Method for implanting and cultivating Gracilaria bursa-pastoris in north pond

Abstract

The invention provides a method for implanting and cultivating Gracilaria bursa-pastoris in a north pond. By using the method, the problems of water eutrophication and the like, caused by the ecological imbalance owning to using the prior art for signal animal breeding in the north pond, can be solved. The cultivation process of the invention can be divided to a sprout proliferation phase, a bottom sowing propagation phase, an increasing interharvesting phase and an overwintering seedling protection phase. By using the invention, the problem that owning to the change of factors such as climate, growing environment and the like in the north, the transplanting of south macrophyte fails, can be solved; the method has effects of low input and high output, and the ratio of the fresh weight input to fresh weight output of the algae is 1:1500. The yield per mu is 1500kg. The method of the invention can be used to fill the gap of cultivating macrophyte in aestival pond of northern areas and the diversity of algae resources in northern China is enriched.

Description

technical field

[0001] The invention relates to a method for transplanting southern seaweeds to northern ponds and artificially cultivating them, in particular to a method for transplanting Gracilaria brittle and artificially cultivating them in ponds. Background technique

[0002] Gracilaria bursa-pastoris is a large economical red algae. The algae branches are cylindrical, branched 2-3 times, alternate, partial or dichotomous, the body color is reddish brown, the algae body is 20-40cm long, and the camp lives. It is mainly distributed in the coastal areas of Zhejiang Province and Fujian Province, and is endemic to my country. Gracilaria brittle, as a large seaweed, plays an important ecological role in optimizing the ecosystem structure of coastal waters, participating in the global carbon cycle, and preventing eutrophication and red tide in sea areas.

[0003] With the rapid development of modern industry, the harmful substances discharged in the production process are ...

Examples

Embodiment Construction

[0030] Selection of algae species: Gracilaria brittle algae in the vigorous growth period were harvested in the coastal area of ​​Fujian in late May. Gracilaria brittle was selected as the algae with strong algae body, luxuriant and neat branches, reddish-brown body color, complete algae body, and no damage and rot. algae species.

[0031] Low-temperature transportation: put the harvested fresh crispy Gracilaria into an incubator, put it in a seawater ice bottle to keep the temperature low, and properly pour it into seawater to keep it moist. The temperature is controlled at 8-12°C, then sealed with a cover, and transported to the northern seawater pond .

[0032] Segmentation of algae: Divide the whole plant of Gracilaria brittle from its base into several parts with a scalpel. The cut algae should maintain the integrity of the plant. The length of the algae should be greater than 15cm, and the wet weight of a single algae should not be less than 8g. There should be no less ...
