泥鳅苗一般在春分先后投放,刚买的泥鳅苗身体薄弱虚弱,.doc

，The long sand county blessing faces a town thou the Peng Wei of village in Hua Mountain, once was a pig-raising the big door , under persuasion and supported that government, participated in a pig farming, chose farming loach.Only one year covered the loach farming of 1.33 hectares to have scale ever and rather.He buys from Hubei by the price of each 25 dollars into grow Qiu and studied to hatch from eggs technique means for 3 months.The loach egg hatches from eggs to water temperature, water soon, aquatic contain amount of oxygen to all have a request, the loach hatches from eggs an essential tube of temperature to teach about 22 , besides not the ability is a flowing water.For this, the Peng Wei used to hide a sun net to build shed above in the pond son and also packed for the pond son ascend water soon the tube teach valve, uncertain infusion oxygen.Hatch from eggs to feed inside the pond for 7 days in the wreath way after hatching from eggs into such as hair silk thick thin small loaches, put again to put to keep a farming in pond in the open.The farming loach is all very high to the application of fluid matter, hatch from eggs water of pond and farming pond from the deep well in pull out.The Peng Wei still trampled upon to only match a germ to put into water to have no machine germ by going into action and then pollute water body.Feeding of the loach also has to pay attention to, the loach seedling is very small, can feed bean milk, and the big loach feeds earthworm, fly Ju and wheat Fu etc.For increasing efficiency, Peng Wei still just set in Shui-li kept field snail.Field snail and loach dont influence with each other, each 667 square meter farmlandses can create a 500 kgs1500 kilogram field snails, this is also a not small expenditure.The loach farmland can also grow for a quarter, paddy rice, next move he will grope for to this aspect.Each 667 square meter farmlandses can produce 1 ton1.5 ton loaches, the year always makes to measure to 20 tons30 tons, act according to every 1000 grams of 36 dollarsesprice aggregate in the market of 50 dollars, a year of profits is particularly considerable.Keep loach since hygiene environmental protection, efficiency and then Gao.Under his proposal, there are already 8 farmers in district also along with the farming loach, the Peng Wei leads long a head to establish the loach farming cooperation agency.Currently, our country the artificial loach creation quantity year by year descend, while the market is necessary again year by year rally, the market blue print of farming loach is optimistic about.The loach seedling generally successively throws in in vernal equinox, just- bought loach seedling body weak infirmity, slightly dont expect while going into pond, have or result in a little bit greatly off the trail, eventhe ensign opens and wins.Hence, when the loach seedling goes into pond, dont necessarily need to be careful the following important point:1, the airtight net pull a pond pure harmThe loach seedling wants to pull a few empty ponds with the airtight eye net for a day before going into pond.The surplus that on the other hand makes to accumulate in the pond bottom pure pond medicine increases deliquescence, in order to prevent the poison harms Qiu seedling;Expel an enemy on the other hand and further, if creating the enemy can be used 0.5 grams/sign enemys 100 insect whole pondses of square rice density to spill a development to kill to put out.2, carry out pure pond scholastic attainmentDont necessarily need to search the medicine poison of pure pond whether dint is concealed, have no before the loach seedling goes into pond, and whether aqueous fatty degree agrees with .Take half bucket water first, because of occasionally surface layer water poison dint have been already disappeared, but the poisonous dint of the first floor is still very strong, put the loach seedling into water to inspect for 810 hours, see whether can go into pond with destining loach seedling as usual.Secondly can anticipate living creature environment and decide arbitrarily an aqueous fatty degree according to the water color, clarity and bait, if once discovering pond water is fatty, can add and note clear water and adjust;The fatty degree of pond water isnt enough, should immediately repair large numbers of turn is fatty or once fermented of muck or increase to throw artificial bait to anticipate.3, work well slow seedling Cuo to placeApply for pond water temperature when the loach seedling goes into pond degree dont can be lower than to carry fish water temperature 3 .If the water temperature once differed greatly, should first and gradually adjust a difference in temperature, the loach seedling adapts to behind again go into pond.The loach seedling transported with the plastics bag, at go into should stop talking plastics bag first before the pond the sensitive put go into open a beginning to settle down inside the good water tank, after 1020 minutes again loach seedling connect water quickly pour into a box together and lend this to adjust to manage water temperature bad and loach seedling to bag inside air pressure change of conformance, compare to slow seedling.On the supposition that create loach seedling to present to lie on the back shape while opening bag, this is two erosion carbon poisoned situation, needs slow seedling through the process, putting into clear water a time can immediately recover.Assumption directly poured into pond from the bag the loach seedling, even if while putting to keep the naked eye observed to keep as usual, descend pond after will also take place to be born, then conveyance after be born to avoid a life time.With the slow seedling treatment punishment be not to necessarily do become a little demand path and pace.Moreover, loach seedlings going into should develop medicine disinfection before the pond.Can use 1% little Sus to draw water to immerse to wash for 2030 minutes.4, keep a satisfied food pondThe Qiu seedling Huan keeps of livinging and creating actual confirmation, Qiu seedling into feed 12 familiar egg yolks or animal feed leaven before the pond, if can gain insect hurl to feed more ambition, it become live rate or grow velocity all compare dont feed of have obvious headway.The Qiu seedling first feeds bait with the net box after carrying, again afresh lead number go into pond.The Qiu seedling of the advantage head while taking seedling in the net box the similar and common physical endowment is stronger, more big separately, the Qiu seedling of the next head the physical endowment is worse, smaller separately, such as can is different the individual size, the physical endowment strong or weak have in addition Qiu seedling background merger.5, deep water stick noodles to put seedlingAccording to the performance, from 30 Li rices eminence pour into water, Qiu seedlings injures 5%10%;When being 60 Li rices apart from the surface is high, the fish fry harm rate can reach to 20%30%.Therefore, Qiu seedling next pond want to make a choice deep water place, tightly stick a surface to gradually put seedling, if create Qiu seedling intensive conglobation, use water to order lightly Qing Xie and make it spread out to visit into pond.Touch to blow the color of the sky, at up the situation deep water place go into pond in case the Qiu seedling is blown a pond ascent by the breeze or press pond bottom but formation dead and injured.6,
