Breeding method of kelp winter seedlings

Abstract

The invention provides a breeding method of kelp winter seedlings. The breeding method of the kelp winter seedlings comprises the following steps of S1, cultivating kelp; S2, collecting seedlings; and S3, raising the seedlings. According to the breeding method of the kelp winter seedlings, the technical blank that no winter seedlings exist in traditional kelp is filled, production of seedling breeding enterprises and breeding activities of farmers are not interrupted, the seedling breeding enterprises can breed more kelp seedlings in one season, the farmers can breed more kelp seedlings in one season, great economic benefits are created for the society, and the income level of related enterprises and farmers is improved.

Description

technical field [0001] The invention relates to the technical field of kelp seedling cultivation, in particular to a method for breeding winter kelp seedlings. Background technique [0002] Kelp is the single species with the largest farming area and output in the world. Since the 1980s, the scale and output of kelp in my country have been ranking first in the world. At present, kelp has become one of the two common edible seaweeds for coastal and inland people, and has outstanding advantages such as long storage period, convenient meal processing, and balanced nutrition. In 2019, the total number of kelp seed breeding in my country reached 37 billion , The aquaculture area is 44,000 hectares, and the total aquaculture output reaches 1.624 million tons. [0003] my country began to cultivate kelp since the 1950s. Since the artificial raft culture of kelp was carried out, autumn seedlings, summer seedlings, early autumn seedlings, summer seedlings, spring seedlings and two-y...

Problems solved by technology

[0008] The applicant encountered many problems in the process of research and development, among which there are two biggest difficulties: one is the problem of planting kelp, the spores for breeding winter seedlings of kelp are provided by kelp, and the sporangia on kelp generally cannot persist until It has already ruptured in December and released spores. How to delay the maturation of the sporangia on the kelp until December, and then collect the spores is an important difficulty; Under the premise of ensuring the survival rate and disease rot rate, it is also an important difficulty to breed kelp winter seedlings that meet the requirements.
