Problems solved by technology

Because the high-density Eucheuma serrata is easy to secrete halogenated hydrocarbons in still seawater, which will soon cause the algae to become soft and rot. Therefore, how to keep Eucheuma serrata alive during transportation (especially long-distance transportation) is the key to the cultivation of this algae. One of the most important technologies in the process. At present, there is no method for the effective preservation and transportation of Eucheuma serrata in the world.
In the past, during the long-distance transportation of the seaweed seedlings, the seaweed often rotted and died due to high temperature, or the seaweed suffered from chilling damage or even freezing damage due to improper cooling, which also led to a decline in the vitality of the seaweed; similarly, humidity control during out-of-water transportation is very important.

Embodiment 1

[0026] (1) Take 30 healthy Eucheuma serrata seedlings (30g per plant), drain the water on the surface, and place 5 of them directly in the sea for hanging culture as an experimental control. In addition, the other 25 Eucheuma serrata seedlings were stored in a foam box (the size of the foam box was about 50 cm wide x 80 cm long x 30 cm high) and stored away from the water.

[0027] Before the seedlings are placed in the foam box, place a towel soaked in seawater at the bottom of the foam box as a water-retaining material, place a layer of seedlings, and then place a layer of wet towels on the top of the seedlings, and then continue to put the remaining seedlings Put it into the box, and finally spread a layer of wet towel on the top of the seedlings. The humidity of the towel is based on the fact that no water drips out.

[0028] During the above operation process, avoid unnecessary breakage and other damage caused by squeezing the seaweed.

[0029] (2) Place the foam box in ...

Embodiment 2

[0035] (1) Take samples according to the method in Example 1, place Eucheuma serrata seedlings and lay towels soaked in seawater.

[0036] (2) Place the foam box in an incubator with a temperature of 17.0±1.5°C and a dark light. During storage for different periods (days), randomly pick 5 Eucheuma serrata, hang them again in the sea for cultivation, and measure Eucheuma serrata. The weight of the two weeks before the vegetables were hung in the sea was observed for their vigor, and the results are shown in Table 2.

[0037] Table 2. Under the condition of temperature 17.0±1.5℃ and darkness, the change of fresh weight of Eucheuma serrata stored out of water for different periods of time in hanging culture at sea for two weeks

[0038]

Embodiment 3

[0040] (1) Take samples according to the method in Example 1, place Eucheuma serrata seedlings and lay towels soaked in seawater.

[0041] (2) Place the foam box in an incubator with a temperature of 23.0±1.5°C and a dark light, store it for different periods of time (days), take out Eucheuma serrata randomly, take 5 plants each time and hang them in the sea again, and measure the The weight of Eucheuma in the sea for two weeks before being raised in the sea was used to analyze the vitality of sea vegetables, and the results are shown in Table 3.

[0042] Table 3. Under the condition of temperature 23.0±1.5℃ and darkness, Eucheuma serrata stored out of water for different periods of time, the change of fresh weight within two weeks of hanging culture at sea

Abstract

The invention belongs to the technical field of marine organisms, particularly to a keep-alive conveying and seed preservation method of rubber production tropical seaweed eucheuma denticulatum. The eucheuma denticulatum and moisturizing materials are placed into a 17.0 to 23.0 DEG C of storage device together under the dark condition and the 80 plus or minus 20% of relative humidity after water-leaving treatment is performed on the eucheuma denticulatum and accordingly the storage time can be extended and the long time keep-alive conveying of the eucheuma denticulatum can be achieved. The keep-alive conveying and seed preservation method of the eucheuma denticulatum is simple and practicable, the keep-alive period is long, the keep-alive conveying and seed preservation method is suitable for long-distance conveying of seedlings of the eucheuma denticulatum, farmers can harvest the seedlings ahead of time in a typhoon period, the seedlings can be safely stored, and losing of the seedlings can be avoided.

Description

technical field [0001] The invention belongs to the technical field of marine organisms, and in particular relates to a method for keeping alive, transporting and seed preserving the gum-producing tropical seaweed Eucheuma denticulatum. Background technique [0002] Eucheuma serrata is the main raw material for producing iota-carrageenan in the world. And ι-carrageenan is very suitable for processing semi-solid and liquid fruit juices, beverages, condiments, toothpaste, cosmetics, etc. In the pharmaceutical industry, plant-based film coating has no cross-linking reaction, low drug hygroscopicity, and no animal source. Risk of infectious diseases, not easy to react with aldehyde-containing drugs, easy to reuse waste materials and high profits, and iota carrageenan is the best plant-based raw material for preparing medicinal material coatings. Internationally, the cultivation of Eucheuma serrata is mostly carried out in tropical and subtropical regions, and Eucheuma serrata i...
