Feeding small silkworm skills

Temperature and humidity control 1 to 3 years old is called small silkworm, and the environment required for small silkworms is high temperature and humidity. 1~2 instar suitable temperature 26 °C ~ 27 °C, relative humidity 90%; therefore 1 ~ 2 instar silkworm adopts full-defense dry cultivation, namely the plastic film under the cover; 3 age with semi-defense dry education, namely only cover does not pad Plastic film, keeping the temperature at 26 °C ~ 27 °C, relative humidity 85%.

1st instar mulberry leaves from the top of the first 3rd leaf, yellow in leaf color with green, 1 silkworm species of silkworm, with 1 kg of leaves; 2 instar 4th leaf from the top end of buds, leaf color in green With yellow, a silkworm leaves 3 kilograms; 3 ages from the top buds number 5 to 6 leaves, leaf color green, shiny, a silkworm leaves 10 to 12 kg; 1 to 2 instar silkworm will mulberry The leaves were cut into small squares 1.5 times longer than silkworms. The 3rd instar silkworm mulberry leaves were roughly cut into triangles and fed. Each time the mulberry amount should be controlled, the left mulberry silkworm should be left with a small amount of residual mulberry for the next time.

Feeding mulberry times and times 4 times a day, respectively, time is 7 am, 11 noon, 4 pm, 10 pm; small silkworm growth and development fast, each feeding mulberry to combine expansion.

Treatment before sleep is to remove sand before sleep. The body color of the silkworm is changed to white, the body is shortened, and the body surface is intense and bright. When silkworm silkworm silkworm is adhered to part of the silkworm body of the first instar silkworm, the silkworm excrement can be adhered to the silkworm body of the first instar silkworm. sand. The second is to mention green. If a portion of the silkworm has slept, and part of it has not slept, it should be added to the mulberry once again. The silkworm will be brought up and moved to another pupa to continue breeding.

During the pre-sleeping period, the silkworms should be dry. The lime powder should be sprinkled on the silkworms to keep the relative humidity at 80%. When there is cocoon, the room should be wet and the relative humidity should be 85%. If the humidity is not enough, it can be used to sprinkle water on the ground. wet.

Sleeping and feeding When 95% of the sleeping silkworms have been molted, the head turns from gray to brown, and the head becomes significantly larger. The young silkworm crawls and finds food. At this time, it can feed. Foraging mulberry leaves should be slightly tender, giving mulberry should be less.
