Description
Technical field
The present invention relates to aquaculture technical fields, and in particular to a kind of cultural method that rice shrimp educates altogether.
Background technique
Procambius clarkii, also known as cray are one of highly important freshwater aquiculture kinds in China.Its delicious meat, battalion
It supports and enriches, there is very high experience value, be favored by people, cultured output in recent years is also increasing.
Currently, more and more people begin trying ecologic breeding, for example cray is cultivated in rice field, the side of this mixed breeding
Formula is that planting industry and aquaculture are combined, and makes full use of the ecosystem manually built, and keeps cray mutual with rice
Sharp symbiosis.It not only can be with increasing both production and income；And cray can eat up the wild weeds and aquatile of Tanaka, without eating rice seedlings, also
The harmfulness larva including mosquito can be eliminated, weeding can be played the role of and removed the evil；Third is that fish, shrimp travelling, looking for food facilitates rice
Field loosens the soil, running water, ventilation, can increase water in field dissolved oxygen amount, while a large amount of excrement are discharged by metabolism, play the effect of getting fat
Fruit.
But since the lobster busy season is generally all in summer and autumn, winter and spring since weather problems lead to growth of seedling
It is relatively slow, or can not be bred, so more rare or second-rate with the cray in spring in winter, head is smaller.
Summary of the invention
It is an object of the present invention in view of the above shortcomings of the prior art, propose a kind of cultural method that rice shrimp educates altogether, lead to
The cray for crossing this method cultivation can not only guarantee big specification and high-quality, and can list ahead of time, at this time cray city
Field price is rather stiff, can obtain higher economic benefit of aquaculture.
A kind of cultural method that rice shrimp educates altogether proposed by the present invention, includes the following steps,
Step 1, cultivate pond early stage to cultivate: August part the middle ten days and the last ten days selects physically fit, hard shell bright red, weight 30-60g, abdomen tail
The shrimp that portion's muscle is full, gonad development is good is thrown to as parent and cultivates pond, launches 60-100Kg per acre, male and female number ratio is
3-4:1；
Step 2, greenhouse reinforced cultivating and breeding: October, temperature are gradually reduced, and select constitution from cultivating in pond
It is healthy and strong, carry out reinforced cultivating without hurting disease-free parent and be put into transparent heat insulating greenhouse, 40-60Kg, male and female number ratio are launched in every pond
2:1；70% plant feed and 30% animal fodder are fed, close shrimp is gradually induced to mate, breed in greenhouse；
Step 3, shrimp seed rearing: parent post-coitum when finding a large amount of shrimp seedlings, should catch parent in time, until whole parents are caught
Fishing retains shrimp seedling and continues to cultivate in greenhouse, and shrimp seedling stocking rate is every square metre of 180-220 tail, first week after putting in a suitable place to breed, throws
Soya-bean milk is fed, is fed 3-4 times daily, each feeding volume is every ten thousand tails shrimp seedling, 0.2 Kg；The animality that second week starts to feed 80% is raised
Material and 20% plant feed, respectively feed 1 time sooner or later, and evening feeding volume is the 70% of one day feeding volume, and day feeding volume is every ten thousand
0.4 Kg of tail shrimp seedling；It feeds and is cultivated by 15% of shrimp weight in pond later.
Step 4, rice field is transplanted seedlings: select two season rice or triple cropping of rice planting area carry out shrimp rice and educate altogether, first basis before transplanting seedlings
Greenhouse temperature of cultivation is adjusted in water temperature in rice field, and water temperature gradient in greenhouse is adjusted to rice field water by 5-7 days
Temperature after lower water temperature is consistent, cultivates 3-5 days under the water temperature；Seedling is shifted again, shrimp seedling shift specification be 50~150 tails/
Kg, shrimp seedling breeding density are 3000~5000 tails/mu, daily feeding organic feed twice, respectively in morning 7:00-8:00 and
17:00- 18:00, each injected volume are the 4%-6% of shrimp seedling total weight.
