Total artificial scytosiphon lomentaria breeding technology

Abstract

The invention relates to a total artificial scytosiphon lomentaria breeding technology. The total artificial scytosiphon lomentaria breeding technology comprises the following steps: (1) performing germplasm preparation, namely preparing germplasm from scytosiphon lomentaria collected in the current year, or preparing the germplasm by the recovery of the germplasm stored in the previous years; (2) performing germplasm amplification, namely amplifying the germplasm of the scytosiphon lomentaria by using an airlift photo-bioreactor; (3) performing germplasm induction, namely inducing the germplasm of the scytosiphon lomentaria to generate a mature unilocular sporangium; (4) performing spore seedling collection, namely stimulating the unilocular sporangium to diffuse spores, and collecting the spores on a net curtain formed by blending vinylon and polyvinyl chloride; (5) performing indoor seedling breeding; (6) performing mariculture, namely performing mariculture in a raft culture manner for 60-80 days to breed commercial scytosiphon lomentaria of which the body length is 60-100cm, wherein 80-120 seedlings exist on a seedling rope which is 1cm long. According to the total artificial scytosiphon lomentaria breeding technology, the scytosiphon lomentaria breeding efficiency can be improved, and the stable yield of commercial seedlings is ensured. The technology has the advantages of high germplasm utilization rate, firm seedling adhesion, low breeding cost, good production benefit and the like, and can be widely applied to large-scale industrial breeding and artificial culture of the scytosiphon lomentaria.

Description

technical field

[0001] The invention relates to a seaweed cultivation technology, in particular to a technology for fully artificial cultivation of day lilies. Background technique

[0002] Cucumber ( Scytosiphon lomentaria ) belongs to Phaeophyta ( Phaeophyta ), which is a pan-temperate seaweed, is widely distributed in the coastal areas from Liaodong Peninsula in the north to Hailing Island in Guangdong Province in the south in my country. Hemerocallis has an alternate life history of heteromorphic generations. The macroscopic tubular algae is the gametophyte stage, and the microscopic filaments, cushion-like bodies and cushion-like bodies are the sporophyte stage. Filaments, cushions and cushion-like bodies can transform into each other under certain conditions. The key factor affecting the transformation is temperature. High temperature conditions can make filaments form cushion-like bodies and cushion-like bodies, while low temperature conditions make Cushionoids a...
