AI Technical Summary

Problems solved by technology

At present, the unit yield assessment of hijiki is generally calculated based on the average fresh species and dry weight of a single seedling rope, ignoring the evaluation parameters such as the actual unit area selection (sea mu or mu), the number of seedlings attached to a single seedling rope, and the total number of seedling ropes per unit area. , resulting in a large difference between the unit output evaluation value and the actual unit output value

Embodiment Construction

[0030] In order to reflect the purpose, technical solutions and innovative points of the present invention more clearly and comprehensibly, the present invention is further described in detail below with reference to specific implementation examples.

[0031] Implementation Example 1: Breeding of the same strain of hijiki, different growth times, and the same breeding sea area. In this example, the yield per unit of fresh / dry weight and the water content of the primary product of the artificially purified new strain of cultured hijiki are evaluated and compared.

[0032] As the first implementation example of the present invention, the fresh / dry weight yield and water content of primary products of different growth stages of the new strains of cultured hijiki that are suitable for artificial purification are evaluated and compared. / Dry weight yield and water content evaluation and comparison methods mainly include the following steps:

[0033] 1. Objectives and Background

Abstract

The present invention proposes a method for evaluating and comparing fresh / dry weight yield and moisture content per unit fresh / dry weight of primary products of cultured Hijiki, which is characterized by the following steps: counting and measuring the length of the clamping rope, cleaning and removing impurities, evaluating parameters, and unit fresh Calculation of yield / dry weight (kg), calculation of water content in fresh weight, comparison of unit fresh / dry weight yield (kg), comparison of unit dry weight moisture content (%) and other seven aspects. The present invention can provide a scientific evaluation and comparison method for the unit yield of cultured Hijiki. The method focuses on the same strain of cultured Hijiki, the same cultured sea area, different growth time, the same strain, different cultured sea area, the same growth time, different strains, The technical characteristics of the unit yield evaluation and difference comparison between the same cultured sea area, the same growth time or different strains, different cultured sea areas, and the same growth time.

Description

technical field [0001] The invention relates to a method for evaluating and comparing the yield per unit of fresh / dry weight and water content of the primary product of cultured hijiki, which highlights a new method for scientific evaluation and comparison of the yield per unit of fresh / dry weight and the water content of the primary product of cultured hijiki. . Background technique [0002] hijiki ( Sargassum fusiforme) It belongs to Phaeophyta, Cyclospreae, Fucales, Sargassaceae, and Sargassum. It is a perennial large brown algae unique to the Pacific Northwest coast. Dongtou District, Wenzhou City, Zhejiang Province is the largest hijiki industrial base in my country, with an annual planting area of ​​more than 11,000 mu. The main farming methods are soft raft and flat hanging farming. The seedlings are planted in batches from September to December every year, and harvested from mid-April to mid-May of the following year. [0003] In recent years, the evaluation and s...
