Embodiment 1

[0033] See attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 , attached Figure 5 , attached Figure 6 And attached Figure 7 , what the present invention provides is a kind of kelp and laver three-dimensional cultivation device, this kelp and laver three-dimensional cultivation device is a device for simultaneous co-cultivation of kelp and laver, and realizes the three-dimensional cultivation of kelp and laver. The three-dimensional culture device comprises kelp raft frame 10 and laver net 30, and kelp raft frame 10 is two and is arranged in parallel, with figure 1 Among them, the two kelp rafts 10 are arranged at two positions on the left and the right respectively, and two floating ropes 20 arranged in parallel are arranged between the two kelp rafts 10, and the floating ropes 20 and the kelp rafts 10 are usually It is vertically arranged, and the two floating ropes 20 are respectively arranged at two positions of the front side and the r...

Embodiment 2

[0040] A kind of kelp and seaweed three-dimensional cultivation method of the present invention comprises the following steps:

[0041] 1) Harvest seedlings in advance

[0042] At present, the main breeding areas of Porphyra variegata are in Jiangsu and Zhejiang, and the seaweed seedling nets start to be released into the sea in early October; the North Yellow Sea is in late September, and the water temperature drops and remains below 23°C. At this time, it is suitable for seedlings to be released into the sea. Seedlings were collected about 10-15 days in advance in Zhejiang area;

[0043] The method of picking seedlings in advance: the time for picking fruit spores to grow vegetables on the shells is the same as that in the south. From May, the fruit spores develop into filaments. After experiencing high temperatures in August, the algae filaments on the shells gradually expand and double spores appear. Start to form conchospores; in order to harvest seedlings in advance, us...

Abstract

The invention provides a three-dimensional breeding device and breeding method of kelp and laver. The three-dimensional breeding device comprises kelp raft frames and a laver net, wherein a floating rope is arranged on each kelp raft frame, a kelp seedling rope is arranged between every two floating ropes, and the kelp seedling rope is located at the bottom of each floating rope; and the laver netis arranged between the floating rope and located above the kelp seedling rope, a surrounding rope is arranged in the circumferential direction of the laver net, two ends of a short edge of the surrounding rope are respectively and detachably connected with the floating ropes, snap rings are further arranged on the long edge of the surrounding rope, and clips adaptive to the snap rings are arranged on the floating ropes. The invention also provides a method for performing three-dimensional breeding on kelp and laver through the breeding device. According to the three-dimensional breeding device and method disclosed by the invention, the kelp is at lower parts, the laver is at upper parts, three-dimensional breeding of the kelp and the laver is realized, bamboo poles and large cylindricalfloats are not needed, accumulation of floating horner sargassum frond is avoided, the laver is high in growth speed, good in quality and high in yield, the kelp is flourishing in growth, the resources are effectively utilized, seawater environment pollution caused by spilling of dilute hydrochloric acid on the sea surfaces is avoided, and the three-dimensional breeding device is simple in structure, convenient to manage and good in economic benefits.

Description

technical field [0001] The invention relates to the technical field of seaweed cultivation, in particular to a three-dimensional cultivation device for seaweed and seaweed and a cultivation method thereof. Background technique [0002] At present, the types of economic seaweed farming in Shandong Province mainly include kelp, wakame, asparagus and laver. Among them, kelp is the main cultured seaweed species in Shandong Province, with a total output of 533,000 tons, accounting for 82.5% of the total seaweed culture in the province. The area of ​​seaweed culture in Shandong Province is 18,397 hectares; however, the area of ​​laver culture in Shandong Province is relatively low, only There are 2978 hectares. [0003] Kelp is a vegetable with high nutritional value. At the same time, it has certain medicinal value. It is a large marine brown algae plant that grows in low-temperature seawater. During the growth of kelp, it can absorb nutrients such as nitrogen and phosphorus in ...
