Embodiment 1

[0037] A kind of in-situ restoration method of sea cucumber pond, its step comprises:

[0038] (1) Pond pretreatment

[0039] Under the condition of pond water temperature of 12-30℃, the pond ecosystem will evolve from an unbalanced state in which pollution is greater than self-purification, which is not suitable for the survival of sea cucumbers, to a balanced state of dynamic regulation of the ecosystem, and the threat and elimination of the bad bottom environment to the survival of sea cucumbers will be improved and eliminated. growth effects;

[0040] (2) Stirring the bottom of the pool

[0041] Use mechanical bottom stirring equipment to stir the bottom of the pond, and the beneficial microorganisms can make full use of the bottom mud to restore the bottom quality environment of the pond in situ;

[0042] (3) Putting in compound beneficial microorganisms

[0043] Add compound beneficial microorganisms to the bottom of the pond;

[0044] (4) Oxygenation

[0045] 1-3 d...

Abstract

The invention discloses an in-situ repairing method of a sea cucumber pond. 1-3 days after composite beneficial microorganisms are added to the pond bottom, bottom stirring and oxygen aeration equipment is utilized, manual pond bottom sediment stirring is conducted, suspension, decomposition and reutilization of bottom mud are achieved, and various harmful substances at the pond bottom are removed. Pond bottom stirring is conducted once every 3-7 days, and the stirring area does not exceed 20% of the total pond bottom area. According to the method, the combined action of the beneficial microorganism and the mechanical bottom stirring equipment is utilized for achieving in-situ repairing of the sea cucumber pond; in high-temperature summer, compared with a pond managed by adopting a traditional method, the survival rate of sea cucumbers in the sea cucumber pond managed by utilizing the method is increased by 15% or above; compared with the pond managed by adopting the traditional method, the weight gain rate of the sea cucumbers in the sea cucumber pond managed by utilizing the method is increased by 20% or above; by adopting the method for repairing the pond, the sea cucumbers canbe bred for a long time in an aging pond or intensive breeding pond used for the sea cucumbers on the premise of not mechanically removing pond bottom sludge, and the high yield and the stable production are achieved.

Description

technical field [0001] The invention relates to the technical field of pond restoration, in particular to an in-situ restoration method for sea cucumber ponds. Background technique [0002] Sea cucumbers are completely benthic, detritus-feeding, omnivorous and herbivorous marine economic animals. They have a small space for feeding and a short range of activities. They cannot move freely and choose the most suitable living space like fish and shrimps and other swimming animals. Eat nutritious bait. Sea cucumber is a well-known "scavenger" among marine animals, and has a strong ability to adapt to poor substrate environments. In general, after 3-5 years of cultivation in sea cucumber ponds, residual bait, feces, remains of dead organisms (algae, fish, shrimp and other small aquatic animals) at the bottom of the pond, and a large amount of water brought to the bottom of the pond by long-term inflow and drainage Organic detritus etc. are mixed together to undergo complex bioc...
