Problems solved by technology

However, the problem with this technology is that it is not easy to firmly adhere living coral branches to the glass plate. It is difficult to find glue with this special performance on the market. For the massive Porites coral, the species most commonly used in marine paleoenvironmental studies
A university in Taiwan, in order to solve the cultivation of massive Porites, adopts the method of isotope tracer. Although this method can effectively distinguish the old and new coral parts, it requires a lot of investment in the measurement, and it is difficult to popularize and apply.
The present inventor has also explored how to deposit newly grown coral skeletons on a relatively independent carrier in Porites culture, such as binding the cut block Porites on a polyethylene board to make the new section of corals tightly Pasted on the board but was unsuccessful

Embodiment 1

[0033] Embodiment 1 A kind of cultivation method of new growth coral sample in the indoor coral culture of scientific research (see figure 1 ), including the following steps:

[0034](1) Sampling:

[0035] Cut the healthy branched corals into several branches, drill several holes on the polyethylene plate with a thickness of 2-5mm, and insert the coral branches into the drill holes; the diameter of the drilled holes is the same as the diameter of the coral branches match (see image 3 ).

[0036] (2) Cultivation: put the coral samples of step (1) gained into culture systems (provided by the Qinghai Institute of Salt Lakes, Chinese Academy of Sciences) with different salinities or different pH values ​​or different temperatures for cultivation; through 10 to 20 days, There will be a coral skeleton deposition ring (brown part) around the drilling hole of the polyethylene board, indicating that the coral begins to grow on the polyethylene board and continue to grow, the coral...

Embodiment 2

[0039] Embodiment 2 A kind of cultivation method of new growth coral sample in the indoor coral culture of scientific research (see figure 2 ), including the following steps:

[0040] (1) Sampling:

[0041] Drill several holes in Porites massive and insert several pipe rods into the holes; where the diameter of the pipe rods matches the diameter of the drill holes (see Figure 4 ).

[0042] (2) Cultivation: put the coral samples of step (1) gained into culture systems (provided by the Qinghai Institute of Salt Lakes, Chinese Academy of Sciences) with different salinities or different pH values ​​or different temperatures for cultivation; through 10 to 20 days, There will be a coral skeleton deposition circle (brown part) on the pipe rod, indicating that the coral begins to grow on the pipe rod. Continue to culture, the coral skeleton deposition ring will continue to expand upwards, and stop when the total amount of coral skeleton deposition is 200-1000mg cultivate.

Embodiment 3

[0045] Embodiment 3 A kind of cultivation method (see figure 2 ), including the following steps:

[0046] (1) Sampling:

[0047] Make several grooves on the block Porites, and insert several sheets into the grooves; the thickness of the sheets matches the width of the grooves (see Figure 5 ).

[0048] (2) Cultivation: put the coral samples of step (1) gained into culture systems (provided by the Qinghai Institute of Salt Lakes, Chinese Academy of Sciences) with different salinities or different pH values ​​or different temperatures for cultivation; through 10 to 20 days, There will be a coral skeleton deposition ring (brown part) on the sheet, indicating that the coral begins to grow on the sheet. Continue to culture, and the coral skeleton deposition ring will continue to expand upwards. When the total amount of coral skeleton deposition is 200-1000mg Stop breeding.

Abstract

The invention relates to a method for cultivating new coral samples in indoor coral culture for scientific researches, which comprises the following steps of: (1) sampling, namely, cutting columnar corals into single branches, drilling holes on a polyethylene plate and inserting the coral branches into the drilled holes, or drilling the holes or reserving slots on blocky porites and inserting tubular or sheeted objects into the drilled holes or reserved slots; (2) cultivation, namely, placing the coral samples obtained by the step (1) into a cultivation system for cultivation, and stopping the cultivation when 200 to 1,000 milligrams of coral skeletons are deposited; and (3) the collection of the new coral samples, namely, pulling the coral branches out of the drilled holes, and strippingthe coral skeleton depositions off the polyethylene plate, or taking the tubular or sheeted objects out of the drilled holes or the reserved slots, and stripping the coral skeleton depositions off the tubular or sheeted objects, wherein the coral skeleton depositions are the new coral samples. The method is simple, convenient and easy; and the obtained new coral samples are well delimited from the conventional corals, and can be conveniently and effectively collected.

Description

technical field [0001] The invention relates to a method for cultivating corals, in particular to a method for cultivating newly grown coral samples in indoor coral cultivation for scientific research. Background technique [0002] Coral is a kind of marine organism. The boron and oxygen isotopic composition of coral skeleton calcium carbonate (aragonite) and its trace element content are widely used as proxy indicators for surface seawater pH, temperature (SST) and salinity (SSS). Coral skeleton calcium carbonate records the information of surface seawater pH, SST and SSS, so it can be used to reconstruct the pH value, SST and SSS of ancient seawater. However, the feasibility of this technology needs to be verified by coral culture experiments at different pH, different temperature or different salinity, and indoor coral culture for scientific research must solve three problems: [0003] 1. First of all, it is necessary to ensure the normal growth of corals under controlle...
