Description

A kind of method of rice shrimp ecologic breeding
Technical field
The present invention relates to technical field of agricultural breeding, and in particular to a kind of method of rice shrimp ecologic breeding.
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 by People welcome, and cray has become Important Economic breed variety in China in recent years, and the market price is higher and higher, and demand is got over Come it is bigger, to drive the development of artificial breeding.
More and more people begin attempt to ecologic breeding, for example cray is cultivated in rice field, and the mode of this mixed breeding is Planting industry and aquaculture are combined, the ecosystem manually built is made full use of, keeps cray total with rice mutual benefit It is raw；But since cultural method is with improper, the lobster individual of output is small, and meat is poor, survival rate bottom, to make raiser's income become It is low, while artificial feeding feed is more, not only increases aquaculture cost, and make lobster degradation, good price is not sold, some Raiser, using excessively, not only declines lobster quality, also polluted water resource and soil, be unfavorable for sustainable to agriculture chemical Development.
Invention content
(1) the technical issues of solving
The present invention provides a kind of method of rice shrimp ecologic breeding so that the cultivation of cray more rationalizes, environmental protection, warp Jiization and practical, cooperation paddy field aquaculture form the ecological cultivation method of benign cycle.
(2) technical solution used
The present invention to achieve the above object, is achieved by the following technical programs：A kind of method of rice shrimp ecologic breeding, The ecological cultivation method includes the following steps：
(1) rice field prepares：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 easily drains, the field of illumination abundance；
(2) rice field is transformed：Rice field is divided into cultivation guard dam, rice shrimp aquaculture ditch, paddy fields, the rice shrimp aquaculture ditch It is connected to both sides inlet channel and gutter；It is isolated by steel wire between cultivation guard dam and cultivation ditch；
(3) water plant is transplanted：Mud in rice shrimp aquaculture ditch, maintenance dam is cleared up, after drying 3-4 days, is filled into rice field Water transplants water plant later；
(4) shrimp seedling is launched：It is picked as with pathogen, without the strong cray seedling of dipping, disease resistance, per acre pond Launch ten thousand tails of 1.4-1.6；
(5) feeding management：20-30 parts of corn flour, 22-28 parts of Soybean Meal, 14-16 parts of shrimp shell meal, south are weighed according to quality 18-22 parts of melon powder, 30-36 parts of rice bran, 18-30 parts of Haematococcus pluvialis powder；After evenly mixing, by pelleter, it is made 4-6mm The rice shrimp feed of grain；
Rice shrimp feed feeding method：Rice shrimp feed is invested in bait basket, 8-12 days after shrimp seedling dispensing, was thrown per 3-4 days It is primary to put feed, launches 5-8kg every time；Rice shrimp growth medium, per 3-5 days, dispensing feed was primary, each 10-14kg；Rice shrimp gives birth to In the long later stage, per 2-3 days, dispensing feed was primary, each 18-22kg；
(6) lobster is caught：After shrimp seedling is raised 2 months, the lobster that specification is reached to weight is caught in time, reduces lobster Cultivation density promotes lobster fast-growth, can reduce cost, increases yield and improves quality；The variation it is noted that weather is caught, Weather not caught when sultry, at this time weather anoxic, and lobster will be dead in cage, and fishing will put cage more, diligent to receive cage, subtract Time of few lobster in cage, it is ensured that the fresh and alive degree of lobster.
The size of step (2) the semilate rice shrimp aquaculture ditch is as a further optimization of the solution,：Furrow width 1.6-2.0m, Depth 0.8-1.2m.
