Algae reproduction device with seedling protecting function

Abstract

The invention discloses an algae reproduction device with the seedling protecting function. The algae reproduction device with the seedling protecting function aims to overcome the defect that due to the fact that an artificial algae reproduction facility in the prior art can not protect algae seedlings sufficiently, the reproduction rate of algae is low. The algae reproduction device comprises a floater, a hanging rope, a cultivation body and a locating anchor. The cultivation body comprises a circular-ring-shaped upper frame, a base plate, a middle column, a silica gel base body of a conical surface shape, a balancing weight and algal reef bricks. The edge of the wider end of the conical structure of the silica gel base body is fixedly connected to the upper frame, and the edge of the narrower end is fixedly connected with the edge of the base plate. The algal reef bricks are laid on the surface of the inner side of the silica gel base body. The floater is connected to the top end of the middle column through the hanging rope. The bottom end of the middle column is connected with the locating anchor through the hanging rope. The algae reproduction device has the following advantages that the algae seedlings can be protected, the survival rate of the seedlings is increased, the growth space of the algae is expanded when the algae grows to a certain scale, and then the algae can be reproduced further; the yield of a unit cultivation area is easy to control, which is beneficial for industrialization of algae cultivation; when big waves invade, the algae sink automatically, and therefore loss of damage to the algae can be reduced.

Description

technical field [0001] The invention relates to an auxiliary device for aquatic plant cultivation, in particular to a device for increasing the output of seaweed cultivation. Background technique [0002] At present, coastal ecological environment problems are gradually attracting public attention. Due to overfishing and sewage discharge, the coastal ecological environment is damaged, which eventually leads to the deterioration of the coastal water environment and the decline of fish populations. The more effective remedial measures are to restore the offshore environment through artificial means. One of the means is to put artificial facilities in the offshore that can make seaweed multiply. Seaweed farms supported by large algae have high primary productivity and form complex dynamics. The plant food web can enrich eutrophic salts such as N and P, restrain the outbreak of "red tide", absorb heavy metal ions, and protect the marine environment. The artificially cultivated ...
