Abstract

The invention relates to the field of breeding of aquatic products, in particular to an alpine thin-shell field snail breeding method. The alpine thin-shell field snail breeding method includes steps of setting empty rows in rice field at the altitude of 800-1200 meters, reproducing and breeding field snails in the empty rows, and harvesting in the following year. Thus, usable area of cultivated land is reduced, cultivation area is reasonably utilized and higher yield is obtained.

Description

The cultural method of a kind of high mountain shell river snail
Technical field
The present invention relates to aquaculture field, be specifically related to the cultural method of a kind of high mountain shell river snail.
Background technology
He Hu township, Qingyuan County, Zhejiang Province is seated in high and steep mountains, Qingyuan County, high-land, and temperature is low.Full township height above sea level is more than 1000 meters.A kind of wild river snail that growing in local paddy field, locals is called high mountain shell river snail it, and its kind need to confirm.Compared with common river snail, high mountain shell river snail chitin is very thin, when edible with tooth gently once stinging energy broken shell, its meat is finer and smoother, more delicious, in every gram of dry spiral shell, contain amino acid 587.08mg, essential amino acid 280.08mg, in every 100 grams of fresh samples, the content of calcium and zinc reaches respectively 1762 and 5.017mg, more high than commercially available common river snail (Cipangopaludina chinensis).In every gram of shell river snail, delicate flavour amino acid and sweet taste amino acid are respectively than the high 12mg of common river snail and 3.7mg, and Here it is closes lake high mountain shell river snail than the reason of common river snail deliciousness.On the ground such as Wenzhou, Lishui, enjoy higher popularity and credit worthiness, market welcome degree far away higher than common river snail, price also exceeds much than common river snail, ceiling price reach 50 yuan/more than kg.
Although this river snail has multiple advantage,, exist at present high mountain shell river snail fish brood amount low, the shortcoming such as growth rate is slower, yields poorly, and accommodation is narrow, has seriously restricted the income of local farmers.In addition, because large quantities of labours outwards shift, lay idle seriously in field, and the output of uncultivated withered field river snail is few.How to develop a kind of cultural method of this river snail of being applicable to, income that not only can local people, and affect a kind of development of high-quality aquatic products.
Summary of the invention
To the object of the invention is in order addressing the above problem, the cultural method of a kind of high mountain shell river snail to be provided.
In order to reach foregoing invention object, the present invention by the following technical solutions:
A cultural method for high mountain shell river snail, comprises the following steps:
(1) put front preparation in a suitable place to breed: choose in the rice field of height above sea level between 800-1200 rice and carry out rice transplanting, and in rice transplanting process, null is set, according to every rice transplanting 6 row, 3 line space row are set and carry out, the culturing area using this rice field as river snail;
By null is set in rice field, can make the availability in rice field maximize, improve the availability in unit rice field.
(2) fertilising: stack fertilizer in the null in the rice field after rice transplanting, fertilizer is the sheep excrement after fermentation maturity, and the fertilizer amount in every mu of rice field is 80-100kg, and fertilizer is on average disperseed to stack the heap for 2-5;
The main purpose of fertilising is to cultivate plankton and pasture and water etc., and for river snail provides high-quality bait and creates good habitat, meanwhile, river snail also directly takes food the humus in fertilizer.
(3) breeding: get wild river snail on He Hu township, Qingyuan County, Zhejiang Province high mountain in the 3-4 month or June and cultivate in throwing in rice field according to Individual Size uniform distribution, in every mu of rice field, the injected volume of wild river snail is 50-100kg; The individuality that is highly greater than 3cm in the wild river snail of throwing in accounts for the more than 50% of injected volume; Between the breeding period of the 4-5 month and the 8-9 month, control water temperature at 15-25 DEG C;
The height of river snail is the maximum length of the health of river snail, and the river snail that stature is larger accounts for certain ratio, can ensure the birth rate of young spiral shell, thereby ensures the continuous output of river snail.
Due to temperature reason, river snail can breed during two of the 4-5 month and the 8-9 months, but conventionally can only breed once during these two, and the river snail of getting the 3-4 month can breed in the 4-5 month, and the river snail of getting June can breed in the 8-9 month.
(4) cultivation: during cultivation, getting length is the band fine hair browse of 30-50cm, browse is evenly placed in the null in rice field, and the lower tilt of browse is inserted in the earth in rice field, surfaced in the top of browse, after browse flavescence, treaded in earth and made fertilizer, meanwhile, changed browse with the same manner, the gradient of browse is 40-50 degree, and the depth of water during cultivation in rice field remains 25-30cm; Water temperature during cultivation is controlled at 15-28 DEG C, regularly stirs earth, keeps the fresh of earth;
(5) results: rise the March at Second Year, and the one-tenth spiral shell that the height of the river snail in rice field is reached more than 2.5cm is gathered in the crops, in rice field, below standard young spiral shell continues cultivation in the same way until ripe.Harvest time can last till early autumn, mid-October.
As preferably, the sheep excrement after described fermentation maturity is temperature more than 30 DEG C time, and sheep excrement is stacked naturally in sunny weather, on sheep excrement, water the 60%wt that the water yield is sheep excrement, then cover with Polypropylence Sheet, fermentation 14-16 days, temperature is in the time of 20-30 DEG C, and prolongation fermentation time is 25-30 days.
As preferably, during cultivation, in rice field, forbid that bird, poultry and mouse enter.
In order to improve the output of river snail, as far as possible without chemical fertilizer, if use chemical fertilizer, can use urea, composite fertilizer etc., the fertilizing amount of every mu of single is no more than 15kg.Ammonium hydrogencarbonate must not be used, otherwise mortality can be caused.
As preferably, during cultivation, the pesticide dosage in every mu of rice field is: 40%wt dimethoate emulsifiable concentrate≤25g or 40%wt orthene missible oil≤200g.
As preferably, during cultivation, within rice field 10-15 days, change water once.
As preferably, during cultivation, the pH value of water body remains on 6.0-7.0, ammonia-nitrogen content≤0.02mg/l, content of nitrite≤0.01mg/l, the total hardness≤0.10mmol/L of water.
As preferably, during cultivation, enter winter or, water level deepened to more than 30cm during lower than 15 DEG C at temperature, more whole cultivation rice field is spread and is greater than straw that 20cm is thick to improve temperature.
Compared with prior art, beneficial effect is in the present invention:
1 output is higher, and the meat of 2 river snails is better, and 3 murders by poisoning are little, and the income of 4 aquatic products is high, and 5 have reduced the utilization rate of arable area, have improved the earning rate of unit arable area.
