Breeding method and device for young tussah

Abstract

The invention discloses a breeding method and a breeding device for young tussah. A greenhouse is built, hatching tree seedlings are planted in the greenhouse, and a hatching seedling bed is formed; after the fixed planting of the hatching tree seedlings, the hatching tree seedlings are bred into low-trunk tree forms, and 5 to 6 branches are left for each strain; graine is loaded into a kraft paper bag for hastening the hatching of silkworms, after the breakthrough of young silkworms, an opening of the kraft paper bag is opened, after the silkworm head tree climbing completion, the paper bag is removed, and the hatching is completed; the temperature in the greenhouse is maintained at 16 DEG C to 28 DEG C; the young silkworms are fed to 2 to 3 days at the molting of primary sleeping silkworms, and the silkworm heads are moved to a field silkworm plant for breeding outside cages before 9 o'clock in the morning or after 17 o'clock in the afternoon in sunny days. The young tussah is bred through adopting a mode of building three-dimensional breeding environment in rooms, the harm to the young tussah caused by natural environment and natural enemy can be effectively prevented, the labor work for picking and storing oak leaves is also avoided, the ventilation three-dimensional breeding environment is provided, the natural attributives of upward climbing habit, scattering habit and the like of the tussah are met, the disease rate of the silkworm body is reduced, the management requirement is reduced, the disease prevention difficulty and the cost are reduced.

Description

technical field [0001] The invention relates to tussah silkworm breeding technology, in particular to a method and device for raising tussah silkworms. Background technique [0002] Research on tussah silkworm seedling preservation technology has always been the focus of tussah silkworm production technology research. Two important technological innovations have been achieved in the research on the protection and breeding of tussah silkworms. The first important technological innovation is the unified accelerated greening and hatching of silkworm eggs, and the improvement of the method of collecting ants (replacing the traditional method of collecting ants with paper bags). Introduced branches to collect ants), and established a special nursery for small silkworms. It has played a huge role in improving the uniformity of seedling emergence, facilitating management, and reducing the loss rate of silkworm heads; the second important technological innovation is mainly the indo...

Problems solved by technology

In order to achieve indoor breeding of tussah silkworms, three problems need to be solved. One is that tussah silkworms have strong phototaxis, upward and dispersive characteristics, and it is difficult to raise them indoors.

The second is that it is difficult to harvest, keep fresh, and store oak leaves, which is an important reason why the indoor protection and breeding technology of small silkworms has not been widely popularized.

The third is the investment in silkworm houses and related implementation brought by indoor breeding. The manual input of harvesting oak leaves will increase the cost and increase the pressure of labor force. This is in line with the goal of modern agricultural production to pursue low cost, labor saving and high profit. Run in the opposite direction

[0004] At present, tussah silkworms are easy to be harmed by wind, rain, low temperature, insects, birds, animals, etc. in the wild; and if indoor breeding is adopted, the plucking of eucalyptus leaves is required. Equipment costs, on the other hand, due to the difficulty in storing and keeping fresh eucalyptus leaves after picking, they are easy to wither, the leaf quality decreases, and the breeding performance is affected; Limits the natural properties of tussah silkworms such as uprightness and fugitiveness

At the same time, intensive rearing on the plane is conducive to the reproduction, enrichment and spread of pathogens. Therefore, silkworms are prone to disease, and must have a high level of technical management. Frequent disinfection and disease prevention increase the difficulty and cost of disease prevention.
