Problems solved by technology
[0004] However, in the actual breeding process, it was found that multi-crop cultivation of kelp is carried out all year round in the deep sea high area. If only summer seedlings are used, it cannot meet the needs of breeding seedlings. Therefore, multi-crop seedlings in spring, autumn and winter must be carried out.

Embodiment Construction
[0012] The present invention will be further described below in conjunction with embodiment.
[0013] What the present embodiment provides is, in March 2009 to January 2010, carry out the method for multi-crop seedling raising of kelp, which includes four seedling stages of spring seedling, summer seedling, autumn seedling, and winter seedling raising of kelp, the multi-crop seedling raising of kelp The schedule for:
[0014] Spring seedling raising: from March 13, 2009 to April 20, 2009, the seedling raising time is 37 days;
[0015] Summer nursery: from August 13, 2009 to October 17, 2009, the seedling time is 65 days;
[0016] Autumn seedling raising: November 3, 2009-January 12, 2010, seedling raising time is 70 days;
[0017] Winter seedling raising: from December 11, 2009 to January 10, 2010, the seedling time is 30 days;
[0018] Spring seedlings, summer seedlings, autumn seedlings, and winter seedlings go through the following processes:
[0019] 1. Conservation of...

The invention relates to a multi-stubble kelp seedling culture method, in particular to a conventional kelp seedling culture method adopted in summer, which is characterized in that seedling culturing in spring, autumn and winter is carried out in April to May each year, the individuals not in the mature period are selected from a kelp culture colony as main weeds to be placed into a sea area with high depth, large flow and low temperature for nursing and aestivating, the culturing water layer of the individuals is controlled according to different temperatures of the sea water, thereby delaying the individuals to enter a full seed period and the mature period; 20-30 days before seedling culturing, the reserved main weeds are sequentially lifted to a water layer with the height of about 0.5 m for mature accelerating according to different seedling culturing time in autumn, winter and spring; and pulling seedlings, culturing indoors and removing young seeding out of a warehouse, and then adopting the measures of controlling light, water temperature and running water during culturing indoors, washing seedling beds and fertilizing. The invention solves the problem of the lack of seedling sources in multi-stubble seedling culturing, and the multi-stubble seedling culturing method has reasonable process and feasible operation.
Description
technical field [0001] The invention relates to the cultivation of seaweed, in particular to a method for multi-crop seedling cultivation of seaweed. Background technique [0002] Kelp is a large edible algae that grows in low-temperature seawater. Its growth process includes seedling stage, concave-convex stage, thin tender stage, thick mature stage, mature stage and aging stage. In the 1950s, my country carried out natural light and low temperature running water seedling cultivation and full artificial raft culture, which greatly increased the production of kelp. In northern my country, from mid-July to late-August (water temperature is lower than 22°C), the collected kelp spores are attached to the nursery curtains, and in the indoor nursery ponds, they are temperature-controlled, light-controlled, fertilized, washed, and watered. And other technical measures to cultivate sporophytes, and the sporophytes that meet the requirements for delivery from the warehouse are trans...
