Demonstration household silkworm sericulture technology

1, raises a silkworm's medicine to dispose: Needs 50-55 silkworm foils, 100 silkworm nets or a complete silkworm silk Taiwan. 50 16-peak plastic enamel 160-sheet square crumbs, 3 kg bleaching powder or 3 packs of Consumerrin, 20 jins of quicklime, 1 box of chloramphenicol for silkworm use and 1 box of silkworm spirit, 1 kg of formalin, and a thermometer.
2. New and transformation of silkworm housing: The construction of silkworm housing should be conducive to the regulation of temperature and humidity, which is conducive to ventilation, light uniformity, and easy disinfection and sericulture operations. Therefore, the new silkworm sitting is best to sit on the south side of the north, the door opens in the middle of the Jamsil, the front door to open an active door and window, the rear window is centered on the opposite side of the door, length 120, width 100, sericulture with silkworm foil The length of the silkworm is 580, width is 367, indoor height is not less than 300, and 3 silkworms can be raised. The length of the silkworm rearing room is 400, 400 wide, 300 high, 800 long, 400 wide, 300 high, and 2 or 4 silkworm rearing. The interior wall of any kind of silkworm shall be painted and the top shall be sealed. . Housing transformation into the silkworm house should pay attention to whether placed pesticides, chemical fertilizers and other toxic substances, feeding small silkworm to the room downstairs as well, feeding silkworm upstairs and downstairs can be large, so that there is a rear window, interior wall painting, top seal .
3, small silkworm feeding points (1) fill the reminder green and receive ants to receive the species the day before the small silkworm temperature rose to 80, discharge harmful gases, the humidity to make up the wet and dry difference 1-2, received the silkworm species quickly after transport The dark silkworm is protected in darkness. The amount of silkworms protected in each silkworm foil does not exceed 15 pieces. The ants receive the ants by 6 o'clock in the morning and receive the leaves by 10 o'clock. Each silkworm is divided into two foils. The standard ant volume per foil is 5 grams.
(2) Selected mulberry silkworm leaves require ripening and partial tenderness, not selecting diseased leaves, larvae, damaged leaves, so that the leaf color, leaf position is the same, old and tender consistent, mulberry leaves require good care Leaf, put a wet cloth in the silkworm foil, place the mulberry leaf and then cover with a damp cloth to keep the mulberry leaf fresh.
(3) The 1st and 2nd instar silkworms should be finely cut and the petioles removed. The 3rd instar silkworms can be rough cut. The width and length of the square leaf is 1.5 times that of the silkworm body. The width of the leaves is not larger than that of the silkworm. The length and length should not be more than 3 times that of the small silkworm.
(4) Anti-drying of the film to ensure that the mulberry leaves are fresh and the humidity of the silkworms is appropriate. The 1st and 2nd instar silkworm must adopt all-dry sterilization, that is, the dry film is put in the silkworm foil, and the dry film is covered on the silkworm body. The 3rd instar silkworm adopts semi-defense dry cultivation, and only the cover is not covered.
(5) Each time the swaying seat and the splicing seat are given to the mulberry, the dense silkworm should be evenly distributed to the thin place, and the silkworm pedestal should be expanded so that the silkworm and the silkworm do not pile, and do not squeeze. At the same time, the foil was adjusted so that the whole batch of silkworm was developed neatly and consistently.
(6) Sleep treatment 2nd and 3rd instar silkworms should be given an early sleep net, usually with chest enlargement, and the silkworm body is translucent and will be screened during sleep. It is found that there are M. mori to reduce the amount of sang, and 70% have been sleeping. When the mulberry is stopped, the anti-drying film is peeled off, and the silkworm quickly sleeps. Keep quiet during sleep, avoid direct sunlight, wind and vibration, temperature down 2,95% from when silkworms can eat, leaf should be partial tender tender, the above age with leaves as a standard.
(7) The size of silkworm larvae disinfected in the silkworm silkworm is small, and disinfection is easy. The small silkworm must be controlled in a disease-free state, requiring the first-term instar ant to be sterilized with a small silkworm disease prevention No. 1 and once before sleep, disinfected once, 2 years old. , 3rd instar silkworm, age, and disinfection before sleep.
