Description
Technical field
The present invention relates to animals and plants ecology three dimensional-planting-breeding technical field, more particularly to a kind of lotus rhizome-sweet potato-frog ecology is three-dimensional
Breeding method.
Background technology
Frog fine and tender taste is delicious, full of nutrition, delicious flavour, and has clearing heat and detoxicating, nourishing and fit keeping function and other effects, edible value
And medical value is non-general, is one of rare aquatic products of southern hilly area.It is carried recently as people’s lives level
Height increasingly increases the demand of the frog, and the frog in nature is fewer and fewer, and usually supply falls short of demand in the market, needs to propagate artificially
To supplement market needs.But from the point of view of the most of frog cultural techniques of existing market, in order to improve frog yield, the raiser of many frogs
Often individually raised using nature pool or artificial pond progress high density of building.However, this intensive culture method is not only native
Ground resource utilization is low and aquaculture cost is high, in addition in the frog under highdensity situation, is on the one hand easy to cause disease biography
It broadcasts, is not easy prevention and control, the death rate is high, polluted-water environment in the excreta centralized discharge to water of the another aspect frog, and the frog is close
Spend big, space is small, the frog quality mouthfeel that cultivates out and it is wild be as far apart as heaven and earth, the price of sale also not person of modern times
Meaning.
Invention content
It is an object of the invention to：In view of the above problems, pass through breeding combination, mutualism and ecological prevention and control
Mode, the aquaculture cost that solves foster frog generally existing at present is high, raising poor taste and selling price is low and sweet potato, lotus rhizome kind
The problems such as pesticide and not high benefit are leaned in zoophyte evil prevention and control.
In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is as follows：
A kind of lotus rhizome-sweet potato-frog ecology three dimensional-planting-breeding method, breeding step are as follows：
(1) lotus rhizome is planted：Plot selects and divides lotus field and sweet potato, March start to arrange lotus field, picks up lotus rhizome kind
Lotus rhizome plant is carried out after vernalization, apply fertilizers scientifically irrigation, and spray insect prevention, at the same time cultivates sweet potato seedling；
(2) frog seedling is cultivated：Hatchery is set beside plot, and the April carries out the selection of frog kind, purchase frog's egg is hatched
After forming tadpole, tadpole is put in a suitable place to breed to hatchery and purse seine is set around hatchery, have micro flow keeping hatchery
In the case of carry out bait throwing in and feed to frog complete metamorphosis and terminate；
(3) sweet potato is planted：Four months bottoms, which by sweet potato deep plough to turn over after plough shines to early May, uses sufficient base manure, will be trained in step (1)
The in due course Cultivate administration of sweet potato seedling educated pours in due course and prevents disease pest, and after the completion of sweet potato seedling plantation plot surrounding timber and
Fishing net cloth carries out cofferdam；
(4) frog seedling is put in a suitable place to breed：It treats that purse seine will be opened within ten days or so after metamorphosis by the entrance of frog seedling after the completion of sweet potato seedling plantation
Sweet potato field, feed intake nursing and controlling disease at regular time and quantity on feed table；
(5) sweet potato harvests：50~60 days after the completion of to step (3) the sweet potato seedling plantation, tender leaf portion can be harvested, and adopting
Supplement applies 10kg/ mus of urea after receipts, until removing the tendril of sweet potato, silt after 110~130 days, packs and stores by grade；
(6) frog collecting：It is primary using the screening separation of net matter pocket every two weeks according to frog body size after September, it will
The larger frog screened is placed in spare plot and continues to raise collecting；
(7) lotus rhizome harvests：Mud is washed away after October using giant to be harvested, the part not harvested can be in Tanaka
The water layer of 5cm thickness is stayed to keep the temperature to preserve.
Specifically, the plot selected as quality is loose, soil layer is deep, it is loose ventilation, rich in organic matter and easily row easily fill
Hillside fields, and have low-lying place that can be transformed into lotus field or naturally low-lying make lotus field, the Parcel division with the thicker humidity of mud
Be according to 150~200 square metres for Division sweet potato and lotus field, the sweet potato and lotus field area ratio be 4:1.
Specifically, the arrangement lotus field starts for 2~3 days before plant, to described after with sand suction pump, lotus field mud is extracted out
Lotus field bottom, which arrange, makes one end be slightly above the other end, and the modeling of 2 layers of 0.02~0.05mm thickness is paved in the lotus field bottom
Expect film, then backfill the mud of 15~30cm thickness in the lotus field and use quick lime 50kg or 75% pentachloronitrobenzene per acre
It is even that Tanaka's rake is sprinkled into after the stirring of 2kg and 15kg fine earths, then lotus field is flattened.
Specifically, the selecting lotus root kind is strong for selection adaptation, precocious, shallow life, high yield kind, the kind of the lotus rhizome kind
Class, which includes deep water kind, shallow water kind, sub- lotus root, full branch lotus root, early-maturing variety and late variety, the vernalization, need to select disease-free stalwartness
And branch lotus root at least has the intact lotus root kind of 1 terminal bud, 2 internodes and 3 sections, no disease and pests harm and significant mechanical damage, lotus root bud, it will
