2. The feeding habit is large: the northeast tussah eats much more than the ordinary silkworm, which can not be satisfied by the ordinary silkworm rearing method. It is more convenient to adopt the mountain farming method, and it can also ensure the food requirement of tussah.
Extended data:
The characteristics of tussah:
1, long seed conservation period. The cocoon is protected from 10 to June of the following year, and the seed retention period is about 9 months (240-270 days). Go through four seasons: autumn, winter, spring and summer. Therefore, the quality of seed cocoons is required to be high, especially that there should be no tender pupae, weak pupae and developing pupae, and the temperature and humidity of the seed bank must be strictly controlled. The hatching rate of its eggs is also correspondingly low.
2, the silkworm period is early. It is10-15 days earlier than autumn silkworm, and the average temperature of young silkworm is 2 1~22℃, which is close to the optimum temperature for development. Cold damage is avoided in the big silkworm stage, especially in the 5th instar, so the temperature in the silkworm stage is suitable for the growth and development of larvae, and the cocoon establishment time is15-20 days earlier than that of autumn tussah.
3. The rapid growth and development of tussah requires strengthening management. The temperature in the silkworm stage is high, the growth and development speed of larvae is fast, and the amount of leaves eaten and digested per unit time is higher than that of autumn tussah. Therefore, it is necessary to strengthen the technical management of sericulture, evenly distribute and move silkworms in time, so as to ensure good leaves to keep food.
4, the enemy is more harmful to protect the seedlings. Early harvest of ants coincides with high temperature, and insects have strong activity ability, especially in dry years, so attention should be paid to pest control and seedling protection.
