The present invention mainly comprises following technical measures.
1, irrigation facility measure.Engineering measure mainly comprises rice field fish culture engineering and the reed pond engineering of breeding fish.In the developing zone of defining, the saline-alkali wasteland of reed pond periphery all is developed to the step rice field along contour, beat motor-pumped well simultaneously as the water source, excavate and improve various canal for water conveyance, all drainings all enter the reed pond.Monolithic field area 0.1～0.3hm
2, all carry out single single the filling, prevent to cause secondary salinization.According to the area size, the fish ditch of excavation " field ", " day ", " order " font respectively wherein, increases in the central authorities of " day ", " order " font fish ditch again and to dig one and go here and there heart ditch in each field piece.Fish ditch specification is: wide 70～80cm suitable for reading, following bottom width 30～40cm, dark 40～50cm.This fish ditch can adapt to the physicochemical property of carbonate type saline-alkali soil preferably, and the more traditional fish ditch of the effect of breeding fish obviously strengthens.In addition, respectively dig the fish hole of a long 2m, wide 1.5m, dark 1.0～1.2m respectively at fish ditch intersection point place, water inlet and discharge outlet place.Each field piece open fire face of breeding fish can account for 10%～15% of Honda area, obviously increases than 5%～8% of traditional approach, helps paddy rice dense planting and medication prevention and elimination of disease and pests.
The reed pond engineering of breeding fish comprises: excavate the circular groove of wide 8～10m, dark 1.0～1.2m around in the reed pond, the soil that digs out is built a dam in the periphery.Reserve the wide wave eliminating band of 5m between dam foundation inboard and the circular groove outer rim, prevent that stormy waves from damaging dykes and dams.Wide by 1.5～2.0, dark 1.0 open fire ditch is excavated along the relative smaller part of a reed density in inside, reed pond, and communicates with circular groove, and its layout is " well " font substantially, so that improve the ventilation transmittancy of reed pond, improves the ecotope of reed pond.The reed root (bud) that digs out is transplanted to other places with the form of knoll, to increase reed density.The inlet channel of reed pond communicates with the drainage ditch in rice field, can make the water source, reed pond like this except that whole admittance paddy field drainages, also can directly utilize rice field well moisturizing, guarantees the reed pond water of breeding fish.The reed pond fish culture waste water enters a special-purpose retaining grass pool, obtains the purified treatment of water plants there, and next year is put the temporarily foster water source of fish the beginning of spring as the reed pond.Thereby make whole production system realize non-pollution discharge.
2, cultured fishes and stocking method.The kind of rice field fish culture is carp, crucian and grass carp.Kind is cultured except that above-mentioned 3 kinds of fishes in the reed pond, also increases and puts silver carp, bighead and megalobrama amblycephala, arrange in pairs or groups simultaneously a small amount of catfish and snakehead.Definite stocking rates such as fingerling specification, the rate of recapture, plan yield are all pressed in reed pond and rice field, and catch specification adjustment according to the actual production in every year with rising.Generally in rice field fish culture, the carp stocking rate is 30～75kg/hm
2, specification 70～90g/ tail; Crucian stocking rate 10～40kg/hm
2, specification 25～40g/ tail; Grass carp stocking rate 30～90kg/hm
2, specification 110～130g/ tail.In breeding fish in the reed pond, the stocking rate of above-mentioned 3 kinds of fish is respectively 220～300kg/hm
2, 5～30kg/hm
2With 30～60kg/hm
2, specification is respectively 70～75g/ tail, 20～30g/ tail and 90～150g/ tail.In addition, the silver carp stocking rate is 20～40kg/hm
2, about specification 70g/ tail; The bighead stocking rate is 15～60kg/hm
2, about specification 75g/ tail; Megalobrama amblycephala 10～20kg/hm
2, specification 30～40g/ tail.
