Problems solved by technology

Although halograss has a strong clonal growth ability, due to the constraints of the marine environment, and the fact that seagrass grows in the subtidal zone and is submerged in seawater most of the time, it is very difficult to collect seeds, which makes the protection and restorati

Embodiment 1

[0022] A method for artificially cultivating salt-loving grass seedlings for marine ecological restoration, comprising the steps of:

[0023] (1) The source and selection of the seedlings of Salt-loving Grass: After the sea area where the Salt-loving Grass grows ebbs, select the Salt-loving Grass with thicker and longer stolons, lush leaves, and bud tips on the stem nodes from the subtidal zone of the sea area , after collecting back, wash off the silt and sundries attached to it with fresh sea water, and cut the stolons into several small sections for cultivation. The length and specifications of each small section of stolons are as follows: each small section of stolons has 2 to 3 Stem nodes, with leaves and bud tips growing on the stem nodes, with a length of 3 cm;

[0024] (2) Cultivation conditions for the seedlings of Saltophilus: choose a white storage box with a capacity of 145L, clean and disinfect, add 120L of filtered fresh seawater, and add 120L of filtered fresh s...

Embodiment 2

[0031] A method for artificially cultivating salt-loving grass seedlings for marine ecological restoration, comprising the steps of:

[0032] (1) The source and selection of the seedlings of Salt-loving Grass: After the sea area where the Salt-loving Grass grows ebbs, select the Salt-loving Grass with thicker and longer stolons, luxuriant leaves, and bud tips on the stem nodes from the subtidal zone of the sea area , after collecting back, wash off the silt and sundries attached to it with fresh sea water, and cut the stolons into several small sections for cultivation. The length and specifications of each small section of stolons are as follows: each small section of stolons has 2 to 3 Stem nodes, with leaves and bud tips growing on the stem nodes, with a length of 4cm;

[0033] (2) Cultivation conditions for the seedlings of Saltophilus: choose a white storage box with a capacity of 165L, clean and disinfect, add 130L of filtered fresh seawater, and add 130L of filtered fre...

Abstract

The invention relates to an artificial culture method of halophila oralis seedlings for marine ecological restoration, and belongs to the technical field of artificial culture of marine plant seedlings. According to the method, halophila oralis is cultured indoors to quickly obtain high-quality seedlings according to the reproduction characteristics that stem nodes on creeping stems of the halophila oralis can meristem and bifurcate and the creeping stems can horizontally extend and grow; the method specifically comprises the step of placing pruned creeping stem sections in seawater in which nutrient solution and a plant growth promotion hormone are added to culture for 25-30 days until the creeping stems extend horizontally to newly increase 2-3 stem nodes. The method has the characteristics of simple required equipment, convenience in material source, low production cost, easiness in mastering of the technology, horizontal extension of the creeping stems and high growth speed of buds on the stem nodes, the defect that the growth and the reproduction of the halophila oralis are affected by natural factors can be overcome, a large number of halophila oralis seedlings can be quickly obtained, the growth speed is high after the seedlings are transplanted to a sea area, and the protection and restoration effects on the halophila oralis are obvious.

Description

technical field [0001] The present invention relates to an artificial cultivation method for seedlings, in particular to an artificial cultivation method for seaweed seedlings used for marine ecological restoration, a method for artificial cultivation of seaweed seedlings grown in subtidal zones, especially a The invention relates to a method for artificially cultivating the stolons of the seaweed that has the function of repairing the marine ecological environment and purifying the water quality, and belongs to the technical field of artificial cultivation of marine plant seedlings. Background technique [0002] Seagrass is a kind of monocotyledonous herbaceous plant that lives in shallow water along the coast of temperate seas. It generally grows in the coastal subtidal zone. In tropical and tropical coastal areas, vast seagrass fields are often formed. Seagrass beds are the same as mangroves and coral reefs. In a typical marine ecosystem, the seagrass bed composed of seag...
