Description
Technical field:
The present invention relates to a kind of inorganic fertilizer, relate in particular to a kind of Phoshporic mixed salt aquatic culture retrient liquid ard and production method thereof.
Background technology:
Since the eighties, along with constantly improving with large tracts of land of fertilising fish cultural technique promoted the use of, output of aquatic products every year of China is with 12% speed increase, by the end of the year 2003, surplus the aquatic products total amount in the whole nation has reached 7000 ten thousand tons, this has played immeasurable effect to the development of China's aquatic products cause and national development undoubtedly.But conventional fertilising is breeded fish and has also been buried hidden danger dearly to water resource, ecotope and fisheries sustainable development etc.Particularly in recent years, in China's freshwater fish breeding process, the somebody is in order to pursue temporary transient economic benefit, not stinting to sacrifice ecotope is cost, the inorganic fertilizer of disorderly throwing, lavishment high residue, high pollution and in water body without the people and animals of becoming thoroughly decomposed, poultry manure fertilizer, cause the landlocked most of water body of China to be subjected to pollution in various degree, body eutrophication is on the rise.Existing lake of China and large, medium and small type reservoir fish-carrying ability generally descend, and fish crop reduces year by year and since the eutrophication of water body make China originally the freshwater resources of famine make the matter worse especially.For example: the section of bad V class water quality had accounted for 60.7% in 56 water quality monitoring sections of Haihe basin in 2000; In 16 water quality monitoring sections of Liaohe River Basin, bad V class water quality accounted for 62.4%.Monitor having carried out 51 reservoirs of breeding fish that apply fertilizer, its bad V class water quality has accounted for 47.8%.Trace it to its cause: the one, conventional inorganic fertilizer is breeded fish, and generally adopting with general calcium is the fertilizer application mode of P elements, that is: and general calcium adds that carbon ammonium, general calcium add the sulphur ammonium, general calcium adds urea etc.Dephosphorization ammonium, urea effective component content are higher, solvability big outside, other inorganic fertilizer all belongs to the solid fertilizer of low content, low dissolving, after in case these fertilizer directly drop into water body, its effective ingredient be difficult at short notice be dissolved in the water (particularly in early spring and early winter), and along with self residue deposits to the bottom, mix together with bottom mud, series of chemical takes place, generate water-fast tricalcium phosphate, hydroxyapatite and fluor-apatite.And in course of reaction continuous release of carbon dioxide, carbonic acid gas is dissolved in the water, and impels its pH value to descend, and makes the water quality acidifying.Simultaneously when producing superphosphate, mostly be rich in the mineral matter of black in the used rock phosphate, these mineral matters and sulfuric acid reaction can both generate the water-soluble atrament of speed greatly, in a single day these atraments enter water body, can make the water quality blackening, thereby hinder the direct projection and the scattering power of light, the photosynthesis ability is weakened greatly.On the low side at pH value, in the water body of photosynthesis difference, plankton particularly growth and the breeding of phytoplankton can be subjected to serious restriction, in case the growth and breeding of phytoplankton is restricted, just can not fully absorb the free carbon dioxide in the water body, emit fresh dissolved oxygen, cause the dissolved oxygen in the whole water body on the low side and low excessively, thereby influence the fish-carrying ability of water body and fish crop then.The 2nd, random throwing, throw people and animals, poultry fertilizer excessively.After these organic manure drop into water body, sink to the bottom in the lump, can only be decomposed into hydrogen sulphide (H on the one hand by the anaerobic digestion of anaerobic bacteria with the ight soil of fish drainage, the corpse after the animal and plant death
2S), nonionic ammonium (NH
3), methane (CH
4) etc. harmful substance, these materials are to fish and toxic effect of biological feed and harmful effect.Resolve into organic acid on the other hand, organic acid can impel water PH value to descend, the water quality acidifying, thus suppress planktonic growth and breeding, cause the scarce bait of fish and stop or slowing down growth.Simultaneously, the subacidity water body is the suitable environment of multiple germ growth and breeding, and fish are infected in the breeding of pathogeny bacterium raised growth, impels the fish large tracts of land that popular, fulminant disease take place.The 3rd, after a large amount of organic manure drops into water body, residue more than 90%, excreta, dead is moving, necron, considerably beyond the self-purification capacity of water body, cause these materials to be accumulated in reduction zone in a large number, in time decomposition and inversion becomes benefit materials, material circulation and energy that these materials can destroy in the water body flow, the lighter hinders the normal growth of fish, and output descends, and heavy water body water quality is ruined, lose value, not only can't proceed fish production, and can't be used for field irrigation, make whole water body uncultivated comprehensively, even bring disaster to the downstream water system, destroy the ecological balance of whole water system.
