Description
Technical field
The present invention relates to tussah breeding technology, the 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.The protection of tussah young silkworm is educated research and has been realized twice more important technological innovation; more important technological innovation is for the first time to have realized the unification of the silkworm seed hatching of hastening the hatching of silkworms; improve method of brushing (having replaced traditional branch method of collecting ants of drawing by the paper bag method of collecting ants), set up the special-purpose nursery for 1-instar tussah silkworn of young silkworm.To improving the regularity of emerging, convenient management, reduces the loss rate of silkworm head and has brought into play huge effect; Important technological innovation is for the second time mainly the young silkworm indoor rearing technology that starts in recent years popularization, its key succeeding is to utilize the indoor management of being convenient to, can thorough disinfection diseases prevention, and can manual control temp. and humidity environment, thereby it is few to realize loss silkworm head, the healthy target of growing.The method of indoor feeding has many kinds at present, as silkworm platform is raised, heatable adobe sleeping platform is raised, insert that skill is raised, mulch film cover is raised, suspension method is raised, synthetic bag raises, raises rearing in box and support etc.The protection of outdoor booth raises that to can be said to be the indoor feeding of another kind of form in addition, has become at present the most advanced young silkworm protection and has educated technology.Related data shows, can realize the target of volume increase 20% by indoor feeding.Zhang Yuguos etc. have been reported indoor feeding result of the test of full phase of tussah at the < < Jilin agricultural > > of 2008 on the 4th phase.
The indoor rearing that tussah is raised at present becomes the hot topic of a research.But can tussah be raised the transformation that realize from outdoor raising to indoor feeding and be also far from coming to a conclusion.Realize the problem that tussah indoor feeding need to solve three aspects, the one, tussah has strong phototaxis, make progress property, fugacity feature, and indoor feeding difficulty is larger.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 current young silkworm fails to be widely used popularization.The 3rd, carry out cocoonery and the relevant input of implementing that indoor feeding brings, the artificial input of the toothed oak of gathering leaf can cause the pressure that increases cost and increase labour, and this and modern agricultural production are pursued low-cost, Labor-saving, and the target of high yield runs in the opposite direction.The stable and high yields that realizes tussah production should have the approach of two aspects: by simulating to greatest extent and creating, adapt to the suitable environment that tussah grows on the one hand, reach the object of performance tussah maximum economic benefit.Be by the improvement of Varieties of Antheraea pernyi and training are changed even to adapt to people's specific needs on the other hand, as reached, save labor, adapt to specific environment etc., thereby realize maximum economic benefit.The research of these two aspects is research direction and development trends that tussah research work is eternal.
At present, tussah is put in a suitable place to breed in the wild and is easily subject to wind, rain, low temperature, worm, bird, beast etc. and causes harm; And if employing indoor culture needs to carry out the harvesting of toothed oak leaf, increase on the one hand the harvesting of toothed oak leaf and the workload of preservation and freshness and equipment cost, on the other hand due to the toothed oak leaf preservation and freshness difficulty after plucking, easily here wither, the food value of leaf declines, and rearing is affected; And due to the plane dense breeding technology adopting now and tussah, need to ventilate feeding environment gap three-dimensional excessive, limited the natural attributes such as making progress property of tussah, fugacity.Simultaneously plane dense raises that to be conducive to the breeding of pathogen rich long-pending and propagate, so silkworm body easily falls ill, and necessarily requires higher technology management level, and the diseases prevention that often carries out disinfection has increased difficulty and the cost of diseases prevention.
Summary of the invention
The object 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, the harm of beast to tussah young silkworm, without plucking toothed oak leaf, and can give the tussah young silkworm three-dimensional feeding environment that ventilates, to overcome the deficiencies in the 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 of 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 sapling field planting, form low dry tree type, at the liftoff 10～15cm of trunk place, cut and cut down, promote 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 to pulverized limestone in the ground of plastic greenhouse, then will collect ants, the apparatus of breeding silkworms puts into canopy, with formaldehyde fumigant or Babysafe etc., carry out disinfection, and airtight 1d; In the previous day of collecting ants, the film of booth surrounding is opened, removed the taste of disinfection drug; Again silkworm seed is packed in mulberry paper bag and hastened the hatching of silkworms, go out after silkworm, mulberry paper sack is opened, with pin, newly-hatched silkworms collecting bag is fixed on to the backbone position of plant, silkworm head just can automatically be climbed the tree and look for food, and after silkworm head has been climbed the tree, paper bag is removed, and completes and collects ants; Keeping the temperature in plastic greenhouse is 16 ℃～28 ℃; 2～3d after raising to hibernating worm molting, before selecting 9 o'clock mornings of fine day or after at 17 o'clock in afternoon, silkworm head is moved on to silkworm field, field and put in a suitable place to breed.
The line-spacing in seedbed of collecting ants is 0.5m, and every two row are collected ants and between sapling, are provided with the passageway that a line width is 1m.Can conveniently manage like this.
