Problems solved by technology

The disadvantages are: red tides are prone to occur, seawater is easily polluted, and the laver seedlings will die; during the small flood tide, there is no wind or waves on the sea, the water flow is not smooth, and the sediment is deposited on the net curtain, which can easily suffocate the laver seedlings to death. The seawater temperature is high, and tiger moss is easy to grow on the net curtain, which makes the laver seedlings unable to grow, reduces the survival rate of laver seedlings, and reduces the yield of laver

Embodiment Construction

[0013] The specific content of the present invention will be described in detail below through specific embodiments.

[0014] The process of directly raising seedlings in the seedling room of laver with seedlings attached to net curtains includes the following steps:

[0015] (1) Pick mature laver in March, and put the picked laver into the freezer (frozen storage below -15°C);

[0016] (2), thaw by the end of April, put the laver that thaws in the container, stir to allow the ripe fruit spores to disperse in the water, and spray on the shells in the seedling pond by microscope counting;

[0017] (3) Dark light treatment for three days, after three days, gradually light according to the needs of light, and adjust the light in a timely manner according to weather changes;

[0018] (4), to the middle and late September, water pump flushes the seaweed seedlings on the shells onto the net curtain, and the net curtain is cultivated for 10-15 days in the nursery pond, and the water...

Abstract

The invention discloses a direct sprouting process in a nori spatfall screen seedling-culturing chamber. The nori seedling which is cultured by using the direct sprouting process in the nori spatfall screen seedling-culturing chamber has the advantages that the cells are steady and strong, the delayed effect of algal filament layers is sufficient, the nori is cultured in a seedling-culturing pool so the nori is free from being influenced by the red tide and small tide, the survival rate of nori seedling is high, and the output of nori is greatly increased.

Description

technical field [0001] The invention relates to a laver seedling raising process, in particular to a laver seedling raising process directly in a seedling growing room attached to a net curtain. Background technique [0002] The existing laver seedling-attached net curtain seedling cultivation room directly grows the seedling process, comprises the following steps: (1), picks ripe laver in March, puts the laver that picks into freezer (frozen storage below-15 ℃); (2), Thaw at the end of April, put the thawed seaweed into the container, stir to disperse the mature fruit spores in the water, and spray them on the shells in the seedling pond by microscopic counting; (3), dark light treatment for three days, after three days, According to the light requirements, the light will be gradually released, and the light will be adjusted in real time according to the weather changes; (4) In the middle and late September, the seaweed seedlings on the shells will be flushed with water to ...
