Description

A vertical seedling raising device for seaweed shell filaments

technical field

The utility model belongs to the technical field of laver cultivation, in particular to a vertical seedling cultivation device for laver shell filaments.

Background technique

Porphyra is the largest large-scale economic seaweed in my country. According to the statistics of "China Fishery Statistical Yearbook", it is about 900,000 mu. The types of laver cultivated in my country mainly include altar laver and zebra. The scale of altar laver cultivation is about 300,000 mu, and the scale of laver cultivation is about 600,000 mu. Altar laver is a warm-temperate species, mainly cultivated in Fujian and Zhejiang, and Guangdong also has a certain scale of cultivation. Porphyra zebra is a cold-temperate species, which is mainly cultivated in Jiangsu Province, and there is also small-scale cultivation in Rizhao, Shandong Province. Due to the warming of the climate, in recent years, algae laver has tried to move northward to Jiangsu Province for cultivation, and zebra laver has expanded its cultivation scale in Shandong and Dalian.

Laver seedlings in southern altars mostly adopt the hanging type, that is, shells are punched, stringed up with ropes, hung on bamboo poles, and cultivated vertically in seedling ponds. This method of raising seedlings can greatly save the area of the seedling room, but it has the disadvantage of serious uneven illumination, and the lower part is hardly illuminated. Therefore, it is necessary to regularly turn the shells up and down, the work is tedious and laborious, and it is still difficult to make the shells grow, develop, and mature synchronously. Porphyra zebra seedlings are raised in a flat way, that is, the shells are laid flat in the nursery pond, and the concave side is raised. Though this seedling raising method shell receives light evenly, can adopt the average seedling efficiency of 0.8-1 mu of seedling curtain according to 1 square meter of shell filaments, 600,000 mu of cultivation area then needs 600,000-750,000 square seedling rooms.

The utility model patent CN203492505U discloses a kind of intelligent supplementary light device for laver seedling room, which includes energy-saving lamp groups that can automatically adjust the light intensity installed above the seedling ponds. The energy-saving lamp groups that can automatically adjust the light intensity include several An energy-saving lamp that can automatically adjust the intensity of light. The energy-saving lamp that can automatically adjust the intensity of light is composed of a power supply device, an energy-saving lamp, a control device, a rectifier, a photometer, and a sliding rheostat. The energy-saving lamp that can automatically adjust the intensity of light Energy-saving lamps are evenly distributed above the seedling ponds. In this utility model, by setting uniform lighting parameters suitable for the cultivation of filaments by setting the energy-saving lamps installed above the seedling ponds that can automatically adjust the light intensity, the balance of lighting conditions for filaments can be achieved, which is more conducive to the growth of indoor filaments in seedling cultivation. The body grows in a balanced manner. But what this utility model adopts is to supplement the light at the top, which is only applicable to the Porphyra zebra that is raised horizontally. For the Porphyra filaments that are positioned at the bottom of the vertical cultivation, it is still impossible to obtain sufficient light conditions.

Nowadays, land resources are extremely precious, and the land cost occupied by seaweed seedling cultivation is very huge. Experiments have shown that Porphyra variegata adopts the vertical culture method, as long as the light can be guaranteed, its seedling raising effect is equivalent to that of the flat culture method. And Porphyra zebra has never adopted the vertical culture method, because even if the method adopts artificially regularly turning the shells up and down, the synchronous growth, development, and maturity of the shells cannot be reached, resulting in low seedling efficiency.
