Description

A kind of medium strip structure and components that can improve the seedling attachment rate of hijiki

technical field

The present invention relates to a culture medium strip structure capable of increasing the seedling attachment rate of Hijiki, and also relates to the components of the culture medium strip, which is suitable for the artificial use of Hijiki for sexual reproduction seedling breeding agriculture Production and production of medium with high seedling rate in the fields of production and strain classification and storage, scientific research and production.

Background technique

Sargassum hijiki is a unique edible and medicinal brown algae in the coastal waters of the Pacific Northwest, which has two life histories of sexual reproduction and asexual reproduction. Due to the characteristics of high production efficiency and good uniformity of seedlings by artificially using hijiki for sexual reproduction and breeding seedlings, it has become the main source of seedlings for agricultural production. my country is the first country to use hijiki for sexual reproduction and breeding seedlings. It emerged in the mid-1990s, and now this technology has been widely used in agricultural production.

In the process of artificially utilizing hijiki for sexual reproduction and seedling development, people have tried to use plastic plates, glass plates, sacks, and bamboo curtains as the medium for fertilized eggs of hijiki, but due to high production costs and easy loss , weak tensile strength or inconvenient disassembly, etc., have not been widely used in agricultural production. After continuous improvement, the sheet-like seedling curtain sewn from cloth strips has become the main culture medium and has been promoted. application. At present, due to design defects such as weaving material structure ratio and seedling surface structure, sheet-like attached seedling curtains sewn by cloth strips often appear, and the rate of fertilized seedlings attached to seedlings is too low or completely impossible to attach seedlings due to excessive cloth strips.

In the field management in sea areas, because the cloth strips are easy to adhere to the sediment, which affects the photosynthesis of the young embryos or young sporophytes of Hijiki, resulting in stunted or dead seedlings. Therefore, the existing field management technology mainly uses high-pressure water guns to Flushing eliminates the negative impact of attached sediment on immature embryos or immature sporophytes. The medium needs to be flushed with a high-pressure water gun once every other day, often resulting in a large loss of immature embryos or immature sporophytes due to excessive jet water pressure; A large number of seedling curtains are broken; due to long-term stocking in sea areas, harmful organisms are fixed on the back of the cloth strips, causing the culture medium to sink deeper into the water layer, which slows down the development of young sporophytes; due to the classification and purification of strains, the single structure of the seedling curtains is easy to cause artificial Mixed and other issues, the above-mentioned problems have not been effectively resolved in actual production. The patent of the present invention is based on the above-mentioned problems, and through scientific planning and design, a medium cloth strip with a high seedling attachment rate of Hijiki has been invented, which can effectively solve the problems of low seedling attachment rate, loss of young sporophytes, weak tensile strength, and There are problems such as the classification and cultivation of different strains due to the different structure of the attached seedling surface of the medium, and the improvement of the labor efficiency of manual removal of attached harmful organisms.

The attachment of the rhizoid filaments, located around the growth part, forms a raised protective part that is higher than the surface of the growth part and protects it.

In this embodiment, the protruding protective portion of the protective layer can be in various structural forms, so as to combine different structural forms of the growing portion.

Embodiment 1: As shown in Figure 2 and Figure 3, the raised protection part 131 and the growing part 121 are distributed in a square grid shape on the strip body 1, and the width of the strip body 1: 20 mm; thickness: 1.0 mm; the side length of the square grid shape is 1.0 mm, the height of the raised protection part 131 is 0.3 mm; the thickness of the adhesion layer 12 (the insertion part 121 ) is 0.5 mm; the thickness of the bottom layer 11 is 0.2 mm. In this solution, the protruding protection part 131 is located around the growth part 121 and is higher than the growth part 121. When receiving an external impact, it can protect the growth of Hijiki in different periods on the growth part 121. The growth part 121 and the protruding protection part 131 are evenly distributed. Such a cloth strip body 1 structure can facilitate statistical calculation and check the uniformity of the growing part 121, so that it is suitable for scientific research and practical teaching.

Embodiment 2: As shown in Fig. 4 to Fig. 5, the raised protection parts 131a are arranged laterally in the width direction of the cloth strip body 1, and several adjacent raised protection parts 131a are formed between them. The protruding protection sub-sections 132a arranged longitudinally, the growing part 121a is formed between adjacent protruding protection sub-sections 132a, the height of the protruding protection part 131a is higher than the setting of the protruding protection sub-sections 132a, in this embodiment, The raised protection part 131a can provide stronger impact resistance than the raised protection subsection 132a, and the combination of the two can have a better impact resistance effect. In this embodiment, the width of the strip body 1: 20mm; the thickness: 1.0mm; the width and the height of the raised protection portion 131a are 1mm and the distance between the adjacent raised protection portions 131a is 1.5mm, the width of the raised protective portion 132a is 1mm, and the height of the raised protection portion 132a is 0.5mm, adjacent The interval between the raised protection subsections 132a is 0.5mm.

Embodiment 3: As shown in Figures 6 to 7, the raised protection part 131b is arranged laterally in the width direction of the strip body and its cross-section is a trapezoidal structure with a small top and a large bottom, and the adjacent raised protection parts Between 131b, a number of protruding protection subsections 132b are formed which are connected to both and arranged longitudinally. The area is convenient for the fixed attachment of the rhizome of Sargassum sargassum, and the growth part 121b is formed between the adjacent raised protection subsections 132b, and the height of the raised protection section 131b is higher than that of the raised protection section 132b. In this embodiment, Among them, the protruding protective portion 131b of trapezoidal structure has inclined surfaces capable of providing buffering on both sides, so that the protective layer 13 has a better impact resistance effect, and has a better impact resistance effect compared with Embodiment 2. In this embodiment , cloth strip body 1 width: 20mm; thickness: 1.0mm; dimensions of the raised protection part 131b: the width of the upper bottom is 1mm, the width of the lower bottom is 2mm, the height is 1mm and the distance between adjacent raised protection parts 131b is the upper bottom The width of the lower bottom is 1mm, the width of the raised protection subsection 132b is 1mm, the height is 0.5mm, the interval between adjacent raised protection subsections 132b is 0.3mm, and the thickness of the bottom surface is 0.2mm.

In the above-mentioned embodiment, the setting of the bottom layer 11 and the protective layer 13 can make the strip body have a certain structural strength, so as to adapt to the impact of wind and waves on the medium cloth strip. At the same time, the protective layer 13 is provided with a raised protective part, The protruding protective part can protect Hijiki in different periods on the peristaltic part, especially the fixation of fertilized egg rhizoid filaments and young sporophytic rhizomes, avoiding the impact of excessive water flow from the outside, And caused the loss of hijiki seedlings (immature embryo or immature sporophyte state). The cloth strip body 1 has a single-sided structure, that is, the back is the back of the bottom layer 11, and the back is easy and convenient to remove the fixed enemy organisms.

The present invention also discloses the components of the medium cloth strip, which is characterized in that: the components of the bottom layer 11, the adhesion layer 12 and the protective layer 13 of the medium cloth strip are as follows,
