Stereoscopic culturing system and method of porphyra yezoensis shell protonema

Abstract

The invention relates to a stereoscopic culturing system and method of porphyra yezoensis shell protonema. The stereoscopic culturing system comprises a plurality of culturing tanks which are distributed stereoscopically, a water storage tank is arranged under the culturing tanks and leads water into the culturing tanks through a water circulation system, and the culturing tanks are each further provided with an artificial light source used for culturing shell protonema. The culturing method includes the steps that light is regulated, wherein 400-500 nm of blue light and 600-700 nm of red light are the main, and light sources at other spectral lines are also taken into account; the intensity ratio of the red light to the blue right is regulated between 4:1 and 12:1; light intensity is controlled between 500 Lux and 5000 Lux; the daily illumination time of the artificial light sources is regulated between 8 hours and 18 hours. The stereoscopic culturing system and method of porphyra yezoensis shell protonema can improve the reliability of seedling culturing production, shorten the culturing period of shell protonema, flexibly arrange the harvesting time of conchospore, and largely reduce the production cost.

Description

technical field [0001] The invention relates to the technical field of cultivating Porphyra zebra shell filaments, in particular to a three-dimensional culture system and a cultivation method for Porphyra zebra shell filaments. Background technique [0002] The cultivation of seaweed shell filaments is the main technical connotation of the seaweed seedling cultivation project. The existing technology relies on the plane structure conditions of the cement pool and adopts an open water-changing cultivation mode. [0003] The current steps of Porphyra zebra seedling cultivation technology are: from mid-April to early May every year, inoculate the fruit spores (or crushed fragments of free filaments) of mature Porphyra on the shells that are tiled in the cement pool, and after about 5 After one month of cultivation (suitable seawater conditions and light and temperature conditions are required), the nacre of the shells is gradually covered with filaments. Under the stimulation o...

Problems solved by technology

Because the open cement pool model is difficult to get rid of the dependence on natural climate conditions, the existing technology has great limitations in the time selection, and generally can only be inoculated with fruit spores (or filaments) from mid-April to early May every year. ), from late September to early October

On the one hand, this natural limitation stipulates a longer cultivation period, on the other hand, it often occurs that the time for collecting seedlings of conchospores conflicts with the suitable time for launching seedling nets into the sea, and most manufacturers need to increase the "refrigeration" link to connect The time difference between laver seedling cultivation and sea cultivation increases management costs and production risks
