Description
Technical field
The invention belongs to agricultural ecotechnique field, be specifically related to the offspring seed cultivation method of a farming fish.
Background technology
Rice field fish culture is that with breeding fish, kind of rice is combined in same place, promote the benign cycle of paddy ecosystem, make rice field from structurally and functionally reasonably being transformed, give full play to the carrying that paddy ecosystem is maximum, rice fish is made to complement each other, phase moral benefit is evident, and reaching both has common Life Basis and stake.
Abiotic component in paddy ecosystem has oxygen, carbon dioxide, water, inorganic salt and daylight etc., and these are all necessary to the life of various animal and plant.Biotic component composition in paddy ecosystem has Oryza sativa L., fish, weeds, plankton, aquatic insect, microorganism (including photosynthetic bacteria) etc..In these biomes, Oryza sativa L. is the main body in paddy ecosystem, and it absorbs luminous energy, moisture, carbon dioxide and mineral nutrition in large quantities, manufactures Organic substance by means of photosynthesis, then passes through the conversion of energy, operating and storage, forms Oryza glutinosa.Meanwhile, the substantial amounts of weeds in field, plankton and other aquatile, photosynthetic bacteria etc., carry out the conversion of energy, operating and storage too, but they not only can not provide effective product, but also to fight for nutrition with Oryza sativa L., occupy ground space and energy of the sun.
In order to make Oryza sativa L. prevail over competition, it is necessary to elimination weeds, and remove the result of weeds, make soil fertility decline, waste nutrition and energy of the sun that weeds draw.It addition, substantial amounts of plankton, antibacterial and other aquatiles are run off along with paddy field drainage, fly out after the emergence of some aquatic insects the water surface, also causes soil nutriment in a fertilizer and daylight loss of energy directly or indirectly.And after rice field fish culture, it is possible to the material that these will be lost fully utilizes, and can play the effect retained.Meanwhile, ingesting and movable of fish, energy chesson, change the crumb structure of soil, break the sealing of soil surface clay layer, be conducive to breathing and the growth of rice root, thus promoting the effective tillering of Oryza sativa L..On the other hand, the feces of Fish and Excreta again can as the fertilizer of Oryza sativa L., and it is that Oryza sativa L. carries out photosynthetic carbon source that Fish breathe the carbon dioxide discharged.So, play Fish positive role in paddy ecosystem with regard to active, promoted various material to circulate on the spot, to rice, fish both towards favourable direction flowing, the productivity in rice field can be greatly improved.
Field fish, formal name used at school Oujiang Color Common Carp, Cyprinus carpio var. color, in its gonad development and reproductive process to the requirement of environmental condition unlike Mylopharyngodon piceus, Ctenopharyngodon idellus, Hypophthalmichthys molitrix, Aristichthys nobilis strict, can natural propagation in China north and south various places flowing water and hydrostatic.And be suitable for the Ctenopharyngodon idellus of paddy field aquaculture, chain fish, Aristichthys nobilis just can carry out artificial propagation at the fish seeding ground having Special Equipment.Although bolti adapts to paddy field aquaculture, breeding is also easy, but warming requirement height of surviving the winter, benefit is low；Misgurni anguillicaudati energy natural propagation, is currently in examination and supports the stage.Owing to field fish breeds easily, wide adaptability, remarkable in economical benefits, it is particularly suitable for paddy field aquaculture.Utilizing paddy field resource to carry out field fish seed rearing, both can solve the seed source of rice field fish culture, can save again cost of breeding fish increases income.
