Embodiment Construction

[0022] The following is further described in detail through specific implementation methods:

[0023] A method for cultivating selenium-enriched silkworm chrysalis, comprising the following steps:

[0024] (1) select the healthy silkworm larvae of the 3rd instar stage, put the silkworm larvae into the breeding box for subsequent use;

[0025] (2) Select fresh, non-rotten, fresh and tender mulberry leaves without damage, remove the upper petiole of the mulberry leaves and wash and dry the mulberry leaves;

[0026] (3) to the mulberry leaf surface of step (2), uniform spraying concentration is the aqueous solution containing selenide of 2-500mg / L, and selenium compound solution is preferably sodium selenite or selenized organic compound aqueous solution in the present embodiment, sprays The amount of the selenium compound aqueous solution is 8-10% of the weight of the mulberry leaves, and the mulberry leaves are placed at room temperature until the solution does not drip, and t...

Abstract

The invention belongs to the technical field of agricultural culture, and specifically discloses a culture method of selenium-enriched silkworm chrysalis. The method includes the following steps: (1)selecting healthy silkworm larvae of 3 ages for standby; (2) selecting fresh, well and tender mulberry leaves without damage; (3) uniformly spraying a selenide-containing aqueous solution with a concentration of 2-500mg / L on the surface of the mulberry leaves in the step (2), and drying the mulberry leaves in the shade to obtain selenium-combined mulberry leaves; (4) feeding the silkworm larvae inthe step (1) with the mulberry leaves obtained in the step (3); (5) spinning and cocooning the mature silkworm in the step (4), picking silkworm cocoons after pupation, and cutting the silkworm cocoons to obtain silkworm chrysalis; and (6) carrying out low-temperature hot air drying or direct low-temperature freezing preservation on the silkworm chrysalis in the step (5) to obtain selenium-enriched silkworm chrysalis, and further preparing multiple other delicious foods or raw materials. The method is mainly used for acquiring silkworm chrysalis containing organic selenium and improving the added value and health care value.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and specifically discloses a breeding method for selenium-enriched silkworm chrysalis. Background technique [0002] Selenium is one of the essential trace elements for the human body. It is closely related to more than 40 major diseases of the human body, and indirectly related to more than 400 diseases. Supplementing selenium in an appropriate amount can prevent cancer and other diseases. And now my country is now a serious selenium-deficient country, with 72% of the areas selenium deficient, of which 30% of the areas are seriously deficient in selenium, especially the parts of 15 provinces, municipalities and autonomous regions from the northeast to the southwest constitute the "selenium-poor zone". Therefore, the function of selenium is highly valued by unprecedented human beings. [0003] Silkworm chrysalis is high in protein content, rich in amino acid composition, and rich i...
