Abstract
The invention relates to two housefly larvae feeds. The invention is characterized in that: one of the housefly larvae feeds comprises 0.001 to 6.5% of sodium silicate and 93.5 to 99.999% of common housefly larvae feed in percentage by mass; and the other feed consists of 0.001 to 4.0% of potassium silicate and 96 to 99.999% of common housefly larvae feed in percentage by mass. The housefly larvae feeds comprising the sodium silicate or the potassium silicate additive can greatly improve the utilization of the feeds and achieve the aim of increasing both production and income, thereby being used for the artificial breeding and even in the commercial process.
Description
Technical field
The present invention relates to two kinds of housefly larvae feeds, relate to contain the housefly larvae feeds of sodium metasilicate or potassium silicate specifically.
Background technology
Housefly is a kind of people's of disturbing a sanitary insect pest; Also be a kind of resource insect of propagating artificially simultaneously; Can be the mankind provides " antibacterial peptide " and some natural polymers of good animal protein, high-strength bactericidal action; Like chitin, shitosan etc., so the breed of housefly receives people's attention day by day, it is propagated artificially and even suitability for industrialized production also has report.But in the propagating artificially of common house-fly grub (claiming fly maggot again), exist the not high problem of conversion ratio of feed, discover to raise in the remaining feed of fly maggot to still have a lot of unemployed nutriments.Improving breed efficient and efficiency of feed utilization, obtaining high yield is that urgent problem is cultured in the housefly industrialization.

3) be colourless, as to have a little look transparent or semitransparent granular solids.Sodium metasilicate is colourless, as to have a little look transparent or semitransparent liquid in the system that with water is dispersant.Sodium metasilicate extensive use in chemical system, light industry, in the mechanical industry, building trade agriculturally can be made silicon element fertilizer material etc.
(chemical formula is the solid potassium silicate: K
2SiO
3) be that colourless or little yellow is translucent to clear glass shape thing, hygroscopicity is arranged.Potassium silicate is colourless, as to have a little look transparent or semitransparent liquid in the system that with cold water is dispersant.Its purposes comprises protective finish (preventing that " frosting " is the salt surface crystallization); Catalyst, binder; Make in glass, the pottery and be used as detergent; Phosphor is gluing on picture tube, is coated with the welding rod outside, can overcome splatter etc.
But the achievement that improves the fly-maggot feed utilization rate through the method for in fly-maggot feed, adding a certain amount of sodium metasilicate or potassium silicate is not appeared in the newspapers.
Summary of the invention
The objective of the invention is in same inventive concept, to provide two kinds of efficient, cheap housefly larvae feeds.
The present invention is through adding sodium metasilicate or potassium silicate as additive in housefly larvae feeds commonly used; Obtain two kinds of housefly larvae feeds; After these two kinds of feeds of process are fed respectively, all can significantly improve the output of fly maggot raising and the utilization ratio of feed, thereby realize the object of the invention.
A kind of housefly larvae feeds of the present invention, by gross mass mark 100%, sodium metasilicate by 0.001%～6.5% and 93.5%～99.999% housefly larvae feeds component are formed.
Another kind of housefly larvae feeds of the present invention, by gross mass mark 100%, potassium silicate by 0.001%～4.0% and 96.0%～99.999% housefly larvae feeds are formed.
The housefly larvae feeds that contains sodium metasilicate of the present invention, by gross mass mark 100%, the amount of preferred sodium metasilicate is 0.1%～6.5%, the amount of housefly larvae feeds is 93.5%～99.9%.The amount of further preferred sodium metasilicate is 2.4%, and the amount of housefly larvae feeds is 97.6%.The housefly larvae feeds that contains potassium silicate of the present invention, by gross mass mark 100%, the amount of preferred potassium silicate is 1.0%～3.5%, the amount of housefly larvae feeds is 96.5%～99.0%.The amount of further preferred potassium silicate is 2.8%, and the amount of housefly larvae feeds is 97.2%.
Housefly larvae feeds component during the housefly larvae feeds that contains sodium metasilicate or potassium silicate of the present invention is formed is housefly larvae feeds commonly used, can be by wheat bran and water according to mass ratio 30～40: 60～70 form.
The preparation method of two kinds of housefly larvae feeds of the present invention is usual ways, can fully mix several components together, as long as guarantee mixing; For each component is fully mixed, also can fully be dissolved in sodium metasilicate, potassium silicate in the water after, mix with wheat bran again, when particularly the additive of low dosage uses, preferably earlier that it is soluble in water.
Utilize sodium metasilicate or the potassium silicate of containing of the present invention as the housefly larvae feeds of the additive common house-fly grub of feeding; Compare with the contrast of the housefly larvae feeds that does not add sodium metasilicate or potassium silicate; The biological yield that the housefly larvae feeds of identical weight obtains; What contain that sodium metasilicate or potassium silicate feed as the housefly larvae feeds of additive is not add 1.2～2.7 times that the contrast of sodium metasilicate or potassium silicate is fed; The conversion ratio of wheat bran is 1.2～2.7 times of contrast that do not add sodium metasilicate or potassium silicate, has significantly improved the utilization rate of feed, has reached the purpose of increasing both production and income.Utilize forage feed of the present invention simultaneously, the fly maggot that can avoid raising is outwards escaped, and has reduced workload.And this additive-sodium metasilicate or potassium silicate to the survival of fly maggot, pupate, laying eggs etc. of the emergence of pupa and emergence adult thereof all have no adverse effects, and this additive is inexpensive.
