Abstract

The invention relates to a cultivating technique of cross bred lobster in rice field and pond. The technique is the producing manner which utilizes the shallow water environment in the rice field and is supplemented by artificial measures to plant the rice and cultivate the lobster to increase the profit of the unit rice field area. Since the freshwater cross-bred lobster has low requirements on water and the cultivating place, and fish culture in paddy field is a tradition in a plurality of areas in China, and the economic profit of the unit rice field area can be effectively increased by popularizing the culture of the freshwater cross-bred lobster in the rice field when the profit of fish culture is dropped. The culture of the freshwater cross-bred lobster in the rice field can facilitate weeding and pest eliminating in rice field and save fertilizer and pesticide; and the rice yield of the rice field raising the lobster can be increased by 5percent to 15percent generally. In some areas, in particular the areas of waterlogged lowland, winter macerated fallowland and cold water paddy field, where only single cropping is allowed, the mode of the rice planting and the freshwater cross-bred lobster cultivation in turn is adopted and the economic profit is remarkable.

Description

Rice field and pond hybridization lobster cultivation technique

Technical field:

The invention belongs to the cultural technique field, be specifically related to a kind of rice field and pond hybridization lobster cultivation technique.

Background technology:

As everyone knows, lobster is the food of liking during people live, and existing lobster breed all is that growth is cultured among rivers,lakes and seas, be difficult to improve its output and quality, satisfy the demand that people eat, people wish to find a kind of technology that can utilize rice field and pond extensively to culture lobster, improve the economic benefit of vast farmers.

Summary of the invention:

The objective of the invention is provides a kind of pond, rice field hybridization lobster cultivation technique that utilizes according to above-mentioned weak point, because hybridization lobster is to water quality and feed, site condition is less demanding, there is paddy field aquaculture in many in addition areas, make this utilize the rice field not only to plant rice but also support shrimp, to improve rice field unit are economic benefit, rice field feed fresh water hybridization lobster can be paddy field weeding, remove insect pest, the Shaoshi chemical fertilizer, few pesticide, the rice field of supporting shrimp can increase output 5-15% for every mu, particularly those can only plant the low land reclaimed from a lake in a season, the winter soaked field, the general field of soaking, the pattern economic benefit of taking semilate rice and fresh water hybridization lobster to do is very considerable.

Rice field of the present invention and pond hybridization lobster cultivation technique are to realize like this.

The rice field is built: should select water quality good, water yield abundance does not have pollution source on every side, and water retention capacity is stronger, and irrigation and drainage are convenient, the rice field that is not subjected to flood inundation on tracks.The rice field ridge must be widened heightening and consolidation, set up the cloudy canopy of sugarcane, advancing draining sets up and puts filtration, the anti-net of escaping, around inboard, excavate annular shrimp ditch, the furrow width 0.8-1.8 rice of supporting along field, rice field stalk, dark 1m, field piece area is bigger also will excavate " ten " font, " well " font or " day " font field ditch, field furrow width 0.5-1.2 rice between Tanaka, dark 0.5-0.8 rice, annular shrimp ditch and field ditch area account for about rice field area 5-12%.

Cleaning sterilization: put shrimp preceding 10-20 days, and must clear up annular ditch and field ditch, remove surface dust, the furrow bank that correction is collapsed, every mu of rice field annular shrimp ditch quicklime 30-60 kilogram, or select other drug for use, wild fishes class, harmful animal thing and pathogenic bacteria are killed in thoroughly ditch cleaning sterilization.

Dispensing base manure: before putting shrimp 8-12 days, inject 30-60 centimetre in water in the rice field, food organisms are cultivated in fertilising then, execute the fertile 500-1000 kilogram of organic farming, once use sufficient for every mu.

The biology of planting: heavy water-based water plants such as the wheel blade of in annular shrimp ditch, planting, black algae, hornwort, pondweed, at limes marginis plantation water spinach, culture cucurbit at the water surface, control the pasture and water area, general pasture and water account for the 30-60% of annular shrimp ditch area, sporadicly to be distributed as, help the unblocked plug of current in the shrimp ditch.

Filter and anti-escaping: advance, discharge outlet will be installed the bamboo paper tinsel, wire netting and net sheet etc. are anti-ly escaped, filtration facility, is strictly on guard against that harmful organisms enters or freshwater lobster is escaped with current.

Juvenile prawn is put in a suitable place to breed: will try the water when putting in a suitable place to breed, just can throw in juvenile prawn, stocking method after the safety of trying the water: the one, the close shrimp of fresh water hybridization lobster is directly put in a suitable place to breed in the rice field, allow it breed voluntarily, put the above freshwater lobster 15-25 kilogram of 40 grammes per square metres in a suitable place to breed for every mu, and adopt the no-tillage system rice cultivation; The 2nd, after paddy rice was transplanted seedlings, throwing in people shrimp specification was 2-5 centimetre, threw in the 8000-12000 tail for every mu, will note the quality of juvenile prawn when putting in a suitable place to breed, by specification single step of releasing foot.

Field management: freshwater lobster is raised in the rice field, except that epipodium base fertilizer, the feed of generally not throwing something and feeding, the cow dung of in ditch, throwing some pasture and water drought grass and becoming thoroughly decomposed, growth can be thrown something and fed some feed of animal origin as hammering the broken spiral shell freshwater mussel meat and the offcuts of slaughterhouse etc. into shape during the busy season, adheres to patrolling the field every day sooner or later, observes water colour variation and shrimp activity in the ditch, food, growing state.

Embodiment:

Paddy field aquaculture hybridization lobster of the present invention is also noted that following steps:

The rice field dry field: the paddy dry field is suitable light roasting, can not fully water in field be drained, and water level is reduced to the field and shows out and get final product, and the time is unsuitable long, and whether the observation lobster has abnormal response, then water filling immediately when responding.

The rice field fertilising: it should serve as the main lasting long-acting purpose of fertility that reaches to execute the organic agricultural fertilizer that becomes thoroughly decomposed that rice field base manure will use sufficient, and executes per 10 kilograms/mu of biological compound fertilizer, forbids to use chemical fertilizer, as ammoniacal liquor and carbonic hydroammonium etc.Lobster is all very sensitive to agricultural chemicals, can suitably select the public nuisance-free agricultural chemicals of high-efficiency low-toxicity when the paddy rice pesticide grown needs for use, sprays rice leaf and does not spray in the water as far as possible.

Rice field kind grass: transplant pasture and water at annular ditch, field ditch, raise ditch pasture and water coverage rate and be advisable with 40-50% as water plants such as water caltrop, hydrilla verticillata, house fish algae, pondweed, water calabash, rice field annular, and with fragmentary, be separated into.

The anti-disease prevention of escaping in rice field: check whether the import and export screen cloth is firm every day, prevent to leak and escape shrimp, lobster is supported in the rice field, its harmful animal is more, as the frog, water snake, loach, swamp eel, predacious fish, before putting in a suitable place to breed in water mouse and some birds thoroughly removing be also noted that harmful organisms in the removing field at ordinary times, having ready conditions can be provided with some on the limit, field and adopt bar or scarecrow and threaten and drive aquatic bird.
