ELEMENT COMPOSITION FOR AQUACULTURE AND USE METHOD THEREOF

Technical field

The invention belongs to the technical field of aguaculture and relates to an element composition for aquaculture and a using method thereof.

Background technology

Aquatic chemical fertilizers can be divided into ammonia fer- tilizer, phosphate fertilizer, potash fertilizer and calcium fer- tilizer according to their different chemical compositions, as well as various trace element inorganic fertilizers. Their main functions are to provide necessary nutrients for aquatic phyto- plankton and beneficial microorganisms, promote their growth, in- crease the amount of bait for filter-feeding aquatic animals, de- grade organic matter and improve the quality of aquaculture water.

O as to achieve the purpose of increasing production. Application of inorganic fertilizers usually results in greater zooplankton abundance due to increased primary productivity.

At present, most of the fertilizers used in aquaculture con- sider the proportion of conventional fertilizers such as nitrogen, phosphorus, potassium and calcium, mainly inorganic fertilizers and fermented organic fertilizers. In addition to aquaculture or- ganisms, the growth and reproduction of plankton, aquatic plants and microorganisms in aquaculture ponds require not only macroele- ments such as nitrogen, phosphorus, potassium and calcium, but al- so various trace elements for promoting physiological activities and growth and reproduction. When using fertilizers, some ferti- lizers can not be mixed, otherwise chemical reactions will occur in the water, such as: insoluble, reducing fertilizer efficiency.

And even that gas generate by the reaction deflagrates. Therefore, when multiple elements are mixed, this situation can not be ig- nored.

Summary of the invention

The invention aims at overcoming the defects and filling the blank of simultaneously supplementing a plurality of macroelements and trace elements in the aquaculture, thereby providing a solu- tion for solving the problem of insufficient supply of macroele- ments and trace elements in the aquaculture. The macroelement and microelement fertilizer for aquatic organism pond culture can in- crease the contents of macroelements and microelements with im- portant physiological and ecological functions in a pond, firstly, can meet the requirements of the macroelements and the microele- ments in aquatic organism culture, and can promote the reproduc- tion speed and the biomass of plankton in the pond, The ecological environment of the water area in the pond is more stable, the growth of harmful algae is inhibited, and the breeding risks of harmful algae tide, bad water and the like are reduced; The cul- tured object can directly absorb the nutrient elements from the pond water through organs such as gills, skin and the like, and the nutrient elements are supplemented into the body of the cul- tured object, so that the functions of promoting growth and devel- opment, enhancing immunity and the like are achieved; It also pro- vides a suitable carbon-nitrogen ratio for the growth of benefi- cial bacteria, in which inorganic substances and glucose are used as the nutritional components of beneficial bacteria to provide nutrition for the growth of beneficial bacteria, while zeolite powder provides adhesive for beneficial bacteria. In a word, the invention provides nutrition and a proper growth environment for beneficial algae and fungi, and meets the requirements of trace elements, calcium and the like for the growth of aquatic organ- isms.

The invention is realized by the following technical scheme:

The invention relates to an element composition for aquacul- ture, which comprises a first group of mixture and a second group of mixture, wherein the first group of mixture and the second group of mixtures are packaged separately and are mixed together only when in use, and the mass part ratio of the first group mix- ture is as follows: 95 to 100 parts of KH.PO,, 140 to 150 parts of

KCl, 50-100 parts of CaCl,, 0.5-1 part of FeSO,, 0.005-0.01 part of

Zn804, 0.1-0.3 part of MgSiOsand 0.05-0.1 part of MnCl,; 150 to 200 parts of NH4NO:, 60 to 80 parts of Mg; (POs),, 50 to 80 parts of CaCl;and 450 to 500 parts of MgSO, 0. 2-0.5 part of

FeCl;, 0. 2-0.6 part of ZnS0;, 15-20 part of H;BO,, 20-25 parts of glucose and 80-100 part of zeolite powder.

