Embodiment 1

[0029] A method for establishing a continuous high-efficiency artificial cultivation system of seaweed, comprising the following steps,

[0030] A. Absorb algae seeds and cultivate them in a transparent measuring cup. The culture temperature is controlled at 18°C, the photoperiod is 12L:12D, and the light intensity is controlled at 80μmol / m 2 / s, change the sterilized seawater every 2 days while ventilating with a sterilized airway, add 0.5% nutrient solution, and take seaweeds longer than 8mm as algae seedlings;

[0031] B. the algae seedlings of step A cultivating the initial amount of input in the first-level culture tank are cultivated, after t days, the seaweed in the first-level culture tank is taken and placed in the second-level culture tank for cultivation, and the initial amount is input in the first-level culture tank simultaneously. After t days, take out the seaweed in the secondary cultivation tank and put it into the third-level cultivation tank for cultivation,...

Embodiment 2

[0034] A method for establishing a continuous high-efficiency artificial cultivation system of seaweed, comprising the following steps,

[0035]A. Cultivate algae seeds in a transparent measuring cup.

[0036] B. the algae seedlings of step A cultivating the initial amount of input in the first-level culture tank are cultivated, after t days, the seaweed in the first-level culture tank is taken and placed in the second-level culture tank for cultivation, and the initial amount is input in the first-level culture tank simultaneously. After t days, take out the seaweed in the secondary cultivation tank and put it into the third-level cultivation tank for cultivation, while taking ou...

Embodiment 3

[0046] A method for establishing a continuous high-efficiency artificial cultivation system of seaweed, comprising the following steps,

[0047] A. Absorb the algae seeds and cultivate them in a transparent measuring cup. The culture temperature is controlled at 20°C, the photoperiod is 12L:12D, and the light intensity is controlled at 100μmol / m 2 / s, change the sterilized seawater every 2 days while ventilating with a sterilized airway, add 0.5% nutrient solution, and take seaweeds longer than 8mm as algae seedlings;

[0048] B. the algae seedlings of step A cultivating the initial amount of input in the first-level culture tank are cultivated, after t days, the seaweed in the first-level culture tank is taken and placed in the second-level culture tank for cultivation, and the initial amount is input in the first-level culture tank simultaneously. After t days, take out the seaweed in the secondary cultivation tank and put it into the third-level cultivation tank for cultiva...

Abstract

The invention relates to the technical field of seaweed cultivation, and discloses a method for building a continuous efficient artificial seaweed cultivation system. The method comprises the steps of establishing the continuous efficient artificial seaweed cultivation system, determining the initial cultivation input amount W'0 of the system, evaluating the harvesting amount, determining the culture period, and determining the size of each cultivation tank at each stage. The cultivation tanks are used in a serial connection way and regarded as an integral cultivation system, the maximum biomass can be obtained in a limited space, the harvesting amount is continuous, and the harvest period is greatly shortened. The growth period, the growth coefficient R and the relative growth rate mu of the seaweeds can be artificially controlled according to the growth state of the seaweeds. According to the size of the last stage of the cultivation tank in the cultivation system, the growth coefficient R and the number of the cultivation tanks, the size of the cultivation tanks in other stages in the system can be determined. According to a regular formula of the growing periodicity of the cultivation objects, the initial input amount, the harvesting time and the harvesting amount are set.

Description

technical field [0001] The invention relates to the technical field of seaweed cultivation, in particular to a method for establishing a continuous and efficient artificial cultivation system of seaweed. Background technique [0002] The 21st century is the century of development and utilization of marine resources, and the most abundant resource in the ocean is seaweed. Seaweed can effectively use light energy, carbon dioxide and inorganic salts to synthesize proteins, fats, carbohydrates and a variety of high value-added active substances, and can produce healthy and safe food, food additives, animal feed, biological fertilizers and other natural products. With the development and utilization of marine algae, the demand for algae is increasing day by day, and the wild algae growing in natural sea areas can no longer meet the demand of market quantity and quality. [0003] At present, traditional algae cultivation basically mainly transports young algae seedlings to natur...
