Embodiment 1

[0022] (1) The pure-line fine-bred filamentous germplasm is cultivated in the seedling pond of provenance isolation, and the conchospore seedlings are collected after the filamentous seedlings are mature;

[0023] (2) Pure-line fine seed seedling nets are cultivated in isolated sea areas to restore reproductive habits, and cultivated until the algae mature to form male and female germ cells.

[0024] (3) Collect mature algal bodies on the net of the pure-line fine-bred cultivation, which is the fine-bred F 1 Substitute algae;

[0025] (4) Wash the seed algae with clean seawater, dehydrate, dry in the shade or store at -20°C, and then it can be used for cultivating fine seedlings.

[0026] (5) It is the popularized improved variety F that is used to collect fruit spores and carry out seedling cultivation 1 Substitute algae.

[0027] In the step (1), the cultivation of fine-bred filamentous seedlings needs to be carried out in a seedling pond where the provenance is isolated,...

Abstract

The invention relates to a method for applying and popularizing porphyra yezoensis fine seeds. The method includes the steps of (1) pure fine seed protonema germplasm, wherein shell protonema cultivation is conducted in a nursery pond isolated from a seed source, and conchospore seedling picking is conducted when the protonema is mature, (2) pure fine seed seedling net sea area cultivation, wherein breeding trait recovery is conducted, (3) picking mature fine seed F1 generation algal bodies which serve as the seed algae, (4) cleaning the seed algae with clean sea water, conducting dehydration on the seed algae, drying the seed algae in shade for later use or storing the seed algae at -20 DEG C for later use, wherein the obtained seed algae can be used for fine seed productive carpospores collection, and seedling picking and seedling cultivation can be conducted. The method for applying and popularizing the porphyra yezoensis fine seeds solves the production problems that when the fine seed free protonema is inoculated to shell seedling, later-period maturity promotion measures are not easy to control, conchospore seedling picking efficiency is low, the fine seeds are not easy to cultivate and popularize, and large-scale fine seed seedling and seed supply are achieved. Through the technology, fine seed application has more operability and higher popularization, and the mass production progress of the porphyra yezoensis fine seed is promoted.

Description

technical field [0001] The invention belongs to the field of application of improved varieties of laver, and in particular relates to a method for application and popularization of improved varieties of laver. Background technique [0002] Porphyra is a seaweed that grows in the intertidal zone along the coast. ), Porphyra. Seaweed is delicious and has always been the seaweed picked and eaten by coastal people. At present, Porphyra japonica in the south and Porphyra zebra in the north are important economically cultivated seaweeds in my country. [0003] The main production area of ​​Porphyra variegata in my country is located along the coast of Jiangsu Province, and the provenance of cultivated Porphyra comes from wild populations in Qingdao, Shandong. In the traditional method of raising laver seedlings, the cultivator selects algae from the thallus populations of cultivated laver every spring, or collects the original algae from the naturally distributed wild populatio...
