Abstract

The invention discloses a novel efficient and low-carbon ecological breeding method. Plants, animals, the planting industry and the breeding industry are organically combined, the virtuous cycle of substances and energy of a pond ecological system is kept well, the optimum mode of harvesting shrimps and siniperca chuatsi in two seasons of one year is achieved, and therefore the space of a unit water body and the time are reasonably and fully utilized. The utilization rate is improved through conversion of the food chain, the production cost is saved, the pollution is reduced, the ecological environment of a pond is improved, and therefore the novel efficient and low-carbon ecological breeding method is worthy of wide popularization.

Description

A kind of new and effective low-carbon ecological cultural method

Technical field

The present invention relates generally to a kind of cultural method, relates in particular to a kind of new and effective low-carbon ecological cultural method.

Background technology

Low-carbon (LC) fishery, ecological fishery are the directions of domestic and international Fisheries Development, this project fully utilizes the relation between different Food chains, in pond, plant perennial ryegrass season in winter slack, when April next year, Procambius clarkii is put in water filling in a suitable place to breed, the ight soil of Procambius clarkii is cultivated plankton with eating after surplus grass rots, then put silver carp in a suitable place to breed, bighead summer flower goes the plankton that ingests, then the mandarin fish seed of putting appropriate specification in a suitable place to breed go to ingest silver carp, bighead seedling, and the bed mud of deposition is the organic manure of winter planting perennial ryegrass.When improving breeding water body environment, also for cultivation object provides abundant natural bait, improved the quality of Procambius clarkii and mandarin fish.

By the transformation of Food chain, upper link biology, residue or a metabolic waste are become to the feed of next link biology by biological transformation, reached the object of efficient ecological cultivation, Plants and Animals, plant husbandry and aquaculture are combined, integrated innovation has formed " perennial ryegrass-Procambius clarkii-forage fiss-mandarin fish " efficient ecological aquaculture model, realize Procambius clarkii and mandarin fish bumper harvests, solved in current aquaculture the problem such as pond waters is seriously polluted, siltation is many, yield poorly down, disease takes place frequently.

In production practices, sum up " perennial ryegrass planting technology ", " Procambius clarkii cultural technique ", " flower silver carp spray cultural technique ", " mandarin fish cultural technique ", by food chain, carry out organic assembling, and to these technology carry out integrated with optimize, rationally utilized time and space, reach best ecological benefits and economic benefit.In this cyclic culture pattern, the biology of previous link or residue refuse are used as natural bait by next link biology again, energy flow is recycled in food chain, realized the benign cycle of pond ecosystem material and energy, this high-efficiency low-carbon ecologic breeding pattern is to improve a kind of new production system of unit water surface benefit, plant, animal, plant husbandry and aquaculture are combined, realize shrimp, mandarin fish bumper harvests, the high effective model in 1 year two season.

Summary of the invention

The object of the invention is just to provide a kind of new and effective low-carbon ecological cultural method.

The present invention is achieved by the following technical solutions:

A low-carbon ecological cultural method, comprises the following steps:

(1) clean up the pond, ditching

Drain Chi Shui annual November, every mu with full pool spilling head after 90-100 kilogram of quicklime water, eliminate noxious bacteria and wild fishes class in pond, in pond, dig out ' well ' font, the ditch of dark 25-35 centimetre, be convenient to drain the moisture content in Pond Silt, when mud is half-dried, just sow rye grass seeds, every mu with kind of a 2-3 kilogram;

(2) shrimp seedling is put in a suitable place to breed

In annual March, to water filling in pond, flood green grass or young crops, water filling 15-25 centimetre for the first time, water can not cover perennial ryegrass, during water filling, with 40-60 order mesh bag, filter, remove foreign material and fishes and shrimps in water, throw in lobster seedling 15-30 kilogram for every mu, later along with growing tall of perennial ryegrass added water once every 7-10 days, constantly, for shrimp seedling provides bait and playground, the lobster that reaches listing specification to mid-May can catch and list marketing;

(3) fry is put in a suitable place to breed

In late May, throw in the flower silver carp fry of breeding then, every mu of 400,000 tails, can be according to the water colour situation soya-bean milk of throwing something and feeding;

(4) mandarin fish is put in a suitable place to breed

When flower silver carp fry grows to more than 2 centimetres, just can throw in 5 centimetres of mandarin fish seedlings that left and right is large, put 180-250 tail in a suitable place to breed for every mu, through the cultivation of more than four months, just can list marketing about November, mandarin fish reached 0.6 kilogram/tail.

Advantage of the present invention is:

This efficient ecological aquaculture model of the present invention is feasible and rational completely, plant, animal, plant husbandry and aquaculture are combined, the benign cycle that keeps better pond ecosystem material and energy, realize the two receipts of shrimp mandarin fish, the optimal mode in 1 year two season, rationally make full use of the room and time of unit of water body, conversion by food chain has improved availability, saved production cost, reduced pollution, having improved the ecotope in pond, is a kind of new and effective low-carbon ecological aquaculture model being worth promoting very much.
