Embodiment 1

[0023] As an embodiment of the present invention, the hijiki quality breeding method comprises the following steps:

[0024] 1) Screening vegetables

[0025] Before carrying out sexual reproduction and artificial breeding of hijiki, the first thing to do is to sort out and plan the vegetable field, usually in March every year, when the hijiki algae are in the early stage of rapid growth and development, and the labor intensity is relatively small. The work of sorting out the vegetable field is mainly to increase the distance between the ropes of the seedlings stocked in the early stage. It is better to keep the distance between the ropes at about 3 meters, so as to create an excellent nutritional environment and light conditions for the growth and development of the vegetables.

[0026] When Sargassum enters the mature stage in mid-May, select the algae with strong plants, large individuals, and more air sacs as vegetables to remove the stunted growth of the algae and irregula...

Embodiment 2

[0045] As yet another embodiment of the present invention, the hijiki quality breeding method comprises the following steps:

[0046] 1) Screening vegetables

[0047] Before carrying out sexual reproduction and artificial breeding of hijiki, the first thing to do is to sort out and plan the vegetable field, usually in March every year, when the hijiki algae are in the early stage of rapid growth and development, and the labor intensity is relatively small. The work of sorting out the vegetable field is mainly to increase the distance between the ropes of the seedlings stocked in the early stage. It is better to keep the distance between the ropes at about 3.2 meters, so as to create an excellent nutritional environment and light conditions for the growth and development of the vegetables.

Embodiment 3

[0067] As another embodiment of the present invention, the hijiki quality breeding method comprises the following steps:

[0068] 1) Screening vegetables

[0069] Before carrying out sexual reproduction and artificial breeding of hijiki, the first thing to do is to sort out and plan the vegetable field, usually in March every year, when the hijiki algae are in the early stage of rapid growth and development, and the labor intensity is relatively small. The work of sorting out the vegetable field is mainly to increase the distance between the ropes of the seedlings stocked in the early stage. It is advisable to keep the distance between the ropes at about 2.8 meters, so as to create an excellent nutritional environment and light conditions for the growth and development of the vegetables.

[0070] When Sargassum enters the mature stage in mid-May, select the algae with strong plants, large individuals, and more air sacs as vegetables to remove the stunted growth of the algae an...

Abstract

The invention discloses a quality breeding method for sargassum fusiforme. The method comprises the steps that 1, ripe sargassum fusiforme alga bodies are selected to serve as main weeds, the quality ingredients of the main weeds are determined, and the main weeds of which the quality ingredients are in accordance with the following requirements are selected for seedling culturing, wherein the polysaccharide content, by dry weight, of the main weeds is larger than or equal to 40%, and the proportion sum of fucose, guluronic acid and mannuronic acid is larger than or equal to 80% by dry weight of the polysaccharide content of the sargassum fusiforme; 2, after the main weeds which are in accordance with the quality requirements are collected, lower alga bodies of the main weeds are removed, upper and middle alga bodies are retained, a female plant and a male plant are combined into a pair and put in a seedling culturing pool to be cultured for five to eight days, sperms and eggs are released and fertilized to form young embryos, and the young embryos are collected. According to the quality breeding method for the sargassum fusiforme, the breeding effect of the sargassum fusiforme can be significantly improved, the sargassum fusiforme obtained through the breeding method is more uniform in quality and good in breeding effect, the main weeds can be randomly selected for breeding, and the breeding quality of the main weeds is stable.

Description

technical field [0001] The invention relates to the technical field of hijiki cultivation, in particular to a hijiki quality breeding method. Background technique [0002] Sargassumfusiforme (Sargassumfusiforme or Hizikiafusiformis) belongs to Phaeophyta, Sargassaceae (Sargassaceae), and Sargassum genus. It is a perennial large brown algae unique to the coastal waters of the Northwest Pacific Ocean. Sea vegetables and traditional delicacies in the coastal areas of China, South Korea and North Korea have a long history of edible and medicinal use. Wenzhou Dongtou and Pingyang are the main places for breeding and processing hijiki in my country, and the products are mainly exported to Japan and South Korea. Although my country's cultured Hijiki has an advantage in production, its quality is at a disadvantage compared with Japan and South Korea, and the export price is suppressed, which seriously affects production efficiency. Contents of the invention [0003] In view of t...
