Description
Technical field
The present invention relates to Procambius clarkii raising technology field more particularly to it is a kind of utilize winter-fallowed paddy field carry out kirschner original chela
The method that shrimp breeds in situ.
Background technique
Procambius clarkii (Procam barus clarkii) also known as freshwater lobster, lead and cadnium, local name earth ridge shrimp,
Cray is subordinate to Arthropoda, Crustachia, Decapoda, Chong La mqb section, Astacinae, former Astacus.In recent years due to market
In great demand, Procambius clarkii cultivation scale constantly expands, and with the comprehensive breeding Technique Popularizing application of rice shrimp, Procambius clarkii is produced
Industry development prospect is more wide.Such as published Anhui Native standard winter-fallowed paddy field cultivation Procambius clarkii technical operation rule
Journey etc., the cultural technique of Procambius clarkii is relatively mature at present.
However Procambius clarkii seed breeding technology relatively falls behind, breeding scale seriously lags, and causes seed short, limits
The development of Procambius clarkii industry.Therefore it solves the problems, such as seed scarcity, it is particularly important to form stable Seedling production ability.
Summary of the invention
The present invention provides the problems in for background technique and a kind of carries out Procambius clarkii breeding in situ using winter-fallowed paddy field
Method, its object is to: carry out Procambius clarkii original position breeding mode using in winter-fallowed paddy field, which can make full use of the winter
Not busy rice field is bred in situ by Procambius clarkii, solves Procambius clarkii seed shortage problem, rice shrimp aquaculture is promoted to stablize hair
Exhibition.
To achieve the goals above, the technology of the present invention solution is as follows:
A method of Procambius clarkii, which is carried out, using winter-fallowed paddy field breeds in situ, specifically includes the following steps:
(1) parent selects and launches: September is just at the beginning of -10 months, selects that limbs are complete, disease-free and injury-free, mobility before rice harvesting
By force, specification makees parent in the mature Procambius clarkii of 25-45g/ tail, different geographical；Launching close shrimp female-male proportion is 2-3:1, is thrown
It is high-volume 20-25kg/667m2。
(2) parent's reinforced cultivating: after parent launches, reinforce prenatal nutrition reinforced cultivating, animal fodder and vegetalitas are raised
Material is fed according to 7:3 proportion；Daily ration of feeding accounts for the 3%-5% of shrimp weight, when water temperature is lower than 15 DEG C, stops feeding.
(3) parent's mating and oogenesis: before late October rice harvesting, 60%-90% parent completes mating, 20%-30% parent
This completion oogenesis；Mid-November, 85% or more parent completed mating, 50% or more parent oogenesis when rice harvesting finishes.
(4) stalk toothing and rehydration overflow field water level management: when rice harvesting, staying height 50-70cm's
High stalk stubble is uniformly dissipated in field, the straw of crushing in rice field；After rice harvesting finishes dry field 3-4d, rehydration overflows field 15cm
The depth of water, 4-5d add water 15-20cm later, precipitation 20-30cm after 6-7d, plant waterweed in field face；After water plant has been planted, add
Water is kept rice stubble to expose the surface, can both be regenerated with rice stubble, and provide sufficient food, and can be to avoid rice to field face 35-45cm is higher than
Stubble floods causes water body to degenerate under water.
(5) cultivation of juvenile prawn is just incubated: at the beginning of 11 months-by the end of November, there is the shrimp with ovums hatching farrowing of 15%-25%,
It feeds soya-bean milk 2 times, splashes along ridge surrounding daily.
(6) Winter-Spring water table management: at the beginning of 12 months-by the end of February, keep Soil surface water deep in 50-60cm；March early declines
Low water level is conducive to improve water temperature in rice field, water level is improved at the beginning of 4 months to 60-70cm, promotes Procambius clarkii raw to 30-40cm
It is long.
(7) spring water quality management: dissolved oxygen amount is not less than 4mg/L, pH 7.0-8.4；At the beginning of 3 months-by the end of April, it changes and adds every 20d
Water l times, each 1/4-l/3, monthly alternately splash l 15g/m3Quick lime and 5g/m3Photosynthetic bacteria, to improve water quality.
