Background technology
Often use chemical fertilizer or bright farm manure to accelerate fish growth speed in existing aquaculture such as flower, the silver carp fish farming process, but can cause a large amount of water environment pollutions, seriously hinder freshwater fish and culture development process.Also useful fish guano is cultured, but certain pollution that also has been suitable alleviation, used fish guano mainly is two big class, i.e. monoculture fish technology.Traditional fertilizer has its advantage, but shortcoming is function singleness, and is longer by the process that plant plankton utilized, and consumes a large amount of oxygen in the water body in mineralisation process, this in the water to put growths such as product such as fish in a suitable place to breed unfavorable.The inorganic fertilizer function is also comparatively single, uses a series of problems such as quality of bringing environment, water quality and fishery products in a large number.Except that the fertilizer and inorganic fertilizer of simple function, from last century the eighties also begin to promote " rational application of fertilizers ", i.e. " composite organic-inorganic fertilizer ", though composite fertilizer has absorbed the advantage of single fertilizer and inorganic fertilizer two aspects, their shortcoming is not fine to be overcome.The main problem of prior art is that fish growth slowly causes raiser's economic benefit not obvious, and resistance against diseases is poor, be applied in aquaculture water after, water body is glossy dark green look.And filter-feeding fish such as flower, silver carp, required best aquaculture water is a dark brown, this water colour is mainly formed by xanthophyta, latent algae, diatom, chrysophyceae thalline intrinsic colour.
Summary of the invention
For overcoming the shortcoming of prior art, the invention provides a kind of flower, the special-purpose Chinese herbal medicine alga culturing essence of silver carp, can change aquaculture water algae phase structure fast after using, make other bad water colour change the effect of the dark brown water quality colored, that the silver carp growth is required into, make flower, silver carp growth simultaneously fast, and improve the resistance against diseases of fish, and reduce fish medicine usage quantity, increase the family economic benefit of breeding fish.
The present invention is achieved in that
A kind of flower, the special-purpose Chinese herbal medicine alga culturing essence of silver carp are made up of following raw materials by weight: bird fermentation materials 65-85%, zeolite powder 3-10%, diammonium phosphate 5-10%, vitriolate of tartar 1-3%, sal epsom 0.05-0.08%, gypsum 1-4%, mung bean 2-9%.
Further scheme is: Chinese herbal medicine alga culturing essence includes following medicinal herb components: Radix Angelicae Sinensis 0.1-0.4%, Radix Codonopsis 0.1-0.4%, bark of eucommia 0.1-0.3%, Wu Chia Pee 0.02-0.12%, matrimony vine 0.02-0.12%.
Further scheme is: described bird fermentation materials refers to the material that chicken manure or quail excrement form through normal fermentation.
A kind of flower of the present invention, the special-purpose Chinese herbal medicine alga culturing essence of silver carp have following function and characteristics:
1, cultivates in the water body plant plankton and comprise unicellular algae such as diatom, latent algae, xanthophyta etc. and zooplankton such as wheel animalcule, cladocera, copepods etc., for fish provide competent natural bait; Have remarkable promotion fish growth simultaneously, improve water quality comprehensively.
2, this product contains special natural Chinese medicinal herb composition, greatly improves the fish resistance against diseases.
3, use this product have rapid-action, nutrient is lasting, utilization ratio is high, pollution-free, characteristics such as cost is low.
Embodiment:
A kind of flower, the special-purpose Chinese herbal medicine alga culturing essence of silver carp are made up of following raw materials by weight: bird fermentation materials 65%, zeolite powder 10%, diammonium phosphate 10%, vitriolate of tartar 3%, sal epsom 0.08%, gypsum 3%, mung bean 8.92%, Radix Angelicae Sinensis 0.2%, Radix Codonopsis 0.2%, the bark of eucommia 0.2%, Wu Chia Pee 0.08%, matrimony vine 0.08.
