Problems solved by technology

The disadvantages of the hanging breeding method: firstly, the lower shells are often greatly affected by the shading of the upper shells, the surface and bottom shells receive inconsistent light, and the shell filaments grow unevenly. Although the shells are often exchanged up and down during the actual cultivation process The hanging position achieves the goal of uniform growth of the upper and lower layers of shell filaments, but only some shell strings have less sunlight, and the growth of shell filaments is slow. Due to frequent replacement of hanging shell strings, it is necessary to untie and re-tie them. The labor intensity of seedling management is also relatively high
The second is that it is difficult to wash the shells. When washing directly with a water gun, the upper and lower layers of shells block each other, and the cleaning effect is not good. It is necessary to put away each hanging string of shells for cleaning, and then hang them back. The labor intensity of seedling management is also relatively high.

Embodiment 1

[0008] An indoor seedling raising method for seaweed seedlings is to manage the seedlings of shell strings inoculated with free filaments immersed in a seedling raising pool, the distance between two broad sides of the seedling pool is 2 meters, There are 0.2-meter-wide shelves on the edges for hanging. One end of the shell string is tied with a hanging rod, and the other end is tied with a sinking rod. The hanging rod and the sinking rod can be bamboo rods or plastic rods. Soak for 1 month before use. Left and right, the length of the hanging rod and the sinking rod is 1.8 meters. At the beginning of April, the free filaments were sprayed and inoculated into the shells of the shell string. Move the hanging rod so that the sinking rod and the hanging rod are misaligned on the plane, and their vertical lines form an included angle of 45 degrees, so that the shell strings are distributed in an arc-shaped oblique distribution in the nursery pond, and the shell strings are more eve...

Embodiment 2

[0010] Basically the same as Example 1, the difference is that the spacing between the two broad sides of the seedling pond is 1.5 meters, the shelf width is 0.1 meters, the length of the hanging rod and the sinking rod is 1.4 meters, and the vertical line between the sinking rod and the hanging rod is 1.4 meters. The angle formed between them is 30 degrees, and the hanging rod and the sinking rod exchange positions every 30 days.

Embodiment 3

[0012] Basically the same as Example 1, the difference is that the spacing between the two broad sides of the seedling pond is 1.3 meters, the shelf width is 0.1 meters, the length of the hanging rod and the sinking rod is 1.2 meters, and the vertical line between the sinking rod and the hanging rod is 1.2 meters. The angle formed between them is 60 degrees, and the hanging rod and the sinking rod exchange positions every 28 days.

Abstract

The invention discloses an indoor seedling raising method for porphyra haitanensis seedlings. The method comprises seedling raising management of a shell string soaked in a seedling raising pool and inoculated with free protonema, wherein the seedling raising management comprises shell washing management of the shell string; a hanging rod is tied to one end of the shell string; shelves for hanging are arranged on the inner brims of two wide edges of the seedling raising pool; a sinking rod is tied to the other end of the shell string; the hanging rod and the sinking rod can be laid on the shelves in length and are shorter than the distance between the two wide edges of the seedling raising pool; when the hanging rod is hung on the shelves, the sinking rod is sunken to the bottom of the seedling raising pool, and the positions of the sinking rod and the hanging rod are exchanged every 25 to 30 days; when the sinking rod is hung on the shelves, the hanging rod is sunken to the bottom of the seedling raising pool, and the included angle between the vertical line of the sinking rod and the vertical line of the hanging rod is 30 to 60 degrees; and the shell washing management means to flush the shell string directly by using a water gun. The indoor seedling raising method for the porphyra haitanensis seedlings is uniform in lighting of the shell string and low in labor intensity of the seedling raising management.

Description

technical field [0001] The invention relates to a technology for raising seaweed seeds and seedlings, in particular to an indoor seedling raising method for seaweed seedlings. Background technique [0002] Seaweed seedling raising is a seedling raising technique for the management of shell seedlings soaked in the seedling pool and inoculated with free filaments, that is, the fruit spores or free filaments are sprayed and inoculated into the shells from the beginning of April every year, and in the seedling pool In the process of cultivation, shell filaments are formed, and then the shell filaments are cultured. After filamentous algal filaments, sporangium branch formation, conchosporangium growth and development, and conchospore release, the shell needs to be washed once every two weeks during the cultivation process. Shell management, shell washing management can be washed with a soft brush, or washed with a water gun; by September, the conchospores are collected and cult...