Since temperature slowly turns cold after autumn, water temperature is lower in rice field outside greenhouse, and it is that can not adapt to that shrimp seedling, which directly shifts,
, it may appear that the phenomenon that mortality, so the water temperature in greenhouse is gradually reduced, adapt to shrimp seedling slowly, thus
It can ensure that the survival rate of shrimp seedling after shifting significantly.
Further, cultivation pond described in step 1 is surrounded by ring-shaped groove, and centre is equipped with shoal, the culture pond
8-12 mus of pool surface product, length-width ratio is advisable for 2:1.Circular groove area accounts for the pond gross area 30% or so.Be conducive in this way plant water plant,
Conveniently feeding, controlling is suitable for water level etc..
Soil property requires glutinous loam first, cannot be sandy soil or loose soil property, sandy soil is easy to collapse, because of cray
Like burrowing, a collapsing cray, which will be buried, to die.Then not have water affirmative not all right close to water source.If cray
If culture zone close to the big water surface such as river, lake, reservoir, close to water source this on one side, to carry out anti-escape measure, to widen
Dykes and dams are reinforced, are wanting buried some close nets or plastic film into discharge outlet, because the water flow of the big water surface can stimulate cray to burrow
Escape, climbing escape；Especially some river shoals, lakeshore, can rise in rainy season, rise if it is also better in July, but such as
Fruit is risen in advance, has to carry out the precautionary measures in advance, prevents the unrestrained pool from escaping shrimp.
Further, cultivation has water plant on the shoal, and the area coverage of the cultivation of the water plant is more than or equal to whole
The 65% of a shoal area；The water plant includes waterweed and Ye Heizao, and the plant quantity ratio of the waterweed and Ye Heizao are 2:
1。
Cultivation water plant not only can preferably improve aquatic environment, promote the healthy growth of shrimp, while also avoiding in height
Under the conditions of temperature, water temperature over-high, since Procambius clarkii is to very temperature sensitive, water temperature over-high not only influences the metabolism of shrimp,
It so that it is generated pathogenic bacteria, eventually lead to death.
It is before throwing seedling that water plant kind is good, water planting is good.Cultivating the optimum water plant of cray is waterweed.Because she
Happy algae is cold resistance, generally since annual November can kind, until can plant in 2 months, in this way to 2
When the middle of the month to March, waterweed just grows relatively good, has formed certain advantage, area coverage one in water
As can reach 65% or more, even more, the cray seed of dispensing will not form destructive destruction to waterweed, in 6, July
A hydrilla verticillata is reseeded when part, to take certain precautionary measures when planting hydrilla verticillata certainly, it will be first enclosing beach
It is surrounded with purse seine, cray not allowed to enter growing area in advance, otherwise lobster can press from both sides the tender shoots of drinking water grass, destroy water plant.
Waterweed can overgrow with the rise of temperature, lead to bottom anoxic, subalimentation etc., be at this moment likely to result in water
Grass rots, rotten, and then bad water, leads to that lobster is not long, does not eat food, and disease etc. occurs.So have to excessive waterweed into
A measure is dredged and cut to row once, allows waterweed to be maintained at 20 centimeters of the water surface or so, while keeping water quality pure and fresh, preferably up to clearly
It is clear to see the bottom, but also to have certain fertile degree best on the surface, what waterweed usually will not be dead in this case.When
The area coverage that so also keep waterweed certain, if area coverage is few, nutrient, impurity in water body cannot be absorbed point
Solution, excessive impurity can be attached on the blade face of waterweed, also result in the death of waterweed.
Further, the cultivation pond in step 1 parent launch first 1 month, thoroughly remove in pond, pool ridge weeds and watt
Gravel, pond add water submerged center to enclose beach 20cm, and using lump lime slurrying, full pond is uniformly splashed while hot, use quick lime per acre
150 Kg。
