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 ...

Problems solved by technology

[0006] The invention provides a method for transplanting and cultivating Gracilaria brittle in northern ponds, which can solve the problems of water quality eutrophication caused by simple animal breeding in northern ponds existing in the prior art, especially in summer high temperature periods, which can keep algae In the rapid growth period, it fills the gap in the summer pond culture in the northern sea area without macroalgae
