Embodiment 2

[0023] Embodiment 2, the differences between this embodiment and Embodiment 1 are:

[0024] In step (1), keep dark, seal and hypoxia, and culture at 4°C for 30 days;

[0025] In step (2), keep the light 4500lx, aerobic, and culture at 10°C for 5 days;

[0026] In step (3), keep the culture under the conditions of 2500lx light, aerobic, and 15°C for 7 days.

[0027] In this embodiment, the germination rate and germination speed of the seeds can also be improved within 2% of the distortion rate during the germination process.

Embodiment 3

[0028] Embodiment 3, the differences between this embodiment and Embodiment 1 are:

[0029] In step (1), keep dark, seal and hypoxia, and culture at 4°C for 40 days;

[0030] In step (2), keep the light 4800lx, aerobic, and culture at 10°C for 6 days;

[0031] In step (3), the culture is maintained for 10 days under the conditions of light of 2500 lx, aerobic, and temperature of 15°C.

[0032] The seedlings cultivated in this embodiment have fast development speed, strong plants, low deformity rate and high seedling rate, and can be quickly applied to seagrass field reconstruction.

Abstract

To solve the problem that distortion can be easily caused in a seed germination process when an existing low salt stimulus method is used to cultivate zostera marina, the invention provides a cultivation method of zostera marina high-quality seedling plants. According to different development stages in the germination process of seeds of the zostera marina, different cultivation conditions are procedurally regulated, invade and harass of mildew and mussy algae in the seed germination process can be reduced, and the shortcoming that the distortion can be easily caused in the seed germination process by using of traditional seedling plant obtaining method is overcome to a certain degree. The zostera marina is cultivated by adoption of the method, germination time of the seeds of the zostera marina can be shortened, a germination rate can be improved by 30%-40%, a growing length of cotyledons can be remarkably increased by 2-3 times, a distortion rate of the seeds in the germination process is controlled within 2%, the cultivated cotyledons of seedlings are thick and solid and outstretched, plants are robust, and a growth rate is quick.

Description

technical field [0001] The invention relates to a method for cultivating high-quality seedlings of eelgrass by using seeds. Background technique [0002] Zoster belongs to the order Helobiae, the family Zosteraceae, and the genus Zostera. As a typical representative of seagrass, eelgrass contributes to coastal marine ecosystems around the world by forming vast seagrass beds in shallow sea areas. a wide range of applications. Studies have found that transplanting eelgrass in the culture pond is beneficial to the increase of the yield of prawns and sea cucumbers, and the seeds of eelgrass and various organisms attached to its leaves can be used as bait for marine economic species. Unfortunately, including our country, the resources of eel algae are seriously degraded worldwide. The use of seeds to restore the population of Zinnia not only has the advantages of low cost and simple operation, but also maintains the genetic diversity of the population to the greatest extent, a...
