Indoor seedling raising method for porphyra haitanensis seedlings

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...

AI Technical Summary

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.
