Cordyceps sinensis strain collecting device and method

Abstract

The invention discloses a cordyceps sinensis strain collecting device and method. The device comprises a water collecting tank, a pipeline, water seepage pipes, a collecting box, an isolator, multiplegrowth holes and a sprayer head; the water collecting tank is located above the collecting box, and connected with the pipeline, and the pipeline leads to the upper position and the side face of thecollecting box separately; the collecting box is of a cuboid structure with a normally-opened top; the isolator is located in the middle inside the collecting box, and the growth holes running throughthe isolator are formed in the isolator, and make the bottom of the collecting box communicated with the space of the upper portion of the isolator; the sprayer head is connected to the end, leadingto the upper position of the collecting box, of the pipeline; the two water seepage pipes are connected to the end, leading to the side face of the collecting box, of the pipeline, and stretch into the lower position of the isolator in the collecting box. By means of the device, favorable conditions are created for cordyceps sinensis to infect larvae of hepialus armoricanus, so that more cordycepssinensis is cultured; meanwhile, through the arrangement of the isolator, the cordyceps sinensis is isolated from other infectious microbes, the success rate of infecting the larvae of hepialus armoricanus by cordyceps sinensis is increased, and the humidity of a medium is automatically controlled.

Description

technical field [0001] The invention relates to the technical field of collecting Cordyceps strains, in particular to a device for collecting Cordyceps strains and a collection method using the device. Background technique [0002] The bat moth is the main host insect of the fungus Cordyceps sinensis, and the life habits of the adults mainly reproduce through reproductive activities such as mating and egg laying. The life cycle of the bat moth is as long as 4 years or more, the larvae period is as long as 3 years or more, the adult period is shorter, about 25-28 days, and the individual survival period is generally 3-4 days. The Cordyceps fungus invades the host bat moth larvae in July and August every year, and makes full use of the nutrition of the insect body to multiply the hyphae and even fill the entire body cavity. Infected larvae burrow into the soil and survive the winter. Around October, when the ground temperature is 2-9°C, the larvae die and become zombified ins...
