specific Embodiment approach 1

[0015] Specific embodiment one: a kind of compound preparation that promotes the release of activated phosphorus from bottom sludge of freshwater aquaculture ponds according to the present embodiment is composed of 20-25 parts of phytase, 20-25 parts of soil phosphorus activator and 50-60 parts of kaolin.

[0016] The compound preparation of this embodiment acts on the bottom mud of the pond, can effectively convert the organic phosphorus in the bottom mud into active phosphate and release it into the overlying water for use by phytoplankton, and can effectively inhibit the release of ammoniacal nitrogen in the bottom mud , Improve the water quality environment. It can be used instead of phosphate fertilizer in the thinner aquaculture water body to achieve a good fertilizer and water effect, and at the same time, it can effectively improve the bottom quality of the pond.

[0017] The compound preparation of this embodiment can be widely used in freshwater aquaculture ponds wi...

specific Embodiment approach 2

[0018] Specific implementation mode two: the preparation method of a kind of composite preparation that promotes the release of active phosphorus in freshwater aquaculture pond bottom mud of the present embodiment is: take by weighing 20~25 parts of phytase, 20~25 parts of soil phosphorus activator and For 50-60 parts of kaolin, add the weighed components into a mixer, stir evenly, and then granulate with a granulator to obtain a compound preparation that promotes the release of active phosphorus from the bottom mud of freshwater aquaculture ponds.

[0019] The compound preparation of this embodiment acts on the bottom mud of the pond, can effectively convert the organic phosphorus in the bottom mud into active phosphate and release it into the overlying water for use by phytoplankton, and can effectively inhibit the release of ammoniacal nitrogen in the bottom mud , Improve the water quality environment. It can be used instead of phosphate fertilizer in the thinner aquacultur...

specific Embodiment approach 3

[0021] Embodiment 3: The difference between this embodiment and Embodiment 3 is that the unit of phytase activity is 5000 U / g. Others are the same as in the third embodiment.

Abstract

The invention relates to a composite preparation for promoting the release of active phosphorus in sediment of a freshwater aquiculture pond and a preparation method for the composite preparation, and relates to a composite preparation for promoting the release of active phosphorus in sediment of an aquiculture pond and a preparation method for the composite preparation. By the invention, the problems that phosphorus in water is deficient and the phosphorus in the sediment is high in content but cannot be released in the conventional aquiculture pond are solved. The composite preparation consists of phytase, a soil phosphorus activating agent and kaolin. The preparation method for the composite preparation comprises the following steps of: weighing the phytase, the soil phosphorus activating agent and the kaolin, adding the weighed components into a stirrer, stirring uniformly, and granulating by using a granulator. The composite preparation acts on the sediment of the pond, so that the water environment is improved effectively, and the environment of a substrate of the pond can be improved. The composite preparation can be widely applied to freshwater aquiculture ponds of which the organic matter content of the sediment is high, and also can be applied to aquiculture phases including water culture after the aquiculture ponds are cleaned.

Description

technical field [0001] The invention relates to a compound preparation for releasing active phosphorus from bottom mud of a breeding pond and a preparation method thereof. Background technique [0002] During the freshwater pond culture process, a large amount of organic matter such as residual bait and feces is deposited, resulting in the enrichment of nitrogen and phosphorus in the bottom mud of the pond, which in turn causes the deterioration of the bottom quality of the pond and seriously endangers the healthy growth of farmed animals. In a normal breeding environment, under the action of bacteria in the pond bottom mud, a large amount of toxic substance ammonia nitrogen is released, while the release of active phosphate is often inhibited. [0003] At present, in some specific breeding stages where the water body is thin, farmers usually apply exogenous phosphorus fertilizers to promote the reproduction of plankton to increase the fertility of the water body. Moreover,...
