A method and device for naturally promoting maturation and sowing of subtidal eelgrass reproductive plants

Abstract

The invention relates to a sea grass land restoration and reconstruction technology and particularly relates to a natural ripening accelerating and sowing method and device for a subtidal eelgrass reproductive plant. The method comprises the steps of clamping an eelgrass reproductive plant on a natural sea grass land onto a main rope and a side rope of a device, and then, putting the device for fixing the eelgrass reproductive plant into a proper natural sea area to carry out natural ripening accelerating and sowing on the eelgrass reproductive plant, wherein the device is sequentially provided with a floating ball, the main rope and a dropstone from top to bottom, the floating ball and the dropstone are respectively arranged at two ends of the main rope, and the main rope of which one end is provided with the floating ball is provided with the side rope along the length direction. By using the natural ripening accelerating and sowing method and device, an eelgrass seed can ripen and naturally drop, so that the collecting problem that the eelgrass seed does not ripen or the ripened seed drops is solved, and the sowing difficulty of seabed sea grass in a relatively deep subtidal water area is also overcome; by combining the simple, convenient and effective eelgrass sowing method, an eelgrass sea grass land in the relatively deep subtidal water area can be conveniently and rapidly restored or reconstructed; and meanwhile the device disclosed by the invention can be recycled, so that the cost can be reduced, and the used material cannot pollute the sea area.

Description

technical field [0001] The invention relates to seagrass field recovery and reconstruction technology, in particular to a method and device for naturally promoting maturation and sowing of subtidal eelgrass reproductive plants. Background technique [0002] Seagrass meadows ecosystem, mangrove forest and coral reef ecosystem are considered to be three typical offshore marine ecosystems. And international research results show that the ecological service value of seagrass fields is significantly higher than that of mangroves and coral reefs. The "seaweed" mentioned here refers to the only angiosperm submerged in shallow sea water, which differentiates into organs such as roots, stems, leaves, flowers and seeds, and "seaweed" as lower plants (such as kelp, enteromorpha, etc.) very different. [0003] Lush seagrass fields are like forests on land, an important symbol of a healthy marine environment, and are precious "undersea grasslands" or "undersea forests". Seagrass field...

AI Technical Summary

Problems solved by technology

In the natural state, eelgrass seeds mature for a long period of time, first mature and fall off, and then fall off after maturity, so it is quite difficult to collect naturally mature seeds

At present, there is the problem of collecting eelgrass seeds that are immature or mature seeds have fallen off. In addition, the technology for sowing large areas of seaweed in deep waters in the subtidal zone is still weak, and there is a lack of simple and effective sowing methods.
