Description

Fresh water scale pond ecological cultivation system
Technical field
The invention belongs to technical field of aquaculture; relate to a kind of fresh water scale pond ecological cultivation system, it is characterized in that by cultivating pool, pond water original position dispersion treatment, pond discharge water dystopy focus on, backwater function recovery process and pond water quality compensation deals five parts form.
Background technology
At present, China is in and economizes on resources, protects under the situation of environment, advocates closed circulation pond culture mode energetically.And traditional pond breeding ecological environment is compared with the complicated ecosystem in natural rivers, lake, the comparison fragility seems, the self-purification capacity that lacks continuation, can not satisfy demands of social development, transform existing breeding way as the closed circulation cultivation mode, still have many technical barriers to need to be resolved hurrily.
Traditional breeding way, the ingesting of fishes and shrimps, metabolism and survival activity are all in same pond waters.The metabolism of constantly fertilising, bait throwing in and fishes and shrimps makes limited water body lose its reduction and restore funcitons gradually.The wawter bloom phenomenon usually appears in the pond, and wawter bloom has covered the water surface, has intercepted illumination and exchange gas, has suppressed the photosynthesis of phytoplankton, causes dissolved oxygen in water to reduce, and influences the culturing fish and shrimp growth.If do not take measures, wawter bloom will rot to decompose, and consumes oxygen, worsens water quality.Then, harmful substances such as hydrogen sulphide, ammonia nitrogen increase severely, and the animals and plants of breed make whole pond ecosystem collapse also because of poisoning and anoxic death.Therefore, the key issue of pond ecosystem is: how to solve and keep the dynamic material balance problem of pond input and output, how to solve the regulation and control problem of pond scale pond culture and water quality?
In documents and materials, at present, experts and scholars have carried out many research work both at home and abroad, mainly can reduce physics, chemistry and biological three aspects, and similar techniques has both at home and abroad:
Research aspect physics has: a kind of pond water quality clearing machine of Zhou Yan (2006) (CN2903037Y); Wang Yanmin (2009) pond culture hydathode (ZL200920017226.7); U Wagner (2008) is used for the surface suction device (CN101260746A) of pond or similar site; A kind of method (CN101367565A) of removing blue-green algae in the pond of Wang Yemiao (2008).
Research aspect chemical has: a kind of preparation of killing moss in the cultivating pool of Huang Zhongping (2009) and preparation method thereof (CN101703052A).
Research aspect biological has: Smith D W. (1985) puts filter-feeding fish shellfish in a suitable place to breed plankton in the water body and water quality condition is also had considerable influence, fish reduce the biomass that ingesting in a large number of phytoplankton can not make phytoplankton, and this is because more small-sized algae is bred; The experiment of Richardson (1990) shows that carp is unfavorable for the growth of pasture and water, and the abundance of benthonic invertebrates is reduced significantly, but can improve algae bio amount and primary productivity; Carpenter S R (1987) fish ingest to zooplankton then can alleviate the pressure of ingesting that phytoplankton is born, phytoplankton biomass and primary productivity thereby rising, and the fish force of labor also can be improved.Wang Yufeng (1990) is cultivated fresh water fingerling experiment (aquatic product journal) with photosynthetic bacteria liquid; The Chen head of a family (2008) is a kind of to utilize elastic filler to make up the method (CN101333034A) that microbial film purifies water in the pond.Meng Rui (2010) immobilized bacterium-frond is the research (Master's thesis) of purifying aquaculture waste water; A kind of box-type biological floating bed and using method (CN101828538A) of Gu Zhaojun (2010).
Have in the research aspect comprehensive such as physics, chemistry and biology and engineering etc.: Li Deshang (1998) has adopted a plurality of ponds ecosystem inflow and outflow of water, has united the biological modulated control techniques of water quality adjustment; Shi Fusheng (2000) cycle water carries out the method (CN1297678A) of pond aquaculture; A kind of pool culturing composite system (CN101023741A) that has water saving and security function concurrently of Li Gu (2007); A kind of ecological engineered pond culture system (CN201709241U) of Yu Deguang (2010); A kind of water quality of pool complex culture regulate and control method of Liu Xingguo (2009) and regulator control system (CN101642076A).
From analysis, physical method reduces desilting, precipitation, filters and changes water, and reaching the purpose of the ecotope that improves water body, shortcoming is to be cost to sacrifice external environment condition.Chemical method reduces throws in chemicals and oxidation medicament, and shortcoming is in sterilization and oxygenation, has also destroyed the ecological balance, causes secondary pollution; Pharmacology is not clear, and consumption is unclear, also can cause the residual of medicine or poisoning.Biological method reduces and adds probiotics, and as microorganism and algae preparation, shortcoming is that water body is more little, the easy more fluctuation that causes pond physics and chemistry and biological indicator.Three kinds of methods are used, and all produce certain operating cost, all external environment condition are exerted an influence, and therefore, it is imperative that sealing is cultured.
Integrated approach, being primarily aimed at is in blocks or scale pond, the deficiency of existence has: the one,, the input and output in breeding way pond, traditional pond exists seriously unbalance.Along with culturing vegeto-animal growth, the material of input constantly accumulates, and lacks the effective ways that pond accumulation thing constantly removes; The 2nd,, for pond ecosystem in blocks, be difficult to satisfy the demand of regulation and control only according to one or two technology, lack the system's combing and the integration of prior art and technological process, equipment coupling and integrated; The 3rd,, the pond structure and between relation, exist unreasonablely with the compensation of supplying water, culture though sealing occurred, mostly be the pond series system, in case shortcoming is that disease takes place, involve whole series connection pond, be difficult to prevention and control.At present, how to solve fresh water scale pond ecosystem and have above-mentioned problem, the bibliographical information that Shang Weiyou is relevant.
