Problems solved by technology

Therefore, the existing sea seedling preservation links are always facing some problems that seriously affect the survival rate of seedling preservation
The above factors are continuous and frequent occurrences. Failure to clean up in time will seriously affect the growth and development of Sargassum seedlings, and even fail to protect the seedlings, and the seedling curtains will be scrapped.
What's more, sea seedlings are still facing the threat of severe storm disasters and poor water quality in sea areas.

Embodiment Construction

[0018] The technical solution of the present invention will be further explained below in conjunction with the examples.

[0019] The invention discloses a method for preserving sargassum seedlings on land using underground salt water, including site selection, cultivation pool construction, underground water seedling preservation and summer, temporary cultivation and cultivation at sea.

[0020] Site selection: It must be a tidal flat with underground salt water resources, and meet various social requirements such as environmental protection. Or use the existing seedling breeding sites and groundwater wells to meet the requirements for the preservation of Sargassum seedlings by configuring a suitable seedling pond environment. Generally, sandy and gravel beaches are easier to drill saltwater wells, which is one of the most important conditions for site selection. The location of this example is on the east side of Laizhou Bay, the beach is a sandy beach, the saltwater well i...

Abstract

Disclosed is a method of carrying out sargassum thunbergii seedling protection on land by using saline groundwater. The method of carrying out the sargassum thunbergii seedling protection on land by using the saline groundwater comprises area selection, cultivating pool construction, saline groundwater seedling protection and summer pass, temporary rearing and cultivation on the sea. According to the method of carrying out the sargassum thunbergii seedling protection on land by using the saline groundwater, the advantages of the saline groundwater that the saline groundwater is stable in water temperature and clean in water quality are fully used. Hidden dangers that growth and development of the seedlings caused by the high temperature in summer is slow, the seedlings are taken off in a large area caused by the high temperature in the traditional seedling protection production of the sargassum thunbergii seedling is solved. Harms and heavy management brought by the fact that a large quantity of creatures frequently attach on the seedling curtain faced by the sea seedling protection are avoided at the same time. Influences brought by the typhoon and the environment anormaly are avoided. Seedling adhesive rate and reliability of seedling protection are greatly improved. Enough seedling seeds provided for the sargassum thunbergii cultivation production are guaranteed.

Description

Technical field: [0001] The invention belongs to the technical field of algae propagation, and in particular relates to a method for using underground salt water to build ponds on land to preserve sargassum seedlings. Background technique: [0002] Sargassum thunbergii (Mert.) O. Kuntze is a common seaweed in the coastal intertidal zone of my country. Since the mid-1990s, the application value of sargassum has been more and more excavated. Especially in recent ten years, with the rise of my country's sea cucumber aquaculture industry, the demand for sargassum as a high-quality bait for sea cucumbers has grown rapidly. Wild seedlings have long been unable to meet the needs of breeding, because on the one hand, the distribution of sargassum resources is relatively scattered, and the rough method of cutting off the old perennial roots when collecting them has led to a rapid decline in the already limited wild sargassum resources. It is on the verge of depletion, and it is bec...
