preparation example Construction

[0018] The preparation method of the water body nutrient used for the cultivation of Penaeus vannamei of the present invention comprises the following steps:

[0019] 1) Dry the shells in the sun, crush the shells into pieces with a crusher, then calcine them in a high-temperature furnace at high temperature, cool them naturally, and weather them into powder;

[0020] 2) Take the powder prepared in step 1), add trace element compounds in proportion, and mix evenly, which is the nutrient solid;

[0021] 3) The nutrient solids: sugarcane molasses: tap water are mixed evenly in proportion, put into a container and sealed for fermentation, and after fermentation, the water body nutrients suitable for the culture of Penaeus vannamei will be obtained.

[0022] In the step 1) the shell is selected from any one of oyster shells and pearl oysters. The preferred shell is oyster shell.

[0023] Said step 1) the broken shell size is 2-5 cm.

[0024] The step 1) the high temperature fur...

Embodiment 1

[0039] In the preparation method of the present invention, oyster shells are purchased, and the oyster shells are exposed to light for 72 hours outdoors. Then the dried oyster shells are preliminarily crushed with an iron hammer, put into a pulverizer and crushed, and sieved to pick out fragments of more than 2 cm for use.

[0040] Take 5 kg of oyster shell fragments, put them into the muffle furnace, close the door of the muffle furnace, adjust the temperature of the muffle furnace to 400 degrees and start the machine for 2 hours. After no smoke comes out, adjust the temperature to 800 degrees and continue to calcine for 3 After 2 hours, turn off the power, open the muffle furnace door to leave a gap in the door to dissipate heat, and fully open the muffle furnace door to cool after 2 hours.

[0041] The calcined pieces of oyster shells are taken out from the muffle furnace, spread flat on the clean ground and naturally weathered, turned during the process, and become powder ...

Embodiment 2

[0046] In the preparation method of the present invention, oyster shells are purchased, and the oyster shells are exposed to light for 72 hours outdoors. Then the dried oyster shells are preliminarily crushed with an iron hammer, put into a pulverizer and crushed, and sieved to pick out fragments of more than 3 cm for use.

[0047] Take 5 kg of oyster shell fragments, put them into the muffle furnace, close the door of the muffle furnace, adjust the temperature of the muffle furnace to 500 degrees and start the machine for 1 hour. After no smoke comes out, adjust the temperature to 800 degrees and continue calcination for 2 After 2 hours, turn off the power, open the muffle furnace door to leave a gap in the door to dissipate heat, and fully open the muffle furnace door to cool after 2 hours.

[0048] The calcined pieces of oyster shells are taken out from the muffle furnace, spread flat on the clean ground and naturally weathered, turned during the process, and become powder ...

Abstract

The preparation method comprises the following steps: (1) airing shells, crushing the shells into fragments by using a crusher, then calcining the fragments at high temperature by using a high-temperature furnace, naturally cooling the fragments, and weathering the fragments into powder; (2) taking the powder prepared in the step (1), adding a trace element compound in proportion, and uniformly mixing to obtain a nutrient solid; 3, the nutrient solid matter, cane molasses and tap water are evenly mixed according to the proportion, the mixture is put into a container to be sealed and fermented, and the water nutrient suitable for penaeus vannamei aquaculture is obtained.The prepared nutrient can effectively improve the survival rate of penaeus vannamei by 50% or above and improve the growth speed by 100% or above, and the water nutrient is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of aquaculture animal protection, and in particular relates to a method for preparing nutrients in cultured water of Penaeus vannamei. Background technique [0002] In recent years, the success rate of Penaeus vannamei farming in different regions has been uneven, and a variety of farming models have flooded the market. However, many solutions are difficult to replicate successfully in different places. The root cause is that there are differences in the water bodies in different regions. In research at home and abroad, some researchers continuously monitored the content changes of various micronutrient indicators in the water body during the culture process of Penaeus vannamei in the closed culture water environment. The content of trace elements in middle water changed. [0003] For the farming technology of Penaeus vannamei, water regulation has always been a major consideration. It is an important rese...
