Description
Technical field
The invention belongs to the store method of silkworm silkworm seed, specifically be a kind of be suitable for hastening the hatching of silkworms in the first cross silkworm egg postpone the method for hatching.
Background technology
Silk is the Ancient Chinese greatness invention in generation, and becomes the cultural Symbol that China has world's influence.Planting mulberry and breeding silkworm have the history more than 5000 in China, still are to use new fresh mulberry leaf to breed silkworms at present, and this is natural, a precious important symbol of silk product.Based on this technical characterictic, in the now domestic and international silk cocoon large-scale production process, in order to make full use of mulberry leaf; Also in order effectively to prevent flacherie; Sericulture production in various climatic regions all relies on the tight plan silkworm egg brooding time of a cover, and its main points are to make the growth of growth and mulberry tree of silkworm synchronous; Be unlikely to because of sericulture causes very much afoliate morning, the reason sericulture is not too late yet causes mulberry leaf to wear out and sericulture later stage and other crops production generation recruitment and control of insect medication contradiction.Yet along with the aggravation of Global climate change, anomalous weather occurs frequent in recent years; Often because of spring low temperature or high temperature, Changes in weather such as emergent late frost and freeze injury cause in the silkworm egg hatching process, occurring the ANOMALOUS VARIATIONS that mulberry leaf are grown; Or even mulberry leaf growths destroyed, and has to change the time started of breeding silkworms, if can not in time adjust the time started of breeding silkworms; Then cause the waste of serious afoliate or silkworm egg, influence the sericulture income.
At present, cold storage of silkworm egg suppresses technology, is after utilizing the silkworm seed termination of diapause, and body early embryo (before third embryo of silkworms) has stronger tolerance to low temperature, regulates the production time.But silkworm egg is in case come out from freezer; After (be the word of sericulture specialty hasten the hatching of silkworms processing) handled in the hatching that begins to heat; Because developmental embryo is poor to the resistance of low temperature environment,, needs to postpone and collect ants the time even run into anomalous weather; Existing technical measures also can only be regulated 3-5 days time, and cold preservation time is long to be occurred dead germ easily and hatch bad.Go back more effective, the safer method of neither one in the silk cocoon production and suppress the silkworm seed embryonic development, postpone brooding time more than 10 days, this has greatly influenced the safety of breeding silkworms and producing.
On the other hand, between the silkworm feeding period, the large and small silkworm death by accident because of pesticide poisoning, flacherie or other reasons all can take place in various places, and do not provide as there being the silkworm egg that hastened the hatching of silkworms timely this moment, with causing the silkworm raiser who goes wrong to lose receipts.Simultaneously, because of can't regulating brooding time, raise the rich and influential family and can not rationally arrange to raise quantity according to the actual conditions of self, reach should make full use of favourable season, mulberry leaf are bred silkworms more, avoid the purpose of labour, apparatus contradiction again.Some areas will be carried out the adjustment of silkworm rearing season layout as increased by two spring raising etc., and are normal because of not providing suitable silkworm egg supply to implement.
For this reason; Invent a kind of do not influence the silkworm incubation rate with grow; The flexible middle egg-incubation time method of hastening the hatching of silkworms; For effective reduction natural calamity and thermic anomaly the influence of mulberry leaf growth and silkworm are poisoned and the influence of disasters such as flacherie to silk cocoon production; The balance, raising sericulture productivity effect and the sericulture safety that improve sericulture quantity and mulberry leaf output have important value, also for availability, the flexible silkworm rearing season layout that improves the first cross silkworm egg effective way are provided simultaneously.
