Abstract
The invention discloses a blue algae prevention method in a freshwater shrimp pond. The method comprises the steps: emptying a pond, and drying the pond in the sun; filtering and injecting water for the first time; splashing trichloroisocyanuric acid; planting float grass; filtering and injecting water for the second time; applying biological liquid fertilizer; and stocking shrimp postlarvae and the like. According to the method, growth of algae cells is inhibited until the blue algae are killed by utilizing high-concentration trichloroisocyanuric acid in early phase of preparing the pond due to the fact that the freshwater shrimp has short growth period; and beneficial algae is cultured by water injection and fertilizer application to inhibit blue algae growth, so that a series of problems caused by the blue algae are fundamentally stopped, healthy biological freshwater shrimp culture is realized, and the culture cost is reduced.
Description
Technical field
The present invention relates to the method for a kind of freshwater shrimp pond prevention blue-green algae.
Background technology
Freshwater shrimp (Macrobrachium nipponense), the formal name used at school Japanese macrobrachium supernbum is the important economic freshwater shrimps of China.Advantages such as that freshwater shrimp has is nutritious, fine and tender taste, delicious flavour.Because people are to the increase of freshwater shrimp demand, and the shrimp culture cost is low, income is fast, and advantages such as profit height have expedited the emergence of the development of shrimp culture industry.And the problem that faces in the shrimp culture process is also more and more, and blue algae bloom then is a wherein serious relatively problem in the pond.
Blue-green algae is a kind of algae wide, that adaptability is very strong that distributes, continuous expansion along with the shrimp culture scale, improving constantly of intensification degree, blue-green algae also day by day manifests the influence of freshwater shrimp, and the back accident that production damages to shrimp culture takes place and happens occasionally in blue-green alga bloom.
The harm of blue-green algae mainly contains:
One, a large amount of breedings form " wawter bloom ", form the material of the thick similar paint sample of one deck on the pond waters surface, reduce the dissolved oxygen amount in the pond water, even more serious is, some kind (as Microcystis aeruginosa) in the blue-green algae also can produce toxin (being called for short MC), can directly cause toxic action to freshwater shrimp;
Two, suppress other algae grows, blue-green algae itself has superpower fixed nitrogen function, so ability in contention water aspect the nutrition, blue-green algae all is eager to excel than other any algae, be easy in water, form dominant population, itself can not be absorbed by animals such as freshwater shrimps again, therefore can influence the growth of freshwater shrimp;
Three, after death a large amount of oxygen consumptions can produce a kind of unpleasant stench flavor after the blue-green algae death, consume a large amount of oxygen, can produce toxin after decomposing simultaneously, ruin water quality, cause the freshwater shrimp mortality.Therefore, the present invention will take measures from the source, stop the growth and breeding of blue-green algae in the shrimp culture pond, and the growing environment of a health is provided to freshwater shrimp.
Summary of the invention
Purpose of the present invention is exactly the problem that fundamentally solves the blue algae bloom in the shrimp culture process, provides a kind of breeding environment of the health that is fit to grow to freshwater shrimp, thereby improves the quality of freshwater shrimp.
Realize the object of the invention main technical schemes: filtered water inlet in the pond at the bottom of drying the pond, the strong chlorine oil of splashing then, the plantation pasture and water, and cooperate biological rich water, create a growing environment that does not have blue-green algae to freshwater shrimp.
Step of the present invention is as follows:
(1) do the pool, shine the pool: shine the pool require to shine turn white at the bottom of the pool comprehensively, stiff cracking, dried more good more.
(2) filter water filling: select cleaning, meet the cultivating condition water source of (promptly meeting GB 11607 and NY5071), and to use mesh be that the above screen pack of 60 orders filters, be filled to 50cm.
(3) strong chlorine oil of splashing: according to one kilogram every mu usage amount full pool spilling head strong chlorine oil.
(4) plantation pasture and water: behind the strong chlorine oil of splashing 2 days, can plant pasture and water (optional hydrilla verticillata), according to spacing in the rows 1m, line-spacing 4m, 8～10 plantations of every strain hydrilla verticillata.
(5) filter water filling: plantation pasture and water 5 days, after pasture and water take root, can filter and be filled to 80cm.
(6) biological rich water: carry out biological rich water, promptly the fertilizer crossed of biofermentation cooperates photosynthetic bacteria to use together, promotes the growth of useful algae and pasture and water
(7) throw in the shrimp seedling: rich water is after three days, and water colour is stable, can throw in the shrimp seedling, every mu 8～100,000
Advantage of the present invention and effect: the present invention is short vegetative period according to freshwater shrimp, preparing the pond in earlier stage, just utilizes the strong chlorine oil of high concentration, to the growth generation inhibitory action of frustule, until killing blue-green algae.Useful algae is cultivated in the water filling fertilising again, suppresses blue algae growth, fundamentally stops a series of problems that blue-green algae brings, and realizes healthy ecology breed freshwater shrimp, reduces aquaculture cost.
Embodiment
Further the present invention is elaborated below by instantiation.
Example 1:
3 mu of pond areas, after shining the pool, filter and be filled to 50cm, the 3 kilograms of strong chlorine oils of splashing, after 2 days, by spacing in the rows 1m, line-spacing 4m kind is planted hydrilla verticillata, after the pasture and water survival in 5 days, continue to be filled to 80cm, carry out bio-fertilizer water after three days, 80,000 shrimp seedlings are thrown in for every mu in the stable back of water colour, and whole breeding process does not have blue-green algae and occurs.
Example 2:
5 mu of pond areas, after shining the pool, filter and be filled to 50cm, the 5 kilograms of strong chlorine oils of splashing, after 2 days, by spacing in the rows 1m, line-spacing 4m kind is planted hydrilla verticillata, after the pasture and water survival in 6 days, continue to be filled to 80cm, carry out bio-fertilizer water after three days, 90,000 shrimp seedlings are thrown in for every mu in the stable back of water colour, and whole breeding process does not have blue-green algae and occurs.
Example 3:
8 mu of pond areas, after shining the pool, filter and be filled to 50cm, the 8 kilograms of strong chlorine oils of splashing, after 2 days, by spacing in the rows 1m, line-spacing 4m kind is planted hydrilla verticillata, after the pasture and water survival in 5 days, continue to be filled to 80cm, carry out bio-fertilizer water after 4 days, 100,000 shrimp seedlings are thrown in for every mu in the stable back of water colour, and whole breeding process does not have blue-green algae and occurs.
