Abstract

The present invention provides a planting method for marine seeding, which can seed a seed in a wide range on the sea bottom without outflow of the seed and increase the germination rate, and a growth material, which is a granular material 30 obtained by mixing seeds of a plant, a cohesive soil containing dredged soil, and a solidified material mainly composed of gypsum and a water-soluble polymer. Anaerobic conditions suitable for seed germination can be maintained in the granular material and nutrients can be provided by sludge formation of dredged soil after germination, and since the seeds are covered with cohesive soil, they are not eaten by animals living on the seabed, ensuring survival rate.

Description

Planting mode and growth material for ocean seeding

Technical Field

The invention relates to a marine seed plant growth material, a production method of the marine plant growth material and a construction method of a marine plant growth field.

Background

Marine plants (marine plants) are autotrophic organisms in the ocean that use chlorophyll for photosynthesis to produce organic matter. Marine plants belong to the primary producers. There are many phyla of marine plants, 1 million in total, from lower eukaryotic nucleus-free algae (i.e., the cyanophyta and proto-chlorophyta of prokaryotic cells), to rhodophyta, phaeophyta and chlorophyta of eukaryotic cells, and to 13 phyla of higher-grade seed plants.

The marine plant resources in China are extremely rich, various wild plants grow on the seabed, and the high yield of the wild plants comprises seaweed, kelp, seaweed and the like. Algae are the most widely distributed organisms in the ocean, ranging from tiny unicellular organisms to giant kelp as long as several 10 meters. The marine algae in the world's oceans are about 10000 varieties. The algae contains algal polysaccharides, proteins, fats, vitamins, minerals and physiologically active substances with specific functions in 11 phyla such as Chlorophyta, Phaeophyta, Cyanophyta and Rhodophyta, and is a raw material library for food, feed and medicine. According to the algae morphology, the algae can be divided into macroalgae and microalgae. At present, people mainly utilize large-sized seaweeds such as kelp, undaria pinnatifida, kelp and kelp in brown algae comprehensively; carex chinensis and Ulva lactuca of green algae; the laver, agar, agaricus bisporus and the like in the red algae are only a small part 1 of seaweed resources, and the microalgae with huge reserves are raw material banks in which various physiological active substances are inexhaustible. The research and application of marine plants as livestock and poultry animal feed starts in the 50 th century, and China has not formed corresponding marine plant feed processing industry so far.

The marine plant is rich in nutrition, contains various bioactive substances, and has biological activities of enhancing immunity, resisting diseases and viruses, promoting growth, etc. The cultivation of marine plants can improve the ecological environment and protect aquatic organism resources. Therefore, the development of marine plant feed and the promotion of animal husbandry are receiving wide attention.

Disclosure of Invention

Disclosed herein is a planting method for marine seeding and a growing material according to the present invention, which is a granular material obtained by mixing cohesive soil and dredged soil containing marine plant seeds, a setting material mainly composed of gypsum, and a water-soluble polymer.

According to this marine plant breeding material, by mixing seeds with koji and granulating the material, a specific gravity greater than that of only the seeds (about 1.3) to about 2.3 can be made, and the possibility of being washed away is low. The seeds can be buried to a depth suitable for germination, and since the material can be made into a granular product having an outer diameter of about 3 to 20 mm, uniform sowing can be performed over a wide range. Furthermore, anaerobic conditions suitable for the germination of the seeds are maintained in the material, after which the dredged soil portion becomes turbid and provides nutrients until the seeds germinate by being clay-coated, the granular product being neutral and non-toxic and having no effect on the surrounding sea area. Marine seed plant seeds are fixed in the gaps between a solidified material mainly composed of gypsum and a granular product of cohesive soil of dredged soil containing a water-soluble polymer.

A method for producing a marine seed plant growth material is obtained by softening the above plant growth material into the sea, changing the hardness to an appropriate level before and after germination of the seed, and gelatinizing it after germination. In order to provide nutrients suitable for gel growth, the solidifying material and gelling agent are mixed taking into account the peripheral flow rate and the retention period of the particulate material or gel mixture.

In addition, by further mixing the above-mentioned at least one of sand and gravel with the marine plant growth material, it is possible to obtain the effects of preventing erosion and stabilizing bottom sediments in the marine plant growth ground, which becomes a support base for supporting the seed plants.

According to the method for producing a marine plant growth material of the present invention, by setting the amount of the solidifying material to be added, the growth material can be gelatinized after germination, and the germination rate of the seeds can be improved.

Drawings

Fig. 1 is a diagram of steps (a) to (c) of constructing a marine plant grassland using the plant growth material of the present embodiment.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

According to fig. 1, the plant cultivation material of the present example is prepared by mixing seeds, dredged soil (cohesive soil) and a gelling agent (additive) consisting of two liquids to form a gel. After the clay, the seeds and the gelling agent composed of two liquids are dredged to the inlet 41a of the pipe mixer 41 and mixed in the pipe mixer 41. The gelled mixture is supplied from the outlet 41 b. After hardening to a medium deformable hardness after about 30 minutes, the cementitious mixture 45 is sent to a placing vessel 42 and placed on the sea bed G of the seaweed forming site. Since the gelled mixture 45 is mixed with the dredged soil to form a gel, it is less likely to be washed away after being placed in the sea, and the gelled mixture 45 can be buried to a depth suitable for germination of the seeds. Furthermore, the seeds are wrapped in cohesive soil, so that they cannot be taken up by benthic animals before germination.

As shown in c, an anaerobic state suitable for germination of the seeds 29 is maintained in the gel mixture, and germination occurs. After germination of the seeds 29, the clay portion becomes a slurry to provide nutrients. As described above, the seeds are not discharged since they are covered with the dredged soil containing a suitable gel material, and can be maintained in an anaerobic state by the dredged soil. Furthermore, the gel mixture 45 can be decomposed at any time and does not hinder the growth after germination. The gel mixture is neutral and non-toxic and does not affect the surrounding sea area. In addition, the seeds are not exposed to the sand surface and do not accumulate floating mud.
