Description

Rearing method of tussah young silkworm and device
Technical field
The present invention relates to the tussah breeding technology, rearing method of especially a kind of tussah young silkworm and device.
Background technology
The technical research of keeping a full stand of seedings of relevant tussah young silkworm is the emphasis of tussah production technology research always.Tussah young silkworm protection is educated research and has been realized reforming than important techniques for twice; Be to have realized the unification of the silkworm seed hatching of hastening the hatching of silkworms for the first time than the important techniques innovation; Improved method of brushing (having replaced traditional branch method of collecting ants of drawing), set up the special-purpose nursery for 1-instar tussah silkworn of young silkworm with the paper bag method of collecting ants.To the raising regularity of emerging, convenient management reduces the loss rate of silkworm head and has brought into play enormous function; Important techniques innovation for the second time mainly is to begin the young silkworm indoor rearing technology promoted in recent years; The key of its achieving success is to utilize the indoor management of being convenient to, can the thorough disinfection diseases prevention, can artificially control the temp. and humidity environment; Thereby it is few to realize losing the silkworm head, the healthy target of growing.The method of indoor feeding has many kinds at present, as the silkworm platform raise, heatable adobe sleeping platform is raised, insert that skill is raised, the mulch film cover is raised, suspension method is raised, synthetic bag is raised, raised rearing in box and supports etc.Outdoor in addition booth protection is raised and can be said to is the indoor feeding of another kind of form, has become at present the most advanced young silkworm protection and has educated technology.Related data shows, can realize increasing production 20% target through indoor feeding.Zhang Yuguos etc. have been reported indoor feeding result of the test of full phase of tussah 2008 " Jilin agricultural " on the 4th phase.
The indoor rearing of tussah raising at present becomes the hot topic of a research.But can tussah be raised and realize also being far from coming to a conclusion from the transformation of outdoor raising to indoor feeding.Realize that the tussah indoor feeding need solve the problem of three aspects, the one, tussah has strong phototaxis, make progress property, fugacity characteristics, and the indoor feeding difficulty is bigger.The 2nd, the gathering of toothed oak leaf, fresh-keeping, storage be difficulty comparatively, and this is the major reason that the indoor protection technology of educating of present young silkworm fails to obtain extensive penetration and promotion.The 3rd, carry out cocoonery and the relevant input of implementing that indoor feeding brings, the manual work input of the toothed oak of gathering leaf can cause and increase cost and the pressure that increases the labour, and low-cost, laborsavingization are pursued in this and modern agriculture production, and the target of high yield runs in the opposite direction.The stable and high yields that the realization tussah produces should have the approach of two aspects: adapt to the suitable environment that tussah grows through simulating to greatest extent and creating on the one hand, reach the purpose of performance tussah maximum economic benefit.Then be to change the specific needs that adapts to people even on the other hand, as reach and save labor, adapt to specific environment etc., thereby realize maximum economic benefit through improvement and standardization to the tussah kind.The research of these two aspects is eternal research direction of tussah research work and development trend.
At present, tussah is put in a suitable place to breed in the open air and receives wind, rain, low temperature, worm, bird, beast etc. easily and cause harm; And if the employing indoor culture then need be carried out the harvesting of toothed oak leaf, increase the workload and the equipment cost of the harvesting and the preservation and freshness of toothed oak leaf on the one hand; On the other hand because the difficulty of the toothed oak leaf preservation and freshness after plucking; Here wither easily, the food value of leaf descends, and raises achievement and is affected; And because the plane dense breeding technology that adopts now and tussah need be ventilated the feeding environment gap of solid is excessive, limited natural attributes such as making progress property of tussah, fugacity.It is rich long-pending and propagate that simultaneously plane dense is raised the breeding that helps pathogen, so the silkworm body falls ill easily, necessarily requires higher technology management level, and the diseases prevention that often carries out disinfection has increased the difficulty and the cost of diseases prevention.
Summary of the invention
The objective of the invention is: rearing method and device that a kind of tussah young silkworm is provided; It can not only effectively avoid wind, rain, low temperature, worm, bird, beastly harm to the tussah young silkworm; Need not to pluck the toothed oak leaf, and can give the feeding environment that the tussah young silkworm is ventilated solid, to overcome the deficiency of prior art.
The present invention is achieved in that the rearing method of tussah young silkworm; Set up a plastic greenhouse, the plantation sapling of collecting ants in plastic greenhouse, the per kilogram silkworm seed amount seedling age of need planting is sapling 150~200 strains of collecting ants in 3~4 years; The sapling spacing in the rows of collecting ants 0.3~0.4m forms the seedbed of collecting ants; Collect ants after the sapling field planting, form low dried tree type, cut at the liftoff 10~15cm of trunk place and cut down, the promotion collateral generation, 5~6 of side shoots are stayed in every strain, and the sapling of collecting ants is liftoff, and 50~60cm place flat-top cuts cuts down; Before sericulture, in 3~5d one deck is spread with pulverized limestone in the ground of plastic greenhouse, will collect ants then, the apparatus of breeding silkworms puts into canopy, carry out disinfection with formaldehyde fumigant or Babysafe etc., and airtight 1d; In the previous day of collecting ants the film around the booth is opened, removed the taste of disinfection drug; Again silkworm seed is packed into and hastens the hatching of silkworms in the mulberry paper bag, go out silkworm after, the mulberry paper sack is opened, with pin newly-hatched silkworms collecting bag is fixed on the backbone position of plant, the silkworm head just can be climbed the tree automatically and looked for food, treat that the silkworm head has been climbed the tree after, paper bag is removed, completion is collected ants; Keeping the temperature in the plastic greenhouse is 16 ℃~28 ℃; 2~3d behind raising to the hibernating worm molting selected before 9 o'clock fine mornings or after at 17 o'clock in afternoon the silkworm head is moved on to open-air silkworm field to put in a suitable place to breed.
