Abstract
The invention discloses a kind of cultural method of rice field ecology cray, it is related to crayfish breeding technique field.The cultural method includes step：Rice field reconstruction, rice field sterilization and fertilising, bait is raised together with, shrimp seedling is delivered, shrimp seedling is fed, field management and fished for into shrimp, in being reconstructed in rice field, ridge carries out increasing processing, smooth baffle plate is set, cray is avoided to escape, reserve a part of space in rice field to be used for planting the pasture and water that cray is liked eating, while raising together with hatching and mud fish fry that some crays are liked eating.The present invention by by cray Collocation cultivation rice field can synchronization gain aquaculture income, increase the income of peasant household, on the one hand increase can prey on grasshopper insect and aquatic harmful organism to the cray grown in rice field, on the other hand, the fallen flowers of spike of rice can as cray food intake, improve the meat taste of cray.
Description
Technical field
The present invention relates to crayfish breeding technique field, and in particular to a kind of cultural method of rice field ecology cray.
Background technology
Cray, belongs to Arthropoda, phase late 1930s is by Japanese incoming China.Cray has the cave that burrows
The life habit in residence and destroy dam, and threaten fry existence, certain destruction is caused to agricultural production and fish production
Act on, therefore early stage people are eliminated as harmful organisms always.In recent years, cray is chased after because of delicious meat
Hold in both hands, good market prospect, but because cray is propagated artificially less, people largely capture wild cray, make its Natural Population number
Amount is less and less, and supply falls short of demand in market, and price drastically rises.In recent years, propagate cray artificially more and more, all build mostly
Special culturing pool is made to be cultivated, and in rural area, the paddyfield water of large area is not utilized effectively, it appears it is more unrestrained
Take.
The content of the invention
The invention provides a kind of cultural method of rice field ecology cray.
The technical solution adopted in the present invention is：
A kind of cultural method of rice field ecology cray, comprises the following steps：
1) rice field is reconstructed, and rice field ridge is transformed, and ridge carries out increasing processing, sets smooth baffle plate, and ridge is high
Degree reaches 0.8~1.0m, and width reaches 60~80cm, and ridge base portion is widened to 1.2~1.5m, and ridge compacting, slope ratio is 1:2~
1:3, interior away from ridge 1m or so of field surrounding is along excavating that 3~5m is wide, deep 1m or so annular to be supported and dig " ten " in the middle of shrimp ditch, field
The field ditch of font and " well " font, furrow width 0.5~1.0m, deep 0.5m or so, the area of the foster shrimp ditch of annular and field ditch accounts for rice
10% or so of field area, inlet channel is individually intake, the independent draining in gutter, makes cray raw in metastable water body
Long, entering the place of discharge outlet should select on the relative two jiaos low bank of earth between fields in rice field, and water inlet and discharge outlet use steel wire or iron railings
Column is surrounded；
2) rice field sterilization and fertilising, put before seedling ditch cleaning sterilization in 15 days, the surface dust in annular ditch and field ditch are removed, to collapsing
The furrow bank collapsed is repaired, and is then carried out disinfection with the ㎡ of the ㎏ of quick lime 75~90/667 to supporting shrimp ditch and field ditch, then through entering
Mouth of a river water filling is into rice field, after drug toxicity to be sterilized disappears, using the organic manure fermented, and amount of application is every mu 300,000
Gram or so, cultivate foundation bait biological；
3) bait is raised together with, and the vegetal baits such as hydrilla verticillata, Eichhornia crassipes pasture and water are transplanted in the foster shrimp ditch of annular and field ditch,
Pasture and water area accounts for the 30~50% of irrigation canals and ditches area, and the animal baits such as spiral shell are delivered in rice field, make it naturally numerous in irrigation canals and ditches
Grow, injected volume is 200~300,000 grams/acre；
4) shrimp seedling deliver, after in May, paddy rice is transplanted seedlings, deliver specification for 2~4 centimetres the tail of young shrimp 1500~2000/
Mu or 30 kgs/acre, the release time select in fine day morning or overcast and rainy dispensing；
5) shrimp seedling was fed, and the 1st week of shrimp seedling dispensing, is fed the soya-bean milk ground, is fed 3~4 times daily, since the 2nd week, with
Feed the small fish of chopping, spiral shell freshwater mussel meat, butcher based on the animal fodders such as leftover bits and pieces or shrimp seedling special compound feed, appropriate collocation
Multivitamin is added in the pasty fish food that the co-grindings such as corn, wheat, fresh and tender plant stem-leaf are processed into, feed, is immunized many
Sugar, early, evening respectively feeds 1 time, fed with evening based on, account for the 70% of daily ration of feeding, feed 0.25 early stage every ten thousand tail young shrimp day~
0.4 kilogram, later by 10% or so determination day feeding volume of shrimp body weight in pond, during shrimp seed rearing, change water 1 within every 7~10 days
It is secondary, water 20~30% is changed every time, uses within every 15~20 days the content of calcium ion in a quick lime regulating water quality and increase water, with
Shrimp seedling degenerate cllipticity is met to calcareous demand, the consumption of quick lime is 10,000 grams/acre or so, method is to be watered the full pond of slurrying to sprinkle
Spill；
6) field management, carries out water quality management in 8~September part high temperature season, changes 1 water within every 10 days, water 1/3 is changed every time,
Splash within every 20 days 1 lime water regulating water quality, daily management is patrolled field and checked once daily, carries out the anti-escape work of flood control, maintain
There is more water plant in shrimp ditch, lazy weight will in time be mended and put, and should not be washed by water during shrimp shell, increase after shell and feed high-quality animal
Property feed；
7) fished for into shrimp, before and after October, when mercury dropped is to 18 DEG C, increase the harvesting dynamics of cray, such as paddy rice also
Without maturation, then using the method harvesting for discharging water, washing by water, the morning good netting gear on daytime is generally selected, is then discharged water, is allowed and treat absolutely
Most of cray enters in networking naturally with water, is washed by water again several times after water is dry, cray and fish are tracked down and recovered together.
Beneficial effects of the present invention are：The present invention is by can synchronization gain aquaculture in rice field by cray Collocation cultivation
Income, increase the income of peasant household, on the one hand increase can prey on grasshopper insect and aquatic for the cray that is grown in rice field
Harmful organism, on the other hand, the fallen flowers of spike of rice can as cray food intake, improve the meat taste of cray.
