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 Euc

Example Embodiment

[0025] Example 1

[0026] (1) Take 30 healthy Eucheuma sprouts (30g each), drain the water on the surface, and place 5 of them directly in the sea for cultivation as an experimental control. In addition, the other 25 Eucheuma seedlings were placed in a foam box (the size of the foam box is about 50 cm wide × 80 cm long × 30 cm high) and stored in water.

[0027] Before the seedlings are placed in the foam box, place a towel soaked with seawater on the bottom of the foam box as a water-retaining material. After placing a layer of seedlings, add a layer of wet towels on top of the seedlings, and then continue to put the remaining seedlings Put it in the box, and finally put a layer of wet towel on the top of the seedlings. The humidity of the towel is subject to not dripping outside.

[0028] During the above operation, avoid squeezing the seaweed forcefully and causing unnecessary breakage and other damage.

[0029] (2) Place the foam box in an incubator with a temperature of 14.0±1.5...

Example Embodiment

[0034] Example 2

[0035] (1) Sampling according to the method in Example 1, placing Eucheuma serifolia seedlings and laying seawater-soaked towels.

[0036] (2) Place the foam box in an incubator with a temperature of 17.0±1.5°C and a dark light. After storing for different time (days), randomly pick 5 Eucheuma spp. and grow them in the sea again, and measure Eucheuma spp. The weight of the vegetables in the first two weeks after being raised in the sea and their vigor was observed. The results are shown in Table 2.

[0037] Table 2. Under the temperature of 17.0±1.5℃ and the dark conditions, the fresh weight of Eucheuma selenchus was stored for different time away from water, and the fresh weight changes within two weeks of cultivation at sea

Example Embodiment

[0039] Example 3

[0040] (1) Sampling according to the method in Example 1, placing Eucheuma serifolia seedlings and laying seawater-soaked towels.

[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 times (days). Randomly take out Eucheuma serrata, and take 5 plants each time and hang them in the sea again to determine the dents The weight of Eucheuma in the first two weeks of growing in the sea, and the analysis of the vitality of sea vegetables, the results are shown in Table 3.

[0042] Table 3. The fresh weight changes of Eucheuma selenchus at 23.0±1.5°C and dark conditions stored away from water for different periods of time after being cultivated on the sea for two weeks

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...
