Embodiment 1

[0018] 1) From the wild half-leaf laver, select healthy algae with larger individuals, darker color and higher maturity as seed algae, wash them with sterilized natural sea water, squeeze the water and spread the seed algae on the Dry in the shade on the bamboo curtain to make it lose about 50% of the moisture, and put the algae stimulated by drying in the shade into a container filled with sterilized natural seawater (add 100 kilograms of water per kilogram of algae), stir the seawater continuously to promote the release of the fruit spores, take Microscopic examination of the water sample, when 10-20 fruit spores are observed at a magnification of 100 times, the algae are fished out, and the filtrate obtained after filtering with a 200-mesh sieve is the fruit spore water.

[0019] 2) Use the phytoplankton counting frame to count the number of fruit spores contained in the fruit spore water per milliliter of Porphyra half leaf, calculate the fruit spore water concentration, ac...

Embodiment 3

[0030] 1) From the wild half-leaf laver, select healthy algae with larger individuals, darker color and higher maturity as seed algae, wash them with sterilized natural sea water, squeeze the water and spread the seed algae on the Dry in the shade on the bamboo curtain to make it lose about 50% of the moisture, and put the algae stimulated by drying in the shade into a container filled with sterilized natural seawater (add 100 kilograms of water per kilogram of algae), stir the seawater continuously to promote the release of the fruit spores, take Microscopic examination of the water sample, when 10-20 fruit spores are observed at a magnification of 100 times, the algae are taken out, and the filtrate obtained after filtering with a 500-mesh sieve is the fruit spore water.

[0031] 2) Use the phytoplankton counting frame to count the number of fruit spores contained in the fruit spore water of each milliliter of Porphyra half leaf, and calculate the concentration of the fruit s...

Abstract

The invention relates to a method capable of promoting formation of sporangial branchlets of shell conchocelis of pyropia katadae, and belongs to the field of marine algae cultivation. The method capable of promoting the formation of the sporangial branchlets of the shell conchocelis of the pyropia katadae comprises the following steps: 1) collecting carpospores of the pyropia katadae; 2) inoculating shells with the carpospores of the pyropia katadae; 3) impelling fast algal filament growth of the shell conchocelis in a vegetative growth stage of algal filaments; and 4) increasing concentration of iron ions so as to induce transformation of the algal filaments from the vegetative growth stage to a developmental state when the shells are fully covered with vegetative algal filaments of theshell conchocelis of most of the pyropia katadae and the sporangial branchlets begin to appear, thereby allowing rapid formation of the sporangial branchlets. The method capable of promoting the formation of the sporangial branchlets of the shell conchocelis of the pyropia katadae is capable of promoting fast growth of the vegetative algal filaments of the shell conchocelis of the pyropia katadae,as well as allowing synchronous formation of the sporangial branchlets by the vegetative algal filaments without heating; and moreover, the risk of diseases, such as bacterial infection, large amountof heteroalgae attachment and the like, can be reduced in environment with relatively low water temperature, thereby improving success rate of artificial seedling-raising of the shell conchocelis ofthe pyropia katadae.

Description

technical field [0001] The invention belongs to the field of marine algae cultivation, and in particular relates to a method for promoting the formation of sporangia branches of shell filaments of Porphyra laver. Background technique [0002] Porphyra has high nutritional value and economic value, and is one of the most important cultivated seaweeds in my country. The laver cultivation methods in my country include vegetable altar cultivation, pillar cultivation, semi-floating raft cultivation and full floating raft cultivation. Due to the limited area of ​​vegetable altars, the source of seedlings depends on nature, and is easily affected by sea and meteorological conditions, the cultivation methods of vegetable altars are rare. At present, pillar cultivation and semi-floating raft cultivation methods have been widely used in the cultivation industry of Porphyra zebra and Altar Porphyra. They are applied in the intertidal zone or near-shore sea area, allowing Porphyra to p...
