Abstract
The invention relates to a fermented product composition for lowering levels of ammonia nitrogen and nitrite nitrogen in a prawn pool and a preparation method thereof. The method comprises the steps: 1) separately and uniformly mixing and stirring 60-80% of cassava starch, 10-20% of zeolite powder, 2-15% of EM (effective microorganism) stock solution and 5-10% of yucca extract; 2) mixing the mixed raw materials with water in a weight percentage of (1:5)-(1:7), and uniformly stirring; and 3) transferring the mixture of the mixed raw materials and pool water to a sealed container, and fermenting for 24 hours. The fermented product composition provided by the invention can supplement the nutritional requirements of the prawn, and simultaneously can significantly improve the carbon/nitrogen ratio in a water body of a prawn aquaculture pool at middle and later periods, thereby promoting the conversion of ammonia nitrogen and nitrite nitrogen in the water body and improving the health level of the prawn.
Description
Technical field
The present invention relates to a kind of preparation that can reduce ammonia nitrogen and nitrous acid nitrogen level in the water, belong to technical field of aquaculture, particularly relate to a kind of leavened prod composition and method of making the same that can reduce prawn pond ammonia nitrogen and nitrous acid nitrogen level.
Background technology
Prawn is China's culture fishery pillar kind, and developed recently is rapid, surpasses 5,000,000 mu, more than 100 ten thousand tons of output to cultured area in 2010.But shrimp culture industry also is faced with suitable serious plant disease crisis in fast development.Present stage, the prawn pond intensive culture of China adopted the breed structure of " unification of three pools " more.Cultivating pool is the metabolism pool of prawn, is again the pool of ingesting of prawn, also is the oxygenolysis pool of organism (meta-bolites of the prawn that breeding process produces, remaining feed, planktonic organism corpse etc.).Carry out along with culturing active, the organism that enters cultivating pool is more and more, substantially exceeds the self-purification capacity in pond, must cause the deterioration of breeding ecological environment, causes the generation of various diseases, hinders the normal growth of prawn.
Solve problems such as disease, environment, commodity prawn quality, at first should solve pond environment and repair problem, with the self-pollution that is produced in the breeding process, utilize ecological reestablishment to degrade, transform, make cultivating pool form benign ecological circulation system, thereby good, stable ecotope is provided.In the various environmental factorss that influence the prawn healthy aquaculture, culturing that middle and later periods water body ammonia nitrogen and nitrous acid nitrogen exceeds standard is the important factor that causes the prawn culturing failure.
Therefore, someone method by the water quality modifying microecological agent that comes into operation (Chinese patent application number be 200910027020.7) control water body ammonia nitrogen and nitrous acid nitrogen level, and also do not see with the method that reduces water body ammonia nitrogen and nitrous acid nitrogen level by certain leavened prod that in the pond, comes into operation.
Summary of the invention
The objective of the invention is to, a kind of leavened prod composition and method of making the same that reduces prawn pond ammonia nitrogen and nitrous acid nitrogen level is provided, in additional prawn nutritional need, can significantly improve the carbon-nitrogen ratio of prawn culturing pond middle and later periods water body, thereby the conversion of ammonia nitrogen and nitrous acid nitrogen in the promotion water body improves prawn health level.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of leavened prod composition that reduces prawn pond ammonia nitrogen and nitrous acid nitrogen level according to the present invention's proposition, its raw material mainly comprises the each component of following mass percentage content: tapioca (flour) 60～80%, zeolite powder 10～20%, EM stoste 2～18%, yucca extract 5～10%.
According to the leavened prod composition of the embodiment of the invention, be to make: tapioca (flour) 67%, zeolite powder 15%, EM stoste 8%, yucca extract 10% by the raw material of following mass percent.
In addition, the present invention also provides a kind of leavened prod preparation of compositions method that reduces prawn pond ammonia nitrogen and nitrous acid nitrogen level, comprises step:
1) with mass percent concentration is 60～80% tapioca (flour) respectively, 10～20% zeolite powder, 2～15% EM stoste, 5～10% yucca extract mixing and stirring;
2) with the above-mentioned raw materials that mixes and water according to 1: 5～1: 7 mixed of weight percent, stir;
3) mixture with mixing raw material and Chi Shui moves in the encloses container, and fermenting got final product after 24 hours.
According to the leavened prod preparation of compositions method of the embodiment of the invention, in the step 1), the mass percent concentration of described four parts of raw materials can also be: tapioca (flour) 67%, zeolite powder 15%, EM stoste 8%, yucca extract 10%.
By technique scheme, the present invention can reduce the advantage that the leavened prod composition and method of making the same of prawn pond ammonia nitrogen and nitrous acid nitrogen level has and be:
1) raw material is simple and easy to, and cost is lower;
2) configuration is simple, easy to use;
3) can effectively reduce water body harmful nitrogen level, reduce toxicity cultivated animals;
4) promote the microorganisms in water environmental balance, improve water body flora structure.
Embodiment
