Problems solved by technology

[0004] However, the existing method for preparing biological living rocks, as disclosed in the invention patent (CN 106852290 A) on the one hand, is to process the natural active living rocks after collection, and the natural active living rocks still need to be excavated in the cultivation system. use, does not have sustainability; on the other hand, such as the invention patent (CN 108112520 A), although it is disclosed that the oyster shells are crushed and then added with a binder to make artificial living stones, the living stones made by this method lack looseness. The porous structure does not have the function of high-efficiency filter materials, and its production method lacks "activation", that is, the process of using natural or artificial environments to allow beneficial microorganisms and benthic organisms to attach to the surface of active bioliths, so it only has The function of facing the landscape in the aquarium does not have the characteristics of natural active bioliths, which are porous and has high biodiversity, nor does it have the function of maintaining a nutrient-poor environment. It can only be used for fish farming and other low-nutrient requirements. Therefore, it is difficult to be called an active biological stone

preparation example Construction

[0042] The embodiment of the present invention also discloses a preparation method of artificial active biolith, which specifically includes the following steps:

[0043] (1) According to the above-mentioned a kind of artificial active biolith, each raw material is weighed; another coarse salt is added to water and dissolved to saturation to obtain saturated concentrated brine for subsequent use;

[0044] (2) Mix cement, sand and coarse salt evenly to obtain a dry mix; according to the volume ratio of the dry mix to saturated brine is 50:1, add saturated brine to the dry mix several times and mix well , until the mixture can be kneaded into shape;

[0045](3) Knead the mixture into the shape of active biological stone on the fine coral sand bed, put it in a cool place, and cover the surface with a cover, spray tap water on the surface with a watering can in the morning and evening to prevent it from cracking, and let it dry naturally for 3- 15d to get dry artificial stone;

...

Embodiment 1

[0049] Embodiment 1 of the present invention also discloses a preparation method of artificial active biolith, which specifically includes the following steps:

[0050] (1) First, put 20kg of white cement, 30kg of coral sand with a particle size of 1mm, and 30kg of coarse salt on the ground, and mix them thoroughly with a shovel. After mixing, pour 2L of saturated salt water into the mixture with a measuring cup, and immediately use a shovel Mix, mix evenly, add water and mix again, put on rubber gloves and grab a small amount of mixture, gently squeeze the mixture to form it without spreading.

[0051] (2) Then stack the mixture on the coral sand bed and knead it according to the aesthetic needs. After the kneading is completed, cover the non-woven fabric to make it dry. The next day, open the covered cloth and spray a small amount of tap water on the surface of the mixture with a watering can to prevent It cracks and repeats once a day until it is completely dry on the 7th d...

Embodiment 2

[0055] Embodiment 2 of the present invention also discloses a small amount of trial production method of artificial active biolith, which specifically includes the following steps:

[0056] (1) First, put 2kg of white cement, 4kg of coral sand with a particle size of 0.5mm, and 2kg of coarse salt in a bucket, put on rubber gloves and mix thoroughly, after mixing, pour 200mL of saturated salt water into the mixture with a beaker, and pour Immediately mix by hand, mix evenly, add water and mix repeatedly until a small amount of mixture is picked up, gently squeeze the mixture to form and not disperse.

[0057] (2) Then spread several layers of newspapers on the desktop, pile up the mixture and knead it according to the aesthetic needs. After the kneading is completed, cover the non-woven fabric to let it dry. The next day, open the covered cloth and spray a small amount with a watering can. Tap water on the surface of the mixture to prevent it from cracking, repeat once a day un...

Abstract

The invention discloses artificial activated biological stone and a preparation method and application thereof. The preparation method includes steps: adopting cement, gravel and coarse salt as raw materials, mixing, stirring well, sun-curing, and activating to finally obtain the artificial activated biological stone. The preparation method is simple, low in cost and good in breeding effect, damage to natural coral reefs is avoided, and the artificial activated biological stone has sustainability and is suitable for indoor coral small-scale artificial breeding and propagation and being used tobuild a coral breeding system comprising a large water body with more than 2 tons of water.

Description

technical field [0001] The invention relates to the technical field of reef-building coral cultivation, and more specifically relates to an artificial active living stone and its preparation method and application. Background technique [0002] Due to global climate change (abnormal high temperature and low temperature) and the influence of human factors, the coral reef ecosystem has been seriously damaged, resulting in the continuous shrinking of the global coral reef distribution area and serious global degradation. At the same time, due to its brilliant color and high ornamental value, coral has attracted much attention in the market; in addition, the high mortality rate of indoor coral artificial cultivation has also stimulated the strong demand for coral in the market. A combination of various factors has led to a shortage of corals in the market, and the demand for corals continues to grow. [0003] In order to reduce the destructive development of corals in the wild,...
