Abstract

The invention provides a swinging-type automatic-flushing method for collecting indoor porphyra yezoensis conchospore seedlings. The method comprises the following steps of before conchospore seedling collection and during conchospore seedling collection, performing conchospore spreading condition inspection; performing running water stimulation on a discontinuous small-range indoor seedling raising pond by use of swinging-type flushing, so as to enable flushing to be gradually pushed forward. According to the method, single-point flushing is adopted, the flushing intensity is high, point-to-point curved flushing water which is approximately linear is performed and gradually pushed forward, and left-and-right swinging is adopted, so that the flushing intensity of each point on a broken line is nonuniform; the method is applicable to flushing of the small-range or discontinuous indoor seedling raising pond; by virtue of flushing, and the growth of filamentous alga filaments and the development of sporangial branch are promoted. The maturity and spreading of conchospores are promoted; the demersal conchospores are flushed to be fully in contact with a net curtain and attached to the net curtain, so that the spreading and attachment rate of the conchospores can be improved, and wastes of the conchospores are reduced; the net curtain is uniform in seedling collection and is put into a sea timely; the labor cost is reduced, and the porphyra yezoensis seedling raising cost is reduced.

Description

technical field

[0001] The invention relates to a laver cultivation technology, in particular to a method for indoor spore collection of Porphyra variegata spores by swinging automatic water flushing. Background technique

[0002] Seaweed is a natural marine food. It is delicious, nutritious, and has health care functions. It has been selling well in the international market. With the improvement of modern living standards, especially the enhancement of our people's awareness of food health care, people are paying more and more attention to it. The health function of seaweed has a large domestic market space and strong market competitiveness.

[0003] With the development of human civilization and the improvement of living standards, diseases such as "rich man's disease" hypertension, cardiovascular and cerebrovascular diseases are increasingly endangering human health. Laver has the natural functions of lowering blood pressure and enhancing the elasticity of blood vessels,...

Embodiment Construction

[0025] A method of swinging automatic flushing for indoor seedling collection of Porphyra zebra spores:

[0026] During the cultivation of shell filaments and before and after conchospore seedling collection, observe the color change of shell filaments and the extent of filaments covered with shells with the naked eye; check the dissolution of shells with Perlani solution; During the period, check the release of conchospores;

[0027] For indoor seedling ponds that are not in a small area, swinging flushing water is used for water stimulation. A swinging flushing device is installed on the pool stem or under the support beam of the nursery room ceiling. The swinging flushing device includes setting on the pool stem or the nursery room. The double-track runway under the roof support beam is equipped with a mobile trolley that can walk by remote control. The mobile trolley is equipped with a swing arm driven by a motor that can swing left and right. There is a flushing water pum...