3, water quantity management.Western part, the Northeast, fish, rice symbiosis are synchronous to the demand of the water yield, as long as guarantee fish ditch full water, brown water quality (this phenomenon is the sign water colour of the salification accumulation of salt in the surface soil) do not occur and get final product.The water quantity management method of breeding fish in the reed pond is mainly adhered to the principle that fish, reed are taken into account, and takes three fillings, three row's measures of " full Qiu Luogan of shallow summer in spring ", implements the reed pond water quantity regulation.Concrete grammar is: the 5～10cm that pours water the first tenday period of a month in May, and the early June draining is to the face depth of water 3cm of the pool; 20～the 30cm that pours water mid-June, the late July draining is to the face depth of water 5cm of the pool; 30～the 40cm that pours water at the beginning of 8 months begins draining mid-September, the left and right trunk pool at the beginning of 10 months.
4, the rational application of fertilizer.For improving saline land water, autochthonal attitude environment, no matter measures of fertilizer all must be taked in rice field or reed pond.The fertilizing method in rice field is: as base manure, execute farmyard manure 12～18t/hm
2, urea 450～600kg/hm
2, superphosphate 120～150kg/hm
2, zinc sulphate 15～30kg/hm
2As topdressing, execute urea 150～180kg/hm
2, potassium sulphate 120～150kg/hm
2In 6～August, every 10～15 days Xiang Yugou, fish underground water bodies fertilizer liquid dung of splashing a time, concentration is 50%～60%, consumption 50～100g/ (m
3Water body).Executed in every month 2～3 times.The reed pond fertilizing method is: put fish and executed farmyard manure 4500～7500kg/hm in preceding 5～7 days
2, executed once every 10～15 days for 6～August, quantity 1200～1500kg/hm
2, executed 2～3 times in every month.When the reed pond water temperature reaches more than 20 ℃, enriched one time urea 2～5g/ (m every 7～10 days
3Water body), superphosphate 4～8g/ (m
3Water body), executed in every month 3～4 times.For satisfying the reed growth needs, also should replenish the content of water body potassium, its method is to enrich potassium sulphate 10～15g/ (m
3Water body).In total fertilizing amount in above-mentioned 1 vegetative period, the quantity of basal dressing accounts for 60%～70%, and the consumption that topdresses is controlled at about 30%～40%.Especially chemical fertilizer, the consumption that topdresses is too much, can produce harmful effect to fish.
5, improvement reed pond ecotope.Before thawing the annual beginning of spring, will gather in plants such as the remaining reed in back, wormwood winter and set fire and burn, shallow again turning over or the heavy duty harrow (degree of depth 5～10cm) of breaking ground once after thawing.After handling like this, can make ground, reed pond in spring 5～10cm soil temperature improve 3～7 ℃, water temperature increases by 1.7～3.2 ℃, simultaneously, can increase in water layer and the soil reed requisite potassium element content that grows again, and improve the water body content of organic matter, promote the breeding of fish natural baits such as plankton and outstanding bacterium.In addition, during breeding fish,, in time open fire ditch both sides 2m is far all sliced off with interior reed grass, help printing opacity oxygenation when reed and wormwood grow the water surface 50cm when above.Survey factually, the water body dissolved oxygen content after the mowing remains on more than 6～10mg/L than increasing by 10%～20% under the reset condition.
6, supplement feed.Under the nature, by the fish crop that natural bait provides, the rice field is generally at 120～180kg/hm
2, the reed pond is at 900～1200kg/hm
2So, want further to improve fish crop, must replenish the artificial feed of throwing something and feeding in addition.Its method is: during fish growth, according to weather, water temperature situation and factors such as the fish movement and the situation of ingesting, reed pond every day is by 45～150kg/hm
2Quantity, the fixed point pellet (or mixed feed) of throwing something and feeding, the quantity of throwing something and feeding in a vegetative period is at 2500～3200kg/hm
2Fish was put after 5～7 days in the rice field, fixed a point to throw something and feed once in fish ditch or fish effluent body every 1～2 day; Paddy rice Feng Hanghou, 2～3 o'clock of every afternoon throws something and feeds once.The quantity of throwing something and feeding in a vegetative period is at 1000～1500kg/hm
2About.
