Abstract

The invention discloses a crucian fry manure cultivation method, comprising the following steps: (1) carrying out roe incubation, specifically, injecting an odinagogue into crucians in a manual simulation natural environment, then putting the female and male crucians into a pond according to the proportion of 1: 1 to enable the crucians to naturally spawn and be fertilized and incubate, wherein glucose is selected as the artificial odinagogue for breeding fish fries; (2) fermenting a fertilizer of a fry-rearing pond in advance, wherein livestock and poultry manure and human excrete are taken as the fertilizer, diluting the manure by adding water, and then evenly splashing the diluted manure into the whole pond; (3) digging a big pit beside the pond, wherein the size of the pit depends on the specific circumstance; after that, pouring fresh excrement into the pit, and then adding a right amount of lime into the pit; (4) carrying out fertilization for once every day after the fish fries are put into the pond, wherein 50-100kg of manure is applied to per mu of the pond.

Description

A kind of young crucian muck cultivating method

Technical field

The invention belongs to technical field of aquaculture, be specifically related to young crucian muck cultivating method.

Background technology

In recent years, China's culture fishery obtains quickly development, the particularly yield of tradition freshwater aquiculture and is constantly carrying Height, but the cultural technique of fry is crucial, typically cultivate entering pond from fry 2 age this section of production process of fingerling be referred to as Fry and fingerling rearing, traditional fresh water young fish breeding way is that kind of a fish is rendered to water body in addition simple feeding and management, or Fry resource in water body is carried out natural propagation and protection, thus obtains the mode of production of high yield fry.

Summary of the invention

It is contemplated that overcome the defect of prior art, it is provided that a kind of young crucian muck cultivating method, method is relatively simple, energy Adapt to the needs put in a suitable place to breed spring, shorten the fry culture-cycle, improve yield, be also adult fish rearing Operational preparation abundant amount quality Superior material base.

In order to solve above-mentioned technical problem, the invention provides following technical scheme:

A kind of young crucian muck cultivating method, comprises the steps, 1) hatching of fish roe, in manual simulation natural environment, will After Carassius auratus injection odinagogue, female, milter is put in the ratio of 1: 1 allow in pond its natural spawning, be fertilized, hatch；Select glucose Fry is bred as artificial induced spawning agent；2) utilizing poultry, brid guano urine and night soil to be used as the fertilizer in fry rearing pond, fertilizer is by pre- First ferment, is uniformly splashed in backward for muck dilute full pond；3) hollow place is dug on limit, pond, depending on its size concrete condition, The most fresh excrement is poured in hole, adds appropriate Calx；4) under fry, behind pond, every day applies fertilizer 1 time, every mu 50～100 public affairs Jin.

Further, the 3rd step, fertilizer first passes through abundant fermentation maturity in advance.

Further, the 3rd step, the first 7 days first basal dressings in pond under fry, every 667m2 executes animal manure or human urine 300 kilograms, Breeding natural bait is biological, ingests for fry.

Further, the 4th step, apply fertilizer every day 1 time, the most every 667m2 fertilising double centner, after the slurrying that adds water, full pond is uniform Splash.

Compared with prior art, the present invention has a following beneficial effect:

Fry cultural method of the present invention is relatively simple, adapts to the needs that Carassius auratus is put in a suitable place to breed spring, shortens the fry culture-cycle, improve and produce Amount, the material base also having good quality for adult fish rearing Operational preparation abundant amount.Fry premunition is strong, and survival rate is high, water quality Fertilizer degree is more stable, and summer flower body constitution is strong.

Detailed description of the invention

Hereinafter the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is only used In the description and interpretation present invention, it is not intended to limit the present invention.

1 one kinds of young crucian muck cultivating methods of embodiment, comprise the steps, 1) hatching of fish roe, manual simulation from So in environment, after Carassius auratus is injected odinagogue, female, milter is put in the ratio of 1: 1 allow in pond its natural spawning, be fertilized, incubate Change；Glucose is selected to breed fry as artificial induced spawning agent；2) poultry, brid guano urine and night soil is utilized to be used as the fertilizer in fry rearing pond Material, by fermenting in advance, is uniformly splashed in backward for muck dilute full pond by fertilizer；3rd step, fertilizer first passes through in advance fully to be sent out Ferment becomes thoroughly decomposed, it is to avoid fresh excrement directly applies pond.3) hollow place is dug on limit, pond, depending on its size concrete condition, the most fresh Excrement is poured in hole, adds appropriate Calx, and muck so can be made fully to ferment.Also can kill presumable part in excrement sick Bacterium, parasite and parasitic ovum etc., prevent or reduce pathophoresis.3rd step, the first 7 days first basal dressings in pond under fry, often 667m2 executes animal manure or human urine 300 kilograms, and breeding natural bait is biological, ingests for fry.

4) under fry, behind pond, every day applies fertilizer 1 time, 50～100 kilograms every mu.After fry enters pond, according to water quality fertilizer degree, Weather, water temperature and fry growth situation determine topdressing amount, must regard dose and interval time water colour, fry floating head situation and sky Gas etc. are grasped flexibly.4th step, applies fertilizer 1 every day, and the most every 667m2 fertilising double centner, after the slurrying that adds water, full pond is uniformly sprinkled Spill.

After fry enters pond 4 days, as fry in early morning raises the nose above water to breathe, recover normal after sunrise, illustrate that water fertilizer degree is moderate；If at fine day Still raise the nose above water to breathe after during the morning 8, then explanation water quality overfertilization, should stop or reducing topdressing amount；If not raising the nose above water to breathe, and light should the increasing of water colour chases after Fertile amount.

The foregoing is only explanation embodiments of the present invention, be not limited to the present invention, for the technology of this area For personnel, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in Within protection scope of the present invention.
