Method for evaluating and comparing unit fresh/dry weight yield and water content of cultured sargassum fusiforme primary product

Abstract

The invention provides a method for evaluating and comparing the unit fresh / dry weight yield and the water content of a cultured sargassum fusiforme primary product. The method is characterized by comprising the following seven steps of counting the seedling clamping ropes and measuring the length, cleaning and removing the impurity, evaluating the parameters, calculating the unit fresh / dry weightyield (kg), calculating the fresh weight water content mass, comparing the unit fresh / dry weight yield (kg) difference, comparing the unit dry weight water content (%) difference and the like. According to the invention, a scientific evaluation and comparison method can be provided for the unit yield of the cultured sargassum fusiforme, and according to the method, the technical characteristics between the unit yield evaluation and difference comparison of the same strain, the same culture sea area, different growth times, the same strain, different culture sea areas, the same growth time, different strains, the same culture sea area, the same growth time or different strains, different culture sea areas and the same growth time of the cultured sargassum fusiforme are highlighted.

Description

technical field [0001] The invention relates to a method for evaluating and comparing fresh / dry weight yield per unit and water content of primary products of cultured Hijiki, highlighting the new method for scientific evaluation and comparison of fresh / dry weight yield and water content per unit of primary products of cultured Hijiki . Background technique [0002] Sargassum fusiforme belongs to Phaeophyta, Cyclospreae, Fucales, Sargassaceae, Sargassum, and is a large perennial species endemic to the Pacific Northwest coast. brown algae. Dongtou District, Wenzhou City, Zhejiang Province is the largest hijiki industry 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. From September to December every year, the seedlings are artificially planted in batches, and they are harvested from mid-April to mid-May of the following year. [0003] In recent years, the evaluation and statistics of...

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