The invention also provides a using method of the mixture, which comprises the following steps of: respectively weighing the mixture according to the required amount, and then splashing one composition and then another composition in a water body, wherein the sequence of the two compositions is not required; and the spe- cific using amount and using method of the two compositions are as follows. :

Dosage and administration of the first group of mixture

Breeding density (tail/m) <50 2200

Use once every 10-15 days in 10-15 10-15 15-20 15-20 20-30 the early stage of seedling re- lease (kg/ha)

The cultivation period is 15-60 3-5 5-7 7-10 10-12 12-15 days, and the dosage is used every 7 days (kg/ha)

Use every 7 days from cultiva- 7-9 9-10 10-12 12-15 15-20 tion period 60 to harvest period (kg/ha)

Dosage and administration of the second group of mixture

Breeding density (tail/m) 50-100 | 100-150 150-200 | 2200 10-15 days in the early stage | 15-20 15-20 20-25 20-25 25-30 of seedling release, once used (kg/ha)

The cultivation period is 15- | 7-9 5-7 5-7 3-5 3-5 60 days, and the dosage is used every 7 days (kg/ha)

Use every 7 days from culti- | 5-7 5-7 3-5 3-5 2-3 vation period 60 to harvest period (kg/ha)

The macroelement and microelement fertilizers used in the culture process can improve the water quality environment of phy- toplankton, zooplankton and microorganisms living in the fish pond, promote the activities of the microorganisms, keep the sym- biotic relationship between the microorganisms and the zooplank- ton, improve the nutritional values of the phytoplankton, the mi- croorganisms and organic detritus, and strengthen the natural bait basis. O as to achieve the purpose of meeting the requirements of various macroelements and micronutrient elements such as N, P, K,

Ca, Mg, K, Si, Fe, Zn, Mn, B and the like needed by the growth and development of aquatic organisms. Aquatic organisms can not only obtain the nutrient elements from ingested feed, plankton, organic debris, bacterial aggregates and the like, but also directly ab- sorb the nutrient elements from pond water through gills, skin and the like, and supply the organs of the aquatic organisms, so that the metabolic process of the aquatic organisms is promoted, and the appetite of the aquacultural organisms for ingesting natural baits is more vigorous. Promotes the growth and development of aquatic organisms, has rapid growth, vigorous feeding, good health and bright body color, and achieves the purposes of improving the yield of aquatic organisms, improving the quality and saving feed.

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

The compositions of the present invention are packaged sepa- rately before the product is used due to the chemical reactions that occur when the components are mixed together.

In the intensive and high-density aquaculture ponds, it is not enough to supplement various elements only by feed and water body, and the transformation between various substances in water body is fast, the changes of total alkalinity, pH and total hard- ness indicate the loss of macroelements and trace elements, and the complete macroelements and trace elements will inevitably be- come limiting factors. Moreover, the unreasonable element composi- tion in the water and mud samples collected from aquaculture ponds has seriously affected the success rate of aquaculture, so regular exogenous supplementation is needed to promote algae reproduction, stabilize water quality and promote the normal growth of aquatic organisms. Under different pH and N/P control conditions, NH, NO,

KH, PO;, Mg (P0O1l0)), MgCl, MgSOand CaClwere added to the culture medium at different densities and in different environments.

Mg3i0, Feso 4, FeCl, HBOand other macroelements and trace elements are used as the addition amount of the fertilizer. The composition 5 of the invention provides a plurality of macroelements and micro- elements, promotes the shelling of the shrimps, has regular speci- fications and high growth speed, and can supplement minerals to balance the osmotic pressure of aquatic organisms and the minerals required by the stress shelling of the shrimps after rainstorm or overcast and rainy days. Relieve the shelling of aquatic organisms due to anoxic stress; promote the growth of algae and microorgan- isms ; Stabilize the algal and bacterial phase.
