Preferably, the consumption of described quicklime is every mu of rice field 75-100kg.Calcification water is splashed in Yu Yudang, fish ditch and field, and to carry out disinfection, at the bottom of instrument Jiang Dang, ditch and the fields such as inferior daily rake, raking, makes lime white fully mix with mud once, reaches comprehensive sterilisation purpose.
Preferably, described rice varieties is reed rice.The plant type of rice of reed rice varieties is tall and big, and plant is up to 160-180cm, and likeness in form " reed ", is commonly called as reed rice.The thick stalk of reed rice stem is strong, and leaf sheath is thick and heavy, and clasping power is strong, and clasping face is large, and lodging resistance is extremely strong; Well developed root system, can grow on each joint while growth and form flourishing water root in water, and suction is fertile and resistance to fertility is strong, has excellent water body purification ability; Blade is long, thick, very, leaf color depth, annesl is smooth and easy, ripe mutually splendid, resistant to diseases and insects is strong, and this paddy rice can grow at deep water, generally, in the depth of water growth of 0.6-1m, with respect to the 10-20cm water level growth of common rice, deep water growth is not easy to the advantage that damaged by vermin occurs in addition.
Preferably, the consumption of described livestock and poultry muck is every mu of rice field 180-220kg.Livestock and poultry muck need to first ferment, and fermentation refers to stacks a period of time by livestock and poultry muck, to prevent that it from producing heat while being applied in rice field, and the rice root in rice field is caused damage.Using taking rich water as main of livestock and poultry muck, be specially: use and front animal wastes are first fermented, stack a period of time, then via hole diameter is that sieve water that length and width are 0.5-1.0cm is rushed in row and filtered, discard the bulk impurity of staying above sieve, the ight soil of water punching is for rich water.
Empirical tests, described loach seedling 1.5-2 ten thousand tails are put in every mu of rice field in a suitable place to breed, and every cabrage amount is 3-5g.Well-grown is supported in loach and rice field altogether.Loach seedling can directly be put rice field in a suitable place to breed, also loach kind first can be raised in cultivation ditch, after waiting rice transplanting to turn green, floods, and puts in a suitable place to breed to rice field.Be specially: after rice field irrigation facility finishes, put in a suitable place to breed first 2 weeks, splash in Yu Yudang, fish ditch and field with 75-100kg quicklime water for every mu, to carry out disinfection, at the bottom of instrument Jiang Dang, ditch and the fields such as inferior daily rake, raking, makes lime white fully mix with mud once; Put and apply the livestock and poultry muck fermenting kind of the last week and carry out rich water, mu consumption 200kg, to cultivate natural bait in water; To fish for loach kind from natural water area, and require physique healthy and strong anosis without wound, the age is in 2 ages, female body weight 15-25g, and 12 grams of male body weight are above to be put into cultivation ditch in early April by loach kind and raises, and improves water level in paddy field again and put loach and enter field after rice shoot is turned green.
Preferably, before putting in a suitable place to breed, to described loach seedling sterilization, any in described sterilization in the following ways:
(a) salt solution of 2%-3% soaks 8-12 minute;
(b) 5%-7% saline solution embathes loach body 10-15 second;
(c) 0.1mg/kg-0.2mg/kg liquor potassic permanganate embathes loach body 10-15 second.
Because loach is suitable for paddy field cultivation, in breeding process, generally do not have disease to occur, but or need to carry out certain preventive measure.First to adhere to healthy aquaculture, by code operation, take precautions against in possible trouble.Secondly, carry out prevention work: the one,, the sterilization of loach seed, loach seed is put in a suitable place to breed to rice field it is carried out disinfection, and sterilization can adopt 2% salt solution immersion 10-12 minute, also can be for adopting 3% salt solution to soak 8-10 minute; Sterilization can adopt 5%, 6% saline solution to embathe respectively loach body 12-15 second; Also can adopt 7% saline solution to embathe respectively loach body 10-12 second; Sterilization can adopt 0.1mg/kg liquor potassic permanganate to embathe loach body 12-15 second; Also can adopt 0.2mg/kg liquor potassic permanganate to embathe loach body 10-12 second.The 2nd,, regularly sterilization, every 10-15 days executes quicklime by every mu of 15-20kgization water full pool spilling head, and monthly 1-2 regulating reservoir water pH value be to alkalescence, improves pond microorganism structure with biologic product, improves water quality.
