Description
?
Technical field:
The present invention relates generally to the method for the Procambius clarkii that a kind of paddy field aquaculture replenishes the calcium.
Background technology:
Cray is the shellfish that survives in a kind of picture lobster in the fresh water, and the formal name used at school Procambius clarkii also is red crayfish or freshwater crayfish.The Northeast claims perverse mqb.Procambius clarkii is the widest exotic invasive species that distribute in the shell-fish.Procambius clarkii forms absolute competitive advantage by force because of its omnivorousness, fast growth, adaptive capacity in local ecotope.Its scope of ingesting comprises pasture and water, algae, aquatic insect, spoil etc., and food is deficient also kills each other when scarce.Procambius clarkii has become important economic breed variety in China in recent years.
How only to pay attention to during existing lobster is cultured under condition cheaply, improving the output of lobster, can't pay attention to the quality of lobster, also can not pay attention to the nutrition supply degree of lobster human body.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of prior art, and the method for the Procambius clarkii that a kind of paddy field aquaculture replenishes the calcium is provided, and supplementing calcium element when Procambius clarkii is cultured is highly profitable to the healthy of crowd of calcium deficiency.
The present invention realizes through following technical scheme:
The method of the Procambius clarkii that a kind of paddy field aquaculture is replenished the calcium is characterized in that: the cultural technique step is following:
One, the transformation in rice field and construction:
Heightening and consolidation is carried out to this rice field ridge in selected rice field of culturing Procambius clarkii, and ridge height is exceeded more than the 40cm of plane, rice field, and the ridge is wide about 100cm;
Excavation supplies the shrimp ditch that Procambius clarkii is movable, avoid heat and look for food in the rice field, shrimp furrow width 1m, and about shrimp ditch depth 0.8m, the area of shrimp ditch accounts for about 10% of rice field area;
The anti-facility of escaping is set around in the rice field;
Two, cleaning sterilization: handle being elected to be the field that carries out disinfection clearly, the rice field of supporting shrimp at the beginning of by the end of April to 5 months, during detoxicating, in the rice field, pour water 10 centimetres earlier, promptly the shrimp ditch depth of water is about 90 centimetres, splashes with the complete while hot field of 30～40 gram lime waters by every square metre then;
Three, the rational application of fertilizer: during fertilising, to the rice field: execute 25 kilograms of carbon ammoniums for every mu, 20 kilograms of superphosphate, 50 kilograms of fresh hay wood ashes; Prawn ditch: use farmyard manure 50～100 loads of becoming thoroughly decomposed for every mu;
Four, rice transplanting in good time: rice transplanting period is late May; The density of rice transplanting is: about 13 centimetres of spacing in the rows, about 23 centimetres of line-spacings; During rice transplanting, by about 2 meters separated position, stay the railway carriage or compartment row one, the distance of railway carriage or compartment row is about 30 centimetres;
Five, in the shrimp ditch, throw in beneficial organism: every square metre of shrimp ditch water surface is thrown in 0.3～0.5 kilogram of silk earthworm; Every square metre of shrimp ditch water surface is thrown in 8～10 river snails; Every square metre of ditch water surface is thrown in 3～4 freshwater mussels;
Six, in the shrimp ditch, throw in branch and transplant water plants: water plants is wanted every interval to put for 2～3 meters when transplanting to plant one, and every area is about 1 square metre;
Seven, throw in the shrimp seedling: at 5～7 days input shrimp seedlings in the rice field after the rice transplanting, every mu of area is thrown in 50 kilograms of shrimp seedlings;
Eight, throw in the shrimp food: select spiral shell, mussel meat, small fish, shrimp, earthworm, livestock and poultry to butcher offcuts, sunflower seed grouts, bran, green grass, dish leaf, p.malaianus, wolffia arrhiza, red duckweed and weter hyacinth etc. as feed; Feed of animal origin and vegetable feed are suitable basically, and the forage volume of throwing something and feeding every day accounts for the 5-8% of pond Prawn TBW; Described input feed divides the upper and lower noon twice, accounts for the 25-35% of whole day feeding volume the morning, accounts for 65-75% afternoon;
Every at a distance from sterilization growth accelerator of input in 3-5 days, injected volume is the 3-5% of shrimp feed weight on the same day; The sterilization growth accelerator is pulverized formulated by following raw materials according by weight:
Calcium dihydrogen phosphate 2-4, green tea powder 4-5, black soya bean powder 10-12, lysine 0.5-0.8, betain 1-2, hawthorn 6-7, hypericum japonicum 4-5, Divine Comedy 10-12, david woodbetony rhizome 10-12, garlic powder 10-12, withy 10-12, bone meal 1-3; Calcium lactate 5-8, sodium Diacetate 0.5-1, oyster shell powder 4-5;
Nine, sterilization
The shrimp ditch water surface was changed water and is splashed in the food field with bleaching powder sterilization 1-2 time in every month; In the prawn disease epidemic season, disinfectant adopts bleaching powder, the white ash of giving birth to;
Ten, fish for into shrimp.
The sterilization growth accelerator is pulverized formulated by following raw materials according by weight:
Calcium dihydrogen phosphate 3, green tea powder 4, black soya bean powder 11, lysine 0.5, betain 1, hawthorn 7, hypericum japonicum 4, Divine Comedy 10, david woodbetony rhizome 10, garlic powder 12, withy 12, bone meal 3; Calcium lactate 6, sodium Diacetate 0.5, oyster shell powder 5.
