Embodiment 1

[0053] A method for extruding fruit spores released from altar laver for multiple times, comprising the following steps:

[0054] (1) Vegetables to promote ripening: Select and cultivate healthy altar laver vegetables on the breeding raft, gradually reduce the drying time, and promote the maturity of the vegetables; when obvious dark red plaques appear in the individual vegetables, microscopic examination It is found that the cell division is obvious and the protoplasm is thick, and the ripening of the vegetables is completed; the vegetables for the ripening are collected in time, washed, dried until the water content is 28-30%, and then stored;

[0055] (2) Vegetable inspection: after the ripening of the vegetables in step (1) is completed, the health status, water content and maturity of the vegetables after the ripening are detected: the color and luster of the vegetables after the ripening are normal, and the edges are complete. Good growth; the moisture content is 28-30%,...

Embodiment 2

[0063] In embodiment 1, the extruding device that uses is the planting vegetable extruding device that altar laver repeatedly releases fruit spores, comprises rotating wheel 2, screw rod 3, extruding bracket 4, extruding box 1, extruding plate 5, Shelf 6. Wherein the bottom surface side length of extrusion box 1 is the square of 0.6 meters, and height is 1 meter, and the material around is screw steel, and diameter is 12 or 16mm. In the middle of the extrusion box 1 is a screw rod 3, a diameter of 20 or 24mm threaded steel, a rotating wheel 2 is arranged on the screw rod 3, and the bottom is an extrusion plate 5, which is connected with the extrusion box 1 by an extrusion bracket 4. When the altar seaweed needs to be extruded, it is packed into the vegetable-growing bag 10, and the vegetable-growing bag 10 is then placed in the extrusion box 1. If there are multiple, the vegetable-growing bags 10 are placed with compartments 6, which is conducive to improving Squeeze effect. ...

Abstract

The invention discloses an extrusion method of porphyra haitanensis seed vegetables for repeatedly releasing carpospores. The method comprises the following steps: maturation promoting is performed onthe porphyra haitanensis seed vegetables, the moisture ratio of the seed vegetables after maturation promoting is 25-35%, and the area ratio of deep red patches to the whole thallus is about 15%; theseed vegetables after maturation promoting are put into seawater to release the carpospores, and the carpospores are inoculated on conches; the porphyra after releasing the carpospores is fished out,and packed into a double-layer plastic net bag after the porphyra is washed, and then sent to an extrusion apparatus to be subjected to extrusion, and the seawater after the porphyra is washed and the extrusion water are combined and inoculated on conches as a spore water; and the moisture ratio of the extruded porphyra is made to be 25-35% through water evaporating, then the porphyra can be preserved as the seed vegetables and can continue to release the carpospores as the seed vegetables. According to carpospores repeated releasing of the porphyra haitanensis seed vegetables, the deficiencyof seed vegetable insufficiency is solved, and the utilization rate of specific high-quality seed vegetables is improved. The method has the advantages of convenient operations and simple managements, and the efficiency and the benefit of seedling-raising and cultivation can be significantly improved.

Description

technical field [0001] The invention relates to a vegetable-planting extrusion method for repeatedly releasing fruit spores of Porphyra laver, belonging to the technical field of seaweed seedling cultivation. Background technique [0002] Porphyra laver is one of the economical seaweeds with the highest output value in the world. Porphyra laver is rich in nutrition and delicious in taste. The content of crude protein in dry product is more than 30%, and it contains vitamin A, vitamin C, various essential amino acids, polysaccharides, Substances and minerals such as oligosaccharides, dietary fiber and trace elements have special effects on improving various diseases of the modern population. Large-scale cultivation of Porphyra can consume a large amount of nutrients such as nitrogen and phosphorus in seawater, reduce the degree of eutrophication in the coastal waters, and have important ecological restoration and protection significance for the marine environment. The altar ...
