Embodiment 1

[0018] (1) Soak the silkworm eggs in 75% ethanol and 4% formaldehyde solution for disinfection and sterilization during the lighting period or before the lighting period;

[0019] (2) The silkworm eggs after the disinfection and sterilization are incubated in a sterile isolator, which includes several horizontal feeding trays, and the sterile isolator keeps the incubation process in place. Carry out in the dark, the incubation process maintains a constant temperature of 25°C and a humidity of 70-80%. For the entire aseptic isolator, the transmission rate of the aseptic treated air is 250-350 liters / day , Until the sterile ant silkworm is obtained;

[0020] (3) Feed the sterile ant silkworms hatched in the sterile isolator with sterilized artificial feed. The sterilized artificial feed is the artificial feed that is sterilized by high-pressure steam and then makes up for the loss due to sterilization. Vitamins are obtained, wherein the sterilized artificial feed comprises: based on...

Abstract

The invention provides a method for cultivating sterile silkworm insect grass. The method comprises the steps that silkworm eggs in the head pigmentation stage or before the head pigmentation stage are disinfected and sterilized; the disinfected and sterilized silkworm eggs are placed in a sterile isolator to be hatched; sterile newly-hatched silkworms which are hatched in the sterile isolator are fed with sterile artificial feed; cordyceps militaris bacterium liquid is prepared; the cordyceps militaris bacterium liquid is injected into abdominal cavities of the sterile silkworms of the third to fifth day of five ages; died and stiff sterile silkworms which grow a small amount of hyphae are taken out from a raising plate and then transferred into a sterile environment alternating illumination at 25 DEG C in the daytime with dark at 20 DEG C at night to be cultivated for 38-42 days, the environment humidity is kept 95% or above in the cultivating process, and then the sterile silkworm insect grass of which the whole body completely grows the hyphae and sporophores of different lengths is obtained.

Description

technical field [0001] The invention relates to the cultivation of silkworm fungus, in particular to aseptic cultivation of silkworm fungus. Background technique [0002] Cordyceps sinensis, also known as Cordyceps sinensis, is a precious nourishing medicinal material commonly used by Chinese folks. Its nutritional content is higher than that of ginseng. It can be used as medicine or edible. It is an excellent delicacy with high nutritional value. Because of the cordycepin contained in it, Cordyceps can enhance the body's immunity, nourish the lungs and kidneys, and have obvious inhibitory effects on lung cancer and liver cancer. Clinically, it has curative effects on chronic cough due to lung deficiency, asthma, hemoptysis due to tuberculosis, night sweat, waist and knee pain due to kidney deficiency, impotence and nocturnal emission, neurasthenia, and red blood cell drop after chemotherapy and radiotherapy. The content of cordycepin has become an important indicator of th...
