Problems solved by technology

[0006] In order to overcome the low efficiency of planting vegetables in the process of picking seedlings in the prior art and the phenomenon of wasteful use of planting vegetables, the present invention provides a method for picking seedlings of Sargassum and its early cultivation method. The method for picking seedlings specifically includes collecting vegetables 1. Vegetable pretreatment, seedling pond layout and seedling collection four steps. In this method, through shade drying and accurate control of seedling collection conditions, the precise seedling collection of vegetable seedlings can be achieved, and at the same time, the dispersal efficiency of vegetable seedlings can be greatly improved. At the same time, this method The invention also greatly improves the reproductive efficiency of Sargassum by controlling the early cultivation conditions, so the present invention is very suitable for popularization and application in the field of artificial propagation of Sargassum

Embodiment 1

[0034] Example 1 The seedling picking method and cultivation method of Sargassum of the present invention

[0035] A method for picking seedlings of Sargassum and a cultivation method thereof, which specifically comprises the steps of:

[0036] (1) Vegetable collection: When collecting sargassum to grow vegetables, the selected algae must meet the following conditions at the same time:

[0037] a. Female individuals whose algal body length is greater than 80 cm;

[0038] b. The average length of reproductive branches is not less than 5cm;

[0039] c. The reproductive receptacle is mature and the length of the reproductive receptacle is not less than 5mm;

[0040] d. Obvious egg attachment phenomenon on the genital receptacle.

[0041] (2) Vegetable pretreatment: After the vegetables are collected, put them in a transfer box with holes at the bottom to drain the seawater, and place them under low light conditions (light less than 2000lx) for 30 minutes to dry in the sha...

Abstract

The invention relates to a seedling collecting method and early breeding method of sargassum thunbergii, and belongs to the field of seaweed artificial breeding. By means of the seedling collecting method and early breeding method of sargassum thunbergii, the phenomena that in the seedling collecting process in the prior art, the diffusing efficiency of seed seedlings is low, and using of seed seedlings is waste are avoided. The seedling collecting method specially includes the five steps of seed seedling collecting, seed seedling pretreating, seedling collecting pond laying, seedling collecting and early breeding. Due to drying-in-the-shade treatment and seedling-collecting-condition accurate controlling, accurate seedling collecting is achieved, and meanwhile the diffusing efficiency of seed seedlings can be greatly improved; meanwhile, the breeding efficiency of sargassum thunbergii is greatly improved by controlling the early breeding condition, and the seedling collecting method and early breeding method are quite suitable for applying and popularizing in the field of sargassum-thunbergii artificial breeding.

Description

technical field [0001] The invention relates to a method for collecting seedlings of sargassum and an early cultivation method thereof, belonging to the field of seaweed artificial breeding. Background technique [0002] Sargassum is a species of brown algae with economic value. It can not only be used as high-quality feed for sea cucumbers, abalones and other sea treasures, but also can be used as industrial raw materials to extract alginate and other biologically active substances. In recent years, Sargassum resources have been severely affected by human activities, and artificial breeding of Sargassum has become an important way to alleviate and restore related ecological problems. At present, the artificial breeding technology system of Sargassum has been initially established, but many key parameters of seedling production need to be further optimized. [0003] At present, there are two ways of collecting seedlings of Sargassum seedlings: full manual seedling picking a...
