Co-rearing technique of young silkworms

As the saying goes, "the young silkworms are well reared for 70% of the harvest." Therefore, special attention should be paid to the co-rearing of young silkworms.

(1) specific requirements and technical measures for co-rearing of young silkworms

1. A special small silkworm room is used in the co-breeding room. It needs good heat preservation and moisturizing performance, and it is easy to change air. Strictly disinfect and carry out "three disinfection and one fumigation" before @ # @ 250mm. "Sanxiao": the first time to use lime paste; the second time to use bleach; the third time to use disinfectant; "one fumigation": to dissipate the smoke with poison.

two。 Heating is unified as Kang bed heating. Due to the heating of the Kang bed, the silkworm seat has the advantages of uniform temperature sensing, good heat preservation performance, easy moisturization, and will not produce bad gases such as carbon monoxide and sulfur dioxide. But it must be noted that for 3 days before ant harvest, the Kang bed should be tried to burn, find out the law of heating, cooling and moistening, eliminate disinfection gas and moisture in the co-nursery room, and check the flue for smoke leakage.

3. Control the temperature and humidity of each age: generally 1 or 2 years old, the temperature is 26Mel 27 ℃, the humidity is 85% Mel 90% the temperature of the 3rd age is 25 Mel 27 ℃, the humidity is 75% Mel 80%.

4. Advance seat expansion: due to the rapid growth of small silkworms, in order to make silkworms fully fed and develop healthily, it is necessary to expand seats in advance combined with each mulberry situation.

5. Do a good job of getting up and sleeping: sand removal can not only keep the silkworm seat clean and hygienic, but also an important disease prevention and health care measure in the process of feeding, especially in the high temperature and humid environment of young silkworms.

6. Correct use of medicine for young silkworms: during the period of small silkworms, alternately use Panax notoginseng bran and anti-stiff powder in the morning and evening.

7. Pay attention to the preservation of mulberry leaves: 1, 2-year-old total anti-drying, 3-year-old using semi-dry.

(2) benefits of co-rearing young silkworms

1. The work of co-rearing young silkworms is generally undertaken by some large sericulturists, who are experienced in sericulture and are guaranteed to raise young silkworms, laying a solid foundation for a bumper harvest for sericulture farmers.

two。 It is beneficial to the popularization of technology. The co-rearing of young silkworms relatively reduces the scope of work on the surface, so that the new technology of sericulture can be popularized and applied in time.

3. It helps to save costs. The implementation of joint household rearing of small silkworms does not require the investment of special silkworm rooms and other small silkworm equipment in every sericulture household, which not only reduces the capital construction, but also saves the production cost, such as fuel, disinfection and so on.
