Embodiment 1
[0036] A kind of indoor long-term culturing method of eel algae seedlings, the steps are:
[0037] (1) Expose the newly excavated bottom mud of the sea area where the eelweed grows to the sun for 2-3 days under strong light to sterilize, and then place it at the bottom of a plastic flowerpot with a diameter of 10cm, about 10-15cm thick, and the bottom of the flowerpot is marked with a diameter 4 holes with a diameter of 1 cm, and 8 holes with a diameter of 1 cm on the side, so that the seawater can flow through the bottom mud. outflow;
[0038] (2) In late April, dig out the newly released cloned seedlings of Zorophyllum or the seedlings that germinated in the same year (plant height about 15cm), bring them back to the laboratory as soon as possible together with a small amount of sediment, and plant them in the above-mentioned plastic flower pots , only one plant is planted in each flower pot, and a total of 15 plants are planted;
[0039] (3) Put the flower pot into the aq...

Abstract
The invention relates to the field of seaweed life, physiological, and ecological habit study. The invention relates to a zostera marina indoor long-term cultivation method and a device for realizing the method. The cultivation device is composed of four parts which are an aquarium, a lighting system, a circulation filtration system and a water temperature regulation system. The cultivation method comprises the following steps: zostera marina is planted in a plastic pot with sediment mud sterilized by sunlight exposure; The pot is placed in the aquarium, and fresh sea water is added, wherein the water level of the sea water is higher by 10cm than the top of the zostera marina plant; a water circulation condition is twice/h, a lighting condition is 12h light/12h dark and 5000lux, a water temperature is 10-25 DEG C, 1/3 of the sea water is replaced every month, and a salinity is 3-3.7%; impurities on the inner wall of the aquarium are removed regularly; and the sediment mud is replaced according to plant growth conditions. If the physiological functions of zostera marina are to be studied, light intensity, water temperature and sea water salinity can be adjusted according to needs, and nutrients can be added to the small pot. The method and the device provided by the invention are suitable for the cultivation of zostera marina in scientific researches, such that life habits, physiological characteristics and ecological characteristics of zostera marina can be studied.
Description
technical field [0001] The invention belongs to the field of seaweed life, physiology, and ecological habit research. The invention relates to a method and device for indoor long-term cultivation of eel algae, which is suitable for cultivating eel algae in scientific research to study its living habits, physiological characteristics and ecological characteristics. [0002] Background technique [0003] Eelweed ( Zostera marina L.) is a marine monocot belonging to the genus Zosteraceae (Zosteraceae) ( Zostera ), are widely distributed in the shallow waters from the low tidal zone to the subtidal zone along the northern coast of my country (Shandong, Hebei and Liaoning), and mostly form single-quality seagrass fields, which have extremely important ecological service functions and economic value. However, in the past two decades, due to human factors such as pollution in offshore waters, the ecosystem of eelgrass seagrass in my country has been severely damaged, and the ar...
