Abstract

The invention discloses a culture method for rice field ecological fish culture. The method comprises the following steps: 1) selecting a rice field, 2) processing the rice field, 3) stocking fish fingerling, 4) and breeding and managing. Beneficial effects are that the culture method for rice field ecological fish culture can effectively solve problems that growth speed of fish bodies is slow and yield is low in a rice field fish culture process. The method can ensure water to be clean, and is beneficial for cyclic development.

Description

The cultural method that a kind of rice field ecology is breeded fish

Technical field

The present invention relates to the cultural method that a kind of rice field ecology is breeded fish.

Background technology

Fish live in water all the year round, with gill respiration, assists the alternating temperature vertebrate of balance and motion with fin.The flesh of fish is rich in animal protein and phosphorus matter etc., nutritious, and flavour is delicious, easily digested, has significant role to the development of mankind's muscle power and intelligence.Other parts of fish body can be made into cod-liver oil, fish glue, fish meal etc.There are very long coastline, numerous rivers and lakes in China, and the kind of fish is very abundant.According to investigations, China fresh-water fishes have kind more than 1000, the excellent fresh-water fishes kind that famous " four large Chinese carps " (black carp, grass carp, silver carp, bighead) and carp, crucian Deng Doushi China are main.

Utilize the rice field water surface to breed fish, both can obtain fishery-ies product, fish can be utilized again to eat up insect in rice field and weeds, excretion muck, stir earth and promote manure digestion, for paddy growth creates good conditions, but the most output of existing rice field fish culture technology is not high.

Summary of the invention

Object of the present invention is exactly for above-mentioned defect of the prior art, provides the cultural method that a kind of rice field ecology is breeded fish.

To achieve these goals, technical scheme provided by the invention is: the cultural method that a kind of rice field ecology is breeded fish, and comprises the following steps:

1) rice field is selected:

Select field base firm, have abundant water resources, irrigation and drainage are convenient, and the rice field of preserve moisture and fertility is as crawl;

2) rice field process:

More than 50 centimetres, heightening and consolidation field base, the fish hole of 20 square metres is offered in every mu of field, and fish ditch is " well " font or " ten " font, Yu Gou and Yu Keng is connected, fish furrow width 30-50 centimetre, Yu Gou, Yu Keng are deep to the hard end, rice field, and fish hole inwall surrounding plank or slabstone are built into barricade;

3) fingerling stocking:

Fingerling 500 tail is thrown in summer and winter in every mu of rice field, carp 480 tail, grass carp 20 tail; Put in a suitable place to breed in process, water temperature difference is less than or equal to 4 DEG C, first with the physiological saline soaking disinfection fingerling 30 minutes that mass percentage is 3% before putting in a suitable place to breed;

4) raise and management:

The farmyard manure more than 1000 kilograms become thoroughly decomposed is used in every mu of field, particulate material day feeding volume be the 3-5% of fish body gross weight; Water in field remains on 5-10 centimetre.

Beneficial effect of the present invention is: the cultural method that a kind of rice field ecology provided by the invention is breeded fish, and the fish bulk-growth speed that can effectively solve in rice field fish culture process is slow, the problem yielded poorly, and meanwhile, can ensure that paddyfield water cleans, be beneficial to cycle development.

Embodiment

embodiment 1:

one, the primary condition of fish-culture paddy field:

Field base is firm, has abundant water resources, and irrigation and drainage are convenient, the rice field of preserve moisture and fertility.

two, irrigation facility:

More than 50 centimetres, heightening and consolidation field base, the fish hole of 20 square meter is offered in every mu of field, and fish ditch is " well " or " ten " font, and Yu Gou and Yu Keng is connected.Fish furrow width 30-50 centimetres, ditch, hole are deep to the hard end, rice field, to increase the water body of fish movement.Fish hole inwall surrounding plank or slabstone are built into barricade, and the mud avalanche of anti-field is collapsed.

three, fingerling stocking:

Every mu of rice field about summer and winter throwing in fingerling 500 tail, based on carp, about collocation grass carp 20 tail.

Fingerling stocking points for attention: 1, action is brisk, avoid hindering fish; 2, water temperature difference is no more than 4 DEG C; 3, the raw saline sook sterilization fingerling minute first with 3% before putting in a suitable place to breed, in case fish disease.

four, raise and manage:

1, based on farmyard manure, some pellets of suitably throwing something and feeding.The farmyard manure (dung polluted water and marsh gas water etc.) more than 1000 kilograms become thoroughly decomposed is used in every mu of field.Particulate material day, feeding volume was 3-5% of fish body gross weight.According to the upgrowth situation of water quality, weather, fish, grasp fertilising and the throwing amount of raising flexibly.

2, normal water level is kept.Summer, kind rice will according to the upgrowth situation of paddy rice, and when not affecting rice tillering, water in field remains on 5-10 centimetres, and winter then keeps the maximum depth of water according to the height of Tian Ji as far as possible.

3, Scientific Usage of Drugs.When paddy rice desinsection needs to use agricultural chemicals, low toxicity, highly effective pesticide be used, prohibit the use as highly toxic pesticide such as first ammonium phosphorus.

4, strengthen making an inspection tour, take precautions against drought, prevent waterlogging, anti-to escape, diseases prevention.

Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
