Abstract

The invention discloses a method for breeding hairy crabs in paddy field. A series of standard method is provided from paddy field pretreatment, rice seedling selecting and planting, hairy crab protection coaming building and juvenile hairy crab throwing and feeding to water quality management and pest control, the planting characteristic of rice and hairy crab breeding characteristics are organically combined through an ecological regulation mode, the hairy crabs take aquatic animals and plants as bait in the paddy field, meanwhile, the rice seedlings take nutrients from excrement excreted by the juvenile hairy crabs in the growing period, and therefore the growth of the rice is promoted, and the win-win biology symbiosis model is achieved. Meanwhile, soybeans planted on field ridges are adopted as the protection coamings, and field space is utilized more effectively. The healthy and pollution-free breeding environment is adopted in the method, the bred hairy crabs are large in size and fresh and tender in meat quality, the fertilizing amount of the rice is reduced, adopted chemical pesticide such as insecticide and herbicide is reduced, the hairy crabs are organic and healthy, and great environmental benefits and economic benefits are brought.

Description

A kind of method of paddy field cultivation steamed crab
Technical field
The present invention relates to the cultural technique of steamed crab, especially relate to a kind of method of paddy field cultivation steamed crab.
Background technology
Yangcheng Lake steamed crab, has another name called golden pawl crab, originates in Suzhou Yangcheng Lake.Crab body is not stained with mud, and is commonly called as the large crab of clear water, and the large fat of body is fertile, the white tripe of blue or green shell, the yellow hair of golden pawl.Meat cream is greasy, and ten limbs are strong and vigorous, is placed on glass plate and can creeps rapidly.Whenever being refreshed by the cool breeze of autumn, chrysanthemum in full bloom in, busy season of golden pawl crab listing just.The female crab in lunar calendar September, the male crab in October, gonad development is best.Boil and condense, it is golden yellow that female person becomes, and male person is as white jade shape, and flavour is delicious, is to enjoy great prestige Chinese best brand of product.
Steamed crab is originally by nature cultivation, and output is limited, can not meet the demand in market.The market demand in the face of expanding day, cultivation place, aquaculture model and cultivation quality have all been subject to certain challenge, Yangcheng Lake itself is also an important Rice Cropping base, if can work out the kind breeding method that a kind of cultivation by paddy rice and steamed crab utilizes the mode of ecology regulation and control to combine, bring larger economic benefit will to local Rice Cropping and steamed crab cultivation.
Summary of the invention
Goal of the invention: lack in order to solve existing steamed crab cultivation place in prior art, the problem that aquaculture model is single, the present invention proposes that a kind of to allow steamed crab in paddy field, absorb aquatic animals and plants be bait, while rice seedling is derive nutrients from the excreta of juvenile crab discharge in vegetative period, thereby promotes the paddy field of the doulbe-sides' victory of paddy growth to cultivate the method for steamed crab.
Technical scheme: to achieve these objectives, the present invention takes following technical scheme: a kind of method of paddy field cultivation steamed crab, comprises the steps:
(1) paddy field pretreatment: the paddy field after last time plantation is finished takes thoroughly clear field to process, remove foreign material and harmful substance in paddy field, the front 20-30d of rice transplanting turns over whole to paddy field, and turning over the whole degree of depth is 20-30cm, be made into furrow face, 3-5d is exposed to the sun; With the mixture of tea seed powder and quicklime, carry out disinfection, every mu of paddy field consumption is 100-120kg; Dig out the annular crab ditch of dark 70-80cm, wide 70-80cm, the disposable fertilizer that applies, every mu of paddy field fertilising 40-50kg; After sterilization, in a circumferential field, inject fresh water, and carry out salinity adjusting; After adding salinity conditioning agent, stir;
(2) rice seedling is selected and plantation: select disease and insect resistance, rice varieties resistant to lodging, takes the planting patterns of common transplanting, and the density of plantation is 30 * 40cm;
(3) foundation of the anti-pad of steamed crab: at paddy field surrounding dense planting one circle green soy bean, to set up the anti-pad that prevents that steamed crab from escaping, plant spacing is 5cm;
(4) input of steamed crab juvenile crab and nursing: after rice transplanting, after 7-10d, carry out the input of juvenile crab, before throwing in, to juvenile crab disinfection, paddy rice water in field is carried out to the 8-9 that is adjusted to of pH, throwing in density is every mu of paddy field 800-1000; Each bait throwing in material of morning and evening every day once;
(5) water quality management: keeping the furrow face depth of water is 4-6cm, does not change arbitrarily the roasting field of water level or dehydration; According to water quality situation, every 15-20d carries out the replacing of water in field;
(6) extermination of disease and insect pest: avoid using of agricultural chemicals, adopt the insect protected medicine of bacteria agent character to carry out the improvement of damage by disease and insect.
Further, the fertilizer that described step (1) applies is one or more in soya-bean cake, sesame-send cake or colza cake.
Further, in described step (1), initial salinity is adjusted to 5-6, is down to 1-2 after 3-5d.
Further, in described step (4), the lime slurry of disinfecting with 5ppm of juvenile crab soaks 1-2h.
Further, the bait in described step (4) is graininess.
Further, in described step (6), in the insect protected medicine of bacteria agent character, contain mass fraction and be not less than 40% bacillus thuringiensis.
Beneficial effect: the method for a kind of paddy field cultivation steamed crab provided by the invention, from paddy field pretreatment, rice seedling is selected and plantation, the foundation of the anti-pad of steamed crab, the input of steamed crab juvenile crab puts forward a series of method for normalizing with nursing to water quality management and the extermination of disease and insect pest, mode by the plantation characteristic of paddy rice and steamed crab cultivation characteristic by ecology regulation and control combines, it is bait that steamed crab absorbs aquatic animals and plants in paddy field, while rice seedling is derive nutrients from the excreta of juvenile crab discharge in vegetative period, from and promote paddy growth, reached the biocenosis pattern of doulbe-sides' victory, the plantation that anti-pad employing is carried out soybean at ridge simultaneously has effectively utilized soil space especially, this method adopts healthy free of contamination breeding environment, and cultivation steamed crab stature is out large, Fresh & Tender in Texture, and the minimizing of fertilization of rice amount, has avoided the use of chemical pesticide weeding and pest-killing agent, and organic health, has brought huge environmental benefit and economic benefit.
