Problems solved by technology

At present, most of the Ganoderma lucidum in my country is cultivated in greenhouses, which generally pay more attention to the control of temperature and humidity, but do not pay attention to light.

Embodiment 1

[0035] A method of using light to realize high-yield and high-quality cultivation of Ganoderma lucidum. During the entire cultivation process of Ganoderma lucidum, the growth and development state of the mycelium of Ganoderma lucidum is changed through the control of different wavelengths of light. The method is the same as the existing ganoderma cultivation method. In this example, Ganoderma lucidum No. S3 strain was used, which was obtained from the Biotechnology Center of the Institute of Medicinal Botany, Chinese Academy of Medical Sciences. The Ganoderma lucidum cap is relatively large, and the yield of spore powder is moderate. The cultivation site is selected as the Ganoderma lucidum base in Changping, Beijing. The process of utilizing light includes the following steps:

[0036] (1) Evenly distribute LED light sources with different light quality treatments on the top of the culture rack, adjust the height of the culture rack, keep the distance between the light sourc...

Embodiment 2

[0044] In this embodiment, the method of using light to realize high-yield and high-quality cultivation of Ganoderma lucidum is the same as that in Embodiment 1. In this example, the Ganoderma lucidum strain from Mount Tai was used for cultivation in the Ganoderma lucidum base in Guan County, Shandong Province.

[0045] Compared with the substituting cultivation Ganoderma lucidum (Ganoderma lucidum strain) that does not undergo the above-mentioned light treatment, after adopting this method, harvesting 10 days in advance, the Ganoderma lucidum polysaccharide content of the obtained Ganoderma lucidum increased by 17.6%, the total triterpenoids of Ganoderma lucidum increased by 23.3%, and the yield of Ganoderma lucidum 8.1% increase and 7.2% increase in spore meal production.

Embodiment 3

[0047] A method of using light to realize high-yield and high-quality cultivation of Ganoderma lucidum. During the entire cultivation process of Ganoderma lucidum, the growth and development state of the mycelium of Ganoderma lucidum is changed through the control of different wavelengths of light. The method is the same as the existing ganoderma cultivation method. In this example, Shanghai Ganoderma lucidum No. 1 strain was used, which was purchased from the Institute of Edible Fungi, Shanghai Academy of Agricultural Sciences. This strain has the characteristics of high spore powder production, and was cultivated in Longquan Ganoderma lucidum base in Zhejiang Province using large sections of wood. The process of utilizing light includes the following steps:

[0048] (1) Evenly distribute LED light sources with different light quality treatments on the top of the culture rack, adjust the height of the culture rack, keep the distance between the light source and the culture ma...

Abstract

The invention discloses a method for high-yield and high-quality culture of lucid ganoderma with application of light and relates to the technical field of medical fungi culture. According to the invention, control with light of different wavelengths is applied during the whole culture course of lucid ganoderma, and LED lamps with different colors are used as light sources; or, different light qualities are obtained through placement of a filter coating on a culture object under a common light source or natural light. Through regulation and control of different light qualities, growth and development states of lucid ganoderma hyphae could be changed. On one side, growth speed of lucid ganoderma is increased. On the other side, the contents of effective constituents in lucid ganoderma (ganoderan and ganodenic acid) are increased. Hence, the growth cycle of lucid ganoderma is increased, and lucid ganoderma quality is improved. According to the invention, the method is simple; the cost is low; the lucid ganoderma cultured by the method has higher commodity values; and significant economic benefits can be obtained.

Description

technical field [0001] The invention relates to the technical field of cultivation of medicinal fungi, in particular to a cultivation method of ganoderma lucidum. Background technique [0002] Light is an important environmental factor. It has become a mature technology in the field of protected cultivation to improve the morphogenesis, growth and development, and accumulation of active ingredients of plants by adjusting light quality. Unlike plants, light mainly acts as an environmental signal rather than an energy factor, affecting fungal morphogenesis, individual and community distribution, membrane potential changes, physiological cycles, gene expression, and sexual reproduction. Ganoderma lucidum is a traditional precious Chinese medicine. It has been used medicinally for more than 2,000 years in my country, and it has been regarded as a treasure for prolonging life. Its fruiting body, spore powder, and mycelium all have medicinal value. Ganoderma lucidum contains pol...
