Seaweed cultivation method

Abstract

The invention provides a method for culturing seaweed, which belongs to the technical field of seaweed cultivation, comprising: 1 induction culture, adding an induction auxiliary agent to the culture solution, successively inducing and culturing the female gametes of seaweed in a closed environment and in a continuous air environment to obtain parthenogenetic Reproductive mature sporophyte; 2 female gamete development, sporophyte cultured and developed into mature female gametes in fresh seawater; 3 fertilization and development, mature male gametes and induced mature female gametes were fertilized in fresh seawater with weak current Develop to larval sporophytes; 4 carry out mariculture. Beneficial effects are: the method helps to deepen the color of the cultivated seaweed algae, promotes its photosynthesis, accelerates the synthesis of matter and energy, and the method also helps to accelerate the formation of young roots and accelerate the growth of seaweed. The content of unsaturated fatty acid is significantly improved, and the nutritional value and economic value of seaweed are enhanced.

Description

technical field [0001] The invention belongs to the technical field of seaweed cultivation, and in particular relates to a cultivation method for seaweed cultivation. Background technique [0002] "Seaweed" is the general term for marine algae such as kelp, seaweed, wakame, and aquamarine. It is an algae that grows in the sea and is a cryptogamous plant in the plant kingdom. Algae include several different types of organisms that generate energy through photosynthesis. They are generally considered to be simple plants, the main features are: no vascular tissue, no true differentiation of roots, stems, and leaves, no flowering, no fruits and seeds, no specialized protective tissues for reproductive organs, and often directly produced by a single plant. Cells produce spores or gametes, no embryo formation. [0003] Seaweed is salty and cold in nature, and has the effects of clearing away heat, softening and resolving hard masses. People with spleen and stomach deficiency sho...

Problems solved by technology

[0005] Prior art PCT patent 00812730.1 discloses an improved method of cultivating seaweed, which uses antibiotics and fungicides to aseptically treat the growable seaweed material, and then controls the temperature and light on the PES-enhanced agar plate for 40 days. Isolate the callus, adjust the temperature and light, and cultivate asexual buds, then transfer to liquid PES medium and culture under vibration conditions to develop into immature embryos with multiple branches, and finally culture them in perforated polyethylene bags to realize algae growth. Scale cultivation; Chinese patent 2011200535395 discloses a ventilated culture bottle for seaweed cultivation, which has an upward vent pipe through the vent hole at the bottom of the culture bottle, and the mouth of the culture bottle is provided with a filter membrane, which is convenient for gas However, the seaweed cultivation methods and devices disclosed in the above-mentioned patented technology all have disadvantages such as complicated process, difficult conditions to control, high investment cost, and high labor intensity. Design an easy-to-implement, fast-speed, and high-efficiency seaweed cultivation method, which has good application prospects and implementation value
