Description

Fly maggot method for large scale cultivation and equipment

The invention belongs to fly maggot captive breeding technical field, in particular a kind of method for large scale cultivation of fly maggot and equipment.

Along with the continuous increase of human society to the protein energy demand, seeking new protein source, to be used to satisfy human wants be one of problem of world today's property.In recent years, insect is more and more paid attention to by people as new protein source, and especially the development and use of housefly are more noticeable.Housefly with short production cycle, the reproduction coefficient height, larva is nutritious, is suitable for large-scale production.Domestic development and use about housefly start from the initial stage eighties, but according to the data record, great majority just utilize the ight soil of aquaculture, extract the supplement feed of regeneration protein feed as livestock and poultry.As seen, fly maggot is as the research and development of high-quality protein, only is in the primary stage as the animal feed source, also do not reach the degree of stable industrialized aquaculture.

The objective of the invention is to design one and supporting have a daily output of certain fly maggot large-scale farming technical method and equipment, make a living protein feed production matter and edible protein provide raw material.This supporting technology comprises the content of following aspect: fly maggot large-scale farming equipment; Plant the preparing process of maggot feed, one-tenth fly bait and commodity maggot feed; The breeding technique flow process and the management regulation of become fly, planting fly and commodity maggot.

Technical scheme of the present invention is as follows:

Fly maggot large-scale farming equipment is made of with Polypropylence Sheet, collection ovum Polypropylence Sheet, sponge closed one-tenth fly rearing-box, emergence pallet, connection cloth bag, dress feed, and rearing-box places receptacle, and the larva culture device is made of larva incubator and larva culturing room.The larva incubator places in the larva culturing room.It is closed becoming the fly rearing-box, and single size range is: long (100-150) * wide (70-80) * height (45-50) cubic centimetre, long 30 centimetres of case leg.Every becomes fly to occupy space 8-9 cubic centimetre, and the framework of case is made by metal or industrial plastic, and periphery is inlayed separation net, and dress feed Polypropylence Sheet, collection ovum Polypropylence Sheet are set in the rearing-box, and drinking-water places the casing upper isolation online with the sponge full of water.The collection ovum with the wheat bran that 70% loose shape is set on the Polypropylence Sheet as laying eggs pad.The fly maggot incubator is made by industrial plastic, and the size range of single incubator is (50-90) * (40-60) * (20-25) cubic centimetre.

Plant maggot, become bait and the feed compound method of fly and commodity maggot as follows:

Kind of maggot composts or fertilisers of cultivating is prepared by following component and method: get the groundnut cake that contains moisture 70%, put at normal temperatures 4 hours, add 0.1% trace element and 3% bone meal during use.Become fly bait to prepare in following ratio: 50 parts in brown sugar, 25 parts of fish meal, in 25 parts of 110 ℃ of bean powderes of heating 10 minutes, 5 parts of hepar siccatums, 10 parts of mixing of yeast stir.The feed of commodity maggot is prepared by the following method: get the buffer solution that moisture 70% groundnut cake adds PH5.5 and be modulated to humidity 80%, stir.The buffer solution compound method of PH5.5 is as follows: get NaH ₂PO ₄71.6mg and Na ₂HPO ₄Be modulated into mother liquor 31.2mg add 1000ml water respectively, then, take out 94ml and 6ml more respectively and mix, add 8 gram salt, add 1000ml water again, promptly be modulated into the buffer solution of PH5.5.

Become the management regulation of fly, kind fly and commodity maggot as follows:

(1) when each cultures the circulation beginning, cleaning receptacle and fly rearing-box;

(2) get ready brown fly pupa 1500 grams, be roughly equal to 45000 pipunculid pupas, put into the emergence pallet, with the connection cloth bag pallet is connected with the bottom half valve, open the valve plate, emergence begins to take off the connection cloth bag to finishing to shut valve after about 3 days certainly;

(3) sprout wings when pupa and began about 6 hours,, put the drinking-water sponge in outer online place of case simultaneously putting on the Polypropylence Sheet of dress bait about bait 20 grams;

(4) after this, change drinking-water every day, take out residual bait, put into new bait;

(5) become the fly post-coitum to begin to insert the pad of laying eggs next day, take out the pad of laying eggs after 24 hours, the pad of will newly laying eggs is inserted, and will fill up with laying eggs of ovum and put into commodity maggot or kind maggot incubator;

(6) screening fly pupa is done to produce following batch and is become fly usefulness, and lays eggs the 7th day the one-tenth fly, and the fly pupa is inserted the circulation pallet, and to carry out planting the first time fly additional.

Plant fly feeding and management by the following method:

(1) in the process that becomes fly to raise, the 5-7 that gets ovulation criticizes and carries out the population cultivation, makes it to turn to pupa;

(2) between culture period, kind maggot culture environment condition is: temperature 27-33 ℃, medium humidity will be stirred in 70%, 3 day less, and in time adds feed;

(3) used sieve method, and isolated good, the of the same size pupa of color and luster as kind of a pupa, the weight of 35-40 pupa is 1 gram;

(4) pupa is put into the emergence pallet and is sprouted wings, when needs are preserved, can be below 12 ℃, and conserving species pupa under relative moisture 70% condition.

The feeding and management by the following method of commodity maggot:

(1) in becoming the fly feeding process, from becoming the fly ovulation, every day, the pad of will laying eggs took out from one-tenth fly rearing-box, inserts the larva incubator, and adds feed on a small quantity during 13-14;

(2) place commodity maggot incubator between 25-37 ℃, casing do not want under the condition of sunlight direct projection;

(3) when the commodity maggot grows into the 4th day, mix with residue with thin wooden chaff, sieve, the commodity maggot is separated;

Use again when (4) the wooden chaff after the separating treatment can separate next time.

Embodiments of the invention can be according to above-mentioned technical specification design fly maggot method for large scale cultivation and equipment.

The present invention concludes and combines fly maggot large-scale farming process system flow chart, as shown in drawings.The fly maggot feeding facility must meet the following conditions: become fly receptacle environmental condition to be: temperature 25-33 ℃, and illumination 10-12 hour, relative moisture 70%, wind speed is one to the secondary flow state.The larva raising condition is: temperature 25-35 ℃, and medium humidity 70%.Above condition can realize with fluorescent lamp and humidifier.

The commercial index of native system is: single case daily output 7-10 jin; Raising scale can strengthen with casing.

The present invention has following beneficial effect:

The first, for the large-scale development housefly larvae protein has proposed the orderly technological process of production, separate The insurmountable raising circulatory problems in the design of having determined in the past changes the small-scale raising pattern of fly maggot over to Be not subjected to loop limit, systematized extensive raising.

The second, technical solution of the present invention is housefly ecology, reproductive biology and nutritional physiology and big The result of large-scale production basic technology comprehensive utilization. For feed industry reaches in the future human food's albumen system Making provides the output that meets trophic level and sanitary standard huge controlled commodity maggot.

Three, the present invention compares with Design Mode in the past and has the advantage that quantum of output is big, cost is low, The fresh food that can be used as at present prawn, chiefeconomic fish enters feed market, and can receive good Economic benefit.
