Utilize bionics principle and the control of the external environment condition when silkworms spin silk, can make silk connect into the plate cocoon width of cloth naturally, do not need filature to weave and form the plate cocoon sheet of the needed specific standard of people.
Because the pigment of natural colored cocoon mainly is present in the middle of the silk gum, the silk reeling technology of common cocoon has destroyed natural colouring matter and has lost meaning, and present technique is that natural colored cocoon silkworm kind kinds such as (orange, pink) pale green development and use provide the broad space.
The present invention has started the new way that the cocoon flat board is weaved silk, and Chinese silk is already opened up new development space, seeks new market, has great reality and far-reaching significance.
It is the principle of building ellipsoid cocoon shell when utilizing bionics principle and matured silkworm to weave silk that plate cocoon produces with the plane concave grid, and the silkworm plane required external environment condition of weaving silk is expanded the plate cocoon production plate that exploitation forms when open and flat to the cocoon shell.It mainly is a polymer plane concave grid, also can adopt papery plane concave grid.
Plane concave grid such as Fig. 3, Fig. 4, shown in Figure 5, plane concave grid horizontal positioned is used.
The plane concave grid comprises: plate body, a plurality of recessed lattice 2 that are concave curved surface are arranged in the plate body, and recessed lattice 2 bottom design have outage 3, are convenient to silkworm and drain fecaluria.The two ends of plate body have been designed tenon 1 and tongue-and-groove 4 respectively, are fixedly connected into bigger plane concave grid by tenon, tongue-and-groove between the plate body.Also can take other known connected mode between the plate body, as grafting, snapping, connecting plate connects, bolt connection etc.
The plate body plastics palpuses nontoxic, tasteless (plastics are advisable with polyethylene) of plane concave grid, planar section is the not exclusively transparent body of white, entire portion is wanted lubricious no hair side, add external environment condition control, the silk that makes cocoon sensation amenity only tell plane on the recessed lattice gets final product, perforation is wanted in the concave grid bottom, in order to draining fecaluria.Whole recessed lattice part is dark than the planar section color.Scheme can be: recessed lattice partly adopt pigment spraying or recessed lattice partly to add the pigment mixed injection molding.
The recessed lattice long axis of ellipse of plane concave grid shown in Figure 3 is vertically disposed, also can be transversely arranged or arranged askew or mixing.
Recessed lattice shape is by ellipsoid equation: X
2/ a
2+ y
2/ b
2+ Z
2/ C
21/2 of=1 represented curved surface decides.
Here get
For setting the recessed lattice equation of concave grid.
Promptly expression is by the ellipse on the XOY plane
1/2 of the ellipsoid that forms around Y-axis (major axis) rotation decides the shape that sets recessed lattice.A is that semi-minor axis, b are major semiaxis.
Elliptical shape can adopt following several: 2a (minor axis)=12mm, 2b (major axis)=25mm, its suitable corpusculum silkworm; 2a=18mm, 2b=30mm (the best), effect is best, is fit to arbitrarily big young silkworm; 2a=20mm, 2b=30mm are fit to individual big silkworm.
It is the hemicycle spherical shape of 28mm～30mm that the recessed lattice of plane concave grid also can adopt diameter, and it is fit to the good silkworm of all ontogeny.
Described recessed lattice center distance is 90～120mm.Outage 3 shapes of the recessed lattice of plane concave grid bottom can be circular hole, or elliptical aperture.The diameter of circular hole is 1.5mm, the major axis 2b=1.Smm of elliptical aperture, minor axis 2a=1.2mm.
Plane concave grid thickness: 3mm, the edge is 4mm.The tenon 1 at plate two ends, tongue-and-groove 4 are 40 * 40mm.
The present invention also can adopt common pure flat plastic board to carry out the plane to weave silk.Method isoplanar concave grid, different is that silkworm will be put evenly (the same concave grid of specification) pure flat moulding on the plate, all the other conditions are identical, the out-of-plane of can weaving silk, the exarate pupa nature bulk storage of formation is on plate cocoon.The advantage of the method: reduce investment outlay.Shortcoming: easily form the pollution of silkworm faeces urine or the silkworm that dies of illness and pollute plate cocoon, the silkworm pupation rate is low.
3, disinfection on silkworm rearing
All places of supporting silkworm as all apparatus and surrounding environment such as ground, wall, roof and the rearing instrument of silkworm room, a small bundle of straw, etc. for silkworms to spin cocoons on chamber, nests, all have pathogene to exist, and some pathogene can be lived for a long time under field conditions (factors).This pathogene that carries over, operation, activity by the keeper, the carrying of silkworm excrement and corpse, the flushing of rainwater is flowed, the flying upward of dust, and the food of domestic animals and fowls is drained down and is waited propagation everywhere, in case fall on mulberry leaf, silkworm body, silkworm room and the rearing instrument, by eat down, the routes of infection such as wound or body surface contact invade the silkworm body, will cause morbidity, so must thorough disinfection before breeding silkworms.
For improving Disinfection Effect, in disinfecting process, except that should pay attention to same period not, batch sterilization, " six want " accomplished in the sterilization specification requirement, promptly the silkworm room will be swept clearly, rearing instrument will be washed only, medicament will be joined accurately, soup will spray evenly, sterilization will disappear entirely, want Guan Deyan after disappearing.
(1) sterilisation step
Sterilization divides 4 steps, i.e. " sweep, two wash, three scrape, four disappear ".Preceding 3 prerequisites that step is thorough disinfection are swept, wash, are scraped to disappear and not only can eliminate big portion pathogene, and a large amount of pathogene that adhere on silkworm room, the rearing instrument are fully come out, thereby improve Disinfection Effect.
The first step is swept.Carrying out general cleaning, especially silkworm excrement accumulation place around earlier in the silkworm room wants emphasis to sweep.Then various rearing instruments in the silkworm room are moved to outdoorly, indoorly carried out general cleaning.
In second step, clean.Rearing instrument moved in the flowing water scrub, fully be exposed to the sun in the cleaning place, with good conditionsi in the silkworm room, wall and ground are all clean with flushing with clean water, and door and window will be washed and wipe clean.
In the 3rd step, batten on extortions.Ground table soil and doorway, silkworm room appearance soil in the silkworm room are scraped off 3-4 centimetre, and changed new soil.Send out sick silkworm room and will wipe the wall skin off.
The 4th step, sterilization.Advocate twice sterilization.Sterilization for the first time.The silkworm room wall whitewashes one time with 20% lime white, and rearing instrument is placed in the 2% lime white sterilization pool and soaked 30 minutes, pulls out and dries; Sterilization for the second time; Rearing instrument is moved into the silkworm room, and the silkworm room rearing instrument carries out disinfection with medicine.The fragmentary capable scalding of young silkworm tool, or with the capable steam sterilization of food steamer.The sterilization in place on every side can be arranged in for the first time to be carried out after the sterilization.Sequence of sterilization as shown in Figure 2.
