Description
Technical field
The present invention relates to the method for brushing that a kind of silkworm artificial feed breeds silkworms, belong to silkworm cultural technique field.
Background technology
It is that the newly-hatched silkworm just having hatched is collected into the process in rearing instruments such as raising box from newly-hatched silkworms collecting bag that silkworm is collected ants.At present, newly-hatched silkworm mulberry leaf are educated method of brushing and are mainly contained the dark bag of newly-hatched silkworm technology, the newly-hatched silkworm net method etc. of collecting ants of collecting ants.
Dark bag of technology of collecting ants of newly-hatched silkworm, as field gold congruence in " modern agriculture science and technology " 2011 24 the method as described in interim, first absorb water a little with spread pen or rayon balls, be coated with wet paper four limits of collecting ants, then a people to pin newly-hatched silkworms collecting bag motionless, with the hands thumb of another people, forefinger is clamped respectively two angles of the paper minor face of collecting ants, connecting gently silkworm band paper tears, turn over and be placed on the silkworm plaque central authorities that are covered with plastic film, then a people with the hands eats, thumb is clamped respectively newly-hatched silkworms collecting bag both sides, aim at the newly-hatched silkworm central authorities of having collected, ovum faces down, one people pats newly-hatched silkworms collecting bag black flour gently with silkworm chopsticks, finally gently sweep with chicken feather the newly-hatched silkworm being scattered, concentrate on and collect ants on paper.
The newly-hatched silkworm net method of collecting ants, as Yang Xuegao " Crop Diseases in Yunnan " 2007 the 8th interim as described in, be put into and calm down kind above with a subnetting, spread on the net with the mulberry leaf that cut, after 15 minutes, treat that newly-hatched silkworm all climbs on mulberry leaf, then mention silkworm net and be put into above rearing instrument, income is complete.
Said method is the method for brushing that mulberry leaf are bred silkworms, and mulberry leaf are bred silkworms and must could be bred silkworms season at the applicable growing of mulberry of weather conditions (temp. and humidity etc.), and other season is if winter is owing to not having mulberry leaf to breed silkworms.
Artificial feed are bred silkworms and are referred to that the mash feed forming with cooperations such as mulberry leaf powder, soybean meal, starch, Vc, mineral salt is in harmonious proportion evenly by a certain percentage with water, pack in freshness protection package, in steam rice cooker, cook, after cutting into inch strips with blade after cooling completely, feed silkworm, the benefit that artificial feed are bred silkworms is to be not to be subject to effect of natural conditions can realize throughout the year to breed silkworms.
At present, the artificial feed following several method of having collected ants:
Newly-hatched silkworms collecting bag covers on feed and allows newly-hatched silkworm climb to voluntarily on feed, if Feng Jianqin is described in " silkworm and mulberry circular " second phase in 2005, while collecting ants, tear newly-hatched silkworms collecting bag, the one side that has silkworm is put on feed, allow silkworm climb to voluntarily on artificial feed, after most of newly-hatched silkworm has climbed on artificial feed, remaining a small amount of newly-hatched silkworm is hit down on feed with silkworm chopsticks.
In Ministry of Agriculture website " young silkworm artificial feed are educated technical regulation altogether " described in 7.4, artificial feed method of brushing has following two kinds of methods: newly-hatched silkworms collecting bag collect ants (method one), collect ants and cut after putting and carry out immediately at feed, while collecting ants, tear newly-hatched silkworms collecting bag, the one side that has newly-hatched silkworm is placed on feed, after allowing silkworm climb to voluntarily on feed, remaining a small amount of newly-hatched silkworm is hit down on feed with silkworm chopsticks.Paper bag method is collected ants (method two), while collecting ants, the silkworm on the paper of parcel is hit down on feed with silkworm chopsticks, and the silkworm on packing paper and chorion are poured on feed in the lump.Wherein paper bag method is collected ants and is required higher to incubation rate on the one of silkworm egg.
The shortcoming that several artificial feed method of brushing exist is above as follows:
1, take a lot of work bothersomely, must need two people to operate above simultaneously, and waste feed.
2, easily hinder silkworm, frightened silkworm, cause the thin hair of silkworm rate low, make the teaching of breeding silkworms.
3, newly-hatched silkworm distribute serious uneven, and cannot even silkworm, cause silkworm to grow irregular.
Particularly the paper of collecting ants that has newly-hatched silkworm is placed directly on feed and is collected ants, although the method is simple to operate, because newly-hatched silkworm stature is little, the paper of collecting ants can not be completely and is raised the plane contact of feed in box, cause newly-hatched silkworm in same time section, to take food, cause silkworm to grow irregular.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of silkworm artificial feed's method of brushing is provided.
Term explanation