(8) To give appropriate amount to mulberry mulberry, the general rule is that mulberry mulberry should be 80% of the maximum mulberry mulberry on the day of larvae on the same day. After that, the larvae should be gradually increased, and the amount of mulberry should be reduced before going to sleep. , Each time a small amount of leaves is appropriate, give mulberry to be uniform, give mulberry 2 to 3 times a day.
(9) Jamsil environmental condition control Small silkworm stage takes temperature as the core, in accordance with the purpose of temperature to make up the temperature, take 1 and 2 instars, dry and educate at the age of 3 and 3, and dry and educate at the 3rd age. Membrane window ventilation, when using coal to make up the temperature with the exhaust pipe will exhaust the gas to the outside.
(1) Picking and storage of mulberry leaves The mature silkworm leaves with the following 5th leaf are used to avoid picking off the water leaves and wet leaves. When picking leaves, they should be lightly loaded and transported in time for storage. The mulberry leaf stacking height should not exceed 1 meter, covered with a damp cloth to prevent water loss and steaming of mulberry leaves.
(2) Diligent sand removal and dilute feeding The large silkworm era requires that sand be removed once a day at least once every other day. Each silkworm species must be raised to 50 foils on the third day of the fifth instar, and each silkworm must not contain more than 500 silkworms.
(3) Large amount of mulberry was eaten by mulberry silkworm, 85% of sorghum was eaten by 5th instar, especially the 4th to 7th day of 5th instar mulberry, and special attention should be paid to good mulberry full.
(4) There was a phenomenon of uneven size in the growth and development of silkworms in batches in Jiaqing. More than 90% of the silkworms slept when they needed to feed the leaves and feed them to the silkworms in batches. In order to achieve the orderly growth and development of large silkworms, see more than 95% of silkworms foraging.
(5) Strengthen the environmental condition of Jamsil The regulation of large silkworm period should be centered on ventilation and dehumidification, so that window sericulture during the daytime, sericulture at half-opening windows at night, and temperature increase during rainy days, we still need to open the window to eliminate humidity. Ensure the fresh air in the silkworm room.
6. Shangyu and Lizhong management (1) The upper silkworm grows and develops to the 5th instar 8-9 days, the mulberry is reduced, and a large amount of green soft manure is discharged, the chest is transparent, the silkworm body is shortened, and the tail has 2 - 3 soft feces, the head swinging left and right, some silkworms climbed around the silkworm, which is the appropriate period of the Shangyu. For silkworm households using plastic folding and square gridding, the time for the captivity should be late.
(2) The required cooking utensils for a silkworm species are 50 plastic plackets, 160 grid rakes, and 50 grass rakes.
(3) Suizhong manages a total of 500 silkworms on 16 peaks, 500 silkworms on one grass, 150 to 160 silkworms on one grid, and temperatures on the first and second days after the last time. 76-77, reduced to 74-75 two days later; moisture in the cockroach middle, wet and dry in cocklegrass is 5-7, spring silkworm, late autumn should pay attention to silkworm cocoon is too dry, to prevent knotting, summer silkworm, early autumn silkworm or rainy weather Pay attention to warming, ventilation, and evacuation so as to avoid contamination of cocoon; the diverticulum should keep the light dark and uniform, prevent direct sun and strong wind from blowing straight; the upper two days must travel to the mountains and silkworms to be lifted separately, and strengthen the ventilation after three days Air humidity.
7. The rake is sold out in the normal hustle and bustle. The protection can be collected on the 7th day of the last day. When picking oysters, they must be light and easy to put in order to avoid hemorrhagic contamination of the oysters. They should be classified as picking, picking and picking, and classifying and selling them (that is, they can be divided into positive, inferior, and lower). Lots are sold in batches, sold out in batches, and are not sold for foot gauntlets and tides. When selling, it is necessary to use baskets to install them, so that light shipments can be carried out to prevent the steamed scallops of fresh oysters from affecting tannin quality.
