Standards and techniques for rearing young silkworms

The key to raising young silkworms is to master reasonable temperature and humidity, ripe fresh mulberry leaves and reasonable sleep treatment techniques.

Leaves for collecting ants, yellow and greenish in color, slightly wrinkled, 2 leaves in spring, 3 leaves in summer and autumn, 3 leaves in 1 year old, yellowish green in 1 year old, flat leaves, 4 places in 3 mo leaves, suitable for tender rather than old, depending on climate, 2-year-old mature leaves with normal green color, 3-year-old spring can use three-eye leaves. 1Mel 2-year-old cut leaves are square leaves 1.5 times the length of silkworm body, and striped leaves are used for expanding seats.

The spring silkworm period can master 10 days of sleep, the time of high temperature can be appropriately shortened to promote the development of the silkworm, and the vast majority of silkworms can be raised in batches after sleeping. The rate feeding should be carried out under the condition that there is almost no sleeping silkworm. In principle, the mulberry should be stopped late, and the small silkworm period should be given to mulberry in combination with the small silkworm period. Ventilation should be carried out 2 times a day, not less than 10 minutes each time, and the humidity should be heated at the same time. The co-rearing of young silkworms is required before the 3rd instar.
