺参整体的代谢水平,促进刺参的快速生长,这无疑将大大扩增刺参饵料的来源,促进刺参养殖业的发展。刺参发酵饵料中含有大量的活性微生物,其中乳酸菌类、芽孢菌类和酵母菌类,他们之间相互作用,不但能够提供消化酶增加刺参的消化功能,而且相互之间可以利用代谢物质,促进物质的转化,在发酵饲料过程中,发酵饵料的微生物在刺参肠道内,还是在刺参的排泄物中都含有大量的微生物,起到改善环境的作用,其中对含氮物质的转化尤为明显。海带渣是在海藻酸钠生产过程中得到的悬浮性固体组分,海带渣可作为饲料添加剂,其作为水产饲料的研究,现阶段也取得了一定的效果:海带渣完全可以应用于像刺参这类杂食性水产动物的饵料当中。发酵过的海带渣含有大量的活性微生物,这些微生物以海带渣为载体形成复合的菌群,在刺参消化道内,还是刺参的养殖环境中都起 ...
