Problems solved by technology

Although the survival rate of transplanted eelgrass is very high, it will cause great damage to the original resources
(2) In the current seed multiplication method, the germination rate is very low, mostly below 10%
(3) In the current transplantation and multiplication methods, divers are required to enter the water, and multiple underwater observations are required during the multiplication period, which is very costly

Embodiment 1

[0020] A method for multiplying eel algae seeds, specifically comprising the following steps:

[0021] (1) From late July to mid-August, collect the mature seeds of Zinnia spp. in the field and bring them back to the laboratory. After surface disinfection with 70% alcohol, store in 32 psu of fresh sea water that has been filtered and inflate at 17-20°C; change the water every 5 days; move to the refrigerator before planting, and gradually cool down to 4°C for 30 days, pay attention to lowering the temperature every day 2°C.

[0022] (2) Start sowing in mid-November. The specific method of sowing is:

[0023] ①Site selection for sowing: Choose a shrimp pond with a water depth of 40cm. The bottom is sandy and muddy, rich in organic matter, and the ratio of sand to mud is 1:3.

[0024] ②Make a transplant frame: make a 30×30cm transplant frame, the frame is made of PVC pipe, the diameter is 30mm, and the bottom of the frame is two layers of medical gauze:

[0025] ③Sowing: Dis...

[0030] A method for multiplying eel algae seeds, specifically comprising the following steps:

[0031] (1) From late July to mid-August, collect the mature seeds of Zinnia spp. in the field and bring them back to the laboratory. After surface disinfection with 70% alcohol, store in fresh seawater 32psu, store inflated at 17-20°C; change the water every 5 days; move to refrigerator before sowing, gradually cool down to 4°C and store for 30 days, pay attention to lower the temperature by 2°C every day.

[0032] (2) Start sowing in mid-November. The specific method of sowing is:

[0033] ①Site selection for sowing: Choose a shrimp pond with a water depth of 100cm. The bottom is sandy and muddy, rich in organic matter, and the ratio of sand to mud is 1:5.

[0034] ②Make transplantation frame: Make a 60×60cm transplantation frame, the frame is made of PVC pipe, the diameter is 30mm, and the bottom of the frame is two layers of medical gauze;

Abstract

The invention relates to a zostera marina seed multiplication method and belongs to the technical field of ocean resource recovery. The method particularly includes the following steps: (1), collecting zostera marine seeds, storing the seeds into fresh seawater 32psu after surface disinfection with alcohol of 70%, performing inflation saving at 17-20 DEG C, and saving in a refrigerator for 30 days at 4 DEG C before seeding; (2), starting to seed in the middle of November; (3), transplanting to a sea area in June next year, wherein the seeding method particularly includes 1, selecting a shrimp pond with water depth of 40-100cm and bottom sediment to be a sand-mud bottom; 2, making a transplanting frame; 3, seeding; 4, cultivating in the shrimp pond. During sea area transplanting, an area with water depth of subtidal zone to be 20cm, bottom sediment to be a sand-mud bottom and sand-mud proportion to be 1:3-1:5 is selected, and tidewater needs to have certain flow speed, 6cm/s properly. By the zostera marina seed multiplication method, damage to existing resources is avoided, zostera marina multiplication can be effectively performed, and effect of restoring zostera marine resource quantity is realized.

Description

technical field [0001] The invention relates to a method for multiplying eel algae seeds, and belongs to the technical field of marine resource restoration. Background technique [0002] Seagrass ecosystems, together with mangroves and coral reef ecosystems, are considered to be three typical offshore ecosystems. And international research results show that the ecological service value of seagrass fields is significantly higher than that of mangroves and coral reefs. Seagrass is the only angiosperm that submerges in shallow water, and differentiates into organs such as roots, stems, leaves, flowers and seeds. Lush seagrass fields are like forests on land, an important symbol of a healthy marine environment, and are precious "undersea grasslands" or "undersea forests". Seagrass fields are high-productivity areas that can provide good habitats, nursery grounds and shelters for marine organisms such as fish, shrimps, crabs, and shellfish. They are also conducive to the habita...
