Description

A kind of freshwater crayfish paddy field Eco-breeding pattern
Technical field
The present invention relates to cultural technique field, more particularly to a kind of freshwater crayfish paddy field Eco-breeding pattern.
Background technology
Freshwater crayfish, scientific name Procambius clarkii (Procambarusclarkii) is a kind of shrimp for having much economic value Class.Cray is cultivated in rice field, is that planting industry is combined with aquaculture, the ecosystem manually built is made full use of System, makes cray and paddy rice mutualism.Cray can remove weeds, insect in rice field, while its excreta and residual bait can Utilized for paddy growth;And paddy rice can provide abundant natural bait and good habitat for cray, the two is reciprocal It is mutually beneficial.
The content of the invention
It is simple, with low cost that the technical problems to be solved by the invention are to provide a kind of method, can give full play to farmland Productivity, improves the freshwater crayfish rice field ecology aquaculture model for the economic benefit that farmland is managed.
The technical scheme that the present invention solves above-mentioned technical problem is as follows:A kind of freshwater crayfish paddy field Eco-breeding pattern, Comprise the following steps:Rice field is selected and transformation;Cultivate early-stage preparations;Freshwater crayfish seed is delivered;Rice Cropping;Raise pipe Reason.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the rice field selection and the technical essential transformed are as follows:
Rice field requires convenient into draining, is not influenceed, had abundant water resources by drought, big flood, water quality is pure and fresh pollution-free, and physical and chemical index meets Water quality standard for fishery, fertile soil, water retention property are good, sunny, and area is in 0.4 hm2More than;
In rice field, surrounding builds the main ridge, it is desirable to which more than the m of top width 2, high 1.0~1.5 m, slope ratio is l:2~1:3, the larger rice of area Field, is divided into 0.25hm2Following small field, while the ridge building in the middle of field, builds ridge only one end and is connected with the main ridge, Below 1m locates on the inside of away from the main ridge and ridge, digs 4~7 m one wide, depth 1.2m annular shrimp ditch along the ridge, shrimp ditch from water inlet end to There is certain inclination water side;
Improved rice field, ridge, shrimp ditch, the area ratio generally 1 of paddy fields:2:7, enter discharge outlet and be arranged in rice field phase To on two jiaos of the main ridge, if blocking shrimp net.
Further, the technical essential of the cultivation early-stage preparations is as follows:
On the inside of the main ridge, buried away from the ditch that depth a below 20cm is dug at ridge inclined-plane 0.5m, then by one end of reinforced plastics film In people's ditch, with soil pressure is tight, compacting, reinforced plastics film normal is supported and fixed with bamboo paper tinsel or small wooden, it is ensured that modeling Material film is higher by 40~50cm of ridge face;
Stay water O.2m following during sterilization, in shrimp ditch, carried out disinfection with quick lime;
Every mu using pig manure, the chicken manure organic fertilizer 400kg by fully fermenting;
Pasture and water, waterweed, eel grass and spray plant are planted in shrimp ditch, pasture and water planted area will account for more than the 1/3 of total water surface, Early spring, every mu of dispensing 50kg spiral shell.
Further, the technical essential that the freshwater crayfish seed is delivered is as follows:
Seed size is arranged in annual mid-March to mid-April in 140 tails/kg, every mu of about 45 kg of dispensing, release time, or Early November to mid-December.
Further, the technical essential of the Rice Cropping is as follows:
The shrimp Tanaka suitable growth selection phase is longer, the hard non-lodging of stem, resistance to fertilizer, the rice varieties that premunition is strong, yield is high;
Using large-ridge double-row cultivating technology, i.e., every 2 behavior l groups, the interior line-spacing of group is 20cm, and group spacing is 40cm, is transplanted seedlings the time one As in late June.
Further, the technical essential of the feeding management is as follows:
The cray mixed feed of high-quality is fed, it is the 2~6% of shrimp gross weight that day, which throws feeding amount, and the early spring, late autumn low temperature season are daily Afternoon 17:00 feeds once, summer high-temperature season daily 8:00、17:00 respectively feeds once, and feeding volume is respectively day to throw feeding amount 30~70%;
Refreshed the water periodically according to weather and water quality situation, water 1/5, high temperature season, every 15~20 d, every mu of oyster of use 3~7 are changed every time Quick lime water is splashed, when water body is thin, using fermented muck rich water, is given birth to during water quality overfertilization with EM bacterium, photosynthetic bacteria Thing preparation improves water quality;
Three blooms are added in feed, high temperature season adds liver and gall Li Kang in feed and dissipates Chinese herbal and crude drugs preparations;
Short dung, and timing weeding, disease prevention can be added in good time according to the growing way of paddy rice.
The beneficial effects of the invention are as follows:Method is simple, with low cost, using cray rice field ecology aquaculture model, can be by Cray cultivation combines with Rice Cropping, makes the two mutualism, gives full play to the productivity in farmland, improves farmland The economic benefit of operation.
Embodiment
The principle and feature of the present invention are described below in conjunction with example, the given examples are served only to explain the present invention, and It is non-to be used to limit the scope of the present invention.
