Description

Special water quality and substrate modifier for sea intestine culture

[ technical field ] A method for producing a semiconductor device

The invention relates to the field of aquaculture, in particular to a special water quality and substrate modifier for sea intestine aquaculture.

[ background of the invention ]

The sea intestine is named as urechis unicinctus. The sea intestine belongs to the family of urechis unicinctus, and like other urechis organisms, exists in an environment with sand bottom or half muddy sand bottom between seaside tides. Urechis unicinctus is widely distributed in the sea, grows from the frigid zone to tropical sea, but only produces in Bohai Bay in China. Urechis unicinctus is mainly distributed in the eastern environment: in beaches or rock seams on coastal areas such as the tobacco tables, Qingdao, etc. Therefore, the Shandong Jiaodong area is the largest producing area of urechis unicinctus in China. The discovery of urechis unicinctus in the mansion sea area of Fujian has also been reported.

The sea intestine cultivation mode mainly comprises indoor factory cultivation, mudflat cultivation and pond cultivation, and the main cultivation areas are Shandong and Liaoning coastal areas. Because the life style of the sea intestines is special, the sea intestines need to stay under the sediment of the pond bottom or the mud flat and the feeding way mainly takes the filter feeding, a large amount of artificial baits need to be fed in the factory culture or pond culture process, but the feeding of the artificial baits inevitably causes a large amount of residual baits and excrement to be accumulated at the pond bottom, the deterioration of the bottom material and the water quality is caused, and harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide and the like are increased along with the accumulation. This has a very adverse effect on the normal growth of the marine intestines, and it is necessary to improve the water quality and the substrate for marine intestine cultivation.

[ summary of the invention ]

The invention aims to provide a special water quality and substrate modifier for sea intestine culture, which can ensure water quality and fundamentally solve the problem that nitrogen and phosphorus in substrate sludge and water exceed standards.

In order to solve the technical problems, the invention adopts the technical scheme that: a water quality and substrate modifying agent special for sea intestine cultivation is composed of the following components, by weight, 50-60 parts of zeolite powder, 5-10 parts of sodium percarbonate, 20-30 parts of composite bacillus powder, 1-10 parts of tartaric acid and 10-20 parts of sodium bicarbonate;

the preparation process of the modifying agent comprises the following steps: zeolite powder, sodium percarbonate, composite bacillus powder, tartaric acid and sodium bicarbonate with preset weight are uniformly mixed and then are made into particles by a dry method.

Compared with the prior art, the invention has the beneficial effects that:

the invention can utilize the oxidability of the sludge to carry out oxidation-reduction reaction with the bottom sludge, improve the oxidation-reduction potential of the bottom sludge, decompose the ammonia nitrogen and nitrite accumulated at the bottom of the pool and realize the effect of oxygenation. Therefore, the bottom modified product designed by the invention can be dissolved and sunk in the process that the particles sink to the bottom of the pool after entering water, most of the particles can still be remained after sinking to the bottom of the pool, and finally the dissolution is continuously completed at the bottom of the pool, so that the effective components are uniformly distributed in the water body and the bottom of the pool, and the zeolite powder in the effective components has the adsorption characteristic that a great amount of harmful substances in the water body and the bottom can be adsorbed and flocculated and then decomposed by the composite bacillus. Overcomes the defect that the prior bottom-modified product can only 'modify the bottom' but can not effectively modify the water quality at the same time, can effectively improve the utilization rate of the pond, prolong the effective service life of the pond, promote the growth of plankton in the water body, particularly unicellular algae, enrich the bait organisms of sea intestines and improve the economic benefit.

the water quality and substrate modifying agent special for sea intestine culture is prepared by the following preparation process: the method comprises the following steps: 60 parts of zeolite powder, 5 parts of sodium percarbonate, 25 parts of composite bacillus powder, 10 parts of tartaric acid and 20 parts of sodium bicarbonate are uniformly mixed and then are made into particles by a dry method, and the particle making technology is not essentially different from the prior art, so the details are omitted.

Wherein the content of the first and second substances,

zeolite powder: the zeolite powder has a unique cavity structure in the molecular structure, the fineness of the zeolite powder used in the invention reaches more than 200 meshes, and a large amount of toxic and harmful substances such as ammonia nitrogen, hydrogen sulfide and the like in water can be adsorbed.

Compounding bacillus powder: and (3) decomposing toxic and harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide and the like in water and at the bottom of the pool.

Tartaric acid: the disintegrant component existing as the bottom modified granule reacts with sodium bicarbonate to accelerate the dissolution of the granule.

Sodium bicarbonate: the disintegrant used as the bottom modification granule reacts with tartaric acid to accelerate the dissolution of the granule, and the sodium bicarbonate is favorable for the propagation and growth of unicellular algae in water body to indirectly provide bait for jellyfish.

Sodium percarbonate: as an oxygen increasing agent, oxygen is generated after the oxygen increasing agent is decomposed in water.

The granular modifier prepared in the above examples 1-3 was used in an amount of 500-1000 g/mu-m by directly throwing into a pond. The invention has the following function principle: the product slowly settles to the bottom of the pool after entering water, tartaric acid and sodium bicarbonate react firstly to accelerate the disintegration of the particles in the settling process, so that the effective components in the bottom-modified particles are released into the water body from the settling process, and finally the particles falling to the bottom of the pool are continuously dissolved, and the effective components in the bottom-modified particles are gradually covered on the bottom mud of the pool in the dissolving process. Oxygen generated by the dissolved sodium percarbonate is gradually dissolved in water, and the oxygen is added to the water body. The zeolite powder can adsorb a large amount of toxic and harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide and the like in a water body. After the composite bacillus powder enters water, the composite bacillus powder activates and decomposes toxic and harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide and the like in water and in bottom mud, which are adsorbed by zeolite powder, namely, the toxic and harmful substances in the water and at the bottom of the pond are adsorbed in the zeolite powder by utilizing the adsorption characteristic of the zeolite powder, and then the composite bacillus powder is decomposed, so that the effect of purifying the water quality and the bottom substances of the sea intestine culture pond is fundamentally realized, and particularly, the composite bacillus powder has a better decomposition effect on elements such as nitrogen, phosphorus and the like accumulated in the bottom substances of the sea intestine pond. After sodium percarbonate enters water, the sodium percarbonate reacts with the water to generate oxygen so as to increase the content of dissolved oxygen in the water body.

The invention overcomes the defect that the existing bottom-modified product can only 'modify the bottom' but can not effectively modify the water quality at the same time, can effectively improve the utilization rate of the pond, prolong the effective service life of the pond, promote the growth of plankton in the water body, particularly unicellular algae, enrich the food organisms of sea intestines and improve the economic benefit.

The foregoing is for the purpose of illustrating the invention only and various simple changes and modifications within the spirit of the invention made by those skilled in the art should fall within the scope of the invention.
