Background technology
Xingbao mushroom is called perverse celery and is picked up the ears, and is under the jurisdiction of the Basidiomycetes in the Eumycota, is that the rare edible mushroom new varieties edible, medicinal, dietotherapy that integrate are successfully cultivated in the China recent years exploitation.Xingbao mushroom has almond flavor, and not only meat is plump, fresh and tender, the taste delicate fragrance of mouthfeel, and nutritious.Research shows, mineral matters such as Xingbao mushroom rich in proteins, carbohydrate, vitamin and calcium, magnesium, copper.In addition, Xingbao mushroom also have reducing blood lipid, norcholesterol, promotion gastro-intestinal digestion, enhancing body immunocompetence, anticancer, prevent effects such as cardiovascular disease and beauty treatment.
In order further to improve the quality of Xingbao mushroom; Enrich its nutrient component; In the cultivation process of present stage Xingbao mushroom, can add the nutrient solution that some contain trace element usually, utilize the biological transformation of Xingbao mushroom then, the trace element in the nutrient solution is converted into self own.Because zinc is one of teleorganic trace element; It is the catalysis factor of the many activated acids of human body; Participate in planting surplus in the of 300 in the body composition of acid and functional protein; Has biochemical functions widely; So when Xinbao mushroom culturing, generally add the inorganic zinc nutrient solution at present; Utilize the metabolism of Xingbao mushroom to transform then, inorganic zinc is attached on self the macromolecular substances (like polysaccharide and protein) and forms organic zinc and carry out enrichment.But present culture technique can't impel Xingbao mushroom to absorb the conversion zinc element efficiently, makes that the content of the interior organic zinc of its body is lower, can't further improve the nutritional quality of Xingbao mushroom.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of culture technique of Xingbao mushroom, make this culture technique can improve organic zinc content in the Xingbao mushroom.
For realizing above-mentioned purpose, the present invention provides following technical scheme:
A kind of culture technique of Xingbao mushroom is with 1.5-2.5 μ w/cm
2The ultraviolet light of intensity, every Xingbao mushroom bacterium 5-15min that is inoculated on the medium at a distance from the 2.5-3.5h irradiation is covered by the Xingbao mushroom mycelia to medium entirely, and adding inorganic zinc nutrient solution is ripe to Xingbao mushroom in medium then.
Wherein, judge whether medium is covered by the Xingbao mushroom mycelia entirely and whether Xingbao mushroom is ripe, is known to those skilled in the art.The method of inoculation Xingbao mushroom bacterium is this area routine techniques means, and the Xingbao mushroom bacterial classification can be through commercially available acquisition.
Xingbao mushroom can form some novel proteins when containing the coercing of zinc element mineral salt or make that some albumen is synthetic to be strengthened receiving, and these albumen are called the salt stress protein, and they can combine zinc ion to form zinc albuminate.But existing culture technique can't make the salt stress protein efficiently combine zinc ion, makes that organic zinc (the being zinc albuminate) content in the Xingbao mushroom is lower.
Therefore, the present invention uses the ultraviolet irradiation Xingbao mushroom earlier, and then adds the inorganic zinc nutrient solution, is preferably by mass volume ratio 1kg: 4mL, in medium, adds the inorganic zinc nutrient solution every day one time.Wherein, said inorganic zinc nutrient solution comprises that mass fraction is that 0.4-0.5% zinc sulphate and mass fraction are the 7-9% medical stone, and surplus is a water, is preferably to comprise that mass fraction is that 0.45% zinc sulphate and mass fraction are 8.6% medical stone, and surplus is a water.
Ultraviolet ray can make Xingbao mushroom strengthen synthetic salt adverse circumstance to combine the zinc ion ability, and then adds the inorganic zinc nutrient solution, impels zinc albuminate synthetic in a large number, makes Xingbao mushroom effectively absorb zinc element, and is converted into organic zinc and carries out enrichment.Can damage mycelia because uitraviolet intensity is too high, cross the low poor effect that zinc ion is absorbed of then inducing, the strength control of said ultraviolet light according to the invention is at 1.5-2.5 μ w/cm
2, be preferably 2 μ w/cm
2In the specific implementation, the present invention can adopt the uviol lamp of 40w, is suspended on 20 bag culture mediums, and distance is 40cm.Wherein, the irradiation frequency of said ultraviolet light is preferably every at a distance from 3h irradiation 10min.
Medium according to the invention is that 39.4% water, mass fraction are that 36.4% cotton seed hulls, corncob, straw or wood chip, mass fraction are that 12.1% wheat bran, corn flour or rice bran and mass fraction are that 12.1% cottonseed oil meal or sunflower oil meal are formed by mass fraction preferably, is that 39.4% water, mass fraction are that 36.4% cotton seed hulls, mass fraction are that 12.1% wheat bran and mass fraction are that 12.1% cottonseed oil meal is formed by mass fraction more preferably.
The present invention also provides a kind of Xingbao mushroom of being planted out by culture technique according to the invention.Xingbao mushroom according to the invention is through the organic zinc content detection, be the conventional cultivation technology Xingbao mushroom of planting out organic zinc content 36-40 doubly, show that culture technique according to the invention can significantly improve Xingbao mushroom organic zinc content.
Can be known that by above technical scheme culture technique according to the invention is through adopting the uv induction technology, making Xingbao mushroom fully transform inorganic zinc is organic zinc, has significantly improved its organic zinc content, has improved the nutritional quality of Xingbao mushroom.
