Abstract
The invention discloses a kind of rice shrimp aquaculture method of high content astaxanthin, it is characterised in that including following aspect：（1）Soil treatment, applies and spills farm manure, is handled using Ah's rhzomorph；（2）Rice shrimp aquaculture field, is divided into cultivation guard dam, rice shrimp aquaculture ditch, paddy fields, and is protected with two layers of nylon wire, reduces rice shrimp and escapes；（3）Pasture and water are transplanted, according to the amount of water surface area 25% 30%, transplant pasture and water；（4）Shrimp seedling is delivered, and selects 2 4cm shrimp seedling, and every mu of 2,400 2800 tails of dispensing regularly replace rice field reclaimed water, and increase water oxygen content using water pump；（5）Feeding management, prepares rice shrimp feed, delivers forage volume according to growth phase, and applied using many bacterium biological agents and spill rice field；This method is prepared and feeding method by rice shrimp feed, improves water quality of paddy field environment, and content astaxanthin in rice shrimp can be promoted to improve, while improving rice shrimp aquaculture and rice yield, the inventive method is simple, practical, effect is obvious.
Description
Technical field
The invention belongs to technical field of agricultural breeding, and in particular to a kind of rice shrimp aquaculture method of high content astaxanthin.
Background technology
Cray, also referred to as Procambius clarkii, red crayfish and freshwater crayfish, with pasture and water, algae, aquatic insect, animal corpse
Body etc. is that magnesium has important adjustment effect to cardiomotility, can protect the heart also rich in magnesium, zinc, iodine, selenium etc. in food, shrimp
Vascular system, moreover it is possible to coronary artery dilator, is conducive to preventing hypertension and miocardial infarction；Contain astaxanthin in cray, be one
Very strong antioxidant is planted, with effects such as inoxidizability, antitumor, pre- anti-cancer, strengthen immunity, improvement eyesights, is promoted
The tide of third time preventive medicine.Cray does not produce astaxanthin in itself, mainly passes through food chain --- edible microalgae
Class etc. gets astaxanthin, and constantly accumulation produces superpower oxidation resistance in vivo.When propagating artificially, feed is fed with wheat
Bran, fish meal, peanut cake and shell powder are staple food, and more calcareous composition is contained in fish meal and clam shell, but content astaxanthin is very
It is few, it is impossible to meet the demand in cray breeding process.Paddy field aquaculture pattern, transplants Eichhornia crassipes, water peanut etc. in rice field
Pasture and water, are conducive to improving astaxanthin composition in cray and improve, but the pasture and water such as Eichhornia crassipes, water peanut and feeding feed Prawn
Blue or green cellulose content is few, it is also difficult to meet cray demand；And paddy field cultivation soil, organic principle in soil and it is dispersed in water
Feed organic principle, decomposes ammonification, ammonia-nitrogen content in water is increased, water body easily occurs eutrophication, poison is caused to cray
Evil effect.
The content of the invention
The problem of present invention is directed to existing：Culturing pool breeding way, feeds feed with wheat bran, fish meal, peanut cake and clam shell
Based on powder, more calcareous composition is contained in fish meal and clam shell, but content astaxanthin is limited.Paddy field aquaculture mode, transplants phoenix eyes
The pasture and water such as lotus, water peanut, but content astaxanthin is few in the pasture and water such as Eichhornia crassipes, water peanut and feeding feed, it is also difficult to meet
Cray demand, feedstuff feeding mode is rough, and feed waste is big, and rice shrimp assimilation effect is poor；Due in paddy soil and in feed
Containing a large amount of organic principles, decomposed in water and produce ammonia, it is soluble in water to improve ammonia-nitrogen content in water, make water eutrophication,
Limit the growth of cray.To solve the above problems, the invention provides a kind of rice shrimp aquaculture method of high content astaxanthin.
The present invention is achieved by the following technical solutions：
A kind of rice shrimp aquaculture method of high content astaxanthin, comprises the following steps：
（1）Soil treatment：After the field summer harvest of rice shrimp aquaculture, applied according to every mu of 350-380kg amount in farm organic fertilizer, increase soil
Fertility；After turning over, soil is sprayed using 1.8% AVM, 1200 times of dilutions, dried 11-13 days, soil is carried out
Sterilization and desinsection processing；
（2）Rice shrimp aquaculture field：Paddy field aquaculture field is divided into cultivation guard dam, rice shrimp aquaculture ditch, paddy fields, wherein cultivation protection
Dam plays retaining and prevents the escape of rice shrimp from acting on, and cultivation ditch is arranged at paddy fields surrounding, and planting area Relatively centralized is easy to
Rice Cropping is managed；Its semilate rice shrimp aquaculture ditch is connected with both sides inlet channel and gutter, and gutter is each provided with 1 with inlet channel
Water pump, changes the water in rice shrimp aquaculture field in time, reduces organic principle in water and accumulates, prevents eutrophication；Guard dam is cultivated with supporting
Grow between ditch, there is the nylon separation net of two layers of mesh 40, net high 0.8-1m, reduce the escape of rice shrimp；
（3）Pasture and water are transplanted：Rice shrimp aquaculture ditch, cultivation guard dam are sprayed using 40ppm ClO 2 solutions, after drying 5-7 days,
Sterilization processing is carried out to rice shrimp aquaculture ditch and cultivation guard dam, to cultivation field inner canister water, water surface elevation is 6-9cm；According to rice shrimp
Ditch water surface area 25%-30% amount is cultivated, pasture and water are transplanted, pasture and water can increase lobster adaptability and food, property can block by different level
Sunlight irradiates；
（4）Shrimp seedling is delivered：In 6-7 months, the shrimp seedling that selection size is 2-4cm is delivered according to every mu of 2400-2800 tail, delivered
