Description
Technical field
The present invention relates to a kind of cray cultural method, specifically a kind of method of paddy field aquaculture cray.
Background technology
Cray is also referred to as Procambius clarkii, red crayfish and freshwater crayfish, is economic freshwater shrimps, because meat flavour it is delicious extensively by
People welcome, and cray has become Important Economic breed variety, market price more and more higher in China in recent years, and demand is got over
Come bigger, so as to drive the development of artificial farming, paddy field aquaculture cray is less at present, because cultural method is with improper, production
The lobster individual gone out is small, and meat is poor, survival rate bottom, so that raiser's income step-down, while artificial feeding feed is more, not only increases
Aquaculture cost is added, and has made lobster degradation, do not sold good price, some raisers are used excessively, no agriculture chemical
Only make lobster Quality Down, also pollute water resource and soil, be unfavorable for sustainable development.
The content of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide a kind of cray to cultivate field
A kind of paddy field aquaculture cray method.
In order to solve the above technical problems, the invention provides following technical scheme：
A kind of method that cray is supported in rice field, is comprised the following steps that：
(1) field is selected：Selection is had abundant water resources, good pollution-free, the fertile soil of water quality, good water-retaining property, dry season easy water transfer, rain
Season easy draining, the sufficient field of illumination.
(2) field is transformed：It is 2~3 meters to dig width at 1 meter on the inside of from rice field surrounding ridge, and depth is 0.7~1.2 meter,
Support shrimp ditch in the ring field that 50~70 degree or so of the gradient；Then made of the pan soil digging out along foster shrimp ditch periphery and enclose the ridge, it is highly 0.6 to enclose the ridge
~0.8 meter, width is 1~1.5 meter；Then ridge is tamped, the anti-escape of high 40~50 centimetres of twice is set in ridge surrounding
30 cms in ridge soil are inserted in net, anti-escape network lower end；10~15 days before shrimp species are put, every mu of foster shrimp ditch quick lime or
Bleaching powder 50kg, thorough disinfection, killing harmful living and pathogenic bacteria are carried out to supporting shrimp ditch；Put before shrimp 7 days, to supporting shrimp ditch water filling
40~60 centimetres, then apply 500~600kg of farm manure for every mu, water quality of fostering and apply fertilizer, cultivate natural bait；Planted after fertilising in foster shrimp ditch
The water plant that the crays such as waterweed, eel grass, hydrilla verticillata, water caltrop are liked is planted, natural bait is provided for cray and inhabites
Place.
(3) rice shoot is planted：During the first tenday period of a month in May, in 5~8 centimeters of the paddy fields water filling that foster shrimp ditch surrounds, select resistant to lodging
Ability is strong, the strong middle rice varieties of diseases and insect pests resistance, carries out rice transplanting transplanting, and density of transplants is 5000 plants every mu.
(4) shrimp seedling is put in a suitable place to breed：3~5 days after rice shoot plantation, select survival rate high, specification is that 2~4 centimetres of shrimp seedling is every
Mu launches 5000~8000 tails.
(5) feeding management：Due to the artificial infertile field rich water of early stage, planting aquatic plants, there is provided enough natural baits
Material, need not generally launch particulate material, when if necessary to launch, can launch some small fish, mussel meat and
The animal baits such as earthworm, increase the comprehensive of cray feed, when feeding time is arranged in the dusk 6, once a day, injected volume
For 2 the percent of shrimp body weight, adjustment as the case may be feeds number and feeding volume；In addition to dry field, usually the rice field depth of water should
20 cms are maintained at, and often change water, general 10 points or so the progress in the morning of rice field water filling, keep diversion water temperature and rice field
Water temperature is close, and wants during water filling to fill in row, accomplishes that the temperature difference is little, change water weekly once by the end of June, quantity of exchanged water 1/4th or so,
7~August part, changes weekly water 3~4 times, quantity of exchanged water 1/3rd or so, after September part, changes water once within every 5~10 days, quantity of exchanged water three
/ mono-；Support and be spilled once in shrimp ditch with lime water within every 15~20 days, each every mu of dosage is 5~10kg, and water is killed
Bacterium, increase water quality；Spray insecticide if desired, selection is efficient, low toxicity, the agricultural chemicals of low-residual, reduces the harm to cray.
(6) field daily management：Daily management, it is careful and responsible, unremittingly, adhere to that each inspection is once sooner or later daily,
Special rainy day, increase inspection number and duration, the main situation of change for checking water level and water quality of inspection, the feed feelings of cray
Condition and health status, the upgrowth situation of the seedlings of cereal crops, pinpoint the problems in time and make corresponding processing, while carry out emergency processing
Prediction scheme, it is easy to the timely reaction of emergency case, reduces property loss.
(7) caught into shrimp：The shrimp seedling that May launches, 7, August part ripe can catch, during fishing with lobster basket, cage net or
Person's fishing net is caught.
As the further improvement project of the present invention：It is described put in a suitable place to breed in shrimp seedling launch shrimp seedling when should select fine day morning or
Rainy days, avoid direct sunlight.
As further improvement project of the invention：Rice leaf is sprayed when being sprayed insecticide in the feeding management, to the greatest extent
Amount is not sprayed into water.
As further improvement project of the invention：Alien species are expelled in the field daily management, than
Domestic duck is such as forbidden to enter field ditch.
As further improvement project of the invention：Take to catch in the fishing into shrimp and stay small method greatly, do not reach
Listing requirements continue to raise.
Compared with prior art, the beneficial effects of the invention are as follows：
The shrimp rice continuous cropping of the present invention, promotes planting industry and the combination of aquaculture, makes to be formed between shrimp and rice benign
The ecological cogeneration system of circulation, is advantageous to economize on resources, and improves the utilization rate of resource, can not only improve rice yield and quality,
And the harvest yield of shrimp is added, while reduce the use of fertilizer and pesticide, contribute to sustainable development.