7, disease control.All fingerlings all embathe sterilization 5～7 minutes with 5% saline solution before putting in a suitable place to breed.Put preceding 5～7 days of fish with 1.5g/ (m
3Water body) bleaching powder is to the water body disinfection in the open fire ditch of reed pond.In 6～August, to the zone that reed pond water body Mesichthyes activity is comparatively the concentrated bleaching powder of splashing a time, splash in fish ditch or fish effluent body in the rice field about every first quarter moon, and concentration is 1.5g/ (m
3Water body).To the insect of paddy field and reed,, make it to fall into water body and got food by fish manually to drive.The rice field adopts thin spray-on process to use a small amount of agricultural chemicals.Adopt said method, more serious fish disease and rice pest generally all can not take place in rice field and reed pond.
8, fishing in good time.Because the rice field begins draining in autumn dry field in early September, so should catch out the fish in field this moment, be put in the fence in the open fire ditch of reed pond, the artificial throwing raised, and continues to support by the end of September, catches out simultaneously with the reed pond fish, can increase fish crop 5%～10% like this.Mid-September, the reed pond begins draining, but drainage speed is unsuitable too fast, and is stranded in order to avoid the fish in the reed, thick grass have little time to swim out of.Water level is advisable about 3cm to descend every day, expects by the end of September or does at the beginning of 10 months the pool and get final product.
9, reed pond mud returns the field and improves the soil.Because heavy dressing and alluvial make the annual 10～15cm of increasing of reed pond bed mud, wherein are rich in nutritive elements such as organic matter and nitrogen, phosphorus, potassium.For making full use of fertile pond sludge resource, before thawing the annual beginning of spring, reed pond pond sludge is removed 5～10cm apply the rice field, play the effect of improvement saline-alkali soil and culture fertility.
Fish-reed-rice comprehensive exploitation promptly is the model of effective utilization at northeast song-Nen plain carbonate type saline-alkali wetland.It is to be development object with low-lying nmoncontributing area reed wetland, is the center with the reed pond, and periphery is developed to the rice field, carries out the reed pond and breeds fish and rice field fish culture, and enter the reed pond by paddy field water either and realize comprehensive utilization of water resources.Simultaneously, this system combines 2 kinds of ecological fishery patterns by comprehensive utilization of water resources, not only makes reed pond 1.1～1.3 ten thousand m that can economize on water every year that breed fish
3/ hm
2, reduce 260～300 yuan/hm of cost
2, and the integrated assembling of biological control measure of 2 kinds of breed, plantation such as breed fish of system engineering measure and rice field fish culture, reed pond, form the supporting technology system, make 3 kinds of agricultural product such as fish, reed, paddy rice all obtain good harvest, its economy, ecology and obvious social benefit.Practice shows that this pattern is comparatively reasonable, meets the natural environment characteristics of low-lying saline-alkali wetland, to arid, semiarid zone development water-saving agriculture (fishery), especially to the comprehensive development and utilization of salinized reed wetland, provides a new approach.
Practice shows that fish-reed-rice production system is set up in the exploitation saline land, not only can increase economic products such as fish, paddy rice and reed, increases economic efficiency, but also has tangible ecological benefits.As in the ecosystem is breeded fish in the reed pond, reed can absorb all kinds of salt and alkali components and enrichment noxious material, and suspension in the adsorbed water, and the paddy field water either that enters the reed pond is purified, create a nontoxic aquatic ecological environment that lacks disease to cultured fishes, the promotion fish perch and grow.Simultaneously, weeds and insect that the desirable food of fish is harmful to reed, fish faeces also can increase the source of manure, and its feeding activity again can the ploughing and weeding water body, and chesson promotes the rhizomatous growth and breeding of reed, helps improving quality and the output of reed.In the rice field fish culture ecosystem because the effects of ingesting of fish, make rice field harmful insect, rice pathogenesis rate and weeds output all more not fish-culture paddy field obviously descend, chemical fertilizer and pesticide dosage also significantly reduce.In addition, because the absorbing enriched of plants such as rice straw, reed and the effect of draining drip washing, and the comprehensive utilization of pond sludge and fertilizer, alkali falls in the soil that makes fish-reed-rice pattern desalination to a certain extent, and soil physical and chemical property is tending towards improveing.According to another actual measurement, in the season of growth in 5～September, the wilderness is high by 14%～22% on every side for the ground layer relative air humidity in the modular system, thereby has the effect of regulating and improving microclimate.