(8) spring juvenile shrimp cultivation: at the beginning of 3 months, juvenile prawn starts feed of appearing, but water body is thiner, and impose decomposed has per acre
Machine fertilizer 80-100kg, full pool spilling head, quick rich water are cultivated the natural baits such as planktonic organism and are utilized for young shrimp；Animal fodder with
Plant feed is fed according to 7:3 proportion, and along pond, surrounding is fed 2 times daily, and day feeding volume accounts for the 4%-5% of shrimp total weight.
(9) timely fishing: mid-April, catches big specification Procambius clarkii seedling in due course, the shrimp seedling for stopping 3-6g/ tail is used for
At shrimp aquaculture.
Preferably, the step (2) and step (8) animal bait select small fish, spiral shell meat, river
Freshwater mussel meat, earthworm, pluck or silkworm chrysalis.
Preferably, the step (2) and step (8) vegetal bait selection corn, vinasse, wheat, pearling cone meal, rice bran,
Wheat bran or bean dregs.
Preferably, step (2) Feeding time are as follows: morning 8-9 point is fed once, accounts for the 20%-30% of daily ration of feeding；Under
Noon 5-6 point is fed 1 time, accounts for the 70%-80% of daily ration of feeding.
Preferably, waterweed the spacing in the rows 2m, line-spacing 6m of step (4) plantation.
Preferably, step (5) Feeding time are as follows: morning 8-9 point is fed once, accounts for daily ration of feeding
20%-30%；Afternoon, 5-6 point was fed 1 time, accounted for the 70%-80% of daily ration of feeding.
Preferably, step (8) Feeding time are as follows: morning 8-9 point is fed once, accounts for the 20%-30% of daily ration of feeding；Under
Noon 5-6 point is fed 1 time, accounts for the 60%-70% of daily ration of feeding.
Compared with the prior art, the beneficial effects of the invention are that:
The present invention utilizes winter-fallowed paddy field, carries out Procambius clarkii in winter-fallowed paddy field and breeds in situ, passes through (2) parent's reinforced cultivating；
(3) parent's mating and oogenesis；(4) stalk toothing and rehydration overflow field water level management；(6) Winter-Spring water table management；(8) spring juvenile prawn is trained
It the key technologies such as educates, effectively improves the ability that Procambius clarkii breeds in situ, improve seed yield.

Embodiment:
(1) parent selects and launches: September 17th, selecting that limbs are complete, disease-free nothing before rice harvesting
Wound, mobility be strong, specification in the mature Procambius clarkii of 25-45g/ tail, different geographical makees parent.Launch close shrimp male and female
Ratio is 3:1, injected volume 225kg/667m2, rice field area 1300m2。
(2) parent's reinforced cultivating: after parent launches, reinforce prenatal nutrition reinforced cultivating, animal fodder and vegetalitas are raised
Material is fed according to 7:3 proportion, and daily ration of feeding accounts for the 3%-5% of shrimp weight.Morning 8-9 point is fed once, accounts for daily ration of feeding
20%-30%；Afternoon, 5-6 point was fed 1 time, accounted for the 70%-80% of daily ration of feeding.By reinforced cultivating, enhances close shrimp constitution, improve parent
Shrimp hatching quality.
(3) parent's mating and oogenesis: before October 20 rice harvesting, 75% parent completes mating, and 20% parent completes to embrace
Ovum；When November 12, rice harvesting finished, 85% or more parent completes mating, 50% or more parent oogenesis.
(4) stalk toothing and rehydration overflow field water level management: when rice harvesting, staying height in the high straw of 60cm
Stalk stubble is uniformly dissipated in field, the straw of crushing in rice field.After rice harvesting finishes dry field 4d, rehydration overflows the field 15cm depth of water,
15-20cm is added water after 5d, precipitation 20-30cm after 7d plants waterweed, spacing in the rows 2m, line-spacing 6m in field face.Water plant has been planted
