Method for cultivating lucid ganoderma
[technical field]
The present invention relates to a kind of culturing edible fungi, relate in particular to a kind of ganoderma lucidum cultivation method that has used new cultivation material.
[background technology]
Glossy ganoderma is the well-known medicinal fungi of China, and ancient books Shennong's Herbal, " The Master of Preserving Simplicity " and Compendium of Material Medica all have in various degree description and record to the classification of glossy ganoderma and effect.Modern medicine study proves, the polyose in the glossy ganoderma, triterpenes, sterols isoreactivity composition have antitumor, as to regulate immunity, nervous system regulation, the adjusting recycle system etc. function to human body.Therefore domestic the world of medicine is very interested in the research of glossy ganoderma, and all kinds of healthcare products processed goods that contain effective component of glossy ganoderma are also successfully developed, and the enterprise that is engaged in Garnoderma product also arises at the historic moment, and those ganoderma lucidum prods of succeeding in developing are constantly released market.In the middle of whole ganoderma lucidum prod industry, a most primary ring is the cultivation of glossy ganoderma, and the quality of cultivating ganoderma directly influences the quality of its downstream converted products.Learn that according to State Intellectual Property Office of the People's Republic of China's in July, 2009 retrieval the patent relevant with " glossy ganoderma " has 889.But 30 of wherein relevant patent less thaies with the Ganoderma sporophore cultivation.The tame cultivation material of modern glossy ganoderma is with wood chip, the Duan Muwei master of leaf wood.Report with the napier grass cultivating ganoderma was arranged in 2000: it is suitable that water-soluble polysaccharide in the Ganoderma sporophore that grass carries and total amino acid content and wood are planted glossy ganoderma, and mineral element content, lipid acid kind number and vitamin B group are all planted glossy ganoderma a little more than wood, and visible grass carries glossy ganoderma also certain application prospect.In addition, can be used as the cotton seed hulls that also has of cultivation of glossy ganoderma material, but be that the cultivation material easily causes the too high and carbon under-nutrition of nitrogen element nutrition with the cotton seed hulls.In addition, bagasse, Rhizoma Dioscoreae powder, wheat, vinasse etc. all have record to can be used for cultivating ganoderma in some monograph, but still find no the periodical literature support at home.The main marsupial of cultivation of glossy ganoderma mode plants, bottle is planted and segment wood cultivated etc.
In traditional concept and pertinent literature in the past, because eucalyptus contains fragrant hydrocarbon system material, usually eucalyptus and seeds such as the pine that is not suitable for cultivating ganoderma, China fir, camphor tree are equated, think that it also is unwell to cultivating ganoderma.
Along with the development of making plate, paper-making industry, the timber resources demand increases, and adds that State Council has ratified each provinces, autonomous regions and municipalities year forest harvesting limit the Eleventh Five-Year Plan period in 2005, and traditional broad-leaved timber cost that can cause being used for cultivating ganoderma raises; In addition, the seeds of Song Shan one class, it is wooden to contain the material that perfume oil, resin etc. are unfavorable for the glossy ganoderma growth, causes the wood resources acquisition approach that can be used in cultivating ganoderma to become narrow and small and nervous.And, make eucalyptus become a kind of cheap raw material along with a large amount of plantations of eucalyptus in recent years.
[summary of the invention]
The present invention aims to provide a kind of glossy ganoderma growth cycle method for cultivating lucid ganoderma fast, with low cost.
Method for cultivating lucid ganoderma of the present invention contains eucalyptus in its cultivation material.Wherein, the bark or tree bar or the bark tree bar mixture that more preferably contain eucalyptus.And more preferably the cultivation material is the wheat bran of the eucalyptus wood chip of quality percentage composition 73-83%, quality percentage composition 15-25%, the CaCO3 of quality percentage composition 2%.Most preferred cultivation material is the eucalyptus wood chip of quality percentage composition 73-83%, the wheat bran of quality percentage composition 15-25%, the CaCO of quality percentage composition 2%