Said rice field ridge combines the transformation in rice field to carry out heightening and consolidation in should be in the winter time.The stalk height generally exceeds the plane, paddy field more than 40 centimetres, obstructs wide about 100 centimetres.Ridge widen increase after, tamp and fasten, guarantee that ridge is water-tight.As the old dykes and dams that close water, answer uproot weeds, the stifled hole of killing mouse for the limit, field.
The excavation shrimp will take the circumstances into consideration to dig the 1-3 bar according to the size of field piece during ditch.1 meter of furrow width, about 0.8 meter of ditch depth.The earth of excavation shrimp ditch, peripheral can get rid of on ridge, and middle just evenly looses in Tanaka.The area of shrimp ditch generally accounts for about 10% of rice field area.
The advancing to arrange facility and should combine to excavate the shrimp ditch and take all factors into consideration of rice field, excavation advances escape canal should combine the excavation utilization with the shrimp ditch.Build for the retaining ditch in the external world or the excavation in drain ditch, be Yu Yaoshui and promptly irritate, change and promptly to arrange.
During detoxicating, in the rice field, pour water 10 centimetres earlier, promptly the shrimp ditch depth of water is about 90 centimetres, splashes with the complete while hot field of 30～40 gram lime waters by every square metre then.When splashing, the shrimp ditch will be laid particular stress on.
As the rice field of culturing Procambius clarkii, should be in whole field in the first tenday period of a month in May, cultivated adjusting method can adopt traditional Niu Gengniu rake, and it is whole also can to adopt modern machinery to plough.The rational application of fertilizer is wanted after putting in order well in the rice field, should adopt two kinds of diverse ways to rice field and shrimp ditch during fertilising.Rice field: execute 25 kilograms of carbon ammoniums for every mu, 20 kilograms of superphosphate, 50 kilograms of fresh hay wood ashes (can not use potassium chloride); Shrimp ditch: use farmyard manure 50～100 loads of becoming thoroughly decomposed for every mu.
Best period is late May during rice transplanting.The density of rice transplanting should be rarer than the rice transplanting of conventional semilate rice, and promptly spacing in the rows is about 13 centimetres, about 23 centimetres of line-spacings.During rice transplanting, also must stay the railway carriage or compartment row one by about 2 meters separated position.The distance of railway carriage or compartment row is about 30 centimetres.Open preferably north-south of railway carriage or compartment direction, in order to the rice field ventilation and penetrating light.
Culture the rice field of Procambius clarkii, should in the shrimp ditch, have a mind to throw in a little beneficial organisms, like water silk earthworm, river snail and freshwater mussel or the like.Through increasing the live bait in the water body and utilizing beneficial organism to purify water.Every square metre of shrimp ditch of water silk earthworm is thrown in 0.3～0.5 kilogram; Every square metre of shrimp ditch of river snail water surface is thrown in 8～10; Every square metre of ditch water surface of freshwater mussel is thrown in 3～4.The individuality of freshwater mussel is not thrown in excessive, general every weight between 100～200 grams for well.
Be intended to throw in a little branches in the shrimp ditch and transplant a spot of water plants.Movable for the ease of Procambius clarkii, perch and defend harmful animal, in the shrimp ditch, can throw in things such as a little branches and branch of lycium chinensis mill in right amount, and transplant the water plants that a spot of Procambius clarkii does not eat.Water plants is wanted every interval to put for 2～3 meters when transplanting to plant one, and every area should be must guard against full ditch and throw in about 1 square metre, in order to avoid influence normally looking for food and activity of lobster.
Generally after rice transplanting 5～7 days, treat to throw in seed when rice shoot is turned green, throw in density and should support shrimp than the pond and throw seedling and lack 40%, be i.e. 50 kilograms of every mu of area inputs, about 8000～10000 tails.
To note 3 points when throwing in the shrimp seedling: the one, be chosen in sooner or later or overcast and rainy throwing seedling, in order to avoid the harm of the shrimp seedling generation temperature difference; The 2nd, evenly get an input along the shrimp ditch, in order to avoid the shrimp seedling is too concentrated, local water body severe depletion of oxygen and cause shrimp seedling death by suffocation; The 3rd, should not be at the strong input shrimp seedling during with high temperature of sunlight.
There are the biology of many procreations at different levels naturally and pasture and water to supply Procambius clarkii edible though culture the rice field of Procambius clarkii; But; Because the breeding density of Ke Shi crayfish is bigger in the rice field; Along with the continuous growth growth of Ke Shi crayfish body weight, the natural food in the rice field just can not satisfy the Procambius clarkii demand far away.Therefore, in the rice field of culturing Procambius clarkii, the shrimp food that the manual manufacture of often throwing something and feeding goes out promotes the quick growth of Procambius clarkii to satisfy Procambius clarkii demand to food in process of growth.
Shrimp is supported when feeding in the rice field, and it is the same to support shrimp with the pond, change according to weather condition, determines feeding number of times and feeding amount flexibly.As blow hard, following wet weather or heavy rain, cold air such as go down south at weather, and can reduce the feeding number of times as one sees fit or reduce the feeding amount, during bad weather, can not feeding.
Advantage of the present invention is:
The sterilization growth accelerator has multiple functions such as sterilization, growth promotion, increase shrimp premunition, can effectively prevent prawn disease to take place, and improves survival rate, and the shrimp growth is fast.
The inventive method is cultured step according to the life habit arrangement of lobster, has improved the output of lobster, and lobster is edible can improve its shrimp food of calcium constituent on one's body through making, and the healthy of crowd of calcium deficiency is highly profitable.
