[0002] Through artificial selection and modern biotechnology, such as mutagenesis, hybrid breeding, protoplast fusion technology and genetic engineering breeding, Ganoderma lucidum strains with excellent characteristics can be bred. These strains usually have the characteristics of vigorous mycelial growth, strong adaptability, and strong resistance to adverse external environments, thereby ensuring the yield and quality of Ganoderma lucidum. Under appropriate culture conditions, such as temperature, humidity, light, etc., Ganoderma lucidum strains can grow and reproduce stably, thereby ensuring the stability of Ganoderma lucidum's yield and quality. Through Ganoderma lucidum strain cultivation, the uncertainty brought about by directly collecting strains from wild Ganoderma lucidum can be avoided, such as inconsistent strain quality and susceptibility to diseases and pests, thereby reducing cultivation risks. Ganoderma lucidum strain cultivation provides a large number of high-quality strains for the Ganoderma lucidum industry, which is conducive to large-scale production and market promotion of the Ganoderma lucidum industry.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) When the device is used to cultivate Ganoderma lucidum, the culture box is directly placed in the culture main tank through the culture main tank during cultivation, and the constant temperature is maintained by a water bath. Compared with the air conditioning temperature control system, the temperature inside the culture medium placed in the culture box can be ensured to avoid a certain temperature difference between the inside and the outside, so as to better play a temperature control role and improve the survival rate of Ganoderma lucidum. In addition, the water bath constant temperature can be kept uniform by stirring during use, so as to avoid different water temperatures in the culture main tank during the heating process, which affects the growth environment of Ganoderma lucidum, thereby improving the survival rate of Ganoderma lucidum and better cultivating Ganoderma lucidum for use;

[0021] (2) At the same time, a stable clamping plate is also provided in the culture main body tank. When the culture box is placed in the culture main body tank for constant temperature heating in a water bath, the culture box placed in the culture main body tank is easily shaken due to the stirring of the water flow. Through the function of the stable clamping plate, after the culture box is placed, the culture box can be clamped and stabilized in the culture main body tank by the stable clamping plate, so as to avoid the culture box shaking unsteadily during the water temperature stirring and heating process, thereby affecting the survival of the Ganoderma lucidum strains.

Then, the magnetic frame cover is embedded in the embedded groove on the top of the culture box to ensure that the breathable and moisturizing non-woven fabric is stably covered on the top of the culture box. At the same time, it is also convenient to disassemble and replace the breathable and moisturizing non-woven fabric. The breathable and moisturizing non-woven fabric is disposable after cutting. After the breathable and moisturizing non-woven fabric is covered, water mist can be sprayed regularly and quantitatively through the atomizing nozzle. The water mist falls on the breathable and moisturizing non-woven fabric to ensure the humidity of the matrix in the culture box and avoid water mist being directly sprayed on the matrix to affect the cultivation effect of Ganoderma lucidum. In addition, the humidity of the matrix in the culture box is ensured by wetting the breathable and moisturizing non-woven fabric, which can better cultivate Ganoderma lucidum, thereby improving the practicality of the device.