The disease that the Common Diseases of loach has the parasites such as Trichodina, tongue cup worm, Gyrodactylus to cause.Bacterium infects the red skin disease causing, rotten fin disease, tail, and is infected saprolegniasis causing etc. by water mold.Parasite main harm loach seed, can adopt 0.6mg/kg copper-bath or prevent and treat Trichodina and tongue cup worm with the mixture (5: 2) of ferrous sulfate composition; Kill Gyrodactylus with the trichlorphon of 0.3mg/kg.Red skin, rotten fin, rotten tail normally because fish for transportation in abrade the factors such as fish body and water quality deterioration and bring out.The bleaching powder full pool spilling head that the chlorine dioxide that employing concentration is 0.3mg/kg or concentration are 0.8-1.0mg/kg, in conjunction with the terramycin soaking disinfection with 10mg/kg, can prevent and treat these bacterial diseases.
Loach is put in a suitable place to breed to rice field, keep the water in rice field to be dark brown, and transparency is 25-30cm.Generally fertilising once, applies person poultry muck at every turn weekly, and consumption is by every mu of 150-200kg.In the time that being greater than 30cm, fine, water transparency can suitably increase fertilizing amount; When water quality overfertilization, should reduce or stop fertilising, and inject new water.
Loach is ominivore-fish, under Artificial feeding conditions, cultivates plankton bait by fertilising, the residual bait at the bottom of sedimentation basin, the foodstuff that excrement slag also can be done it; The commercial feed of also can throwing something and feeding, as groundnut cake, rice bran, wheat bran, soya-bean cake, dried silkworm chrysalis meal, spiral shell, earthworm, water silk earthworm, the flesh of fish, domestic birds and animals internal organ etc.Loach individuality is little, lightweight, gluttonous, easily causes indigestion while having enough, affects eupnea and causes swollen deadly, therefore, in breeding process, continuous in order to ensure plankton, must impose fertilizer in time, on a small quantity, equably, as animal wastes.Particularly, every fertilising in 10-15 days 1 time, each every mu of fertilising 150kg.According to the concrete condition of water colour, execute urea or the 2.5kg ammonium hydrogencarbonate of 1.5kg left and right for each every mu, to keep water body to be yellow green in addition.
Preferably, each daily ration, feeding quantity is as the criterion to eat up in 1-2 hour.Particularly:
Loach is in the growth busy season, as the 7-8 month, taking animal bait: vegetal bait is as the weight ratio of 1:1, day bait throwing in 2 times, and each daily ration, feeding quantity is the 8%-12% of loach gross weight; Loach is in growth dull season, as the 9-10 month, and the vegetable feed of throwing something and feeding, day bait throwing in 2 times, each feeding volume is the 2-4% of loach gross weight; The 3-6 month and the 11-2 month, the vegetable feed of throwing something and feeding, day bait throwing in 2 times, each feeding volume is the 1.5%-2.5% of loach gross weight; Above Feeding time is morning and afternoon respectively once.In general, four Maies of loach put in a suitable place to breed to rice field, and loach is put the initial stage in a suitable place to breed mainly taking the natural bait in water as food; Gather in the crops October.According to market demand, loach is being arrested around the Spring Festival sometimes, loach sky is cold basic has not just eaten food, also without bait throwing in material.Feed of animal origin comprises: dried silkworm chrysalis meal, spiral shell, earthworm, water silk earthworm, the flesh of fish, domestic birds and animals internal organ, fly maggot, spiral shell, freshwater mussel, slaughter house offcuts etc., vegetable feed comprises: groundnut cake, rice bran, wheat bran, soya-bean cake, bean dregs, rapeseed cake etc.
Whether note day and night patrolling field, will adhere to every day early, patrol field evening, observe loach and ingest normally, check that whether ridge is leaky, particularly the rainy day, prevent that natural enemy from invading as water snake, duck etc. if noting carefully checking leak.Note checking into draining barricade have damage to repair in time.In the time that water temperature exceedes 30 DEG C, often change clear water, and increase the degree of depth of water, be strictly on guard against by the water of pesticide pollution and enter field.As loach often swims over to the water surface " ventilation " or moves about at the water surface, show to inject new water, stop fertilising.
Loach is temperate water fishes, is khaki in rice field, and its growth water temperature is 15-34 DEG C, and the most suitable growth water temperature is 24-30 DEG C.In the time that water temperature drops to below 5-6 DEG C or higher than 35-36 DEG C, it just slips into 10-30 centimetre of mud layer in mud and carries out dormancy, so the rice field of breeding loach should be selected cautiously, generally should select to have abundant water resources and stable, water quality is pure and fresh and pollution-free, note that draining facilitates, water retention property is good and have a good transport service, field that water conservancy projects is good.Preferably, described rice field be positioned at have abundant water resources, the convenient and good position of water retention property of irrigation and drainage.For the ease of management breeding loach, preferably, described rice field is 2-10 mu.Support after shrimp in rice field, and the insect pest of paddy rice obviously alleviates, and especially can use light trap to lure insect.
