Problems solved by technology

However, due to the relatively long cultivation time in summer, there are many influencing factors, such as the destructive effect of the basket fish; the basket fish generally appear in high temperature periods, bite the rhizoids and their seedlings, resulting in The seedling survival rate is low, so it cannot fully meet the seedling needs of artificial breeding

Embodiment 1

[0035] (1), build the shape of the seedling raising device: in the middle and early June, select four fixed points in the sea area with smooth water flow in Rizhao, nail the four positioning piles 1 on the fixed points, and the positioning cable 3 is connected to the positioning pile through the pile cable 2 to form square structure;

[0036](2) Construct a three-dimensional "V"-shaped grid structure: on the positioning cable, fix multiple cables in parallel along the direction of the tide, and install a position control cable in parallel between every two cables; There are floating balls on the surface of the water body, and the falling rocks are distributed on the position control cables in the middle and lower layers of the water body. The floating cables and position control cables are arranged alternately to form a three-dimensional "V" shape;

[0037] (3), attaching seedlings: the seedling rope is sterilized by soaking in seawater for 24 hours, and then the rhizome of Hi...

Embodiment 2

[0041] The method is the same as in Example 1, except that the sea area is the coastal sea area of ​​Qingdao, and when the culture reaches the end of October, the rhizoids on the seedling ropes give birth to young shoots, and the seedling attachment rate of the seedlings reaches 91%, which is much higher than that of traditional culture. 58-76% of technology.

Abstract

The invention discloses a sargassum fusiforme rhizoid summer-cross seedling-raising device comprising positioning piles, pile cables and positioning cables. The positioning piles are fixed on four points, the positioning cables are connected on the positioning piles through the pile cables, such that a square structure is formed; rope cables are fixed on the positioning cables; a position-control cable is arranged in parallel between each two rope cables; and the rope cables and the position-control cables are arranged in a same direction with tides. Float balls are tied on the rope cables, such that the rope cables are positioned on surface water; weights are tied on the position-control cables, such that the position-control cables are positioned in shallow water. Therefore, stereo V shapes are formed. Two ends of seedling ropes are respectively tied on the rope cables and the position-control cables, wherein an included angle formed by two seedling ropes is 135-150 DEG. When the device is used for raising seedling, the seedling ropes are in stereo V shapes, and are distributed in different water levels, such that a well-spaced layout is formed, and the damage caused by siganus which is regularly active in a same water level can be effectively prevented. With the device, a stereo grid structure is established, and siganus damages can be prevented. Under the impact of wind and waves, stable culturing facility and structure can be maintained, and seedling growth and maintenance time can be ensured.

Description

technical field [0001] The present invention relates to a device and method for cultivating seedlings with rhizomes of hijiki in summer, in particular to a device and method for raising seedlings by using rhizomes in summer and cultivating seedlings by leaving rhizomes after harvesting hijiki, which belongs to seaweed The field of proliferating technology. Background technique [0002] Hijiki is an important economic seaweed that is exported to earn foreign exchange in the southeastern coastal areas of my country. It is a large-scale cultivated species after laver, kelp, wakame and asparagus. In addition to being used as seaweed food, Hijiki contains anti-tumor active substances, which can stimulate the immune system. It is a potentially important raw material algae for marine medicines. It is also rich in antioxidants such as polyphenols and fucoxanthin. substance. At present, there are three main sources of seedlings of Hijiki: collecting wild natural seedlings, artifici...
